Do not disconnect while circuit is live unless area is known to be non-hazardous.
Power Over Ethernet (PoE) Models
The 1-port/4-port SDS P models can be powered by either the external DC power supply (not included) or PoE or both. The 2-port SDS P does not accommodate an external power supply and can be powered only through PoE.
The IOLAN SDS P model is considered a Powered Device (PD) and can only accept power from an IEEE 802.3AF compliant Power Source Equipment (PSE) device. The IOLAN PoE can receive up to 13W of power using one of the following methods to connect to a PSE:
- Using the two unused twisted pair wires (10/100Mb only).
- Using the two data pairs or “phantom power” method (100Mb).
I/O Models
The power supply for a desktop IOLAN I/O model must meet the following requirement:
• Output between 9-30VDC and a minimum of 600mA current.
- 20 AWG wire.
Note: The maximum load for the Relay channel is 1A @ 30VDC or 0.5A @ 120 VAC.
Rack Mount Models (except Electric Utility models)
DC Power Requirements
The IOLAN DC is supplied with an integral Terminal Connections block to facilitate connection to a DC source(s). The DC supply(s) should have adequate over-current protection within the closed rack system and comply with local or national standards applicable to the installation territory. You need wire gauge 20 to 22 AWG to connect the IOLAN rack mount unit to the power source.
Note:
The equipment must be grounded for safety and to ensure ESD protection for correct operation and protection of the internal circuitry.
Note:
WARNING
Before servicing this product ensure the power source has been disconnected. For dual input or dual power supply models, ensure both sources have been disconnected.

Electric Utility Models
Power Options
The Electrical Utility series of IOLAN units can be purchased with three different power source options;
HV - Single High Voltage power input with nominal AC range of 100V-240V (50-60Hz) or nominal DC range of 125V-250V.
DHV - Dual redundant High Voltage power inputs with nominal AC range of 100V-240V (50-60Hz) or nominal DC range of 125V-250V. Either power source can be used to supply power to the unit. When both power inputs are live, the unit operates in a load sharing fashion. Note that the power input pairs are electrically isolated from each other. This means that when using both power inputs either input can be in either the AC or DC range.
LDC - Dual, low voltage DC power inputs with nominal range of 24V-60V. The power supply can be fed by either source1 or source 2 or both. When both power inputs are live, the unit selects the input with the highest voltage. The other input is not used unless it becomes the highest voltage at some point, in which case the unit will switch to it. No power loss will occur during a switch over.
DC Power Requirements

Located at the back of the desktop IOLAN models is a switch that controls whether serial port 1 is in Console or Serial mode.
Note: The SDS T (Extended Temperature) models have two switches, Switch 1 is used for Console/Serial mode and Switch 2 is unused.

natural_image
Back view of a black electronic device showing port, socket, and internal components (no visible text or symbols)Look at your model to verify the direction of the ON switch position. ON indicates that serial port 1 is in Console mode; otherwise serial port 1 is in Serial mode.
Console Mode
Console mode is used when you have a direct connection between a serial device (like a terminal or a PC) and the IOLAN, accessed by the admin user to configure/manage the IOLAN. Console mode automatically sets serial port settings as:
- Serial Interface to EIA-232
- Speed to 9600
• Flow Control to No - Bits to 8
- Stop Bits to 1
Parity to None
Console mode also displays extra system messages.
Serial port 1 will ignore any Serial Port settings when in Console mode, so you need to turn Console mode off to use serial port 1 in your network.
Note: When the console switch is in the on position, the Power/Ready LED will blink green.
Serial Mode
Serial mode is used when the IOLAN acts as a communications server, or anytime you are not connecting directly to the IOLAN to configure it. You can connect directly to the IOLAN in Serial mode, but the IOLAN will not display all the messages/information you will get in Console mode.
Dedicated Console Port
The rack mount IOLAN models have a dedicated Console port, located on the LED side of the IOLAN. You can use the supplied Administration cable (with the supplied RJ45→DB9F adapter if needed) to connect a terminal to the Console/Admin port to view diagnostic information and/or configure the IOLAN using the Menu or Command Line Interface (CLI). You can configure the baud rate and flow control of the dedicated Console port.
Connecting your IOLAN to the Network
To connect the IOLAN to the network, use a straight-through two-pair Category 5 unshielded twisted-pair (UTP) cable, or four-pair for Gigabit connections. Connect the RJ-45 Ethernet port on the IOLAN to a switch, hub, repeater, server or other network device To connect IOLAN SCS16C-DSFP models, see Inserting SFP modules into SPF slots.
Note: To comply with the Telcordia GR-1089 NEBS standard, connect Ethernet interfaces only to intra-building or unexposed wiring or cabling. The intra-building cable must be shielded and the shield must be grounded at both ends.
Alternatively, if shielded cabling is not used, the Ethernet wiring (cabling) must directly connect to equipment within the same frame, cabinet or line-up and the equipment must be separated by a distance of 6 meters or less.
Note:
WARNING
The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

3Configuration Methods
Introduction
This chapter provides information about the different methods you can use to configure the IOLAN. Before you can configure the IOLAN, you must assign an IP address to the IOLAN. See the Getting Started to find out how to assign an IP address to the IOLAN.
Once an IP address is assigned to the IOLAN, you can use any of the configuration methods to:
- Configure users.
- Configure IOLAN server parameters.
- Configure serial port parameters.
- Configure network parameters.
- Configure time parameters.
- Reboot the IOLAN.
- Manage the Perle Remote Power Switch (when applicable).
- Manage I/O channels (when applicable).
- Restart WLAN and LTE connectivity.
• View statistics while connected to the IOLAN.
Configuration Methods Overview
Some of the IOLAN configuration methods have the capability of configuring an IP address, which is the first required configuration step for a new IOLAN. Once the IOLAN has been assigned an IP address, any of the configuration methods can be used to configure the IOLAN.
Configures an IP Address
Following is a list of methods for setting the IOLAN IP address and a short explanation of when you would want to use that method:
- Easy Config Wizard—The Easy Config Wizard is available from the CD ROM included with your IOLAN. You can use the Easy Config Wizard to set the IOLAN's IP address and configure serial ports. This configuration method would typically be used when:
- All ports are to have the same configuration.
- Only the most commonly used profiles are required.
- Straightforward application with no advanced functionality required.
- Easy Config is installed on a Windows ^ -based PC with local network access to the IOLAN.
- DeviceManager—Use this method when you can connect the IOLAN to the network and access the IOLAN from a Windows® PC. The DeviceManager is a Windows®-based application that can be used for IOLAN configuration and management. The DeviceManager can be used to assign an IP address and perform the complete configuration and management of the IOLAN.
- Direct Connection—Use this method when you can connect to the IOLAN from a serial terminal or from a computer running terminal emulation software over a serial port. Using this method, you will need to configure and/or manage the IOLAN using either the Menu or CLI.
- DHCP/BOOTP—Use this method when you have a BOOTP or DHCP server running and you can connect the IOLAN to your network. The IOLAN will automatically obtain an IP address from a local network DHCP/BOOTP server when this service is enabled (it is disabled by default). You can also configure certain IOLAN parameters that will be passed from the DHCP/BOOTP server to the IOLAN when it boots up. Other configurators such as DeviceManager, CLI, or Menu can be used to set this option, and obtain the initial IP address.
- ARP-Ping—Use this method when you can connect the IOLAN to the network and want to assign a temporary IP address to the IOLAN by adding an ARP entry to your PC and then pinging it.
- IPv6 Network—When the IOLAN is connected to an IPv6 network, its local link address is determined using stateless auto configuration.
Once an IP address has been assigned to the IOLAN, in most cases, you can continue to use the same method if it is a configurator or you can switch to any other configuration method.
Requires a Configured IP Address
The following configuration methods require that an IP address already be assigned to the IOLAN.
- WebManager—WebManager is a fully functional, browser-based configuration method.
- IOLAN+ Interface—The IOLAN+ interface is available on IOLAN models that are 1-16 ports (this is not supported on DS1, TS2, and medical unit models) and uses the interface that is available on the IOLAN+ product line.
Easy Config Wizard
The Easy Config Wizard is a configuration wizard that will configure all the serial ports on your IOLAN to one of the following:
- Console Management
• TruePort (Virtual COM Port) - TCP Sockets (Raw TCP)
- Terminal
• Printer (not supported on DS1/TS2 models) - Serial Tunneling
You can launch the Easy Config Wizard from the Perle website or from the installation CD-ROM.

DeviceManager
Overview
The DeviceManager is a Windows ^® -based application that can be used to connect to the IOLAN to actively manage and configure it or can create new IOLAN configurations offline. See Using DeviceManager and WebManager for information on configuring/managing the IOLAN with DeviceManager.
Access Platforms
The DeviceManager can be run from Microsoft, Windows NT ^® /Windows 2000 ^® /Windows Vista ^® /Windows Server 2003 ^® /Windows 2003 R2 ^® /Windows 2008 ^® /Windows 2008 R2 ^® /Windows XP ^® /Windows 7 ^® /Windows 8 ^® /and Windows Server 2012 ^® .
DeviceManager can be installed from the product CD-ROM or downloaded from the Perle website. Unless the IOLAN has already been configured with a Gateway, DeviceManager can only access IOLANs in the local subnet. The DeviceManager can be accessed by only the admin user.
Features
DeviceManager supports the following features:
- The ability to download the same configuration file to several IOLANs in one operation.
- The ability to save a configuration file locally in text format, in addition to the binary format.
- The ability to create a configuration file without being connected to the IOLAN.
- The ability to open a session to the IOLAN and download a (saved) configuration file to it.
- The ability to download/upload keys/certificates to/from the IOLAN.
- The ability to download custom files, such as new terminal definitions and a custom language files to the IOLAN.
Connecting to the IOLAN Using DeviceManager
Before you can use DeviceManager, you need to install it on your Windows operating system from the IOLAN CD-ROM or you can download it from the Perle website. After the DeviceManager application is installed, click Start, All Programs, Perle, DeviceManager, DeviceManager to start the application. When you launch the DeviceManager, it will scan the network for IOLANs:

Command Line Interface
Overview
The Command Line Interface (CLI) is a command line option for IOLAN configuration/management. See the Command Line Interface Reference Guide for a full breakdown of all the CLI commands and their functionality.
Access Platforms
The CLI is accessed by any application that supports a Telnet or SSH session to the IOLAN's IP address, such as Putty, SecureCRT, or from a command prompt. You can also access the CLI from a dumb terminal or PC connected to a serial port.
Features
The CLI supports the following features:
- You can access the IOLAN from any application that supports Telnet or SSH.
- The ability to clear the ARP table (cache).
- The ability to save a configuration file locally in text format, in addition to the binary format.
- For existing IOLAN+ customers, the native IOLAN+ CLI to be used by entering the iolan+ command. See your IOLAN User's Guide for information on using the IOLAN+ CLI.
Note: The IOLAN+ CLI is not supported on IOLAN models with more than 16 ports or the DS1/TS2 and medical unit models.
Connecting to the IOLAN Using the CLI
There are two ways you can access the IOLAN, through the network (Ethernet connection) or through the serial connection. If you are accessing the IOLAN through the network, the IOLAN must already have a known IP address configured; see Using a Direct Serial Connection to Specify an IP Address for information on configuring an IP address.
Through the Network
To connect to the IOLAN through the network to configure/manage it using the CLI, do the following:
- Start a Telnet or SSH session to the IOLAN's IP address; for example:
telnet 10.10.201.100 - You will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights. If the login is successful, you will get a prompt that displays the IOLAN model and number of ports:
Login: admin Password:
SDS2#
You will see a prompt that displays the model and number of the IOLAN. You are now ready to start configuring/managing your IOLAN using the CLI.
Through the Serial Port
To connect to the IOLAN through the serial port to configure/manage it using the CLI (or Menu), see Using a Direct Serial Connection to Specify an IP Address.
After you have established a connection to the IOLAN, you will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights. If the login is successful, you will get a prompt that displays the IOLAN model and number of ports:
Login: admin
Password:
SDS2#
You will see a prompt that displays the model and number of the IOLAN. You are now ready to start configuring/managing your IOLAN using the CLI
Using the CLI
After you have successfully logged in, you can start configuring/managing the IOLAN by typing in commands at the prompt. If you are not sure what commands are available, you can type a ? (question mark) at any time during a command to see your options.
See the Command Line Interface Reference Guide for more information about the CLI.
Menu
Overview
The Menu is a graphical representation of the CLI. You can look up Menu parameter explanations in the Command Line Interface Reference Guide. The only operations that the Menu does not support are the downloading and uploading of files to/from the IOLAN.
Access Platforms
The Menu is accessed by any application that supports a Telnet or SSH session to the IOLAN's IP address, such as Putty, SecureCRT, or from a command prompt. You can also access the Menu from a dumb terminal or PC connected to a serial port.
Features
The Menu supports the following features:
- You can access the IOLAN from any application that supports Telnet or SSH.
- For existing IOLAN+ customers, the native IOLAN+ menu interface can be used by entering the iolan+ command to display and use the native IOLAN+ menu interface. See your IOLAN User's Guide for information on using the IOLAN+ interface. See IOLAN+ Interface for more information about IOLAN+ interface.

DHCP/BOOTP
Overview
Several IOLAN parameters can be configured through a DHCP/BOOTP server during the IOLAN bootup. This is particularly useful for configuring multiple IOLANs.
Not all configuration parameters are supported in the DHCP/BOOTP configuration (see DHCP/BOOTP Parameters for supported configuration parameters), so you will need to use another configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.
Features
DHCP/BOOTP supports the following features:
- DHCP/BOOTP can supply the IOLAN's IP address.
- The DHCP/BOOTP server can configure certain server and user configuration parameters when the IOLAN is booted.
- The DHCP/BOOTP server can auto-configure the IOLAN with basic setup information (IP address, subnet/prefix bits, etc.).
- The DHCP/BOOTP server can download a new version of firmware when the IOLAN is rebooted.
- The DHCP/BOOTP server can download a full configuration file when the IOLAN is rebooted.
Connecting to the IOLAN Using DHCP/BOOTP
The IOLAN will automatically request an IP address from the DCHP/BOOTP server when the Obtain IP address automatically using DHCP/BOOTP parameter is enabled. To enable the Obtain IP address automatically using DHCP/BOOTP parameter, follow the directions in Using a Direct Serial Connection to Enable BOOTP/DHCP.
Using DHCP/BOOTP
To use DHCP/BOOTP, edit the bootp file with IOLAN configuration parameters. You can use DHCP/BOOTP to perform the following actions on a single or multiple IOLANs on bootup:
- auto-configure with minimal information; for example, only an IP address
- auto-configure with basic setup information (IP address, subnet/prefix bits, etc.)
- download a new version of firmware
- download a full configuration file
DHCP/BOOTP is particularly useful for multiple installations: you can do all the IOLANs' configuration in one DHCP/BOOTP file, rather than configure each IOLAN manually. Another advantage of DHCP/BOOTP is that you can connect the IOLAN to the network, turn on its power and let autoconfiguration take place. All the configuration is carried out for you during the DHCP/BOOTP process.
DHCP/BOOTP Parameters
The following parameters can be set in the DHCP/BOOTP bootp file:
- SW_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the firmware update.
- CONFIG_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the configuration file.
- GUI_ACCESS—Access to the IOLAN from the HTTP or HTTPS WebManager. Values are on or off.
- AUTH_TYPE—The authentication method(s) employed by the IOLAN for all users. You can specify the primary and secondary authentication servers, separated by a comma. This uses the following numeric values for the authentication methods.
- 0 —None (only valid for secondary authentication)
- 1 —Local
- 2 —RADIUS
- 3 —Kerberos
- 4 —LDAP/Microsoft Active Directory
- 5 —TACACS+
- 6 —SECURID
- 7 —NIS
- SECURITY—Restricts IOLAN access to devices listed in the IOLAN's host table. Values are yes or no.
- TFTP_RETRY—The number of TFTP retries before aborting. This is a numeric value, for example, 5.
- TFTP_TMOUT—The time, in seconds, before retrying a TFTP download/upload. This is a numeric value, for example, 3.
- CUSTOM_LANG—The full path, pre-fixed by a hostname/IP address (IPv4 or IPv6), and file name of a translated language file. For example, 192.101.34.211 /accounting/Iolan_ds_german.txt.
- EXTRA_TERM1—(EXTRA_TERM2, EXTRA_TERM3) The full path, pre-fixed by a hostname/IP address (IPv4 or IPv6), and file name of a termcap file for a specific terminal type.
SNMP
Overview
The IOLAN supports configuration and management through SNMP. SNMP Management tools (SNMP client/MIB browser software) can be used to set IOLAN configuration parameters and/or view IOLAN statistics.
Before you can configure/manage the IOLAN using SNMP, you need to set the IOLAN IP address and configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2. You can use DeviceManager, CLI, or the Menu to set the IP address and user/community (don't forget to reboot the IOLAN before connecting with the SNMP manager to make your changes take effect).
Access Platforms
You can access the IOLAN SNMP MIB from any system that runs your SNMP client/MIB browser software.
Features
SNMP supports the following features:
- You can configure SNMP traps.
- Since not all versions of SNMP support secure communication, password parameters must be set using another configuration method.
Connecting to the IOLAN Using SNMP
Before you can connect to the IOLAN through an SNMP Management tool or MIB browser, you need to set the following components through another configuration method.
- Configure a known IP address on the IOLAN.
- Configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2 on the IOLAN.
- Reboot the IOLAN to make sure the changes take effect.
To connect to the IOLAN through an SNMP Management tool or MIB browser, do the following:
- Load the perle-sds.MIB file from the IOLAN CD-ROM or Perle website into your SNMP manager (this MIB works for all SDS, SCS, STS, and MDC models).
| Note: | You need to have the following MIBs installed in your SNMP manager (these are usually part of the standard SNMP client/MIB browser):SNMPv2-SMISNMPv2-TCIPV6-TC |
- Verify that the read-write user for SNMP version 3 or a community for SNMP version 1 or 2 match the configuration on the IOLAN.
- Type in the IOLAN's IP address and connect to the IOLAN.
You are now ready to start configuring the IOLAN using SNMP.
Using the SNMP MIB
After you have successfully connected to the IOLAN through your SNMP Management tool or MIB browser, expand the PERLE-IOLAN-SDS-MIB folder to see the IOLAN's parameter folders. Below is an example of the configurable parameters under the ServicesInfo folder.

text_image
PERLE-IOLAN-SDS-MIB.iso.org.dod.int adminInfo serverInfo hostsInfo userInfo portInfo modemInfo servicesInfo serviceStatus serviceDHCP serviceRouteD serviceTelnetD serviceSSHD serviceHTTPD serviceSnmpD serviceSPCD serviceSNTP serviceHTTPSDD serviceSyslog serviceDeviceManagerDThe first variable in each folder is the Status variable, for example, serviceStatus. When you perform a GET on this variable, one of the following values will be returned:
• 1—Indicates that the container folder is active with no changes.
• 2—Indicates that the container folder is active with change(s).
Once you have completed setting the variables in a folder, you will want to submit your changes to the IOLAN. To do this, set the Status variable to 4. If you want to discard the changes, set the Status variable to 6.
4—Indicates that the changes in the container folder are to be submitted to the IOLAN.
6—Indicates that the changes in the container folder are to be discarded.
If you want to save all the changes that have been submitted to the IOLAN, you need to expand the adminInfo container folder and SET the adminFunction to 1 to write to FLASH. To make the configuration changes take effect, SET the adminFunction to 3 to reboot the IOLAN.
IOLAN+ Interface
Overview
For environments that have both IOLAN and IOLAN+ models or for users who prefer to configure using the IOLAN+ Menu or CLI, the IOLAN+ user interface is available. The IOLAN+ interface is supported on all IOLAN SDS, SCS, and STS models up to and including 16 serial ports.
Access Platforms
The Menu is accessed by any application that supports a Telnet or SSH session to the IOLAN's IP address, such as Putty, SecureCRT, or from a command prompt. You can also access the Menu from a dumb terminal or PC connected to a serial port.
Connecting to the IOLAN to Use the IOLAN+ Interface
To connect the IOLAN to using the IOLAN+ interface, follow the directions for Connecting to the IOLAN Using the CLI.
Using the IOLAN+ Interface
After you have successfully logged in to the IOLAN, you can type iolan+ at the CLI command prompt to access the IOLAN+ configuration menu (you must have User Level Normal or Admin).
Note: The IOLAN and the IOLAN+ admin user share the same password. The default admin password is superuser (not iolan).
If you choose to use the IOLAN+ configuration interface, you should always configure the IOLAN using the IOLAN+ interface. The IOLAN/IOLAN+ fields do not map directly between the two interfaces. If you configure a field in the IOLAN configuration interface to a value that is invalid in the IOLAN+ interface and then attempt to use the IOLAN+ interface, the invalid field value will show up as ***** (all asterisks), although the IOLAN will interpret the value as valid.
Changes to the IOLAN+ Interface
You should be aware that the following IOLAN+ configuration fields are no longer supported:
- You no longer have the option of selecting access, Authentication/Logging. Also, kill, reboot, and stats are not available.
- When you select port, the following fields are not available on the Port Setup Menu:

4Getting Started
Introduction
There are several different configuration methods available to configure the IOLAN (see Chapter Configuration Methods for more information). This chapter describes the three main minimal configuration requirements for the IOLAN through either Easy Config Wizard (cannot configure users using this method), DeviceManager, or WebManager:
Note: If you are setting up the IOLAN medical unit (MDC) model, you must first install the latest firmware to take advantage of the full feature set available with the MDC model. The latest firmware can be found either on the CD-ROM that came with the IOLAN or on the Perle website, www.perle.com/downloads (when you access the webpage, select your specific IOLAN model). See Downloading IOLAN Firmware for information on how to download the latest IOLAN firmware.
- Setting up the network—This minimally consists of configuring an IP address or enabling DHCP/BOOTP. Once the IOLAN has an IP address, you can use any configuration method.
- Setting up the serial ports—You will want to select the serial port profile that matches the serial port requirement/scenario for your serial device.
- Setting up users—This is an optional step, which is only required when your implementation requires users to access the IOLAN and you are not using external authentication.
Easy Configuration Wizard
The Easy Config Wizard quickly sets up the IOLAN's network configuration and all serial ports to one of the following:

text_image
EasyConfig Welcome to EasyConfig EasyConfig Wizard discovers and configures IOLAN on a local network to one of the following profiles: - Console Management ( Telnet ) - TruePort ( Virtual Com Port ) - TCP Sockets ( Raw TCP ) - Terminal - Printer - Serial Tunneling For more advanced configurations use WebManager or DeviceManager. Next > Cancel- Console Management—Allows users on the network to connect to a serial device that is connected to a serial port on the IOLAN.
- TruePort (Virtual COM Port)—Allows a networked system to communicate with your serial device through a virtual COM or TTY port, using the Perle TruePort software.
- TCP Sockets (Raw TCP)—Allows hosts on the network to communicate with a serial device that requires raw data throughput (such as a printer or card reader) connected to the IOLAN serial port.
- Terminal—Allows a terminal device to connect to a specified host on the network through a serial port on the IOLAN.
- Printer—Allows hosts on the network to talk to a printer using LPD connected to the IOLAN.
- Serial Tunneling—Allows IOLANs on the network to establish a virtual link between their serial ports. Typically, one IOLAN's serial port is configured as a Tunnel Server and the other IOLAN's serial port is configured as a Tunnel Client.
Setting Up the Network
The most important part of setting up the network is assigning an IP address to the IOLAN, whether this is a static IP address or enabling a DHCP/BOOTP-assigned IP address. You should also assign a name to the IOLAN, to make it easier to recognize. This section deals primarily with setting the IP address.
Using DeviceManager
To use the DeviceManager, you must first install it on a Windows ^® operating system. The DeviceManager is able to automatically discover all IOLANs on your local network, even if they have not yet been assigned an IP address. If routers on the network have been setup to propagate multicasts, DeviceManager will also be able to discover IOLANs in other networks. The DeviceManager installation wizard can be found on the CD-ROM included in the IOLAN package.
- Connect the IOLAN to the network.
- Power on the IOLAN.
- From the CD-ROM that was included in the IOLAN packaging, select the DeviceManager link.
- Click on the link under Location and click Open to automatically start the DeviceManager installation.
- Install the DeviceManager by following the installation wizard. On the last window, check the Yes, I want to launch DeviceManager now. box and click the Finish button.
- When you launch the DeviceManager, it will automatically scan the local network and display any IOLANs that it can find.
- Any IOLAN that does not have an IP address will be displayed as Not Configured, with the Model and MAC Address to identify the IOLAN. Highlight the IOLAN that you want to assign an IP address to and click the Assign IP button.
-
Choose the method you want to use to assign an IP address to the IOLAN:
-
Type in the IP address that you want to assign to this IOLAN.
- Enable the Have the IOLAN automatically get a temporary IP address option. This will turn on DHCP/BOOTP, so the IOLAN will attempt to get its IP address from your DHCP/BOOTP server. If you don't have a DHCP/BOOTP server, DeviceManager will temporarily assign an IP address in the range of 169.254.0.1-169.254.255.255 that will be used only for the duration of the DeviceManager/IOLAN communication.
Click the Assign IP button.
- You are now ready to configure the IOLAN. Double-click the IOLAN you just configured IP address for to open a configuration session. Type superuser (the factory default admin user password) in the Login window and click OK.
- Expand the Server Configuration folder and select Server. Verify the IP address configuration. You should also enter a name in the Server Name field to make the IOLAN easily identifiable.
- To make your edits take effect, you need to download the new configuration file and then reboot the IOLAN. Download the configuration file to the IOLAN by selecting Tools, Download Configuration to Unit or click the Download All Changes button.
- Reboot the IOLAN by selecting Tools, Reboot Server or click the Reboot IOLAN button.
For more information on configuring the IOLAN using DeviceManager, see Chapter Using DeviceManager and WebManager.
Using WebManager
To use the WebManager as your configurator, you must first assign an IP address to the IOLAN. You can use the Easy Config Wizard to assign an IP address to the IOLAN or any of the other methods described in this section. Once the IP address is assigned to the IOLAN, simply type the IP address into the Address field of your web browser and press the Enter key.
Using a Direct Serial Connection to Specify an IP Address
You can connect to the IOLAN's serial console port using a PC with a terminal emulation package, such as HyperTerminal or a terminal.
Note: This procedure does not apply to IOLAN medical unit models.
- Connect the IOLAN to your PC or dumb terminal. Make sure the DIP switch is in Console mode (for desktop models, this sets the IOLAN serial port 1 to EIA-232) or that you are connected to the dedicated Console port (for rack mount models). When connecting a terminal or PC directly (without modems), the EIA-232 signals need to be crossed over ('null modem' cable). See Appendix D, EIA-232 Cabling Diagrams for cabling diagrams.
- Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the Port settings to 9600 Baud, 8 Data bits, No Parity, 1 Stop Bits, and No Hardware Flow control to connect to the IOLAN. You can change these settings for future connections on the rack mount models (the IOLAN must be rebooted for these changes to take place).
- When prompted, type admin for the User and superuser for the Password. You should now see the a prompt that displays the model type and port number; for example, SCS16#.
- You are now logged into the IOLAN and can set the IP address by typing from the command line using the Command Line Interface (CLI).
For single Ethernet connection models, type:
set server internet
For dual Ethernet connection (SCS) models, type:
set server internet eth1
For wireless connection (W) models, type:
set server internet wan0
Where ipv4address is the IP Address being assigned to the IOLAN.
- Type the following command:
save
-
If you are going to use another configuration method, such as WebManager or DeviceManager, unplug a desktop IOLAN or turn Off a rack mount IOLAN. On a desktop IOLAN, change the DIP switch to Off Serial (DIP switch in the up position) and connect it to your serial device. Plug the IOLAN back in, automatically rebooting the IOLAN in the process.
-
If you want to complete the configuration using a direct connection, see Command Line Interface and/or Menu. After you complete configuring the IOLAN, unplug the IOLAN. If this is a desktop model, change the IOLAN DIP switch to Off Serial (DIP switch in the up position) and connect it to your serial device. Plug the IOLAN back in, automatically rebooting the IOLAN in the process.
Using a Direct Serial Connection to Enable BOOTP/DHCP
If you are using BOOTP, you need to add an entry in the BOOTP server for the IOLAN that associates the MAC address (found on the back of the IOLAN) and the IP address that you want to assign to the IOLAN. After you have made the MAC address/IP address association for BOOTP, use the following directions for BOOTP or DHCP.
You can connect to the IOLAN using a PC with a terminal emulation package, such as HyperTerminal or a dumb terminal.
Note: This procedure does not apply to IOLAN medical unit models.
- Connect the IOLAN to your PC or dumb terminal. Make sure the DIP switch is in Console mode (for desktop models, this sets the IOLAN serial port to EIA-232) or that you are connected to the dedicated Console port (for rack mount models). When connecting a terminal or PC directly (without modems), the EIA-232 signals need to be crossed over ('null modem' cable). See Appendix D, EIA-232 Cabling Diagrams for cabling diagrams.
- Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the Port settings to 9600 Baud, 8 Data bits, No Parity, 1 Stop Bits, and No Hardware Flow control to connect to the IOLAN. You can change these settings for future connections on the rack mount models (the IOLAN must be rebooted for these changes to take place).
- When prompted, type admin for the User and superuser for the Password. You should now see the a prompt that displays the model type and port number; for example, SCS16#.
-
You are now logged into the IOLAN and can set the IP address by typing from the command line using the Command Line Interface (CLI). Type the following command:
set server internet dhcp/bootp on -
Type the following command:
save
- Type the following command:
reboot
-
When the IOLAN reboots, it will automatically poll for an IP address from the DHCP/BOOTP server. If the IOLAN has dual Ethernet, each Ethernet connection will automatically be assigned an IP address, you can access the IOLAN through either IP address.
-
To view the DHCP/BOOTP assigned IP address, type the following command:
show interface ethernet
If for some reason it cannot obtain an IP address from your DHCP/BOOTP server, you will have to either reconnect to the IOLAN on the console port and reboot it or push the RESET button to access the IOLAN.
You are now ready to configure the IOLAN. See Chapter Configuration Methods for information on the different IOLAN configuration methods.
Using ARP-Ping
You can use the ARP-Ping (Address Resolution Protocol) method to temporarily assign an IP address and connect to your IOLAN to assign a permanent IP address. To use ARP-Ping to temporarily assign an IP address:
- From a local UNIX/Linux host, type the following at the system command shell prompt:
arp -s a.b.c.d aa:bb:cc:dd:ee:ff
On a Windows ^® 2000 or newer system, type the following at the command prompt:
arp -s a.b.c.d aa-bb-cc-dd-ee-ff
(where a.b.c.d is the IPv4 address you want to temporarily assign to the IOLAN, and
aa:bb:cc:dd:ee:ff is the Ethernet (MAC) address of IOLAN (found on the back of the unit).
- Whether you use UNIX or Windows ^ , you are now ready to ping to the IOLAN. Here is a UNIX example of the sequence to use:
arp -s 192.168.209.8 00:80:d4:00:33:4e
ping 192.168.209.8
From the ping command issued in step 2, the IOLAN will pickup and use the IP address entered into the ARP table in step 1. You are now ready to configure the IOLAN. See Chapter Configuration Methods for information on the different IOLAN configuration methods.
For an IPv6 Network
The IOLAN has a factory default link local IPv6 address based upon its MAC Address. For example, the link local address is:
IOLAN MAC Address: 00-80-D4-AB-CD-EF
Link Local Address: fe80::0280:D4ff:feAB:CDEF
By default, the IOLAN will listen for IPV6 router advertisements to obtain additional IPV6 addresses. No configuration is required, however, you can manually configure IPV6 addresses and network settings; see Chapter Network Settings for more information on IPv6 configuration options.
You are now ready to configure the IOLAN. See Chapter Configuration Methods for information on the different IOLAN configuration methods.
Setting Up the Serial Port(s)
The DeviceManager and WebManager have the following serial port profiles that will simplify serial port setup:

text_image
Choose Serial Port Profile Profile Selection Console Management TruePort TCP Sockets UDP Sockets Terminal Printer Serial Tunneling Virtual Modem Control Signal I/O Modbus Gateway Power Management Remote Access (PPP) Remote Access (SLIP) Custom Application The Terminal profile allows network access from a terminal connected to the IOLAN's serial port. This profile is used to access pre-defined hosts on the network from the terminal. Terminal IOLAN Connect Network UNIX/Linux System OK Cancel Details- Console Management—The Console Management profile configures a serial port to provide network access to a console or administrative port. This profile sets up a serial port to support a TCP socket that listens for a Telnet or SSH connection from the network.
- TruePort—The TruePort profile configures a serial port to connect network servers or workstations running the TruePort software to a serial device as a virtual COM port. This profile is ideal for connecting multiple serial ports to a network system or server.
- TCP Sockets—The TCP Sockets profile configures a serial port to allow a serial device to communicate over a TCP network. The TCP connection can be configured to be initiated from the network, a serial device connected to the serial port, or both. This is sometimes referred to as a raw connection or a TCP raw connection.
- UDP Sockets—The UDP Sockets profile configures a serial port to allow communication between the network and serial devices connected to the IOLAN using the UDP protocol.
- Terminal—The Terminal profile configures a serial port to allow network access from a terminal connected to the IOLAN's serial port. This profile is used to access predefined hosts on the network from the terminal.
- Printer—The Printer profile configures a serial port to support a serial printer that can be accessed by the network.
-
Serial Tunneling—The Serial Tunneling profile configures a serial port to establish a virtual link over the network to a serial port on another IOLAN. Both IOLAN serial ports must be configured for Serial Tunneling (typically one serial port is configured as a Tunnel Server and the other serial port as a Tunnel Client).
-
Virtual Modem—The Virtual Modem (Vmodem) profile configures a serial port to simulate a modem. When the serial device connected to the IOLAN initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN configured with a Virtual Modem serial port or to a host running a TCP application.
- Control Signal I/O—The Control Signal I/O profile enables the use of the EIA-232 serial port signal pins to be used as assigned Digital Inputs or Digital Outputs.
- Modbus Gateway—The Modbus Gateway profile configures a serial port to act as a Modbus Master Gateway or a Modbus Slave Gateway.
- Power Management—The Power Management profile configures a serial port to communicate with a Remote Power Switch's (RPS) administration port. This allows network access to the RPS and permits access to statistics and control of the RPS's power plugs.
- Remote Access (PPP)—The Remote Access (PPP) profile configures a serial port to allow a remote user to establish a PPP connection to the IOLAN's serial port. This is typically used with a modem for dial-in or dial-out access to the network.
- Remote Access (SLIP)—The Remote Access (SLIP) profile configures a serial port to allow a remote user to establish a SLIP connection to the IOLAN's serial port. This is typically used with a modem for dial-in or dial-out access to the network.
- Custom Application/Plugin—The Custom Application/Plugin profile configures a serial port to run a custom application or IOLAN plugin. After you download the custom application files and specify the application name and any parameters you want to pass to it, the IOLAN will execute the application when the serial port is started.
Each serial port profile contains all the parameters that are required to completely configure the serial port scenario represented by the profile.
To select a serial port profile in the DeviceManager, connect through the DeviceManager to the IOLAN you are configuring and select Serial, Serial Ports in the navigation pane. Highlight the serial port you want to configure and then click Edit.

5Using DeviceManager and WebManager
Introduction
The DeviceManager and WebManager IOLAN managers have been designed to be very similar to use. DeviceManager is a Windows ^® -based application and WebManager is a browser-based application. Both options use the IOLAN's IP address to access the IOLAN; the DeviceManager can be used to assign an IP address to a new IOLAN and the WebManager requires that the IOLAN already have an IP address before it can be used to configure the IOLAN.
When using WebManager, you are required to click the Apply button each time you make a change to a configuration window/tab. In DeviceManager, you must download your configuration changes to the IOLAN either periodically or after you are done with the configuration changes. From both managers you must reboot the IOLAN in order for you configuration changes to take effect.
Navigating DeviceManager/WebManager
The DeviceManager and WebManager have very similar navigation methods. The left-hand side of the manager is the navigation tree and the center is the configuration area. The DeviceManager has menu and quick access buttons, whereas the WebManager has system information and some navigation options on the far right-hand side.
DeviceManager
The DeviceManager has a navigation tree that you can use to access the available Configuration and Statistics pages in the display area. When you select an option in the navigation tree, you can often navigate the tabs or buttons in the display area to access the various configuration and statistics options. See Using DeviceManager for more information on how to navigate the pages of DeviceManager.

- Type a valid temporary IP address into the address field or, in version 3.2 or higher, enable the Have the IOLAN automatically get a temporary IP address. If you enable the temporary IP address, the IOLAN will enable DHCP/BOOTP on your IOLAN and attempt to get an IP address from the DHCP/BOOTP server (this will permanently enable DHCP/BOOTP in your IOLAN's configuration, until you change it). If your network does not have a DHCP/BOOTP server, the IOLAN will temporarily assign an IP address in the range of 169.254.0.1-169.254.255.255 (this IP address is only assigned for the duration of the DeviceManager/IOLAN connection).
- Click the Assign IP button.
- Double-click the IOLAN in the IOLAN List. If this is the first time you are accessing the IOLAN, type in the factory default admin password, superuser, and click OK. The DeviceManager will display a window indicating that it is trying to authenticate and connect you on the IOLAN.
- If the authentication and connection are successful, the Server Info window is displayed. You are now ready to configure the IOLAN. If authentication was unsuccessful, try to connect to the IOLAN again; you probably mistyped the password for the admin user.
For more information about managing the IOLAN, see Configuration Files.

Configuration Files
Creating a New IOLAN Configuration in DeviceManager
In DeviceManager, when you select File, New, the New Configuration window is displayed.

Select the IOLAN model for which you want to create a new configuration file. Any configuration file created in this manner can only be save locally. To download a created configuration file, you must first connect to the IOLAN, import the created configuration file into DeviceManager (this is not available in WebManager), and then download the configuration file to the IOLAN and reboot it. Opening an Existing Configuration File
If you select the File, Open, a browse window is opened so you can select the configuration file you want to edit. IOLAN configuration files saved in the DeviceManager can be in the IOLAN-native binary format (.dme) or as a text file (.txt), which can be edited with a text editor. Either configuration version can be imported into the DeviceManager. IOLAN configuration files saved from WebManager can also be opened into DeviceManager.
Importing an Existing Configuration File
If you have a local, saved configuration file that you want to download to the IOLAN, you must first connect to the IOLAN that you want to download the configuration file to. Once you have successfully logged into the IOLAN, in DeviceManager select Tools, Import Configuration from a File and in WebManager select Administration, Restore/Backup. You need to download the file in DeviceManager and in both managers you need to reboot the IOLAN.
Managing the IOLAN
Most of the management tasks, such as setting the time/date, downloading keys/certificates, downloading firmware, downloading custom files, resetting serial ports, etc., are found under the Tools menu option in the DeviceManager and under Administration in WebManager.

Mode Specify the mode of operation for the IOLAN's WLAN operation.
Client: The IOLAN's wireless interface is used to connect to an AP (Access Point).
Soft-AP: The IOLAN's wireless interface acts as an AP (Access Point) allowing wireless clients to connect.
Disabled: The IOLAN's wireless capabilities are disabled. When disabled, the external WPS button will have no effect on the mode of the IOLAN.
Default: Client
Radio Band The IOLAN can operate over 2.4GHz or 5GHz. To support connections to one or the other bands use 2.4+5.
Values: 2.4, 5, 2.4+5
Default: 2.4+5 (dual-band)
WPS Enabled (in client mode) By default WPS (Wireless Protected Setup) mode is enabled to allow the IOLAN to easily connect to any routers/Access Points that are in supported WPS mode. In WPS mode, the IOLAN will scan (120 seconds) all networks to find the closest AP that is currently in WPS mode. The IOLAN will exchange credentials with that AP and then create an internal wireless profile (association) and will then exit WPS mode.
Values: on or off
Default: on
WPS Enabled (in Soft-AP mode) The WPS button can be used in Soft-AP mode to facilitate the connection of wireless clients.
Passive Scan Only In passive scan mode the IOLAN will scan all channels and listen for beacons being sent by the AP's on these channels. In active scan mode, the IOLAN actively seeks out AP's by sending out probes on these channels to accelerate their discovery. Active scan mode can be disabled by setting the Passive Scanning Only Mode to On.
Values: on or off
Default: off
Roaming Enabled This setting allows you to roam (reconnect) to a different wireless router/AP (with the same SSID) if there is a significant difference in the signal strength.
Values: on or off
Default: on
Roaming Decision When roaming, the IOLAN will be constantly scanning in the background to determine if there is a better AP to connect to within the ESSID network. Since this background scanning can have an effect on performance, it will normally do slow scans when the signal is strong and faster scans when the signal is weaker.
Values: Balanced, Optimize Bandwidth, Optimize Distance
Default: Balanced
Out of Range Scan Specify the out of range scan interval for fast roaming scans.
Values: 0-65535 seconds
Default: 30 seconds

Route List
Overview
Entering routes in the routing list enables the identification of gateways to be used for accessing specific hosts or external networks from the IOLAN's local network.
Functionality
There are three types of routes:
- Default—A route that provides general access beyond your local network.
- Host—A route defined for accessing a specific host external to your local network.
• Network—A route defined for accessing a specific network external to your local network.
You can specify up to 20 routes on desktop IOLAN models; you can specify up to 49 routes on rack mount and medical unit IOLAN models.
Two types or gateways (method of accessing specific hosts or external networks) can be configured:
- Host—Specify a specify host that will provide access to the route destination.
- Interface—Specify the IPv6 tunnel, Remote Access (PPP)-defined serial port, or Remote Access (SLIP)-defined serial port that will provide access to the route destination.

RIP
Overview
The Routing Information Protocol (RIP) is a routing protocol used with almost every TCP/IP implementation. Its function is to pass routing information from a router or gateway to a neighboring router(s) or gateway(s). RIP messages contain information about destinations which can be reached and the number of hops which are required. The hop-count is the basic metric of RIP and so RIP is referred to as a “distance vector protocol”. RIP messages are carried in UDP datagrams.
Functionality
You can configure RIP to selectively advertise networks remotely connected via a SLIP/PPP link on the Ethernet connection, and pass RIP routing information to remotely connected clients. As this can be undesirable in some environments, this behavior can be configured and is defaulted to the non-routing behavior.
Transmission and reception of Routing Information Protocol (RIP) packets over PPP and SLIP connections can be configured on a per user basis or on a per serial port basis.
The Routing parameter can be configured:
- On the Advanced tab for Remote Access (PPP) and Remote Access (SLIP) profiles configured for a serial port to determine the exchange of RIP packets between the IOLAN and remotely connected users connected from the serial side.
- On the Services tab for each local user to determine the exchange of RIP packets between the IOLAN and remotely connected users connected from the serial side.
- By the RADIUS server for users authenticated by RADIUS, the RADIUS-defined Framed-Routing parameter determines the exchange of RIP packets.
There are four options for setting the Routing parameters:
- None—Routing information is not exchanged across the link. This is the default setting for a line and a locally defined user.
- Send—Routing information is only transmitted to the remote user.
- Listen—Routing information is only received from the remote user.
- Send and Listen—Routing information is transmitted to and received from the remote user.
The local User Routing parameter or RADIUS Framed-Routing parameter, if set, override the serial port Routing parameter for a connection.

Dynamic DNS
Overview
Dynamic DNS Service providers enable users to access a server connected to the internet that has been assigned a dynamic IP address. The IOLAN product line has built-in support for the DynDNS.com service provider. Refer to www.DynDNS.com for information on setting up an account.
Functionality
When the IOLAN is assigned a dynamic IP address, it will inform the DynDNS.com service provider of its new IP address. Users can then use DynDNS.com as a DNS service to get the IP address of the IOLAN. In order to take advantage of this service, the following steps need to be taken.
- Create an account with DynDNS.com and configure the name your IOLAN will be known by on the internet (the Host name). For example, create a host name such as yourcompanySCS.DynDNS.org.
- Enable the Network Dynamic DNS feature and configure the IOLAN's dynamic DNS parameters to match the Host's configuration on the DynDNS.com server. Every time the IOLAN gets assigned a new IP address, it will update DynDNS.com with the new IP address.
- Users accessing the IOLAN via the internet can now access it via its fully qualified host name. For example, telnet yourcompanySCS.DynDNS.org.

Name The name of the IPv6 tunnel.
Field Format: Maximum 16 alphanumeric characters
Default: ipv6_tunnel1
Mode The method or protocol that is used to create the IPv6 tunnel.
- Manual—When enabled, the IOLAN will manually create the IPv6 tunnel to the specified Remote Host through the specified Interface.
- 6to4—When enabled, the IOLAN will broadcast to the multicast address 192.88.99.1 through the specified Interface. When the closest 6to4 router responds, it will create the IPv6 tunnel, encapsulating and decapsulating IPv6 traffic sent to and from the IOLAN.
- Teredo—When enabled, the Teredo protocol encapsulates the IPv6 packet as an IPv4 UDP message, allowing it to pass through most network address translator (NAT) boxes and create an IPv6 tunnel to the specified Remote Host (a Teredo server) through the specified Interface.
Default: Manual
Remote Host The IPv4 host that can access the IPv6 network when the Mode is Manual.
The Teredo server when the Mode is Teredo.
Default: None
Interface The interface that the IOLAN is going to use to access the Remote Host. The list is comprised of the Ethernet interface(s) and serial ports configured for the Remote Access (PPP) or Remote Access (SLIP) profiles.
Default: Ethernet 1

Introduction
You can configure up to four users in the IOLAN's local user database for all DS, SDS, and STS 1-port to 4-port desktop models, in addition to the admin user. You can configure up to 48 users in the IOLAN's local user database for all STS, SCS, and SDS rack mount models and all MDC medical unit models, in addition to the admin user. A user can even represent a device, like a barcode reader or a card swipe device, that you want to be authenticated.
When users are connecting to the IOLAN via serial ports, the user database can be used to:

text_image
Configuration Network IP Settings Advanced Serial Serial Ports Port Buffering Advanced Users- Have the user authenticated prior to establishing a connection to a network host.
- Establish a different connection type to the host specific to each user.
• Create a profile different from the Default user profile.
When users are connecting to the IOLAN from a network connection, the user database can be used to:
- Provide authentication on the IOLAN prior to establishing a serial connection via PPP or SLIP.
- Authenticate users prior to providing access to a serially attached console port (such as a Unix server or router).
Note: You do not need user accounts for users who are externally authenticated.
User Settings
Overview
The Users window allows you to add, edit, and delete users from the IOLAN.
Functionality
The Users window displays the users who have been configured. You can add users, edit existing users, or delete users from this window. You cannot delete the pre configured admin user. See Adding/Editing Users for information on the parameters available when adding or editing a user.

Overview
The General tab configures the basic user information.
Functionality
You must, minimally, provide a User Name and Level for a user.
Field Descriptions

text_image
User Settings General Services Advanced Sessons Serial Port Access User Name: Password: Confirm Password: Level: OK CancelConfigure the following parameters:
User Name The name of the user.
Restrictions: Do not use spaces.
Password The password the user will need to enter to login to the IOLAN.
Confirm Password Enter the user's password again to verify it is entered correctly.
Level The access that a user is allowed.
Data Options:
- Admin—The admin level user has total access to the IOLAN. You can create more than one admin user account but we recommend that you only have one. They can monitor and configure the IOLAN. Users configured with this level can access the unit either via serial Terminal Profile connection or via a network originated Telnet or SSH connection to the IOLAN.
- Normal—The Normal level user has limited access to the IOLAN. Limited CLI commands and Menu access are available with the ability to configure the user's own configuration settings. Users configured with this level can access the unit either via serial Terminal Profile connection or via a network originated Telnet or SSH connection to the IOLAN.
- Restricted—The Restricted level user can only access predefined sessions or access the Easy Port Access menu. Users configured with this level will be restricted to pre-defined sessions or limited CLI commands when connecting through the serial port via the Terminal Profile. The CLI commands are limited to those used for initiating a session. If connection to the IOLAN is done with Telnet or SSH from the network, the user will be presented with the Easy Port Access menu.
- Menu—The menu level user will only be able to access predefined session when connecting through a serial port with the Terminal profile or will be limited to the Easy Port Access menu when connecting from the network. The Easy Port Access allows the user to connect to the accessible line without disconnecting their initial connection to the IOLAN. Does not have any access to CLI commands.
When the admin user logs into the IOLAN, the prompt ends with a #, whereas all other users' prompts ends with a \$ or £, depending on the character set.
Default: Normal
Note: A technique for giving a serially attach user (dial-in or terminal attached), the same menus as one that is network connected is to do the following:
- Define the serial port with a Terminal Profile using telnet protocol with a direct connection to Host IP address 127.0.0.0 (local loop back).
- When the user connects to that serial port a Telnet session will be established to the IOLAN and the user will appear to have connected from the network.
Services Tab
Overview
The Services tab configures the connection parameters for a user. Any connection parameters configured in this window will override the serial port connection parameters.
Functionality
When a Terminal profile is set for the serial port and Require Login has been selected, user's accessing the IOLAN through the serial port will be authenticated. Once authentication is successful, the Service specified here is started. For example, if the Service Telnet is specified, the IOLAN will start a Telnet connection to the specified Host IP/TCP Port after the user is successfully authenticated (logs in successfully).
Within the Terminal profile, there are a number of settings that apply to possible Services. Once it is known which user is connected, and which service is to be used, then the settings from both the Terminal profile and the user are used. User parameters take precedence over serial port parameters.

Service
Used in conjunction with the Terminal Profile. After the user has successfully been authenticated, the specified service is started.
Data Options: DSPrompt, Telnet, SSH, RLogin, SLIP, PPP, TCP Raw, SSL Raw
Default: DSPrompt
Host IP
For outbound User Services such as Telnet, SSH, Rlogin, this is the target host name or IP address. If no IP address or host name is specified, the Host IP value in the Default User configuration will be used.
Default: 0.0.0.0
TCP Port
When the User Service is Telnet, this is the target port number. The default value will change based on the type of Service selected; the most common known port numbers are used as the default values.
IPv4 Address
Used for User Service PPP or SLIP, sets the IP address of the remote user. Enter the address in dot decimal notation as follows:
- n.n.n.n—(where n is a number) Enter the IP address of your choice. This IP address will then be used in preference to the Remote IP Address set for a line.
The following IP addresses have a special meaning: - 255.255.255.254—The IOLAN will use the Remote IP Address set in the PPP settings for the serial port that this user is connecting to.
- 255.255.255.255—When the User Service is PPP, the IOLAN will allow the remote machine to specify its IP address (overriding the IP address negotiation value configured in the PPP settings).
- 255.255.255.255—When the User Service is SLIP, the IOLAN will use the Remote IP Address set for the line (no negotiation).
Default: 255.255.255.254
IPv4 Subnet Mask
If the remote user is on a subnet, enter the network's subnet mask. For example, a subnet mask of 255.255.0.0.
IPv6 Interface Indentifier
Used for User Service PPP, sets the IPv6 address of the remote user. Enter the address in IPv6 format.
Field Format: The first 64 bits of the Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected format.
MTU
Used for User Service PPP or SLIP, specifies the maximum size of packets, in bytes, being transferred across the link. On noisy links it might be preferable to fragment large packets being transferred over the link, since there will a be quicker recovery from errors.
Data Options:
- PPP—MTU will be the maximum size of packets that the IOLAN will negotiate for this port. This value is negotiated between the two ends of the link.
- SLIP—MTU will be the maximum size of packets being sent by the IOLAN.
The User MTU value will override the MTU/MRU values set for a Serial Port.
Range: PPP: 64-1500 bytes, SLIP: 256-1006 bytes
Default: PPP is 1500 bytes, SLIP is 256 bytes
Routing
Determines the routing mode used for RIP packets on the PPP and SLIP interfaces. Values are:
- None—RIP packets are neither received nor sent by the IOLAN.
- Send—RIP packets can only be sent by the IOLAN.
- Listen—RIP packets can only be received by the IOLAN.
- Send and Listen—RIP packets are sent and received by the IOLAN.
Default: None
Enable VJ Compression
Used for User Service PPP or SLIP, determines whether Van Jacobsen Compression is used on the link. VJ compression is a means of reducing the standard TCP/IP header from 40 octets to approximately 5 octets. This gives a significant performance improvement, particularly when interactive applications are being used. For example, when the user is typing, a single character can be transmitted and thus have the overhead of the full TCP/IP header. VJ Compression has minimal effect on other types of links, such as ftp, where the packets are much larger. The User VJ Compression option will override the VJ Compression value set for a Serial Port.
Default: Disabled
Advanced Tab

Sessions Tab
Overview
The Sessions tab is used to configure specific connections for users who are accessing the network through the IOLAN's serial port.
Functionality
Users who have successfully logged into the IOLAN (User Service set to DSprompt) can start up to four login sessions on network hosts. These users start sessions through the EasyPort Menu option Sessions.
Multiple sessions can be run simultaneously to the same host or to different hosts. Users can switch between different sessions and also between sessions and the IOLAN using Hotkey commands (see Hotkey Prefix for a list of commands).
Users with Admin or Normal privileges can define new sessions and use them to connect to Network hosts; they can even configure them to start automatically on login to the IOLAN. Restricted and Menu users can only start sessions predefined for them in their user configuration.

(Note: IOLAN SDS W/L/G models support baud rates of 300-1843200
Default: 9600
Data Bits Specifies the number of bits in a transmitted character.
Default: 8
Note: When using IOLAN SDS G models, 5 databits is only supported with 1.5 stop bit.
Parity Specifies the type of parity being used for the data communication on the serial port. If you want to force a parity type, you can specify Mark for 1or Space for 0.
Data Options: Even, Odd, Mark, Space, None
Default: None
Stop Bits Specifies the number of stop bits that follow a byte.
Data Options: 1,1.5, 2.1.5 is only available on the 1-port and 2-port models, but not on the modem line (Serial Port 2) of the SDS1M model.
Default: 1
| Duplex | Used with a EIA-485 serial interface, specify whether the serial port is Full Duplex (communication both ways at the same time) or Half Duplex (communication in one direction at a time).Default: Full |
| TX Driver Control | Used with a EIA-485 serial interface, if your application supports RTS (Request To Send), select this option. Otherwise, select Auto.Default: Auto |
| Flow Control | Defines whether the data flow is handled by the software (Soft), hardware (Hard), Both, or None. If you are using SLIP, set to Hard only. If you are using PPP, set to either Soft or Hard (Hard is recommended). If you select Soft with PPP, you must set the ACCM parameter when you configure PPP for the Serial Port.Data Options: Soft, Hard, Both, NoneDefault: None |
| Enable RTS Toggle | Configure the Toggle RTS Feature if your application needs for RTS to be raised during character transmission.Initial delay: configure the time (in ms) between the time the RTS signal is raised and the start of character transmission. This delay only applies if this port is not running hardware flow control. If hardware flow control is used, the transmission will occur as soon as CTS is raised by the modem.Final delay: configure the time (in ms) between the time of character transmission and when RTS is dropped.Initial delay range: 0-1000 msFinal delay range: 0-1000 msDefault: Off |
| Enable Inbound Flow Control | Determines if input flow control is to be used.Default: Enabled |
| Enable Outbound Flow Control | Determines if output flow control is to be used.Default: Enabled |
| Monitor DSR Specifies whether the EIA-232 signal DSR (Data Set Ready) should be monitored. This is used with modems or any device that sends a DSR signal. When it is monitored and the IOLAN detects a DSR signal, the serial port profile is started. The Monitor DSR parameter is not available for medical unit models. If both Monitor DCD and Monitor DSR are enabled, both signals must be detected before the serial port profile is started.Default: Disabled | |
| Monitor DCD | Specifies whether the EIA-232 signal DCD (Data Carrier Detect) should be monitored. This is used with modems or any other device that sends a DCD signal. When it is monitored and the IOLAN detects a DCD signal, the serial port profile is started. If both Monitor DCD and Monitor DSR are enabled, both signals must be detected before the serial port profile is started.Default: Disabled |
| Discard Characters Received with Errors | When enabled, the IOLAN will discard characters received with a parity or framing error.Default: Disabled |
Enable Echo Suppression
This parameter applies only to EIA-485 Half Duplex mode. All characters will be echoed to the user and transmitted across the serial ports. Some EIA-485 applications require local echo to be enabled in order to monitor the loopback data to determine that line contention has occurred. If your application cannot handle loopback data, echo suppression should be enabled.
Default: Disabled
Enable Line Termination
Used with EIA-422 and EIA-485 on SDS 8-port, 16-port and 32 port rack mount IOLAN models, specifies whether or not the line is terminated; use this option when the serial port is connected to a device at the end of the serial network.
Default: Disabled
Email Alert Tab Field Descriptions
Email notification can be set at the Server and/or serial port levels. You can set unique email notifications for each serial port because the person who administers the IOLAN might not be the same person who administers the serial device(s) attached to the IOLAN port. Therefore, email notification can be sent to the proper person(s) responsible for the hardware.
The following event triggers an email notification on the Serial Port for the specified Level:
• DSR signal loss, Warning Level
• I/O alerts, Critical Level

Minimize Latency This option ensures that all application data is immediately forwarded to the serial device and that every character received from the device is immediately sent on the network. Select this option for timing-sensitive applications.
Default: Enabled
Optimize Network Throughput This option provides optimal network usage while ensuring that the application performance is not compromised. Select this option when you want to minimize overall packet count, such as when the connection is over a WAN.
Default: Disabled
| Prevent Message Fragmentation | This option detects the message, packet, or data blocking characteristics of the serial data and preserves it throughout the communication. Select this option for message-based applications or serial devices that are sensitive to inter-character delays within these messages.Default: Disabled |
| Delay Between Messages | The minimum time, in milliseconds, between messages that must pass before the data is forwarded by the IOLAN.Range: 0-65535Default: 250 ms |
| Custom Packet Forwarding | This option allows you to define the packet forwarding rules based on the packet definition or the frame definition.Default: Disabled |
| Packet Definition | When enabled, this group of parameters allows you to set a variety of packet definition options. The first criteria that is met causes the packet to be transmitted. For example, if you set aForce Transmit Timerof 1000ms and a Packet Sizeof 100bytes, whichever criteria is met first is what will cause the packet to be transmitted.Default: Enabled |
| Packet Size | The number of bytes that must be received from the serial port before the packet is transmitted to the network. A value of zero (0) ignores this parameter.Range: 0-1024 bytesDefault: 0 |
| Idle Time The amount of time, in milliseconds, that must elapse between characters before the packet is transmitted to the network. A value of zero (0) ignores this parameter.Range: 0-65535 msDefault: 0 | |
| Enable Trigger1 Character | When enabled, specifies the character that when received will define when the packet is ready for transmission. The actual transmission of the packet is based on the Trigger Forwarding Rule.Range: hexadecimal 0-FFDefault: 0 |
| Enable Trigger2 Character | When enabled, creates a sequence of characters that must be received to specify when the packet is ready for transmission (if the End Trigger1 character is not immediately followed by the End Trigger2 character, the IOLAN waits for another End Trigger1 character to start the End Trigger1/End Trigger2 character sequence). The actual transmission of the packet is based on the Trigger Forwarding Rule.Range: hexadecimal 0-FFDefault: 0 |
| Frame Definition | When enabled, this group of parameters allows you to control the frame that is transmitted by defining the start and end of frame character(s). If the internal buffer (1024 bytes) is full before the EOF character(s) are received, the packet will be transmitted and the EOF character(s) search will continue.Default: Disabled |
| SOF1 Character | When enabled, the Start of Frame character defines the first character of the frame, any character(s) received before the Start of Frame character is ignored. Range: hexadecimal 0-FF Default: 0 |
| SOF2 Character | When enabled, creates a sequence of characters that must be received to create the start of the frame (if the SOF1 character is not immediately followed by the SOF2 character, the IOLAN waits for another SOF1 character to start the SOF1/SOF2 character sequence). Range: hexadecimal 0-FF Default: 0 |
| Transmit SOF Character(s) | When enabled, the SOF1 or SOF1/SOF2 characters will be transmitted with the frame. If not enabled, the SOF1 or SOF1/SOF2 characters will be stripped from the transmission. Default: Disabled |
| EOF1 Character | Specifies the End of Frame character, which defines when the frame is ready to be transmitted. The actual transmission of the frame is based on the Trigger Forwarding Rule. Range: hexadecimal 0-FF Default: 0 |
| EOF2 Character | When enabled, creates a sequence of characters that must be received to define the end of the frame (if the EOF1 character is not immediately followed by the EOF2 character, the IOLAN waits for another EOF1 character to start the EOF1/EOF2 character sequence), which defines when the frame is ready to be transmitted. The actual transmission of the frame is based on the Trigger Forwarding Rule. Range: hexadecimal 0-FF Default: 0 |
| Trigger Forwarding Rule | Determines what is included in the Frame (based on the EOF1 or EOF1/EOF2) or Packet (based on Trigger1 or Trigger1/Trigger2). Choose one of the following options: Strip-Trigger—Strips out the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, depending on your settings. Trigger—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, depending on your settings. Trigger+1—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, depending on your settings, plus the first byte that follows the trigger. Trigger+2—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, depending on your settings, plus the next two bytes received after the trigger. Default: Trigger |
SSL/TLS Settings Tab Field Descriptions
You can create an encrypted connection using SSL/TLS for the following profiles: TruePort, TCP Sockets, Terminal (the user's Service must be set to SSL_Raw), Serial Tunneling, Virtual Modem, and Modbus. When you enable this feature, it will automatically use the global SSL/TLS settings (configured on Security, SSL/TLS), although you can configure unique SSL/TLS settings for the serial port.
When configuring SSL/TLS, the following configuration options are available:
- You can set up the IOLAN to act as an SSL/TLS client or server.
- There is an extensive selection of SSL/TLS ciphers that you can configure for your SSL/TLS connection; see Appendix B, SSL/TLS Ciphers on page 413 for a list of SSL/TLS ciphers.
Note: Some combinations of cipher groups are not available on FIPS firmware versions.
- You can enable peer certificate validation, for which you must supply the validation criteria that was used when creating the peer certificate (this is case sensitive, so keep that in mind when enabling and configuring this option).
Note: See Keys and Certificates for information about SSL/TLS support documents.

Console Management Profile
Overview
The Console Management profile provides access through the network to a console or administrative port of a server or router attached to the IOLAN's serial port. This profile configures the IOLAN's serial port to set up a TCP socket that will listen for a Telnet or SSH connection from the network.
Functionality
Use the Console Management profile when you are configuring users who need to access a serial console port from the network.

Break Handling Specifies how a break is interpreted.
Data Range:
- None—The IOLAN ignores the break key completely and it is not passed through to the host.
- Local—The IOLAN deals with the break locally. If the user is in a session, the break key has the same effect as a hot key.
- Remote—When the break key is pressed, the IOLAN translates this into a telnet break signal which it sends to the host machine.
- Break Interrupt—On some systems such as SunOS, XENIX, and AIX, a break received from the peripheral is not passed to the client properly. If the client wishes to make the break act like an interrupt key (for example, when the stty options -ignbrk and brkintr are set).
Default: None
Session Strings
Controls the sending of ASCII strings to serial devices at session start and session termination as follows;
- Send at Start - If configured, this string will be sent to the serial device on power-up of the IOLAN, or when a kill line command is issued on this serial port. If the "monitor DSR" or "monitor DCD" options are set, the string will also be sent when the monitored signal is raised.
Range: 0-127 alpha-numeric characters. Non printable ascii characters must be entered in this format <027>. The decimal numbers within the brackets must be 3 digits long (example 003 not 3).
- Send at End - If configured, this string will be sent to the serial device when the TCP session on the LAN is terminated. If multihost is configured, this string will only be send in listen mode to the serial device when all multihost connections are terminated.
Range: 0-127 alpha-numeric characters. Non printable ascii characters must be entered in this format <027>. The decimal numbers within the brackets must be 3 digits long (example 003 not 3).

TruePort Profile
Overview
TruePort is especially useful when you want to improve data security, as you can enable an SSL/TLS connection between the TruePort host port and the IOLAN. TruePort is COM Port redirector that is supplied with the IOLAN. TruePort can be installed as a client on a Workstation or Server and supports a variety of operating systems. It, in conjunction with the IOLAN, emulates a local serial port (COM port), to the application, to provide connectivity to a remote serial device over the network. The TruePort profile operates in conjunction with the TruePort software.
Functionality
TruePort is a COM port redirector utility for the IOLAN. It can be run in two modes (these modes will be set on the client software when it is configured):
- TruePort Full mode—This mode allows complete device control and operates as if the device was directly connected to the Workstation/Server's local serial port. It provides a complete COM port interface between the attached serial device and the network. All serial controls, baud rate control, etc., are sent to the IOLAN and replicated on its associated serial port.
- TruePort Lite mode—This mode provides a simple raw data interface between the application and the remote serial port. Although the port will still operate as a COM port, control signals are ignored. In this mode, the serial communications parameters must be configured on the IOLAN.
See the TruePort User's Guide for more details about the TruePort client software.

TCP Sockets Profile
Overview
The TCP Socket profile allows for a serial device to communicate over a TCP network. The TCP connection can be initiated from a host on the network and/or a serial device. This is typically used with an application on a Workstation or Server that communicates to a device using a specific TCP socket. This is often referred to as a RAW connection.
Functionality
The TCP Sockets profile permits a raw connection to be established in either direction, meaning that the connection can be initiated by either the Workstation/Server or the IOLAN.

UDP Sockets Profile
Overview
The UDP profile configures a serial port to send or receive data to/from the LAN using the UDP protocol.
Functionality
When you configure UDP, you are setting up a range of IP addresses and the port numbers that you will use to send UDP data to or receive UDP data from.
When you configure UDP for LAN to Serial, the following options are available:
- To send to a single IP address, leave the End IP Address field at its default value (0.0.0.0).
- The IP address can be auto learned if both start/end IP address are left blank/default.
If the Start IP Address field is set to 255.255.255.255 and the End IP Address is left at its default value (0.0.0.0), the IOLAN will accept UDP packets from any source address.

Serial Port 1 Settings Profile: UDP Sockets Change Profile... Name: General Advanced Hardware Email Alert Packet Forwarding UDP Socket Settings Listen for connections on UDP port: 10001 Host Range Direction Start IP Address End IP Address UDP Port HTTP Tunnel 1 Both 0.0.0.0 0.0.0.0 Auto Learn 0 None 2 Disabled 0.0.0.0 0.0.0.0 Auto Learn 0 None 3 Disabled 0.0.0.0 0.0.0.0 Auto Learn 0 None 4 Disabled 0.0.0.0 0.0.0.0 Auto Learn 0 NoneFour individual entries are provided to allow you greater flexibility to specify how data will be forwarded to/from the serial device. All four entries support the same configuration parameters. You can configure one or more of the entries as needed.
The first thing you need to configure for an entry is the "Direction" of the data flow. The following options are available;
- Disabled - UDP service not enabled.
- LAN to Serial - This setting will allow UDP data to be received from one or more hosts on the LAN and forwarded to the serial device attached to this serial port.
- Serial to LAN - This setting will allow data originating from the serial device attached to this serial port to be sent to one or more hosts on the LAN using UDP datagrams.
- Both - Allows for data to flow from the serial device to the LAN and from the LAN to the serial device.
The role of each of the configurable parameters in an entry depends on the “Direction” selected.
When the direction is "LAN to Serial" the role of the additional parameters is as follow;
- Start IP Address - This is the IP address of the host from which the UDP data will originate. If the data will originate from a number of hosts, this becomes the starting IP address of a range.
- End IP Address - If you wish to receive data only from the single host defined by "Start IP address", leave this entry as is (0.0.0.0). If you wish to accept data from a number of hosts, this address will represent the upper end of a range starting from "Start IP Address". Only data originating from this range will be forwarded to the serial port.
- UDP port - This is the UPD port from which the data will originate. There are three options for this parameter.
●Auto Learn - The first UDP message received will be used to define which UDP port we are going to accept UDP data from. Once learned, only data from this UDP port will be accepted. The data must also originate from a host which is in the IP range defined for this entry.
- Any Port - Any UDP port will be accepted as long as the data originates from a host in the IP range defined for this entry.
- Port - Only data originating from the UDP port configured here as well as originating from a host in the IP range defined for this entry will be accepted.
When the direction is "Serial to LAN" the role of the additional parameters is as follow;
- Start IP Address - This is the IP address of the host to which the serial data will be sent using UDP datagrams. If the serial data is to be sent to more than one host, this becomes the starting IP address of a range.
- End IP Address - If you wish to send serial data to a single host, leave this entry as is (0.0.0.0). If you wish to send the serial data to a number of hosts, this address will represent the upper end of a range starting from "Start IP Address".
- UDP port - This is the UPD port to which the serial data will be forwarded. For a direction of "Serial to LAN", you must specify the port to be used.
When the direction is "Both" the role of the additional parameters is as follow;
- Start IP Address - This is the IP address of the host to which the serial data will be sent using UDP datagrams. It is also the IP address of the host from which UDP data coming from the LAN will be accepted from. If the data is to be sent to or received from more than one host, this becomes the starting IP address of a range.
- End IP Address - If you wish to send serial data to a single host and only receive data from the single UDP host, leave this entry as is (0.0.0.0). If the data is to be sent to or received from more than one host, this address will represent the upper end of a range starting from "Start IP Address". Only data originating from this range will be forwarded to the serial port.
- UDP Port - This is the UPD port to which the serial data will be forwarded as well as the UPD port from which data originating on the LAN will be accepted from. For a direction of "Both", there are two valid option for the UDP Port as follows;
●Auto Learn - The first UDP message received will be used to define which port we are going to accept UDP data from. Once learned, only data from this UDP port will be accepted and serial data being forwarded to the LAN will be sent to this UDP port. Until the port is learned, data from the serial port intended to be sent to the LAN will be discarded.
- Port - Serial data being forwarded to the LAN from the serial device will sent to this UDP port. Only data originating from the UDP port configured here (as well as originating from a host in the IP range defined for this entry) will be forwarded to the serial device.
Special values for "Start IP address"
- 0.0.0.0 - This is the "auto learn IP address" value which is valid only in conjunction with the "LAN to Serial" setting. The first UDP packet received for this serial port will set the IP address from which we will accept future UDP packets to be forwarded to the serial port. For this setting, leave the "End IP Address" as 0.0.0.0.
255.255.255.255 - This selection is only valid in conjunction with the "LAN to Serial" setting. It will accept all UDP packets received for this serial port regardless of the originating IP address. For this setting, leave the "End IP Address" as 0.0.0.0.
- Subnet directed broadcast - You can use the "Start IP Address" field to enter a subnet directed broadcast address. This is done by specifying the subnet address with the host portion filled with 1s. For example, if you are on the subnet 172.16.x.x with a subnet mask of 255.255.254.0 than you would specify an IP address of 172.16.1.255 (all ones for host portion). For this setting, leave the "End IP Address" as 0.0.0.0. For any "LAN to Serial" ranges you have defined for this serial port, you must ensure that IP address of this IOLAN is not included in the range. If your IP address is within the range, you will receive the data you send via the subnet directed broadcasts as data coming in from the LAN.
An example UDP configuration is described based on the following window.

Local IP Address
The IPv4 address of the IOLAN end of the SLIP link. For routing to work you must enter an IP address in this field. Choose an address that is part of the same network or subnetwork as the remote end; for example, if the remote end is address 192.101.34.146, your local IP address can be 192.101.34.145. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly.
Remote IP Address
The IPv4 address of the remote end of the SLIP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If your user is authenticated by the IOLAN, this remote IP address will be overridden if you have set a Framed IP Address for the user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Address is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Subnet Mask The network subnet mask. For example, 255.255.0.0. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Netmask is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
MTU The Maximum Transmission Unit (MTU) parameter restricts the size of individual SLIP packets being sent by the IOLAN. Enter a value between 256 and 1006 bytes; for example, 512. The default value is 256. If your user is authenticated by the IOLAN, this MTU value will be overridden when you have set a Framed MTU value for the user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-MTU is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Default: 256
Routing Determines the routing mode (RIP, Routing Information Protocol) used on the SLIP interface as one of the following options:
• None—Disables RIP over the SLIP interface.
- Send—Sends RIP over the SLIP interface.
- Listen—Listens for RIP over the SLIP interface.
- Send and Listen—Sends RIP and listens for RIP over the SLIP interface.
This is the same function as the Framed-Routing attribute for RADIUS authenticated users.
Default: None
VJ Compression
When enabled, Van Jacobson compression is used on this link. When enabled, C-SLIP, or compressed SLIP, is used. When disabled, plain SLIP is used. C-SLIP greatly improves the performance of interactive traffic, such as Telnet or Rlogin.
If your user is authenticated by the IOLAN, this VJ compression value will be overridden if you have set a Framed Compression value for a user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Compression is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Default: Enabled

Retries: 2 Configure NAK Retries: 10 Authentication Timeout: 1 Enable Roaming Callback Challenge Interval: 0 Address/Control Compression Protocol Compression VJ Compression Magic Negotiation IP Address Negotiation Dynamic DNSConfigure the following parameters:
IPv4 Local IP Address
The IPV4 IP address of the IOLAN end of the PPP link. For routing to work, you must enter a local IP address. Choose an address that is part of the same network or subnetwork as the remote end; for example, if the remote end is address 192.101.34.146, your local IP address can be 192.101.34.145. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly.
IPv4 Remote IP Address
The IPV4 IP address of the remote end of the PPP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If you set the PPP parameter IP Address Negotiation to On, the IOLAN will ignore the remote IP address value you enter here and will allow the remote end to specify its IP address. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Address is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here. The exception to this rule is a Framed-Address value in the RADIUS file of 255.255.255.254; this value allows the IOLAN to use the remote IP address value configured here.
IPv4 Subnet Mask The network subnet mask. For example, 255.255.0.0. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Netmask is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
IPv6 Local Interface Identifier
The local IPv6 interface identifier of the IOLAN end of the PPP link. For routing to work, you must enter a local IP address. Choose an address that is part of the same network or subnetwork as the remote end. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly.
Field Format: The first 64 bits of the Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected format.
IPv6 Remote Interface Identifier
The remote IPv6 interface identifier of the remote end of the PPP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If you enable Negotiate IP Address Automatically, the IOLAN will ignore the remote IP address value you enter here and will allow the remote end to specify its IP address. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Interface-ID is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Field Format: The first 64 bits of the Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected format.
ACCM
Specifies the ACCM (Asynchronous Control Character Map) characters that should be escaped from the data stream.
Field Format: This is entered as a 32-bit hexadecimal number with each bit specifying whether or not the corresponding character should be escaped. The bits are specified as the most significant bit first and are numbered 31-0. Thus if bit 17 is set, the 17th character should be escaped, that is, 0x11 (XON). The value 000a0000 will cause the control characters 0x11 (XON) and 0x13 (XOFF) to be escaped on the link, thus allowing the use of XON/XOFF (software) flow control. If you have selected Soft Flow Control on the Serial Port, you must enter a value of at least 000a0000 for the ACCM.
Default: 00000000, which means no characters will be escaped
MRU
The Maximum Receive Unit (MRU) parameter specifies the maximum size of PPP packets that the IOLAN's port will accept. If your user is authenticated by the IOLAN, the MRU value will be overridden if you have set a MTU value for the user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-MTU is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Range: 64-1500 bytes
Default: 1500
Authentication
The type of authentication that will be done on the link. You can use PAP or CHAP (MD5-CHAP, MS-CHAPv1 and MS-CHAPv2) to authenticate a user or client on the IOLAN. When setting either PAP and CHAP, make sure the IOLAN and the PPP peer, have the same setting. For example, if the IOLAN is set to PAP, but the remote end is set to CHAP, the connection will be refused.
Data Options:
None - no authentication will be performed.
PAP—is a one time challenge of a client/device requiring that it respond with a valid username and password. A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully, the link will be terminated.
CHAP—challenges a client/device at regular intervals to validate itself with a username and a response, based on a hash of the secret (password). A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully, the link will be terminated. MD5-CHAP and Microsoft MS-CHAPv1/MS-CHAPv2 are supported. The IOLAN will attempt MS-CHAPv2 with MPPC compression, but will negotiate to the variation of CHAP, compression and encryption that the remote peer wants to use.
Default: CHAP
User
Complete this field only if you have specified PAP or CHAP (security protocols) in the Authentication field, and
- you wish to dedicate this line to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN).
When Connect is set to Dial Out or both Dial In/Dial Out are enabled, the User is the name the remote device will use to authenticate a port on this IOLAN.
The remote device will only authenticate your IOLAN's port when PAP or CHAP are operating. You can enter a maximum of sixteen alphanumeric characters; for example, tracy201. When connecting together two networks, enter a dummy user name; for example, DS_HQ.
Note If you want a reasonable level of security, the user name and password should not be similar to a user name or password used regularly to login to the IOLAN. External authentication can not be used for this user.
Field Format: You can enter a maximum of 254 alphanumeric characters.
Password
Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field and:
- you wish to dedicate this serial port to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN) Password means the following:
- When PAP is specified, this is the password the remote device will use to authenticate the port on this IOLAN.
- When CHAP is specified, this is the secret (password) known to both ends of the link upon which responses to challenges shall be based.
Field Format: You can enter a maximum of 16 alphanumeric characters.
Remote User
Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field, and
- you wish to dedicate this line to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN)
When Dial In or Dial In/Dial Out is enabled, the Remote User is the name the IOLAN will use to authenticate the port on the remote device. Your IOLAN will only authenticate the port on the remote device when PAP or CHAP are operating. When connecting together two networks, enter a dummy user name; for example, DS_SALES.
Note If you want a reasonable level of security, the user name and password should not be similar to a user name or password used regularly to login to the IOLAN. This option does not work with external authentication.
Field Format: You can enter a maximum of 254 alphanumeric characters.
Remote Password
Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field, and
- you wish to dedicate this serial port to a single remote user, and this user will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN) Remote password means the following:
- When PAP is specified, this is the password the IOLAN will use to authenticate the remote device.
- When CHAP is specified, this is the secret (password) known to both ends of the link upon which responses to challenges will be based.
Remote Password is the opposite of the parameter Password. Your IOLAN will only authenticate the remote device when PAP or CHAP is operating.
Field Format: You can enter a maximum of 16 alphanumeric characters.
Routing Determines
the routing mode (RIP, Routing Information Protocol) used on the PPP interface. This is the same function as the Framed-Routing attribute for RADIUS authenticated users.
Data Options
- None—Disables RIP over the PPP interface.
- Send—Sends RIP over the PPP interface.
- Listen—Listens for RIP over the PPP interface.
- Send and Listen—Sends RIP and listens for RIP over the PPP interface.
Default: None
Configure Req. Timeout
The maximum time, in seconds, that LCP (Link Control Protocol) will wait before it considers a configure request packet to have been lost.
Range: 1-255
Default: 3 seconds
Configure Req. Retries
The maximum number of times a configure request packet will be re-sent before the link is terminated.
Range: 0-255
Default: 10 seconds
| Terminate Req. Timeout | The maximum time, in seconds, that LCP (Link Control Protocol) will wait before it considers a terminate request packet to have been lost.Range: 1-255Default: 3 seconds |
| Terminate Req. Retries | The maximum number of times a terminate request packet will be re-sent before the link is terminated.Range: 0-255Default: 2 seconds |
| Configure NAK Retries | The maximum number of times a configure NAK packet will be re-sent before the link is terminated.Range: 0-255Default: 10 seconds |
| Authentication Timeout | The timeout, in minutes, during which successful PAP or CHAP authentication must take place (when PAP or CHAP are specified). If the timer expires before the remote end has been authenticated successfully, the link will be terminated.Range: 1-255Default: 1 minute |
| Roaming Callback | A user can enter a telephone number that the IOLAN will use to callback him/her. This feature is particularly useful for a mobile user. Roaming callback can only work when the User Enable Callback parameter is enabled. Enable Roaming Callback therefore overrides (fixed) User Enable Callback. To use Enable Roaming Callback, the remote end must be a Microsoft Windows OS that supports Microsoft's Callback Control Protocol (CBCP). The user is allowed 30 seconds to enter a telephone number after which the IOLAN ends the call.Default: Disabled |
| Challenge Interval | The interval, in minutes, for which the IOLAN will issue a CHAP re-challenge to the remote end. During CHAP authentication, an initial CHAP challenge takes place, and is unrelated to CHAP re-challenges. The initial challenge takes place even if re-challenges are disabled. Some PPP client software does not work with CHAP re-challenges, so you might want to leave the parameter disabled in the IOLAN.Range: 0-255Default: 0 (zero), meaning CHAP re-challenge is disabled |
| Address/Control Compression | This determines whether compression of the PPP Address and Control fields take place on the link. For most applications this should be enabled.Default: Enabled |
| Protocol Compression | This determines whether compression of the PPP Protocol field takes place on this link.Default: Enabled |
| VJ Compression | When enabled, Van Jacobson Compression is used on this link. If your user is authenticated by the IOLAN, this VJ compression value will be overridden if you have enabled the User, Enable VJ Compression parameter. If the user is authenticated by RADIUS and the RADIUS parameter Framed-Compression is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.Default: Enabled |
| Magic Negotiation | Determines if a line is looping back. If enabled (On), random numbers are sent on the link. The random numbers should be different, unless the link loops back.Default: Disabled |
| IP Address Negotiation | Specifies whether or not IP address negotiation will take place. IP address negotiation is where the IOLAN allows the remote end to specify its IP address. When On, the IP address specified by the remote end will be used in preference to the Remote IP Address set for a Serial Port. When Off, the Remote IP Address set for the Serial Port will be used.Default: Disabled |
| Dynamic DNS Button | Launches the Dynamic DNS window when IP Address Negotiation is enabled, which can then update the DNS server with the IP address that is negotiated and accepted for the PPP session. |

Serial Tunneling Profile
Overview
The Serial Tunneling profile allows two IOLANs to be connected back-to-back over the network to establish a virtual link between two serial ports based on RFC 2217.
Functionality
The serial device that initiates the connection is the Tunnel Client and the destination is the Tunnel Server, although once the serial communication tunnel has been successfully established, communication can go both ways.

Virtual Modem Profile
Overview
Virtual Modem (Vmodem) is a feature of the IOLAN that provides a modem interface to a serial device. It will respond to AT commands and provide signals in the same way that a serially attached modem would. This feature is typically used when you are replacing dial-up modems with the IOLAN in order to provide Ethernet network connectivity.
Functionality
The serial port will behave in exactly the same fashion as it would if it were connected to a modem. Using AT commands, it can configure the modem and the issue a dial-out request (ATTD). The IOLAN will then translate the dial request into a TCP connection and data will be begin to flow in both directions. The connection can be terminated by “hanging” up the phone line.
You can also manually start a connection by typing ATD
ATD12303402304310001, without any punctuation (although you do need to add zeros where there are not three digits presents, so that the IP address is 12 digits long).

Control Signal I/O Profile
Overview
The Control Signal I/O profile is only available on IOLAN I/O models. When you configure a serial port for Control Signal I/O, you are using the DSR, DCD, CTS, DTR, and RTS serial pins for I/O channel Digital Input (DSR, DCD, and CTS) or Digital Output (DTR and RTS).
Functionality
The Control Signal I/O profile enables the use of the EIA-232 serial port pins to be used as assigned Digital Inputs or Digital Outputs.

note right of B: Dial-In Connection
Functionality
There are two options for PPP user authentication:
- You can configure a specific user/password and a specific remote user/password per a serial port.
- You can create a secrets file with multiple users and their passwords that will globally authenticate users on all serial ports.
You can use configure PPP authentication in the configuration or in the secrets file, but not both.
If you want to use a secrets file, you must download the secrets file to the IOLAN for CHAP or PAP authentication; the files must be downloaded to the IOLAN using the names chap-secrets and pap-secrets, respectively. The file can be downloaded to the IOLAN under the Custom Files option by selecting the Download Other File parameter.
In the Remote Access (PPP) profile, you must also specify the Authentication option as PAP or CHAP on the Authentication tab, but must leave the User, Password, Remote User, and Remote Password fields blank.
An example of the CHAP secrets file follows:
| # Secrets for authentication using CHAP | |||
| # client | server | secret | acceptable local IP addresses |
| barney | fred | flintstone1234567890 | 192.168.43.1 |

| IPv4 Local IP Address | The IPV4 IP address of the IOLAN end of the PPP link. For routing to work, you must enter a local IP address. Choose an address that is part of the same network or subnetwork as the remote end; for example, if the remote end is address 192.101.34.146, your local IP address can be 192.101.34.145. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly. |
| IPv4 Remote IP Address | The IPV4 IP address of the remote end of the PPP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If you set the PPP parameter IP Address Negotiation to On, the IOLAN will ignore the remote IP address value you enter here and will allow the remote end to specify its IP address. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Addressis set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here. The exception to this rule is a Framed-Addressvalue in the RADIUS file of 255.255.255.254; this value allows the IOLAN to use the remote IP address value configured here. |
| IPv4 Subnet Mask | The network subnet mask. For example, 255.255.0.0. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Netmaskis set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here. |
| Negotiate IP Address Automatically | Specifies whether or not IP address negotiation will take place. IP address negotiation is where the IOLAN allows the remote end to specify its IP address. When On, the IP address specified by the remote end will be used in preference to the Remote IP Addressset for a Serial Port. When Off, the Remote IP Addressset for the Serial Portwill be used.Default: Disabled |
| Dynamic DNS Button | Launches the Dynamic DNS window when IP Address Negotiation is enabled, which can then update the DNS server with the IP address that is negotiated and accepted for the PPP session. |
IPv6 Local Interface Identifier
The local IPv6 interface identifier of the IOLAN end of the PPP link. For routing to work, you must enter a local IP address. Choose an address that is part of the same network or subnetwork as the remote end. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly.
Field Format: The first 64 bits of the Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected format.
IPv6 Remote Interface Identifier
The remote IPv6 interface identifier of the remote end of the PPP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If you enable Negotiate IP Address Automatically, the IOLAN will ignore the remote IP address value you enter here and will allow the remote end to specify its IP address. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Interface-ID is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Field Format: The first 64 bits of the Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected format.
IPv6 Global Network Prefix
You can optionally specify an IPv6 global network prefix that the IOLAN will advertise to the device at the other end of the PPP link.

General Authentication Advanced Hardware Email Alert Packet Forwarding PPP Authentication Settings Authentication: CHAP User: Password: Remote User: Remote Password: Authentication Timeout: 1 seconds CHAP Challenge Interval: 0 minutes Enable Roaming CallbackConfigure the following parameters:
Authentication
The type of authentication that will be done on the link. You can use PAP or CHAP (MD5-CHAP, MS-CHAPv1 and MS-CHAPv2) to authenticate a user or client on the IOLAN. When setting either PAP and CHAP, make sure the IOLAN and the PPP peer, have the same setting. For example, if the IOLAN is set to PAP, but the remote end is set to CHAP, the connection will be refused.
Data Options:
None - no authentication will be performed.
PAP—is a one time challenge of a client/device requiring that it respond with a valid username and password. A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully, the link will be terminated.
CHAP—challenges a client/device at regular intervals to validate itself with a username and a response, based on a hash of the secret (password). A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully, the link will be terminated. MD5-CHAP and Microsoft MS-CHAPv1/MS-CHAPv2 are supported. The IOLAN will attempt MS-CHAPv2 with MPPC compression, but will negotiate to the variation of CHAP, compression and encryption that the remote peer wants to use.
Default: CHAP
User
Complete this field only if you have specified PAP or CHAP (security protocols) in the Authentication field, and
- you wish to dedicate this line to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN).
When Connect is set to Dial Out or both Dial In/Dial Out are enabled, the User is the name the remote device will use to authenticate a port on this IOLAN. The remote device will only authenticate your IOLAN's port when PAP or CHAP are operating. You can enter a maximum of sixteen alphanumeric characters; for example, tracy201. When connecting together two networks, enter a dummy user name; for example, DS_HQ.
Note If you want a reasonable level of security, the user name and password should not be similar to a user name or password used regularly to login to the IOLAN. External authentication can not be used for this user.
Field Format: You can enter a maximum of 254 alphanumeric characters.
Password
Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field and:
- you wish to dedicate this serial port to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN)
Password means the following: - When PAP is specified, this is the password the remote device will use to authenticate the port on this IOLAN.
- When CHAP is specified, this is the secret (password) known to both ends of the link upon which responses to challenges shall be based.
Field Format: You can enter a maximum of 16 alphanumeric characters.
Remote User
Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field, and
- you wish to dedicate this line to a single remote user, who will be authenticated by the IOLAN, or
- you are using the IOLAN as a router (back-to-back with another IOLAN)
When Dial In or Dial In/Dial Out is enabled, the Remote User is the name the IOLAN will use to authenticate the port on the remote device. Your IOLAN will only authenticate the port on the remote device when PAP or CHAP are operating. When connecting together two networks, enter a dummy user name; for example, DS_SALES.
Note If you want a reasonable level of security, the user name and password should not be similar to a user name or password used regularly to login to the IOLAN. This option does not work with external authentication.
Field Format: You can enter a maximum of 254 alphanumeric characters.
| Remote Password | Complete this field only if you have specified PAP or CHAP (security protocols) in the Security field, andyou wish to dedicate this serial port to a single remote user, and this user will be authenticated by the IOLAN, oryou are using the IOLAN as a router (back-to-back with another IOLAN)Remote password means the following:When PAP is specified, this is the password the IOLAN will use to authenticate the remote device.When CHAP is specified, this is the secret (password) known to both ends of the link upon which responses to challenges will be based.Remote Password is the opposite of the parameter Password. Your IOLAN will only authenticate the remote device when PAP or CHAP is operating.Field Format: You can enter a maximum of 16 alphanumeric characters. |
| Authentication Timeout | The timeout, in minutes, during which successful PAP or CHAP authentication must take place (when PAP or CHAP are specified). If the timer expires before the remote end has been authenticated successfully, the link will be terminated.Range: 1-255Default: 1 minute |
| CHAP Challenge Interval | The interval, in minutes, for which the IOLAN will issue a CHAP re-challenge to the remote end. During CHAP authentication, an initial CHAP challenge takes place, and is unrelated to CHAP re-challenges. The initial challenge takes place even if re-challenges are disabled. Some PPP client software does not work with CHAP re-challenges, so you might want to leave the parameter disabled in the IOLAN.Range: 0-255Default: 0 (zero), meaning CHAP re-challenge is disabled |
| Enable Roaming Callback | A user can enter a telephone number that the IOLAN will use to callback him/her. This feature is particularly useful for a mobile user. Roaming callback can only work when the User Enable Callback parameter is enabled. Enable Roaming Callback therefore overrides (fixed) User Enable Callback. To use Enable Roaming Callback, the remote end must be a Microsoft Windows OS that supports Microsoft’s Callback Control Protocol (CBCP). The user is allowed 30 seconds to enter a telephone number after which the IOLAN ends the call.Default: Disabled |

Routing Determines the routing mode (RIP, Routing Information Protocol) used on the
PPP interface. This is the same function as the Framed-Routing attribute for RADIUS authenticated users.
Data Options
• None—Disables RIP over the PPP interface.
- Send—Sends RIP over the PPP interface.
- Listen—Listens for RIP over the PPP interface.
- Send and Listen—Sends RIP and listens for RIP over the PPP interface.
Default: None
ACCM
Specifies the ACCM (Asynchronous Control Character Map) characters that should be escaped from the data stream.
Field Format: This is entered as a 32-bit hexadecimal number with each bit specifying whether or not the corresponding character should be escaped. The bits are specified as the most significant bit first and are numbered 31-0. Thus if bit 17 is set, the 17th character should be escaped, that is, 0x11 (XON). The value 000a0000 will cause the control characters 0x11 (XON) and 0x13 (XOFF) to be escaped on the link, thus allowing the use of XON/XOFF (software) flow control. If you have selected Soft Flow Control on the Serial Port, you must enter a value of at least 000a0000 for the ACCM.
Default: 00000000, which means no characters will be escaped
MRU
The Maximum Receive Unit (MRU) parameter specifies the maximum size of PPP packets that the IOLAN's port will accept. If your user is authenticated by the IOLAN, the MRU value will be overridden if you have set a MTU value for the user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-MTU is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.

Default: 10 ms
Remote Access (SLIP) Profile
Overview
The Remote Access (SLIP) profile configures a serial port to allow a remote user to establish a SLIP connection to the IOLAN's serial port. This is typically used with a modem for dial-in or dial-out access to the network.

Local IP Address
The IPv4 address of the IOLAN end of the SLIP link. For routing to work you must enter an IP address in this field. Choose an address that is part of the same network or subnetwork as the remote end; for example, if the remote end is address 192.101.34.146, your local IP address can be 192.101.34.145. Do not use the IOLAN's (main) IP address in this field; if you do so, routing will not take place correctly.
Remote IP Address
The IPv4 address of the remote end of the SLIP link. Choose an address that is part of the same network or subnetwork as the IOLAN. If your user is authenticated by the IOLAN, this remote IP address will be overridden if you have set a Framed IP Address for the user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Address is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Subnet Mask The network subnet mask. For example, 255.255.0.0. If your user is authenticated by RADIUS and the RADIUS parameter Framed-Netmask is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.

If your user is authenticated by RADIUS and the RADIUS parameter Framed-MTU is set in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the value configured here.
Default: 256
Routing Determines the routing mode (RIP, Routing Information Protocol) used on the SLIP interface as one of the following options:
• None—Disables RIP over the SLIP interface.
- Send—Sends RIP over the SLIP interface.
- Listen—Listens for RIP over the SLIP interface.
- Send and Listen—Sends RIP and listens for RIP over the SLIP interface.
This is the same function as the Framed-Routing attribute for RADIUS authenticated users.
Default: None
VJ Compression When enabled, Van Jacobson compression is used on this link. When enabled, C-SLIP, or compressed SLIP, is used. When disabled, plain SLIP is used. C-SLIP greatly improves the performance of interactive traffic, such as Telnet or Rlogin.
If your user is authenticated by the IOLAN, this VJ compression value will be overridden if you have set a Framed Compression value for a user. If your user is authenticated by RADIUS and the RADIUS parameter Framed-

Custom Application Profile
Overview
The Custom App/Plugin profile is used in conjunction with custom applications created for the IOLAN by using the Perle SDK. See the SDK Programmer's Guide (the SDK and guide are accessible via a request form located on the Perle website at
www.perle.com/supportfiles/SDK_Request.shtml) for information about the functions that are supported.
Functionality
You must download the program and any ancillary files to the IOLAN and set the serial port to the Custom App/Plugin profile to actually run a custom application. You must also specify the program executable and any parameters you want to pass to the program in the Command Line field. The custom application is automatically run when the serial port is started.

Port Buffering
Overview
The Port Buffering feature allows data activity on the IOLAN's serial ports to be held in memory for viewing at a later stage without affecting the normal operation of the serial ports.
Note: Port Buffering is only supported on serial port(s) configured for the Console Management profile.
Functionality
Port Buffering is required by system administrators to capture important information from devices attached to the IOLAN. If a device (such as a Router) has a problem and sends a warning message out of its console port while no one is connected, the warning can be lost. With Port Buffering enabled, the messages will be captured in memory or in a file and can be viewed later to aid administrators in diagnosing and fixing problems.
Local Port Buffering
Port buffer information for the serial port can be viewed after successful connection to a device on a serial port. The user can toggle between communicating to the device on the serial port and viewing the port buffer data for that device by entering a the View Buffer String (default \~view). Local port buffering is limited to 256Kb and will be flushed after the IOLAN reboots.
To view the local port buffer for a particular serial port, you must:
- Connect to the device on that serial port by Telnet or SSH (the serial port(s) must be set to the Console Management profile to support this type of connection).
- Once you have established a connection to a device, you can enter the View Buffer String at any time to switch the display to the content of the port buffer for that particular serial port.
- To return to communicating to the device, press the ESC key and the communication session will continue from where you left off.
To navigate through the port buffer data, the following chart illustrates the keyboard keys or “hot keys” that can be used to view the port buffer data. Press the ESC key and to continue to communicate with the device on that particular serial port.
| Keyboard Buttons Hot Keys Direction | |
| Page UpB Up | |
| Page DownF Down | |
| HomeT Top of the buffer data (oldest data) | |
| EndE Bottom of the buffer (latest data) | |
| ESC Exit viewing port buffer data. |
Remote Port Buffers
The Remote Port Buffering feature allows data received from serial ports on the IOLAN to be sent to a remote server on the LAN. The remote server, supporting Network File System (NFS), allows administrators to capture and analyze data and messages from the serial device connected to the IOLAN serial port.
Remote Port Buffering data can be encrypted or raw and/or time stamped. The data is transmitted to an NFS server where a unique remote file is created for each serial port using the configured serial port Name for the file name. If the serial port Name parameter is left blank, the IOLAN will create unique files using the IOLAN's Ethernet MAC address and serial port number. It is recommended that a unique NFS directory and serial port Name be configured if multiple IOLANs use the same NFS host for Remote Port Buffering.
The filenames will be created on the NFS host with a .ENC extension to indicate data encrypted files or .DAT for unencrypted files. If the data is encrypted, the Decoder utility application must be run on the NFS server to convert the encrypted data to a readable file for administrators to analyze. The Decoder Utility can be found on your installation CDROM or on the Perle website (www.perle.com).
The data that is sent to the remote buffer file is appended to the end of the file (even through IOLAN reboots), so you will want to create a size limit on the file on your remote NFS host, to keep the buffer file size from becoming too large for your system.

- All data from previous connections on that serial port has drained
• There are no other connections - Up to a 1 second interconnection poll timer has expired
Enabling this feature automatically enables a TCP keepalive mechanism which is used to detect when a session has abnormally terminated. The keepalive is sent after 3 minutes of network connection idle time.
Applications using this feature need to be aware that there can be some considerable delay between a network disconnection and the port being available for the next connection attempt, allowing any data sent on prior connections to be transmitted out of the serial port. Application network retry logic needs to accommodate this feature.

Modems Tab
Overview
You need to configure a modem if there is a modem connected to the IOLAN. If your IOLAN model contains an internal modem or a PCI slot (SCS models) for a modem card, a permanent modem string called internal_modem or IOLAN modem, respectively, exists permanently in your configuration.
Functionality
Modems are usually configured for PPP/SLIP dial in/out connections, although some modems do support raw data communication. When you click on the Modems tab, you will see the following:

TruePort Baud Rate Tab
Overview
The TruePort utility acts as a COM port redirector that allows applications to talk to serial devices across a network as though the serial devices were directly attached to the server. For IOLAN I/O models, you can also monitor and control I/O through the TruePort client.
Functionality
Since some older applications may not support the higher baud rates that the IOLAN is capable of achieving, the baud rate can be mapped to a different value on the IOLAN. Through TruePort, you can map the baud rate of the host COM port to a higher baud rate for the serial line that connects the serial device and the IOLAN. See TruePort for more information about the TruePort utility.

9Configuring Security
Introduction
The Security group includes the following configuration options:
- Authentication—When a serial port is configured for the Console Management or TCP Sockets profile, the user can be authenticated either locally in the IOLAN user profile or externally. This option configures the external authentication server. See Authentication for more information.
- SSH—This configuration window configures the SSH server in the IOLAN. See SSH for more information.
- SSL/TLS—This configuration window configures global SSL/TLS settings, which can be overridden on the serial port level. See SSL/TLS for more information.

text_image
Security Authentication SSH SSL/TLS VPN HTTP Tunnel Services Clustering Option Card System- VPN—This configuration window configures the Virtual Personal Network (VPN) IPsec and L2TP/IPsec tunnel parameters. See VPN for more information.
- HTTP Tunnel—This configuration window configures the Http Tunneling parameters. See HTTP Tunneling for more information.
- Services—This configuration window is used to enable/disabled client and daemon services that run in the IOLAN. See Services for more information.
Authentication
Authentication can be handled by the IOLAN or through an external authentication server.
Authentication is different from authorization, which can restrict a user's access to the network (although this can be done through the concept of creating sessions for a user, see Sessions Tab for more information). Authentication ensures that the user is defined within the authentication database—with the exception of using the Guest authentication option under Local Authentication, which can accept any user ID as long as the user knows the configured password.
For external authentication, the IOLAN supports RADIUS, Kerberos, LDAP/Microsoft Active Directory, TACACS+, SecurID, and NIS. You can specify a primary authentication method and a secondary authentication method. If the primary authentication method fails (cannot connect to the server or authentication fails), the secondary authentication method is tried (unless you enable the Only Use as backup option, in which case the secondary authentication method will be tried only when the IOLAN cannot communicate with the primary authentication host). This allows you to specify two different authentication methods. If you do specify two different authentication methods, the user will be prompted for his/her username once, but will be prompted for a password for each authentication method tried. For example, user Alfred's user ID is maintained in the secondary authentication database, therefore, he will be prompted for his password twice, because he is not in the primary authentication database. Unlike the other external authentication methods, RADIUS and TACACS+ can also send back Serial Port and User parameters that are used for the duration of the
connection. Therefore, any parameters configured by RADIUS or TACACS+ will override the same parameters configured in the IOLAN. See Appendix A, RADIUS and TACACS+ for more information.
Authentication
In the Authentication window, you can select up to two methods of authentication made up of external authentication options and/or the local user database.

text_image
Authentication Primary Authentication Method: LDAP/Active Directory Local RADIUS Kerberos LDAP/Active Directory TACACS+ SecurD LDAP Settings... Secondary Authentication Method: None None Local RADIUS Kerberos LDAP/Active Directory TACACS+ Only use as backup ✓ Only authenticate admin user in the local user databaseConfigure the following parameters:
| Primary Authentication Method | The first authentication method that the IOLAN attempts. Data Options: Local, RADIUS, Kerberos, LDAP/Microsoft Active directory, TACACS+, SecurID, NIS Default: Local |
| Secondary Authentication Method | If the Primary Authentication Method fails, the next authentication method that the IOLAN attempts. You can choose to use authentication methods in combination. For example, you can specify the Primary Authentication Method as Local and the Secondary Authentication Method as RADIUS. Therefore, some users can be defined in the IOLAN (Local) others in RADIUS. Data Options: None, Local, RADIUS, Kerberos, LDAP/Microsoft Active Directory, TACACS+, SecurID, NIS Default: None |
Settings Button Click this button to configure the authentication method.
Only use as backup The secondary authentication method will be tried only when the IOLAN cannot communicate with the primary authentication host.
Default: Disabled
Only authenticate admin user in the local database When enabled, the IOLAN will only authenticate the admin user in the local user database, regardless of any external authentication methods configured. When disabled, a user called admin must exist when only external authentication methods are configured, or you will not be able to access the IOLAN as the admin user, except through the console port. Default: Enabled
Local
Overview
When Local authentication is selected, the user must either be configured in the IOLAN's User List or you must enable Guest users.

LDAP/Microsoft Active Directory
Overview
LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying directory services running over TCP/IP. It is also used as a method of authenticating users. Microsoft Active Directory is an LDAP like directory service. It can be used for authenticating users in a similar fashion to LDAP. In this manual, the use of LDAP is synonymous with Microsoft Active Directory.
The following parameter need to be configured to use this feature.
Field Descriptions

text_image
LDAP/Active Directory Settings Host Name: 1 Port: 388 Eases: User Attribute: ○ OpenLDAP (uc) ○ Microsoft Active Directory (SAMAccountName) ○ Other: □ Encrypt Passwords Using MDS Digest □ Authenticate IQLIN With LDAP Server Name: □ Append Base To Name Password: Binary: □ Enable TLS TLS Plus: 638 OK CancelHost Name The name or IP address of the LDAP/Microsoft Active Directory host. If you use a host name, that host must either have been defined in the IOLAN's Host Table before the last reboot or be resolved by DNS. If you are using TLS, you must enter the same string you used to create the LDAP certificate that resides on your LDAP/Microsoft Active Directory server.
Port The port that the LDAP/Microsoft Active Directory host listens to for authentication requests.
Default: 389
Base The domain component (dc) that is the starting point for the search for user authentication. You can enter up to 128 characters for the base.
User Attribute
This defines the name of the attribute used to communicate the user name to the server.
Options:
- OpenLDAP(uid)—Chose this option if you are using an OpenLDAP server. The user attribute on this server is “uid”.
- Microsoft Active Directory(sAMAccountName)—Chose this option if your LDAP server is a Microsoft Active Directory server. The user attribute on this server is “sAMAccountName”.
- Other—If you are running something other than a OpenLDAP or Microsoft Active Directory server, you will have to find out from your system administrator what the user attribute is and enter it in this field.
Default: OpenLDAP(uid)
Encrypt Passwords Using MD5 digest
Checking this parameter will cause the IOLAN to encrypt the password using MD5 digest before sending it to server. If this option is not checked, the password is sent to the server in the clear.
Default: Disabled
Authenticate IOLAN with LDAP server
This option will cause the Terminal Server to authenticate with the LDAP server before the user authentication takes place. The user name/password to use for this authentication is configured below.
Default: Disabled
Name The user name associated with the IOLAN
Append Base to Name
When checked, this causes the domain component configured in the “base” parameter to be appended to the user name. This allows for a fully qualified name to be used when authenticating the IOLAN.
Default: Enabled but if the base parameter is not configured, it does not modify the name.
Confirm
You must enter the exact same value as the password field. Since the password is not echoed, this ensures that the field was entered correctly.
Default: Blank
Enable TLS
Enables/disables the Transport Layer Security (TLS) with the LDAP/Microsoft Active Directory host.
Default: Disabled.
TLS Port
Specify the port number that LDAP/Microsoft Active Directory will use for TLS.
Default: 636
If you are using LDAP or Microsoft Active Directory with TLS, you need to download a CA list to the IOLAN that includes the certificate authority (CA) that signed the LDAP certificate on the LDAP host by selecting Tools, Advanced, Keys and Certificates. See Keys and Certificates for more information on the LDAP certificate.

SSH
Overview
The IOLAN contains SSH Server software that you need to configure if the IOLAN is going to be accessed via SSH. If you specify more than one Authentication method and/or Cipher, the IOLAN will negotiate with the client and use the first authentication method and cipher that is compatible with both systems.
Functionality
When you are using the SSH connection protocol, keys need to be distributed to all users and the IOLAN. Below are a couple of example scenarios for key/certificate distribution.
Users Logging into the IOLAN Using SSH
This scenario applies to serial ports configured for Console Management using the SSH protocol. In the following example, users are connecting to the IOLAN via SSH from the LAN. Therefore, the following keys need to be exchanged:
- Upload the IOLAN SSH Public Key to each user's host machine who is connecting and logging into the IOLAN using SSH.
- Download the SSH Public Key from each user's host machine who is connecting and logging into the IOLAN using SSH.

Users Passing Through the IOLAN Using SSH (Dir/Sil)
This scenario applies to serial ports configured for the Terminal profile and are required to login to the IOLAN. The user's service is set to the SSH protocol, therefore, users first log into the IOLAN and then are connected to a specified host (configured for the user when User Service SSH is selected) through an SSH connection. Lynn and Tracy automatically connect to the HR Server and Dennis automatically connects to the Development Server via SSH through the IOLAN. All the SSH negotiation is being done between the IOLAN and the target servers, therefore, the following keys need to be exchanged:
- Download the SSH Host Public Key to the IOLAN for each of the hosts that the IOLAN is connecting to.
- Download the SSH User Private Key for each user whose User Service is set to SSH.
- Copy the SSH User Public Key to the host that the user is connecting to (this is done outside the scope of the IOLAN).

SSL/TLS
Overview
When SSL/TLS is configured, data is encrypted between the IOLAN and the host/device (which must also support SSL/TLS). When you configure the SSL/TLS settings in the System section, you are configuring the default global SSL/TLS settings; you are not configuring an SSL/TLS server.
Functionality
You can create an encrypted connection using SSL/TLS for the following profiles: TruePort, TCP Sockets, Terminal (the user's Service must be set to SSL_Raw), Serial Tunneling, Virtual Modem, and Modbus.
When configuring SSL/TLS, the following configuration options are available:
- You can set up the IOLAN to act as an SSL/TLS client or server.
- There is an extensive selection of SSL/TLS ciphers that you can configure for your SSL/TLS connection; Appendix B, SSL/TLS Ciphers for a list of SSL/TLS ciphers.
Note: Some combinations of cipher groups are not available on FIPS firmware versions.
- You can enable peer certificate validation, for which you must supply the validation criteria that was used when creating the peer certificate (this is case sensitive).
Note: See Keys and Certificates for information about SSL/TLS support documents.

Default: Disabled
Validation Criteria Click this button to create peer certificate validation criteria that must be met Button for a valid SSL/TLS connection.
SSL Certificate Passphrase This is the SSL/TLS passphrase used to generate an encrypted RSA/DSA private key. This private key and passphrase are required for both HTTPS and SSL/TLS connections, unless an unencrypted private key was generated, then the SSL passphrase is not required. Make sure that you download the SSL private key and certificate if you are using the secure HTTP option (HTTPS) or SSL/TLS. If both RSA and DSA private keys are downloaded to the IOLAN, they need to be generated using the same SSL passphrase for both to work.
Cipher Suite Field Descriptions
Note: Some combinations of cipher groups may not be available on some firmware versions.
The SSL/TLS cipher suite is used to encrypt data between the IOLAN and the client. You can specify up to five cipher groups.

VPN
Overview
A Virtual Private Network (VPN) creates a secure, dedicated communications network tunnelled through another network.
You can configure the IOLAN for:
- a host-to-host Virtual Private Network (VPN) connection
- a host-to-network VPN connection
• a network-to-network VPN connection - or host/network-to-IOLAN VPN connection (allowing serial devices connected to the IOLAN to communicate data to a host/network).
In addition to being able to configure up to 64 IPsec tunnels, you can configure an L2TP/IPsec tunnel that will allow hosts to create a VPN tunnel to the IOLAN. The L2TP/IPsec VPN protocol is required by the Windows XP® operating system. Later versions of Windows® may support both VPN protocols, however check with the Windows® documentation that came with your Windows® pc.
Note: Before you enable/configure any VPN tunnels, you should configure any exceptions or you might not be able to access the IOLAN except through a VPN tunnel or the console port. See Exceptions for more information about exceptions.
Note: If you are configuring IPsec and/or L2TP/IPsec, you must also enable the IPsec service found in Security, Services navigation tree.
Functionality
The information in this section applies only to setting up IPsec VPN tunnels, not L2TP/IPsec VPN tunnels.
The IOLAN can be configured as a VPN gateway using the IPsec protocol. You can configure the VPN connection using two IOLANs as the local and remote VPN gateways or the IOLAN as the local VPN gateway and a host/server running the VPN software as the remote VPN gateway.
If the VPN tunnel is being configured for an IPv6 network that is going through a router(s), the router(s) must have manual IPv6 address entry capability, similar to what Windows Vista ^® provides.
VPN servers/clients can support various VPN parameters. However, the following parameters are REQUIRED to be set to the following values to support a VPN tunnel between the IOLAN and a VPN server/client:
perfect forward secrecy: no
protocol: ESP
mode: tunnel (not transport)
opportunistic encryption: no
aggressive mode: no
IKE Phase 1 Proposals
The following IKE Phase 1 proposals are supported by the IOLAN VPN gateway:
• Ciphers—3DES, AES
- Hashes—MD5, SHA1
- Diffic-Hellman Groups—2 (MODP1024), 5 (MODP1536), 14 (MODP2048), 15 (MODP3072), 16 (MODP4096), 17 (MODP6144), 18 (MODP8192)
ESP Phase 2 Proposals
The following ESP Phase 2 proposals are supported by the IOLAN VPN gateway:
• Ciphers—3DES, AES
• Authentication Algorithms—MD5, SHA1, SHA2
IPsec
When an IPsec tunnel becomes active, you are requiring that all access to the IOLAN go through the configured IPsec tunnel(s), so you must configure any exceptions first see (Exceptions). for more information on exceptions) or you will not be able to access the IOLAN through the network unless you are configured to go through the IPsec tunnel (you can still access the IOLAN through the Console port).

| Remote IPv4 Subnet Mask | The subnet mask of the remote IPv4 network. Keep the default value when you are configuring a host-to-host VPN connection.Default: 255.255.255.255 |
| Remote IPv6 Prefix Bits | The prefix bits of the remote IPv6 network. Keep the default value when you are configuring a host-to-host VPN connection.Default: 0 |
| Boot Action | Determines the state of the VPN network when the IOLAN is booted.Data Options:Start—Starts the VPN network, initiating communication to the remote VPN.Add—Adds the VPN network, but doesn’t initiate a connection to the remote VPN.Ignore—Maintains the VPN network configuration, but the VPN network is not started and cannot be started through the IPsec command option.When defining peer VPN gateways, one side should be defined as Start (initiate) and the other as Add (listen). It is invalid to define both gateways as Add. VPN connection time can take longer when both gateways are set to Start, as both sides will attempt to initiate the same VPN connection.Default: Start |

HTTP Tunneling
Overview
A HTTP tunnel is a firewall-safe communication channel between two IOLAN's. HTTP tunnels can transport arbitrary TCP/IP or UDP/IP data for applications such as Telnet/SSH or any other TCP application and most UDP applications.
You can configure the IOLAN for:
- a serial-to-serial HTTP tunnel connection
- a serial-to-host HTTP tunnel connection
- a host-to-host HTTP tunnel connection
- Tunnel Relay connection
See Configuring HTTP Tunnels for more information on setup requirements for these scenarios.
Functionality
The information in this section applies only to setting up HTTP tunnels.
A minimum of two IOLAN's must be configured to create a communication channel. One IOLAN must be configured as the listener and the other IOLAN must be configured as the connecting IOLAN.

Services
Overview
Services are either daemon or client processes that run on the IOLAN. You can disable any of the services for security reasons.
Functionality
If you disable any of the daemons, it can affect how the IOLAN can be used or accessed. For example, if you disable WebManager (HTTPS and HTTP) services, you will not be able to access the IOLAN with the WebManager. If you disable the DeviceManager service, the DeviceManager will not be able to connect to the IOLAN. If you do not want to allow users to Telnet to the IOLAN, you can disable the Telnet Server service; therefore, disabling daemons can also be used as an added security method for accessing the IOLAN.
By default, all daemon and client applications are enabled, except IPsec, and running on the IOLAN.

Keys and Certificates
When you are using SSH, SSL/TLS, LDAP/Microsoft Active Directory, or HTTPS, you will need to install keys and/or certificates or get server keys in order to make those options work properly. All certificates need to be created and all keys need to be generated outside of the IOLAN, with the exception of the IOLAN SSH Public keys, which already exist in the IOLAN. SSH keys must be generated using the OpenSSH format.
Certificate Authorities (CAs) such as Verisign, COST, GTE CyberTrust, etc. can issue certificates. Or, you can create a RSA or DSA self-signed certificate using a utility such as OpenSSL.

Failsafe Timer Functionality
Overview
The Failsafe Timer tab configures the I/O failsafe timer. The Failsafe Timer is enabled on a global basis and provides a trigger mechanism that can be configured for each channel when no I/O traffic/management has occurred for the specified amount of time. A Failsafe Action can be configured for each Digital Output channel, each Serial Signal Output pin (DTR and RTS), and each Relay channel to either Activate or Deactivate the output.
The Failsafe Timer has a different function when I/O Extension is enabled for Digital Output channels, Relay channels, or the Serial Signal Output pins (DTR and RTS). For I/O Extension, the Failsafe Timer provides a per channel or per serial signal output pin trigger mechanism that is activated when there are no TCP sessions for the specified amount of time.

Enable I/O Failsafe Timer Enables/disables the Failsafe Timer. This is the global setting that must be enabled to set the Failsafe Action on the channel for digital output and relay channels or output signal pins. When this timer expires because of no I/O activity within the specified time interval, the Failsafe Action set for the channel determines the action on the output. When the channel or serial signal pin is configured for I/O extension, the timer expires there are no TCP sessions for the specified time interval.
Default: Disabled
Timeout The number of seconds that must elapse before the channel/serial signal pin Failsafe Action is triggered.
Range: 1-9999

UDP Functionality
Overview
The UDP tab configures the I/O UDP broadcast settings. The I/O UDP broadcast feature periodically broadcasts the I/O channel status in a UDP message.
You can configure up to four sets of IP address entries (each entry consisting of a start and end IP address range) to broadcast I/O status data. The broadcast frequency of the UDP packets to the configured UDP IP addresses can be defined to accommodate network traffic and monitoring PC application requirements. For details of the UDP I/O datagram see I/O UDP on page 309.

Analog
Overview
Analog channels monitor current/voltage input. Note that the internal jumpers must match the software setting (by default, they are set to Current); see Analog Input Module on page 443 to find out how to set the internal jumpers.
For example, in an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity transducers, which are in place to help prevent freezer burn. If the humidity reaches a certain percentage (monitored by an Analog channel) a syslog message is sent to the Monitoring Application. The Monitoring Application then sends a command to the IOLAN via the Perle API that causes the Relay channel to activate an internal freezer dehumidifier. The relay is turned off when the Analog channel sends a clear syslog message to the Monitoring Application and the Relay channel is deactivated.

Alarm Settings Button
Click the Alarm Settings button to specify the trigger and clear levels for the alarms. Notice that the Analog Alarm Settings window has two alarm configuration views, a basic alarm view and an advanced alarm view.
See Alarm Settings on page 306 for field descriptions.
Digital Input
Overview
When the channel is set for digital input, it monitors voltage or current. Note that the internal jumpers must match the software setting and must be set to Input, which is the default; see Digital I/O Module on page 442 to find out how to set the internal jumpers.
Functionality
The Digital input channels allow you to configure the following options:
- You can choose to remember the last state change, or latch, that occurred. Your options are to latch (remember) when the state changes from inactive to active or active to inactive.
- You can choose to invert the signal, which is useful if your sensor is wired in such a way that closed is actually inactive, whereas closed is normally considered active.
- You can also configure an alarm trigger and clear mode based on whether the Digital input is active or inactive, sending an email, syslog message, and/or SNMP trap when the alarm is triggered or cleared.
In an industrial freezer warehouse example, a D4 is used to monitor the open door sensor, so that every time a freezer door is opened, an alarm is triggered and a syslog message is sent to a syslog server, where the monitoring application notes the time.

Digital Output
Overview
When the channel is set for digital output, either voltage is applied to the channel or the channel is grounded. Note that the internal jumpers must match the software setting and must be set to Output (by default, they are set to Input); see Digital I/O Module on page 442 to find out how to set the internal jumpers.
Functionality
The Digital output channels support three types of Digital output: sink (voltage), source (ground), and sink and source (apply voltage or ground). For the output type, you can configure the following options:
- You can choose to manually activate/deactivate the Digital output.
- You can choose to manually activate/deactivate the Digital output and then specify that the Digital output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.
- You can choose to manually activate/deactivate the Digital output and then specify a delay before the output goes from inactive to active or active to inactive.
- You can also specify a failsafe action that can either activate or inactivate the Digital output when the failsafe timer is triggered (see Failsafe Timer Functionality on page 284 for more information).
In an industrial freezer warehouse, the IOLAN D4 is used to monitor the freezer doors. When one of the industrial freezer doors are left open for more than five minutes, the Monitoring Application (using the Perle API) starts the Digital output sink, causing the strobe light on top of the offending freezer to activate.

Relay
Overview
Relay channels can open or close a contact for a higher voltage circuit using a lower level control voltage. The Relay output channels work as a physical on/off switch, and are used to drive higher voltage devices with a lower controlling voltage.
You can configure the following Relay output channel options:
- You can choose to manually activate/deactivate the Relay output.
- You can choose to manually activate/deactivate the Relay output and then specify that the Relay output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.
- You can choose to manually activate/deactivate the Relay output and then specify a delay before the output goes from inactive to active or active to inactive.
- You can also specify a failsafe action that can either active or inactivate the Relay output when the failsafe timer is triggered (see Failsafe Timer Functionality on page 284 for more information).
In an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity transducers, which are used to help prevent freezer burn. If the humidity reaches a certain percentage (monitored by an Analog channel) a syslog message is sent to the Monitoring Application, causing the Relay channel to activate an internal freezer dehumidifier. The Relay channel is deactivated when the Analog channel sends a clear syslog message to the Monitoring Application and the Relay channel is deactivated.

Digital I/O Extension
Overview
The Digital I/O extension feature connects a digital input signal to digital output(s)/relay(s) and/or a TCP/IP application over an IP network. Therefore, when the state of the digital input changes, you can also change the state of the digital output or relay channel or output serial signal pin on a local I/O channel(s), other IOLAN I/O channels, other IOLAN serial signal pins, or the data can be sent to an application(s).
For example, when the door opens (I/O digital input sensor) in a factory, a light goes on in the reception office (remote IOLAN relay channel), and the door open/close is logged by an application on a remote host.

style E fill:#cff,stroke:#333
Functionality
The Digital I/O extension feature requires the digital input to be connected to one or more digital outputs/relays (local or on another IOLAN model), output serial signal pins, and/or TCP/IP applications. In order to create a successful connection between the input and output or application, one side must be must be set to Listen for connection and the other side must be set to Connect to. When the state of an input channel changes, a message is sent to all sessions currently associated with that channel.
When the IOLAN is communicating to an application, there is no need for the output channel or application to respond to messages from the input channel. Each input channel is reported individually, so the receiving application gets the status only at the point at which the channel state has changed.
The message format (from input channel to output channel/application) consists of 20 bytes per status; 10 bytes are currently used and 10 are being reserved for future use.
| Message Type(1 Byte) | Input Number(1 Byte) | IOLAN MACAddress (6 Bytes) | Current AlarmState (1 Byte) | Current Statusof Input (1 Byte) | Reserved(10 Bytes) |
- Message type: (1 Byte)
- 0 = Digital input status
- 1 = Serial I/O status
• Input number: (1 Byte)
- Digital input will be 1, 2, 3, or 4 to represent the channel number
- Serial I/O will be 5 = DSR, 6 = DCD, or 7 = CTS
• MAC Address of the IOLAN sending the input information. (6 Bytes)
• Current Alarm State: (1 Byte)
- 0 = Not in alarm
- 1 = In Alarm
• Current Status of Input: (1 Byte)
- 0 = Inactive for digital input.
• 1 = Active for digital input.
- Reserved for future use. Reserved bytes will have the value 0x00. (10 Bytes)
Applications should be written in such a way so that they look at the Message type byte to determine the format of the message. If the application encounters a Message type it does not recognize, it should discard the message and read the next 20 byte block.
Field Descriptions
The Local connection option is different depending on whether you are configuring a Digital Input or a Digital Output/Relay channel. The Local connection option for Digital Input lists all the local Digital Output channels or output serial signal pins that it is associated with. Digital Input can be connected to multiple local Digital Output or Relay channels or output serial signal pins. However, a Digital Output can only be associated with one Digital Input channel or input serial signal pin. The Local connection option for Digital Output configures the specific local Digital Input channel or input serial signal pin on the same IOLAN that it is to be connected to.
For a description of the SSL/TLS parameters (not available when Local connection is configured), see SSL/TLS Settings Tab Field Descriptions on page 152.

I/O UDP
Industrial applications often monitor the status of I/O devices such as sensors, alarms, relays, etc. by polling for I/O data. The IOLAN's I/O UDP feature can help to minimize network traffic by broadcasting I/O status to industrial applications on specified intervals, providing I/O status in a timely manner.
The IOLAN's I/O UDP broadcast feature sends the status of attached I/O devices to defined hosts on the network. Depending upon the IOLAN model and the configuration of the I/O channels, the UDP packet contains the current status and/or data of each enabled I/O channel or serial pin signal.
UDP Unicast Format
PC applications must be able to interpret the UDP packet to obtain I/O channel status and data. This section provides the detailed structure of the UDP datagram and its data format.
UDP Broadcast Packet
| Version(1 Byte) | Total Packet Length(2 Bytes) | Analog Section | Digital/Relay Section | Serial Pin Signal Section |
Each section, with the exceptions of the Version and Total Packet Length sections, is comprised of its own subset of bytes.
Note: All 2 byte values are in big Endian (network) order. All 4 byte values are IEEE 754 single precision floating point numbers in big Endian (network) order.
- Version—The current version of the format of I/O UDP broadcast packet.
• Total Packet Length—The total length of the UDP packet. - Analog Section—The Analog Section of the UDP packet, which contains data/status of the Analog I/O channels. The Analog Channel Data subsection (within the Analog Section) will only exist if the channel(s) is enabled.
- Digital/Relay Section—The Digital/Relay Section of the UDP packet, which contains status of Digital and Relay I/O channels. The Channel Data subsection within the Digital/Relay Section will always be present.
- Serial Pin Signal Section—The Serial Pin Signal Section of the UDP packet, which contains the status of the IOLAN's serial port's control signal pins. The Serial Pin Signal Data subsection within the Serial Signal Pins Section will always be present.
Analog Section
The Analog Section of the UDP packet is comprised of I/O data for each enabled Analog channel.
Note: If the IOLAN I/O model does not support Analog channels, the Analog Channel Data subsection of the Analog Section will NOT be present in the UDP packet.
| Section Length | Channel Enabled | Analog Channel Data (for each enabled channel) | |||||
| 2 Bytes | Byte curRaw | Value2 Bytes | minRawValue2 Bytes | maxRawValue2 Bytes | curEngValue4 Bytes | minEngValue4 Bytes | maxEngValue4 Bytes |
- Section Length—The total length of the Analog section (this value will vary, the field length is 2 Bytes). This value will vary because it will contain one Analog Channel Data subsection (18 bytes) for each Analog channel that is enabled.
- Channel Enabled—The Channel Enabled field is 1 byte in least significant bit order, for each channel. If the channel is enabled, the bit is set to 1. If the channel is disabled, the bit is set to 0 (zero).
| Channel Enabled (1 Byte, one bit for each channel) | |||||||
| Channel 4 | Channel 3 | Channel 2 C | Channel 1 | ||||
- Analog Channel Data—Consists of Analog Channel Data for each enabled Analog channel on the IOLAN. If an Analog channel is disabled, there is no data for that channel. Therefore, the Analog Section will contain the Section Length value, the Channel Enabled value, and 18 bytes of I/O data for each enabled Analog channel. For example, an IOLAN I/O model with four Analog channels that has only three of those Analog channels enabled will contain 54 bytes of Analog Channel Data (18 bytes * 3 Analog channels).
The following values make up the Analog Channel Data for each enabled Analog channel:
- curRawValue—The current raw value received by the channel.
- minRawValue—The minimum raw value received by the channel until it is cleared.
- maxRawValue—The maximum raw value received from the channel until it is cleared.
- curEngValue—The current raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature.
- minEngValue—The minimum raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature until it is cleared.
- maxEngValuc—The maximum raw value that has been converted to voltage/current for Analog or Celsius/Fahrenheit for Temperature until it is cleared.
Digital/Relay Section
The Digital/Relay Section of the UDP packet provides the status of Digital and Relay channels. The data for the status of each channel is represented by 1 byte, with each bit representing a channel (least significant bit format).
| Note: | The Digital/Relay Channel Data subsection is present in the UDP packet regardless of whether or not the IOLAN model supports Digital/Relay channels. |
| Length | Channel Enabled | Digital/Relay Channel Data (1 Byte, one bit for each channel) | |||||||
| 2 Bytes 1 | Byte Channel | 4 Channel | 3 Channel | 2 Channel | 1 | ||||
- Length—The length of Digital/Relay Section within the UDP packet (this value will always be 2 Bytes).
- Channel Enabled—This is based on the configuration of the Digital/Relay channels. The Channel Enabled field is 1 byte in least significant bit order, for each channel. If the channel is enabled, the bit is set to 1. If the channel is disabled, the bit is set to 0 (zero).
| Channel Enabled (1 Byte, one bit for each channel) | |||||||
| Channel 4 | Channel 3 | Channel 2 C | Channel 1 | ||||
- Digital/Relay Channel Data—Each bit represents a channel status, 1 for on or 0 for off (unless the channel has been configured to be inverted, in which case 0 is on and 1 if off).
Serial Pin Signal Section
The Serial Pin Signal Section of the UDP packet provides the status of the serial pin signals from the IOLAN's serial port. Each serial pin signal (DSR, DTR, CTS, etc.) is mapped to a bit in the 1-byte data section.
| Note: | The Serial Pin Signal Data subsection is present in the UDP packet regardless of whether or not the serial port is configured for the Control I/O profile or the serial pin signals are enabled. |
| Length | Pin Enabled | Serial Pin Signal Data (1 Byte, one bit for each signal) | |||||||
| 2 Bytes 1 | Byte RTS DTR CTS DCD DSR | ||||||||
- Length—The total length of the Serial Pin Signal Data (this value will always be 2 Bytes).
- Pin Enabled—This based upon the configuration of the signal pins on the serial port. When the serial port profile is set to Control I/O and a serial pin signal(s) is enabled, the bit is set to 1. For any serial pin signals that are disabled, the bit is set to 0 (zero) and any data associated with those serial pin signals should be ignored.
| Pin Enabled (1 Byte, one bit for each serial pin signal) | |||||||
| RTS | DTR | CTS | DCD | DSR | |||
- Serial Pin Signal Data—1 byte with each bit being set to high (1) or low (0) for the appropriate serial pin signals.
UDP Unicast Example
For an example of the I/O UDP unicast, see the sample program, ioudpbcast.c, found on your CD-ROM.
I/O Modbus Slave
If you have a Modbus serial or TCP application, it can access I/O connected to the IOLAN when the I/O Global Modbus Slave is enabled. You must supply a unique UID for the IOLAN, as it will act as a Modbus Slave.

TruePort I/O
You can see a sample API I/O over TruePort program called ioapiotp.c on the CD-ROM.
TruePort/Modbus Combination
If you have a Modbus serial application running on a PC that is connected to a network, you can use TruePort as a virtual serial connection to communicate with the IOLAN over the network to access I/O data. You also have the option of enabling SSL as a security option to encrypt the data that is communicated between the IOLAN and the host machine (SSL/TLS must be configured in the Server settings and on the TruePort host).

Accessing I/O Data Via TruePort
Introduction
Analog and Digital I/O data, as well as output control, can be accessed in several ways. To have access from an application running on a workstation or server, the I/O Applications Program Interface (API) provided within Trueport can be used. This API uses a command/response format to get or set data on each individual I/O channel register. A sample program (ioapiotp.c) demonstrating typical usage can be found on the IOLAN product CD-ROM.
Setup
After TruePort has been properly installed and configured on the workstation or server and initiated from the application, it will setup a connection to the appropriate IOLAN. It will then be available to relay commands to the IOLAN and communicate responses back the application. TruePort will create a COM port to which the application can write commands to and read responses from. Since all communications are done via this COM port, the application need only use standard serial communication interface calls.
The following steps should be taken:
-
Install the Trueport software on the server or workstation on which the application will be running.
-
Configure the virtual communication port (COM) (see Trueport User Guide for details).
-
Run the application. Typically the application will:
a. Open the COM port.
b. Send Commands to the COM port using standard write commands.
c. Read Responses from the COM port using standard read commands.
Note: All commands are forwarded to the IOLAN over the network where the specific I/O channel registers are modified or read, and then responses are sent back to TruePort where they will be made available to be read from the COM port.
d. Once the desired operations are completed, the COM port can be closed.
Format of API Commands
There are two groups of commands:
- Get Commands—Retrieve values of the I/O channel registers
- Set Commands—Set values on the I/O channel registers.
Note: All commands need to be written to the COM port as a single write.
I/O Channel registers are all assigned unique addresses, which need to be referenced in all of the commands. Please refer to the documentation specific you the applicable mode, for the list and addresses of all the registers.

Get Commands
The following tables show the general structure to be used for Get commands.
Note: Numeric values provided in the API documentation are in Hexadecimal (Hex) format.
Command Format
| Byte(s) # of Bytes Value | ||
| 1 1 Command Code: | ||
| 0x01 – Get “coils” (Boolean register)0x03 – Get “holding registers” (R/W registers)0x04 – Get “input registers” (R only register) | ||
| 2-3 | 2 | Starting register number (seeA4/T4 Registerson page 315,A4D2/A4R2 Registerson page 316, orD4/D2R2 Registerson page 317 for this value). |
| 4-5 | 2 | Number of registers to read. If this value is greater than 1, the response will contain the values of multiple consecutive registers. |
Response Format
| Byte(s) # of Bytes Value | ||
| 1 | 1 | Command that this is a response to. If an error has been detected, the command value will have the high bit set (OR with 0x80). For example: The command is 0x04, so the command field in the response would be 0x84. |

Set Commands
The following tables show the general structure to be used for set commands.
Note: Numeric values provided in the API documentation are in Hexadecimal (Hex) format.
Command Format
| 1 1 Command Code (in hex): | ||
| 0x0F – Set “Boolean registers” (R/W coils)0x10 – Set “holding registers” (read/write registers) | ||
| 2-3 | 2 | Starting register number (seeA4/T4 Registerson page 315,A4D2/A4R2 Registerson page 316, orD4/D2R2 Registerson page 317 for this value). |
| 4-5 | 2 | Number of registers to set. If this value is greater than 1, the response will contain the values of multiple consecutive registers. |
| 6 1 The length of the data (in bytes) to be written to the registers. | ||
| 7-n n Data to be written to the registers. | ||
| If accessing registers which are 2 or 4 bytes, the data is in Network order (Big endian) format (that is, MSB, LSB).For Boolean registers, the value field will be a bit field with the LSBit corresponding to the IO channel referenced by the starting register. | ||
Successful Response Format
| 1 1 Command code (from request). | |
| 2 | Starting register number (see A4/T4 Registers on page 315,A4D2/A4R2 Registers on page 316, or D4/D2R2 Registers on page 317for this value) from request. |
4 2 Number of registers written.
Unsuccessful Response Format
| 1 | 1 | Command that this is a response to. If an error has been detected, the command value will have the high bit set (OR with 0x80). For example: The Command is 0x10, so the command field in the response would be 0x90. |
| 1 | 1 | Error code, see Error Codes on page 324. |
Example 1: Turn on the first relay on a D2R2 unit.
The first relay (R1) is a digital out coil register with a decimal value of 6659 (hex 0x1A03).

12Configuring Clustering
Introduction
Clustering is a way to provide access to the serial ports of many IOLANs through a single IP address.
Clustering Slave List

Overview
The IP address that will be used to access all clustered serial ports will be that of the Master IOLAN in the cluster. All other IOLANs in the cluster will be referred to as Slave IOLANs. Users can also access slave serial ports using EasyPort Web; EasyPort Web is automatically launched when a user types in the IP address of the Master IOLAN in a web browser. If the user has Admin privileges, the WebManager will first be displayed with an option to proceed to EasyPort Web.
The Clustering Slave List window displays the slave IOLAN entries and the number of ports on those slave IOLANs.
Note: No special configuration is required on the Slave IOLANs to enable this functionality.

13Configuring the System
Introduction
This chapter describes the alerts (email and syslog) that can be configured for the IOLAN and the advanced options (SNMP, time, custom applications/plugins, and other miscellaneous configuration options) that you will want to look at to see if they are required for your implementation.
Alerts
Email Alerts

text_image
Configuration Network Serial Users Security I/O Interfaces Clustering System Alerts Email Alert Syslog Management SNMP Time Custom App/Plugin AdvancedOverview
Email notification can be set at the Server and/or Line levels. You can set email notification at these levels because it is possible that the person who administers the IOLAN might not be the same person who administers the serial device(s) attached to the IOLAN port. Therefore, email notification can be sent to the proper person(s) responsible for the hardware.
Functionality
Email notification requires an SMTP host that is accessible by the IOLAN to process the email messages sent by the IOLAN. When you enable email notification at the Server level, you can also use those settings at the serial port level, or you can configure email notification specifically for each serial port. When you choose an event Level, you are selecting the lowest notification level; for example, if you select Level Error, you will get notifications for all events that trigger Error, Critical, Alert, and Emergency messages. The level order, from most inclusive to least inclusive, is as follows: Debug, Info, Notice, Warning, Error, Critical, Alert, Emergency.
The following events trigger an email notification on the System for the specified Level:
- Reboot, Alert Level
• IOLAN System Failure, Error Level
• Authentication Failure, Notice Level
- Successful Login, Downloads (all), Configuration Save Commands, Info Level

Outgoing Mail Server The SMTP host (email server) that will process the email notification request. This can be either a host name defined in the IOLAN host table or the SMTP host IP address.
HTTP Tunnel Specify the HTTP tunnel to be used for this connection.
Username If your mail server requires you to authenticate with it before it will accept email messages, use this field to configure the authorized user name. Maximum size of user name is 64 characters.
Password Enter the password associated with the user configured in "Username". Maximum size of password is 64 characters.
Encryption Choose the type of encryption desired. Valid options are;
None - All information is sent in the clear.
SSL - Select this if your email server requires SSL.
TLS - Select this if your email server requires TLS
Verify Peer Certificate When checked this will enable the validation of the certificate presented by the email server. To validate the certificate, you will need to download the
When checked this will enable the validation of the certificate presented by the email server. To validate the certificate, you will need to download the appropriate CA list into the IOLAN. If the certificate is not found to be valid, the communication with the email server will be terminated. No authentication will take place and the email message will not be forwarded to the email server. If this option is not checked, the certificate validation will still be attempted but if it fails, a syslog message will be generated but the authentication and forwarding of the email will still take place.
Default: Enabled if SSL or TLS encryption is selected. Disabled if no encryption is selected.
TCP Port This is the TCP port used to communicate with the email server.
Default: 25 for non-SSL, 465 if SSL/TLS is used
NTLM Domain This field is only used if SPA authentication is performed with the email server. It may or may not be required. If the email server does not expect this field, it can be left blank.
Syslog
Overview
The IOLAN can be configured to send system log messages to a syslog daemon running on a remote host if the Syslog service is activated. You can configure a primary and secondary host for the syslog information and specify the level for which you want syslog information sent.
Note: You must ensure that the Syslog Client service in the Security, Services window is enabled (by default it is enabled) for these settings to work.

Management
SNMP
Overview
If you are using SNMP to manage/configure the IOLAN, or to view statistics or traps, you must set up a User in SNMP version 3 or a Community in SNMP version 1.2 to allow your SNMP manager to connect to the IOLAN; this can be done in the DeviceManager, WebManager, CLI, or Menu. You must then load the perle-sds.MIB (found on the CD-ROM packaged with the IOLAN) file into your SNMP manager before you connect to the IOLAN.
Note: Ensure that the SNMP service found in the Security, Services page is enabled (by default it is enabled).

Functionality
The IOLAN has a real-time internal clock, allowing the date and time to be set and viewed. It will maintain the time over a short power outage and after reboots of the IOLAN. If you do not set the time, it will start the clock at the factory set time.
When you set the IOLAN's time, the connection method and time zone settings can affect the actual internal clock time that is being set. For example, if you are connecting to the IOLAN through the DeviceManager and your PC's time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN's time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN's time is actually three hours ahead of your PC's time. Therefore, if you set the IOLAN's time to 2:30 pm in the DeviceManager, the IOLAN's actual internal clock time is 5:30 pm. This is the only configuration method that interprets the time and converts it between time zones, as necessary.
Network Time Tab Field Descriptions
You can configure your NTP/SNTP client in the IOLAN to automatically synchronize the IOLAN's time.

Custom App/Plugin
Overview
You can create custom applications for the IOLAN by using the Perle SDK. See the SDK Programmer's Guide (the SDK and guide are accessible via a request form located on the Perle website at www.perle.com/supportfiles/SDK_Request.shtml) for information about the functions that are supported. You must download the program and any ancillary files to the IOLAN and set the Serial Port Profile to Custom App/Plugin to run a custom application. You must also specify the program executable in the Command Line parameter.
A custom application or plugin can be run on the serial port. In this situation, the application will start once the serial port is activated and operate solely on the context of that serial port and any network communications related to that serial port. You could run a different custom application on each serial port. The serial port custom application or plugin is configured by specifying the Custom App/Plugin profile for the serial port.
The system level custom application or plugin will begin execution immediately following the system startup. It runs on the context of the whole system and can access network communications as well as any or all serial ports.
Field Description

When you upload a configuration to the DeviceManager, you are uploading the IOLAN's working configuration file. In most other configurators (the exception being SNMP), you are always seeing the working configuration file.
In DeviceManager, select Tools, Upload Configuration from IOLAN. The working configuration file will automatically be loaded into the DeviceManager.
Specifying a Custom Factory Default Configuration
When you receive the IOLAN, it comes with a factory default configuration that the IOLAN can be reset to at any time. Administrators might find it useful to customize the factory default configuration file, so that if the IOLAN gets reset to its factory defaults, it will be reset to defaults that the Administrator specified.
There are two ways you can set the custom factory default configuration:
- Download a file to the IOLAN—You can download a custom factory default file to the IOLAN using any of the configuration methods. In DeviceManager, you must connect to the IOLAN and then select Tools, Advanced, Custom Files, Custom Factory Default Configuration and then specify the file. In WebManager, you must connect to the IOLAN and then select Administration, Reset, Factory Defaults, Set Current Configuration as Factory Default.
- Download the current configuration to the IOLAN—You can specify the configuration that you are working with/on as the custom factory default configuration using any of the configuration methods (you must be connected to the IOLAN). In DeviceManager, select Tools, Advanced, Set Factory Default to IOLAN. In WebManager, select Administration, Reset, Factory Defaults, Get and Set Factory Default Configuration File.
Resetting the IOLAN to the Default Configuration
The RESET button is available on all IOLAN models (except medical unit models). The button allows you to reset the IOLAN to its Perle or custom factory default configuration. The Power/Ready LED color and the resetting of the IOLAN default configuration vary depending on how long you press and hold the RESET button, as shown in the table below.
| When you press and hold the RESET button for... | LED color IOLAN system status | |
| Less than 3 seconds Blinking amber Reboots | ||
| Between 3 and 10 seconds | Blinking amber, then turns solid amber when you release the RESET button | Reboots and resets the configuration to the factory default (either the Perle or custom default configuration) |
| Over 10 seconds Blinking amber, then turns solid amber when you release the RESET button | Reboots and resets the configuration to the Perle factory default configuration | |
Downloading IOLAN Firmware
To upgrade the IOLAN firmware (software):
- In DeviceManager, select Tools, Advanced, Download Firmware to IOLAN. You can browse to the firmware location. Once the firmware download is complete, you will be prompted to reboot the IOLAN. You can choose to reboot the IOLAN at another time by selecting Tools, Reset, Reboot IOLAN.
- In WebManager, under the Administration option, select Update Firmware. Either browse to the firmware file and then click the Upload button or configure the TFTP or SFTP server and click the Upload button. Note: If you use the TFTP or SFTP option, the specified TFTP or SFTP server must be on the same subnet as the IOLAN.
Upgrading the firmware does not affect the IOLAN's configuration file or downloaded custom files.
Calibrating I/O
All I/O channels are factory calibrated and should not need recalibration during initial use. However should calibration be required, you can recalibrate in DeviceManager or WebManager. In DeviceManager, you calibrate the I/O channel(s) by selecting Tools, I/O Channels, Calibrate. In WebManager, you calibrate the I/O channel(s) by selecting I/O Channels, Calibrate.
Calibrating Analog Input
To calibrate an Analog input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to voltage, you cannot calibrate it for current. The voltage range configured for this channel will also dictate what is being calibrated. For example, if this channel is configured for a range of +/-10V, calibrating this channel will calibrate all channels which are configured for +/-10V. During the calibration process, you will be asked to apply the minimum and maximum configured range value to the channel; for example, to calibrate for voltage +/- 10V, you will be prompted to first apply -10V and then +10V to the channel.
Also, you cannot actively calibrate disabled channels (although, for Voltage, if you enable the channel and then set it for a range that has already been calibrated for another channel, it will also be calibrated).
Calibrating Voltage
When calibrating the IOLAN Analog input for voltage, you will need a calibration meter that is better than .1% volts precision. When you calibrate one channel, all voltage channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are also automatically calibrated.
Calibrating Current
When calibrating the IOLAN Analog input for current, you will need a calibration meter that is better than .1% current precision. Each channel needs to be calibrated individually.
Calibrating Temperature Input
To calibrate an Analog (Temperature) input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to thermocouple, you cannot calibrate it for RTD. During the calibration process, you will be asked to apply the minimum and maximum range value to the channel in either mV or Ohms; for example, to calibrate for thermocouple J 0 to 760C, you will be prompted to first apply -80mV and then +80mV to the channel.
Also, you cannot actively calibrate disabled channels (although if you enable the channel and then set it for the type of thermocouple or RTD that has already been calibrated on another channel, it will also be calibrated).
Calibrating Thermocouple
When calibrating the IOLAN Analog input for thermocouple, you will need a calibration meter that is better than .15% accuracy. When you calibrate one channel, all thermocouple channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are automatically calibrated.
Calibrating RTD
When calibrating the IOLAN Analog input for RTD, you will need a resistor that is better than .05% Ohms accuracy. When you calibrate one channel, all RTD channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are automatically calibrated.
Calibrating Analog Channels
Analog Input can be calibrated for Analog and Temperature IOLAN models.

You can reset the I/O channels calibrations to the factory calibrations in DeviceManager by selecting Tools, I/O Channels, Reset Calibrate Data or in WebManager by selecting Administration, Reset, I/O Calibration.
Setting the IOLAN's Date and Time
When you set the IOLAN's time, the connection method and time zone settings can affect the actual internal clock time that is being set. For example, if you are connecting to the IOLAN through the DeviceManager and your PC's time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN's time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN's time is actually three hours ahead of your PC's time. Therefore, if you set the IOLAN's time to 2:30 pm in the DeviceManager, the IOLAN's actual internal clock time is 5:30 pm. This is the only configuration method that interprets the time and converts it between time zones, as necessary.
All other configuration methods set the IOLAN's internal clock time to the time specified, with no interpretation.
To set the IOLAN's system clock in DeviceManager, select Tools, Advanced, Set Unit Time/Date and in WebManager select Administration, Date/Time. The Set Date/Time window is displayed.

text_image
Set Date/Time (Eastern Standard Time) Date: 20/2007 Time: 11:09:39 AM Use the PC's Date/Time Set Date/Time CancelConfigure the following parameters:
Date The IOLAN's date. The format of the IOLAN's date is dependent on the Windows operating system and regional settings.
Time

For example, if your PC's time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN's time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN's time is three hours ahead of your PC's time. If you set the IOLAN's time to 2:30 pm, the IOLAN's actual internal clock time is 5:30 pm.
Use the PCs Date/Time
When enabled, sets the IOLAN's time to the PCs time. Default: Enabled
This option is unique to the DeviceManager.
Rebooting the IOLAN
When you download any file (configuration, keys, certificates, firmware, etc.) to the IOLAN, you must reboot the IOLAN for it to take effect by selecting Tools, Reset, Reboot Server in DeviceManager and Administration, Reboot Unit in WebManager.
Resetting Serial Port Statistics
You can reset the IOLAN's serial port/s statistics back to zero.
Resetting the IOLAN to Factory Defaults
You can reset the IOLAN to its factory default configuration by selecting Tools, Reset, Reset to Factory Default in DeviceManager and Administration, Reset, Factory Defaults in WebManager.
The IOLAN will automatically reboot itself with the Perle factory default or custom factory default configuration.
Resetting the SecurlD Node Secret
If you are using SecurID external authentication, you can select Tools, Reset, Reset SecurID Node Secret in DeviceManager and Administration, Reset, SecurID Secret in WebManager to reset the node secret. You do not need to reboot the IOLAN for this to take effect, it works instantly.
Language Support
Two language files, in addition to English, are supplied on the supplemental CD, French and German. You can use any of these language files to create a translation into a language of your choice. You can download the language file (whether the language is supplied or translated) into the IOLAN and select the Language option of Custom Language or Customlang (custom language), making the Menu and CLI field labels display in the desired language.
You can view Menu or CLI in one other language only (as well as English). If you download another language file, this new language will replace the first language you downloaded.
You can revert to English at any time; the English language is stored permanently in the IOLAN and is not overwritten by your new language. Each user logged into the IOLAN can operate in either English or the downloaded language.
Loading a Supplied Language
This section describes how to download a language file using the CLI, since it is the least intuitive method. French and German language files are provided on the supplemental CD.
To load one of the supplied languages into the IOLAN, so the Menu or CLI fields appear in another language, do the following:
-
Open the supplemental CD and identify the language file, either Iolan_ds_French.txt or Iolan_ds_German.txt, or supply one of your own translated files.
-
Copy the language file to a host machine on the network; place it in the main file system or on the main hard drive.
-
Either use the TFTP/SFTP defaults in the IOLAN or, configure as necessary, TFTP/SFTP in the IOLAN.
-
In the CLI of the IOLAN, enter the host IP address and file name; for example, netload customlang 172.16.4.1 /temp/Iolan_ds_French.txt snetload customlang 172.16.4.1 /temp/Iolan_ds_French.txt
The IOLAN will download the language file via TFTP or SFTP.
In DeviceManager select Tools, Advanced, Custom Files and then select Download Custom Language File and browse to the language file. In WebManager select Administration, Custom Files and then specify the Custom Language File option and browse to the language file.
-
To set an individual user to the new language, go to the Users menu and, in the Language field select Customlang. In the CLI (only) you can set individual users or all users to the new language; see the set user * command.
-
The user will see the change of language when he/she logs out (Main Menu, Sessions Menu, Logout) and logs back into the IOLAN. If, as Admin user, you change your language setting to Customlang, you will see the text menus display in the new language when you save and exit the Change User form. Users with Level Normal can also change their display language.
Note: If you download a new software version, you can continue to use your language unchanged; however, we recommend translating the new strings, which will be added to the end of the language file. A Reset to Factory Defaults will reload the Customlang as English. On successful download, the Customlang in the IOLAN will be overwritten by the new language.
Translation Guidance
To help you with your translation, of supplied ASCII text language files we offer the following guidance:
- The IOLAN will support languages other than English (and the supplied German and French languages). The English language file, english.txt, displays the character length of each line at the beginning of the line. If a translated line goes over that character length, it will be displayed truncated in the Menu or CLI.
- Translate line for line, do not omit lines if you do not know the translation; leave the original untranslated text in place. Also, you must maintain the same sequential order of lines. It is a good practice to translate the file using a text editor that displays line numbers, so you can periodically verify that the line sequence has not changed from the original file (by comparing it to the original file).
- Keep all translations in quotes, otherwise the line will not display properly.
• Each line must end with a carriage return. - If a line contains only numbers, for example 38400, leave that line in place, unchanged (unless you are using a different alphabet).
Software Upgrades and Language Files
If you receive a software upgrade for the IOLAN, the language files supplied on the supplemental diskette/CD might also have been updated. We will endeavour to provide a list of those changes in another text file on the same supplemental CD.
Note: The upgrade of your software (firmware) will not change the display of the language in the Menu or CLI.
If you are already using one of the supplied languages, French or German, you probably want to update the language file in the IOLAN. Until you update the IOLAN with the new language file, new text strings will appear in English.
If you are already using a language translated from an earlier version, you probably want to amend your translation. When a language file is updated, we will try to maintain the following convention:
- New text strings will be added to the bottom of the file (not inserted into the body of the existing file).
- Existing text strings, if altered, will be altered in sequence; that is, in their current position in the file.
- The existing sequence of lines will be unchanged.
- Until you have the changes translated, new text strings will appear in the Menu or CLI in English.
Downloading Terminal Definitions
All terminal types can be used on the IOLAN. Some terminal types which are not already defined in the IOLAN, however, are unable to use Full Screen mode (menus) and may not be able to page through sessions properly. When installed, the IOLAN has several defined terminal types—Dumb, WYSE60, VT100, ANSI, TV1925, IBM3151, VT320-7, and HP700/44.
If you are not using, or cannot emulate, any of these terminal types, you can add up to three additional terminal definitions to the IOLAN. The terminal definitions can be downloaded from a TCP/IP host.
To download terminal definitions, follow these steps:
- Decide which TCP/IP host you are going to use. It must be a machine with enabled.
- Configure SFTP/TFTP in the IOLAN as necessary.
- Select Tools, Advanced, Custom Files from the menu bar in DeviceManager and Administration, Custom Files in WebManager.
- From the File Type drop-down, select Download Terminal Definition. Select the terminal definition option 1, 2, or 3 and then browse to the terminal definition file that is being downloaded to the IOLAN.
- In the Terminal profile, select the Terminal Type Termx that you custom defined.
Creating Terminal Definition Files
To create new terminal definition files, you need to copy and edit the information from the termininfo database.
- On a UNIX host, change directory to /usr/lib/terminfo/x (where x is the first letter of the required terminal type). For a Wyse60, for example, you would enter the command cd /usr/lib/terminfo/w.
- The termcap files are compiled, so use the command infocmp termfile to read the required file (for example: infocmp wy60).
- Check the file for the attribute xmc#n (where n is greater than or equal to 1). This attribute will corrupt menu and form displays making the terminal type unsuitable for using Menu mode.
- If the terminal definition is suitable, change to a directory of your choice.
- Rename and copy the file to the directory specified at step 4. using the command infocmp termfile > termn where n is greater than or equal to 1; (for example, infocmp wy50 > term1). Make sure the file has global read and execute permission for its entire path.
- Edit the file to include the following capabilities in this format:
term=
acsc=
bold=
civis=
clear=
cnorm=
cup=
rev=
rmacs=
rmso=
smacs=
smso=
page=
circ=
For example:
term=AT386 | at386| 386AT |386at |at/386 console
acsc=jYk?1Zm@qDtCu4x3
bold=\E[1m
civis=
clear=\E[2J\E[H
cnorm=
cup=\E[%i%p1%02d;%p2%02dH
rev=\E4A
rmacs=\E[10m
rmso=\E[m
smacs=\E[12m
smso=\E[7m
page=
circ=n
Note: As you can see from the example, capabilities which are not defined in the termininfo file must still be included (albeit with no value). Each entry has an 80 character limit.
On some versions of UNIX, some of the capabilities are appended with a millisecond delay (of the form
The ‘acsc’ capability, if defined, contains a list of character pairs. These pairs map the characters used by the terminal for graphics characters to those of the standard (VT100) character set.
Include only the following character pairs:
jx, kx, lx, mx, qx, tx, ux and xx
(where x must be substituted by the character used by the terminal). These are the box-drawing characters used to display the forms and menus of Menu mode. They must be entered in this order.
The last two capabilities will not be found in the termininfo file. In the page field you must enter the escape sequence used by the terminal to change screens. The circ field defines whether the terminal can use previous page and next page control sequences. It must be set to y or n. These capabilities can be found in the documentation supplied with the terminal.
Resetting Configuration Parameters
You can reset the IOLAN to its factory default settings (this will reset it to the Perle factory default or custom factory default settings, depending on what has been configured) through any of the following methods:
- You can push in the recessed button at the back of the IOLAN hardware for three to ten seconds (pushing it in and then quickly releasing will just reboot the IOLAN)
• DeviceManager, select Tools, Reset, Reset to Factory Defaults
• CLI, at the command line type, reset factory
WebManager, select Administration, Reset, Factory Default, and then click the Reset to Factory Defaults button - Menu, select Network Configuration, Reset to Factory Defaults
• SNMP, in the adminInfo folder, Set the adminFunction variable to 2
Lost admin Password
If the admin user password is lost, there are only two possible ways to recover it:
- reset the IOLAN to the factory defaults
- have another user that has Admin level rights, if one is already configured, reset the admin password

Introduction
This chapter provides examples of how to integrate the IOLAN within different network environments or applications. Each scenario provides an example of a typical setup and describes the configuration steps to achieve the IOLAN functionality feature.
Configuring Modbus
This sections provides a brief overview of the steps required to configure the IOLAN for your Modbus environment. You can read the Modbus Gateway Settings and Modbus Serial Port Settings sections for more specific information about the Modbus settings.
Overview
This section describes the high-level steps required to configure the IOLAN as a Modbus Master or Slave Gateway.
Configuring a Master Gateway
To configure a Master Gateway (Modbus Master connected to the serial side of the IOLAN), do the following:
- Set the serial port that is connected to the serial Modbus Master to the Modbus Gateway profile.
- In the Modbus Gateway profile on the General tab, set the Mode to Modbus Master.
- Still on the General tab, click the Destination Slave IP Mappings button to map the Modbus Slave's IP addresses and their UIDs that the serial Modbus Master will attempt to communicate with.
- For specialized configuration options, select the Advanced tab and configure as required.
Configuring a Slave Gateway
To configure a Slave Gateway (Modbus Master resides on the TCP/Ethernet network), do the following:
- Set the serial port that is connected to the serial Modbus Slave(s) to the Modbus Gateway profile.
- In the Modbus Gateway profile on the General tab, set the Mode to Modbus Slave.
- Still on the General tab, specify the Modbus Slave UIDs that the TCP Modbus Master will attempt to communicate with.
- Still on the General tab, click the Advanced Slave Settings button to configure global Slave Gateway settings.
- For specialized configuration options, select the Advanced tab and configure as required.
Modbus Gateway Settings
The scenarios in this section are used to illustrate how the IOLAN's Modbus Gateway settings are incorporated into a Modbus device environment. Depending on how your Modbus Master or Slave devices are distributed, the IOLAN can act as both a Slave and Master Gateway(s) on a multiport IOLAN or as either a Slave or Master Gateway on a single port IOLAN.
Modbus Master Gateway
The IOLAN acts as a Master Gateway when the Modbus Master is connected to a serial port on the IOLAN. Each Modbus Master can communicate to UIDs 1-247.

Modbus Slave Gateway
The IOLAN acts as a Slave Gateway when the Modbus Master resides on the TCP/Ethernet network and the Modbus Slaves are connected to the serial ports on the IOLAN. Note: The IOLAN provides a single gateway to the network-attached Modbus Masters. This means that all Modbus Slaves attached to the IOLAN's serial ports must have a unique UID. Multiple Masters on the network can communicate with these Modbus Slaves. Note: If a transaction is in progress to a Modbus Slave, other requests to that same device will be queued until that transaction is complete.

Modbus Serial Port Settings
Modbus Master Settings
When the Modbus Masters is attached to the IOLAN's serial port, configure that serial port to the Modbus Gateway profile acting as a Modbus Master. You must configure the Modbus TCP Slaves on the TCP/Ethernet side so the IOLAN can properly route messages, using the Modbus Slave's UIDs, to the appropriate TCP-attached devices.

To configure the Modbus Master on serial port 1, do the following:
- Select the Modbus Gateway profile for serial port 1.
- On the General tab, enable the Modbus Master parameter.
- Click the Destination Slave IP Mappings button and click the Add button in the Destination Slave IP Mappings window.
- Configure the Destination Slave IP Mappings window as follows:

Destination Modbus Slave IP Settings UID: Start: 22 End: 23 Destination Type: Host Gateway IP Address: Start: 10.10.10.11 End: 10.10.10.12 Protocol: TCP UDP UDP/TCP Port: 502 OK CancelThe IOLAN will send a request and expect a response from the Modbus Slave with an IP Address of 10.10.10.11 on Port 502 with UID 22 and from the Modbus Slave with and IP Address of 10.10.10.12 on Port 502 with UID 23 (remember when Type is set to Host, the IOLAN increments the last octet of the IP address for each UID specified in the range).
Modbus Slave Settings
When you have Modbus Slaves on the serial side of the IOLAN, configure the serial port to the Modbus Gateway profile acting as a Modbus Slave. There is only one Slave Gateway in the IOLAN, so all Modbus serial Slaves must be configured uniquely for that one Slave Gateway; all serial Modbus Slaves must have unique UIDs, even if they reside on different serial ports, because they all must be configured to communicate through the one Slave Gateway.

Configuring PPP Dial On Demand
The IOLAN can be configured to access remote networks via modems connected to the serial interface of the IOLAN. By configuring the IOLAN for the Remote Access (PPP) profile, data that is destined for the remote network will initiate a modem connection to the remote network to route the data to its appropriate destination.

I["PPP Local IP Addr: 195.16.20.23\nPPP Remote IP Addr: 195.16.20.24"] --> C
If you want to configure a serial port to use PPP dial on demand, do the following:
- Create an entry for the modem and its initialization string (Serial, Advanced, Modems tab).
- Set the serial port to Remote Access (PPP).
- In Remote Access (PPP), select the Advanced tab. Enable the Connect option and select Dial Out. Set the Modem parameter to the modem you just added. Enter the Phone number that the modem will be calling.
- Still on the Advanced tab, set the Idle Timeout parameter to a value that is not zero (setting this value to zero creates a permanent connection).
- On the General tab, enter one of the following:
• A Local and/or Remote IPv4 Address
• A Local and/or Remote IPv6 Interface Identifier
Note that this IP address or interface identifier should be on its own unique network; that is, not part of the local or remote networks.
In this example, the local network has an IPv4 address of 172.16.0.0/16 and the remote network has an IPv4 address of 204.16.0.0/16, so we arbitrarily assigned the PPP IPv4 Local IP Address as 195.16.20.23 and the PPP IPv4 Remote IP Address as 195.16.20.24.
| IPv4 Local IP Address: | 195 . 16 . 20 . 23 |
| IPv4 Remote IP Address: | 195 . 16 . 20 . 24 |
| IPv4 Subnet Mask: | 255 . 255 . 255 . 0 |
- Next you need to create a gateway and destination route entry. Select Network, Advanced, and the Route List tab.
For the destination, if you want the connection to be able to reach any host in the remote network, set the Type to Network and specify the network IP address and subnet/prefix bits; if you want the connection to go directly to a specific remote host, set the Type to Host and specify the host's IP address.
We want a specific host to the be destination, so we configured the Type as Host:

text_image

The IOLAN can communicate with printers on its serial ports using LPD and RCP protocols, as well as print handling software using TCP/IP.
Remote Printing Using LPD
When setting up a serial line that access a printer using LPD, do the following:
-
Set the serial port to Printer and configure the Speed, Flow Control, Stop Bits, Parity, and Bits parameters so that they match the printer's port settings.
-
Save your settings and restart the serial port.
-
Verify that LPD has been configured on the network host. To configure LPD on the network host, you need to know the name or IP address of the IOLAN and the print queue, either raw_p
for a raw data connection or ascii_p for an ASCII character connection. If you want to direct output to a hunt group, omit the port number(s). For example: raw_p or ascii_p. You can optionally append_d or_f to the queue name to add a or -
To execute a print job on a UNIX Linux system, use the following syntax:
lp -d raw_p
Remote Printing Using RCP
When setting up a serial port that accesses a printer using RCP, do the following:
- Set the serial port to Printer and configure the Speed, Flow Control, Stop Bits, Parity, and Bits parameters so that they match the printer's port settings.
- Save your settings and restart the serial port.
- To execute a print job, use either of the following syntaxes:
rcp <filename> <ip_address>:<line_name>
or
rcp <filename> <IOLAN_Name><line_name>
where <#> is the IOLAN serial port number.
Remote Printing Using Host-Based Print Handling Software
Printers connected to the IOLAN can be accessed by TCP/IP hosts using print handling software.
- Set the serial port to TCP Sockets. Enable the Listen for connection option. On the Hardware tab, configure the Speed, Flow Control, Stop Bits, Parity, and Bits parameters so that they match the printer's port settings.
- Save your settings and restart the serial port.
- The print handling software needs to know the Name of the IOLAN and the TCP Port number assigned to the printer serial port.
Configuring a Virtual Private Network
You can configure the IOLAN to act as a Virtual Private Network (VPN) gateway using the IPsec protocol. Any of the following scenarios can be configured using one IOLAN and a host/server running IPsec software or two IOLANs, each acting as the VPN gateway. All the examples have NAT Traversal (NAT_T) enabled, since both VPN gateways are running through routers.
IOLAN-to-Host/Network
The following example shows how to configure an IPsec tunnel between serial devices connected to the IOLAN and a host/network. NAT Traversal (NAT_T) is enabled in this example (on both sides) because the VPN tunnel is going private network to public network to private network. This example uses an RSA signature for the authentication method, so the steps required to configure the authentication are in this example.

Network-to-Network
The following examples shows how to configure a network-to-network IPsec tunnel. This example uses the X.509 Certificate authentication method, so it includes the configuration requirements for the X.509 certificate. NAT Traversal (NAT_T) is enabled in this example (on both sides) because the VPN tunnel is going private network to public network to private network. Notice also that the serial devices connected to the IOLAN can be accessed by the VPN tunnel, since they are included in the network configuration as part of the 172.16.45.0 subnetwork.

Configuring HTTP Tunnels
Note: When HTTP tunneling is used TCP and UDP ports 50000 and above are reserved and should not be configured by the user.
Serial-to Serial
The following example will demonstrate how to set up a serial device (VT100 Terminal) to serial device (Linux host, console port) connection via an HTTPS tunnel. HTTPS will be used because data security is required. Because IOLAN 1 is behind the firewall, it will need to initiate the HTTP tunnel connection.

Introduction
This chapter describes the parameters that can be passed to the IOLAN when a user logs into the IOLAN (serial port set to profile Terminal) from external authentication RADIUS and TACACS+ servers.
RADIUS
Although RADIUS can be used strictly for external authentication, it can also be used to configure line and user parameters. Therefore, when a user is being authenticated using RADIUS, it is possible that the user's configuration is a compilation of the parameters passed back from RADIUS, the IOLAN parameters if the user has also been set up as a local user in the IOLAN, and the Default User's parameters for any parameters that have not been set by either RADIUS or the user's local configuration.
Supported RADIUS Parameters
This section describes the attributes which will be accepted by the IOLAN from a RADIUS server in response to an successful authentication request.

Mapped RADIUS Parameters to IOLAN Parameters
When authentication is being done by RADIUS, there are several Serial Port and User parameters that can be set by the RADIUS server. Any parameters sent by that RADIUS server that are not supported by the IOLAN are discarded. Below is a list of the RADIUS parameters and their IOLAN parameters:
RADIUS Parameter IOLAN Parameter
Service-Type This has no IOLAN field, although it needs
to be set to Framed-User in the RADIUS
server if the port is set for PPP or SLIP. For
a Console Management profile set the
RADIUS Service-Type to NAS prompt.
Framed-Protocol
Set to SLIP or PPP service.
Framed-Address Remote IP Address field under either SLIP or PPP.
Caution: the exception to the above rule is a Framed-Address value of 255.255.255.254. When this value is specified in the RADIUS file, the unit will use the Remote IP address configured for a PPP line in the IOLAN.
Framed-Netmask
IPv4 Subnet Mask field under either SLIP or PPP.
Framed-Compression
VJ Compression field under either SLIP or PPP.
Framed-MTU
MTU field under SLIP.
MRU field under PPP.
Idle-Timeout
Idle Timeout under the serial port Advanced settings.
Login-Service Corresponds to one
of the following User Service parameters: Telnet, Rlogin, TCP Clear, SSH, or SSL Raw.
Session-Timeout
Session Timeout under the serial port Advanced settings.
Callback-Number
Combination of the Enable Callback and Phone Number fields under User, Advanced settings.
Callback-ID
Combination of the Enable Callback and Phone Number fields under User, Advanced settings.
Perle RADIUS Dictionary Example
The IOLAN has defined Vendor Specific RADIUS attributes in order for the RADIUS server to be configured to support the IOLAN features of Line Access Rights and User Level. These attributes have been defined in Supported RADIUS Parameters on page 399 to allow the RADIUS server to be configured for RADIUS users to have this level of configuration.
See below for an example of the Perle defined attributes for the RADIUS server for a 4-port IOLAN (although the dictionary can contain 48 ports, even if they are not all defined):

TACACS+
Although TACACS+ can be used strictly for external authentication, it can also be used to configure Serial Port and User parameters. Therefore, when a user is being authenticated using TACACS+, it is possible that the user's configuration is a compilation of the parameters passed back from the TACACS+ authentication server, the User's IOLAN parameters if the user has also been set up as a local user in the IOLAN, and the Default User's parameters for any parameters that have not been set by either TACACS+ or the User's local configuration.
User and Serial Port parameters can be passed to the IOLAN after authentication for users accessing the IOLAN from the serial side and users accessing the IOLAN from the Ethernet side connections.

Virtual Modem Initialization Commands
Note: Virtual Modem initialization commands are only supported on IOLAN firmware and configurators version 3.2 or higher.
You can initialize the modem connection using any of the following commands:
| Command | Description Options | |
| ATQn Quiet mode. Determines if result codes will be sent to the connected terminal. Basic results codes are OK, CONNECT, RING, NO CARRIER, and ERROR.Setting quiet mode also suppresses the “RING” message for incoming calls. | n=0, result codes will be sent.(default)n=1, no result codes will be sent. | |
| ATVn Verbose mode. Determines if result codes are displayed as text or numeric values. | n=0, display as numeric values.n=1, display as text. (default) | |
| ATEn Echo mode. Determines whether characters sent from the serial device will be echoed back by the IOLAN when VModem is in “command” mode. Any AT commands not supported will return an “ok” if n=1. | n=0, disable echo.n=1, enable echo. (default) | |
| +++ATH Hang up. This command instructs the IOLAN to terminate the current session and go into “command” mode. | ||
| ATA Answer call. Instructs the VModem to accept connection requests. VModem will give the terminal up to 3 minutes to answer the call. If the ATA is not received within 3 minutes, all pending sync messages will be discarded. | ||
| ATI0 Return the modem manufacturer name. | ||
| ATI3 Return the modem model name. | ||
| ATS0 | Sets the value of the S0 register. The S0 register controls the “auto answer” behavior.In “manual” mode, the IOLAN will not accept incoming sessions until an ATA is issued by the serial device. In “auto answer” mode, the IOLAN will automatically accept an incoming connection request. | Register=0, sets “manual answer” modeRegister=1-255, “auto answer” mode (default) |
| Command | Description | Options |
| AT&Z1 Set com | command allows the user to store an IP address and port number or phone number to use when making a connection. The user will issue an ATDS1 to cause the IOLAN to initiate the connection. | |
| AT&Sn Sets the | behavior of IOLAN's DTR signal. (DSR from a DCE perspective) | n=0, DTR signal always high. (default)n=2, DTR signal acts as DCD.n=3, DTR signal acts as RI. |
| AT&Rn Sets the | behavior of IOLAN's RTS signal. (CTS from a DCE perspective)If line is configured for hardware flow control, the RTS is used for this purpose and the setting of this command is ignored. | n=0, RTS always high. (default).n=3, RTS signal acts as DCD.n=4, RTS signal acts as RI. |
| AT&Cn | Sets the behaviour of the DCD signal. | n=0, DCD always on.n=1, DCD follows state of connection (off when no connection, on when TCP connection exists). (dcftault) |
| AT&F Sets the | modes back to the factory defaults. This is a hard-coded default configuration which does not look at any user configuration. | |
| ATS2 Sets the | value of the S2 register. The S2 register controls which character is used to enter "command" mode. (this is the potential replacement for the +++ (default) in front of the ATH command).This register will hold the hexadecimal value of the "escape" character. Any value > 27 will disable the ability to escape into "command" mode. | |
| ATS12 Sets the | value of the S12 register. The S12 register controls the minimum length of idle time which must elapse between the receipt of the escape character and the A (first character of the ATH sequence). Units are 1/50th of a second. The default is 50 = 1 second. | |
| ATO (ATD with no phone number) Establishes a connection using the IP and port specified in the telephone number field. | ||
| ATDS1 Establishes a connection using the IP and port (or phone number) specified in the Phone Number field (stored by the AT&Z1 command). | ||

Introduction
The IOLAN contains jumpers that you might need to set before you configure it and put it into production. You can set the power out pin, pin 9, to a fixed 5V DC output or to the external adapter output; this can range from 9-30V DC (if an external adapter is shipped with the IOLAN, it has a 12V DC output); maximum output power is 1 (one) watt per a serial port. By default, the power out pin is set to no power. You can set the IOLAN line termination to on or off (this is off by default) if you are using EIA-422/485 (not applicable for I/O models).

Introduction
This chapter provides information on the TruePort and Decoder utilities.
TruePort
TruePort is a com port redirector utility for the IOLAN. It can be run in two modes:
- TruePort Full mode—This mode allows complete device control and operates exactly like a directly connected serial port. It provides a complete COM port interface between the attached serial device and the network.
- TruePort Lite mode—This mode provides a simple raw data interface between the device and the network. Although the port will still operate as a COM port, control signals are ignored. In this mode, the serial communications parameters must be configured on the IOLAN.
You use TruePort when you want to connect extra terminals to a server using the IOLAN rather than a multi-port serial card. TruePort is especially useful when you want to improve data security, as you can enable an SSL/TLS connection between the TruePort host port and the IOLAN. When run on UNIX, TruePort allows you to print directly from a terminal to an attached printer (transparent printing). You can also remap the slow baud rate of your UNIX server to a faster baud rate, as shown below.

B --> C["Ethernet"]
C --> D["Serial Connection\nMap UNIX baud rate 4,800 to 230,400 for faster throughput"]
D --> E["PC"]
Currently, TruePort is supported on Linux, Windows ^® , SCO ^® , Solaris ^® , and others. For a complete list of the supported operating systems, see the Perle website.
For more information, see the TruePort User Guide or the TruePort Installation and Configuration Guide for Windows ^® NT on the CD-ROM.
API I/O Access Over TruePort
You can access IOLAN I/O data through TruePort using the Perle API. The API uses the command/response format. See the ioapiotp.c sample program, found on the product CD-ROM, for an example implementation.
API Request Format
All data in the Request must be sent as a single write to the COM port. The API command takes the following format:
| Number of Bytes Value | |
| 1 Function Code (in hexadecimal): | |
| 01—Get read/write boolean register | |
| 03—Get read/write register | |
| 04—Get read only register | |
| 15—Set read/write boolean register (0x0F) | |
| 16—Set read/write register (0x10) | |
| 2 | Starting register number (seeA4/T4 Registers , A4D2/A4R2 Registers , orD4/D2R2 Registersfor this value). |
| 2 Number of registers to act on starting from the register defined in byte 2 above. | |
| n | Data for write. Some values must be read/written as a unit consisting of 2 consecutive registers. If the request is to write, the data to write follows the number of registers. If accessing registers consisting of 2 bytes or 4 bytes, the data is in big endian (network order) format. |
API Response Format
The API command takes the following response format:
| Number of Bytes Value | |
| 1 Function code of request if no error. Most significant bit will be set if an error occurred. | |
| 1 | Length of data in response if no error occurred. If an error occurred, the byte will contain the error code (see the Error Codes table below). |
| n Data response for request (the number of bytes is dependent on the number and type of registers requested). If the request returns 2 or 4 byte values, it will be in big endian (network order) format. If the request returns boolean values, the least significant bit (bit 0) represents the first value requested and bits 1 to 7 represents subsequent boolean values. If more than 8 boolean registers are requested, they are returned in successive bytes. | |
Error Codes
| Code Name Description | ||
| 01 | Illegal Function | The function code received in the query is not an allowable action for the server (or slave). |
| 02 | Illegal Data Address | The data address received in the query is not an allowable address for the server (or slave). |
| 03 | Illegal Data Value | A value contained in the query data field is not an allowable value for server (or slave). |
| 04 | Slave Device Failure | An unrecoverable error occurred while the server (or slave) was attempting to perform the requested action. |
Decoder
If you are using Port Buffering NFS Encryption, you need to run the Decoder utility to view the port buffering logs. See the Readme file to install the Decoder utility on any of the following operating systems:
- Windows ^® 2000 and greater platform
Note: The Windows/DOS platform restricts the converted readable file to an 8.3 filename limitation.
• DOS
- Solaris x86
• Solaris Spare 32-bit/64-bit
Linux x86 v2.4.x

Introduction
This chapter provides information that can help resolve problems with the IOLAN.
Hardware Troubleshooting
The Power/Ready LED stays red after a boot (See Getting to Know Your IOLAN for the LED label on your IOLAN unit.):
If the IOLAN Power/Ready LED is red and stays red for over 10 seconds, you have a hardware problem that might require factory service. First, try the following:
- If the IOLAN is not in Console mode, do the following:
a. Set up a direct connection to the IOLAN; see Console/Serial Switch for information on this type of connection.
b. Power the IOLAN off.
c. Switch the Console dip switch to On.
d. Power the IOLAN on.
e. Read the messages on the console to determine if the problem can be fixed.
If there is a problem with the IOLAN firmware, you will need to reload the firmware, which can be found either on the CD-ROM that came with the IOLAN or on the Perle website, www.perle.com/downloads (when you access the webpage, select your specific IOLAN model).
- If the IOLAN is already in Console mode and the Power LED stays red, you need to make arrangements to return the IOLAN.
- In Console mode for desktop models or viewing the Console port in rack mount models, see if you need to reload the firmware, which can be found either on the CD-ROM that came with the IOLAN or on the Perle website, www.perle.com/downloads (when you access the webpage, select your specific IOLAN model).
- If the bootloader option does not appear when you reboot the IOLAN (to load new firmware), you need to make arrangements to return the IOLAN.
If you purchased the IOLAN less than 30 days before this problem appears, contact your distributor; otherwise, see the Perle web site (www.Perle.com) for factory service information.
Note: No factory service can be performed on IOLANs that have not been registered.
The Power/Ready LED blinks red (See Communication Issues for the LED label on your IOLAN unit.):
- Good Boot: When the IOLAN cycles through a good boot, the LED blinks for several seconds and then stays a solid green.
- Non-critical Error Boot: When the IOLAN cycles through a boot and a non-critical error occurs, such as a bad port, the LED will blink red briefly before displaying a solid green. You should reboot the IOLAN while monitoring the Console port to view the error information.
- Critical Error Boot: When the IOLAN cycles through a boot and a critical error occurs, such as corrupted firmware, the LED continues to blink red. View the diagnostic information displayed on the terminal connected to the Console port for information on how to correct the problem.
- Fatal Error Boot: When the IOLAN cycles through a boot and a fatal error occurs, the LED stays a solid red).
Communication Issues
General communication checks and practices are as follows:
- Are your cables connected and correctly configured? If you are using EIA-232, see EIA-232 Cabling Diagrams to verify that your cables are correctly configured.
- Can you ping your host? If you can ping but packet loss is reported, ping another host/device on the same network. This will tell you whether the problem is specific to the host/device or general to the network.
- After entering or changing IP information for your IOLAN, reboot the IOLAN (does not apply when using BOOTP or DHCP). Once the IOLAN has rebooted, other network devices should be able to communicate with it (ping, telnet, etc.). Also, protocols such as ARP and proxy-ARP will work properly.
- Use the show routes command (command line only) or view the Routes statistics. Is there a route to the host?
- If the WebManager or DeviceManager cannot communicate with the IOLAN, verify that the Server Services HTTP and/or HTTPS are enabled for WebManager and DeviceManagerD is enabled for DeviceManager. If you are using only HTTPS, the connection URL must start with https://.
DeviceManager Problems
Error Message: 16 bit Windows Subsystem - C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.
The error message can be misleading, because it is displayed even if the AUTOEXEC .NT file is actually missing.
To verify whether you have the file, type %windir%/system32/ in the address bar of an Explorer window. If there is no AUTOEXEC.NT file proceed as follows:
- Browse to %windir%/repair/ (usually C:\WINDOWS\repair).
- Right-click and Copy the AUTOEXEC .NT file.
- Browse to %windir%/system32/ (usually C:\WINDOWS\System32).
- Right-click inside the window and Paste the file.
The error condition described here may also be the result of corruption of the AUTOEXEC . NT file, in which case the above procedure may be helpful to restore a valid file.
If the above procedure does not fix the DeviceManager installation problem, see http://support.microsoft.com/?kbid=324767 for the official Microsoft explanation.
Host Problems
Cannot access a host by name:
- If using DNS or if DNS is required, ensure a nameserver is configured on your IOLAN and is accessible (ping it).
- If not using DNS, verify that the host is configured in the Host Table. Check access to the host by pinging it using the host's IP address.
Cannot access a host on a local network, verify:
• The network address is correct.
- The subnet mask is set correctly and reflects the network configuration.
- The broadcast address is set correctly and reflects the network configuration.
Cannot access a host on a remote network:
- Use the show route command to verify that there is a route to the remote host. If no gateway is specified, verify that a default gateway is specified. Ping the default gateway to check if it is working.
- Consider the situation beyond the gateway; for example, are intermediate gateways and the remote host available? Also, check the messages returned by the ping command; for example, that a particular host or gateway is unreachable.
Gateways added into the gateway table are ignored by the IOLAN:
- Have you used BOOTP and entered a single static gateway in the bootptab file entry? If yes, the other gateways will be ignored.
Access to host lost after a few minutes.
- If the route to this host goes through routers, make sure those routers are all sending RIP packets across the networks.
RADIUS Authentication Problems
User is waiting up to 60 seconds before login is accepted or denied and Authentication is set to RADIUS. User has entered User Name and Password, and has pressed Enter.
- Check RADIUS configuration of primary and secondary authentication/accounting hosts specified, if you have retry and timeout values greater than the default, the IOLAN will be spending time trying each of these hosts and keeping the user waiting.
- Adjust RADIUS configuration: specify just one host, reduce Timeout and Retry values to the default or less than default.
You cannot progress beyond the login and password prompts when authentication is set to RADIUS:
- On the RADIUS host, check the secret (password), you should see it displayed in clear text in the RADIUS clients file. If you are unsure whether it is the same secret which you entered in the IOLAN, go to the IOLAN and re-enter a new secret.
- On the RADIUS host, verify that there is only one entry for a particular user; do not have multiple entries of the same user name (even if the passwords are different).
Login Problems
You cannot obtain a login on any of the serial ports
- Connect via the Admin port and check the settings of the front-mounted ports; they have probably been set to a profile that does support serial connections, such as the Console Management profile (in CLI or Menu, 'direct' or 'silent' telnet/rlogin). Try setting the serial port(s) to the Terminal profile (DSlogin in CLI or Menu).
You have lost or don't know your password (as Admin user).
- You must reset the IOLAN to its factory default settings using the Reset switch on the rear panel. There is no procedure to access the IOLAN without a password.
Problems with Terminals
The following section concerns problems with the appearance of data on your terminal screen.
The IOLAN logs me out after a few minutes:
- Check the Idle Timer value set for the user. The default setting for the Idle Timer for all users is 0 seconds (does not timeout).
Corrupt data.
- Check your line settings (baud rate, stop bits, etc.)
Missing data.
- Verify that the same type of flow control is set in both your terminal and on the IOLAN's port.
Error message not permitted on a dumb terminal after typing the CLI command screen.
- Set your Line to Termtype VT100, ANSI or WYSE60 (or other form of terminal emulation, if you have downloaded one). The default line type in the IOLAN is Dumb, which does not support the graphics characters necessary to view the text-based menus.
Screen corruption when using the text-based menu system.
- Verify that the terminal setup in the IOLAN matches your terminal.
- Verify that entries in the term file match your terminal setup.
- If using a PC/computer, verify that the type of terminal emulation selected in your application matches those supported by the IOLAN.
When using the function keys on your keyboard, nothing happens or your sessions keep swapping.
- Change your Hotkey Prefix character. The function keys on the keyboards of some terminals (like WYSE60) send character sequences which begin with ^a; unfortunately, ^a is also the default Hotkey Prefix, which you use to switch between sessions. A valid alternative would be ^b (hexadecimal=02). If you are the system administrator, you can change any user's Hotkey Prefix character.
When using a downloaded terminal definition, you are having problems using arrow keys.
- Use Ctrl-K, Ctrl-J, Ctrl-H and Ctrl-L for up, down, left and right respectively.
When switching from a session back to the text menus, both screen images are superimposed.
- Press ^r to redraw the screen.
INIT: Error in terminal file
- This error indicates that you have exceeded the 80 character limit for one or more of the terminal capabilities defined in the reported file.
INIT: Error on line n in terminal file
- You have omitted the = sign from the reported line.
Unknown IP Address
You have already configured the IOLAN and you do know your password, and have lost, misconfigured, or don't know the IP address of the IOLAN, so you cannot obtain a successful login.
- If the IOLAN resides within the local network segment, you can use DeviceManager to find the IOLAN.
- You can connect directly to the serial port of the IOLAN, as explained in Using a Direct Serial Connection to Specify an IP Address.
DHCP/BOOTP Problems
Messages: host name too long or filename too long.
- The IOLAN can only accept host names of 14 characters or file names of 64 characters, so verify that you are not attempting to pass a string that is longer than those maximums.
DHCP or BOOTP have been set up to configure my IOLAN, but does not seem to have done anything.
- Check that the server DHCP/BOOTP service is set to on, if not set it to on and reboot.
- Check that your BOOTP server is configured for your IOLAN or that your DHCP server has an active lease pool (scope) with at least 1 free IP address.
You observe TFTP errors when the IOLAN boots, for example:
TFTP: File not found : filename
TFTP: Timed out
This has a number of causes, including:
- The file names you specified to DHCP/BOOTP do not exist or are in the wrong place.
- The server for any of the downloadable files in your bootfile has no TFTP server running.
- Verify that lease data in your DHCP server manager is correct.
- Reset or restart the DHCP server.
Callback Problems
User Callback is On, and a number is configured for the line, but the IOLAN is not calling the user back:
- Verify that the phone number is entered under the user (not the line).
- Verify that the callback Phone Number is valid.
- Verify that the modem at the user's end is set to 'auto-answer'.
Language Problems
In a customized language, the text strings appear in the wrong place in the Menu, CLI, or WebManager.
- Check the original ASCII text file you used to translate to your customised language. The sequence of the line much match exactly (be aware that comments don't affect line sequence, but can affect the actual line that the strings appear on). So, if you strip out all comments, if the original file says line 1000 should be string none, then line 1000 (stripped of comments) should be the translated version of none.
Modem Problems
The IOLAN is not initializing the modem.
- Check your Line Service is set to SLIP or PPP. If your line service is set to any other type, the IOLAN will not initialize a modem. You will need to configure the modem manually.
PPP Problems
The link fails on start-up when there are remote IP addresses set for both a user (Framed IP value) and a line (Remote IP address).
- Check the IP address set for the user; this is used in preference to the IP address set for a line. If there is a problem with the user's IP address, negotiation will fail; the IOLAN will not use the line's IP address as an alternative.
The link fails on start-up and security (either PAP or CHAP) is enabled on the line.
- Check the remote client/device has the same setting; that is, PAP if the IOLAN is using PAP. The IOLAN does not perform negotiation with the remote end over PAP or CHAP.
At the remote end, the client software locks up when security (CHAP) is enabled on the line.
- Disable CHAP re-challenge parameter (challenge_interval) in the IOLAN. Some PPP client software does not work when receiving CHAP re-challenges.
PPP is not running successfully over your 485 half-duplex environment.
- PPP is incompatible with half-duplex; it must be run over a full-duplex environment.
PPP will not authenticate with CHAP and TACACS+.
- Disable MS_CHAP on the client side.
Printing Problems
The print job fails to print on the device attached to the serial port.
- On the line where the printer is attached, set Line Service to Printer. Print jobs will not print when the line service is set incorrectly.
When using RCP, the network host receives a rejection message from the IOLAN. The result is that the print job does not take place.
- Print using LPD
or
- Modify the printer interface scripts on the network host to overcome this weakness of RCP. The modification will force the network host to continue trying to send the print job when the IOLAN's printer port is busy.
Long Reboot Cycle
Rebooting the IOLAN takes a long time.
If you are not using DHCP/BOOTP, disable this within the Server Services; otherwise, the IOLAN waits to timeout for a request to DHCP/BOOTP.
SSL/TLS
If you are experiencing problems obtaining a successful SSL/TLS connection, you can set your Syslog Level to Notice and view the syslog for the following messages:
Line not SSL enabled. Abort connection when a user who is configured for Service SSL_RAW tries to login on the serial port.
The user has been configured for an SSL_RAW connection, but the line has not been configured to enable SSL. To resolve this, either enable the line for SSL or change the user's Service to TCP_CLEAR if SSL is not wanted.
Could not obtain peer's certificate.
- User has selected a cipher key exchange of ADH (anonymous Diffie-Hellman) and enabled Peer verification. ADH does not use certificates so they will not be sent in an SSL/TLS handshake. Disable Peer Verification or change to a cipher suite that uses certificates.
- User has selected Peer Verification on the configured SSL/TLS server and has not configured a certificate for the client. Either disable peer verification on the SSL/TLS server or configure a certificate for the SSL/TLS client.
SSL\_accept failed on the SSL/TLS server device.
- The device has failed to accept an SSL/TLS connection on top of a TCP connection that has just been established. This could indicate that the peer from which TruePort is trying to accept a connection from is not configured for SSL/TLS. Verify that the peer has been configured for an SSL/TLS client connection.
Certificate did not match configuration
- The message is displayed when Validate Peer Certificate has been enabled, but the configured Validation Criteria does not match the corresponding data in the certificate received from the peer. The data configured must match exactly to the data in the certificate. The data is also case sensitive.
unknown protocol message when trying to make an SSL/TLS connection
- This will be displayed when both sides of the TCP connection are configured as SSL/TLS clients. Change one of the end points to act as an SSL/TLS server.
- One of the endpoints is not configured for SSL/TLS. Make sure both endpoints are configured for SSL/TLS, verify that one is a client and the other is a server.
tlsv1 alert handshake failure or sslv3 alert handshake failure
- The remote site has an SSL/TLS error and is sending this message with an alert message. Look at the error messages on the remote end and fix the problem indicated.
I/O Models
An I/O Digital or Relay controlled motor is starting/stopping
- Digital and Relay channels have automatically resetting fuses, meaning that if the circuit gets overloaded and the fuse blows, it will automatically reset when the circuit cools down.
An A4R2 model is starting/stopping
- The A4R2 model can run at 55 degrees Celsius ambient temperature when the input voltage is 22VDC or below. If the input voltage exceeds 22VDC, the maximum ambient temperature will drop into the range of 45-50 degrees Celsius to run successfully.
IPv6 Issues
You are not seeing the IPv6 address value when you attempt to connect to the IOLAN.
Many Windows ^® based systems have IPv6 support already enabled, however, if you need to install IPv6 then follow the procedure below.
To install IPv6 support do the following:
- In Control Panel, double-click the Network Connections icon.
- Double-click the Local Area Connection entry.
- In the Local Area Connection Status window, click the Properties button on the General tab.
- In the Local Area Connections window, click the Install button on the General tab.
- In the Select Network Component Type window, select Protocol and click the Add button.
- In the Select Network Protocol window, select Microsoft TCP/IP version 6 and click the OK button.

Introduction
This appendix provides additional information about the Modbus Remapping feature.
Modbus Remapping Feature
The Modbus remapping feature allows a TCP Modbus Master to poll a Modbus slave device and have the IOLAN translate the UID to a different UID for the slave device. The Master UID has to be unique on the IOLAN. The Slave UID must be unique on each serial port. The translate rules are controlled by a file downloaded to the IOLAN.
The following procedure will allow you to use the Modbus remapping feature:
Create a configuration file
- The file must be called "modbus_remap"
• One translate rule per line - The fields on a line are separated by a comma
Line format for one UID is:
port, master_uid, slave_uid
- port: is the IOLAN port number that the slave is connected to
- master_uid: is the UID that the TCP Modbus Master uses
- slave_uid: is the UID that the Modbus slave uses
Line format for UID ranges is:
port, master_start-master_end, slave_start-slave_end
- port: is the IOLAN port number that the slave is connected to
- master_start: is the first master UID in the range
- master_end: is the last master UID in the range
- slave_start: is the first slave UID in the range
- slave_end: is the last slave UID in the range
Configuring the Modbus UID Translation Feature
-
On the serial port Modbus Gateway, configure Modbus slave. Configuration parameters such as "UID range" and UID Address Mode will be ignored in this mode of operation
-
Down load the "modbus_remap" file that you created to the IOLAN using:
● Device Manager: use "tools-advanced-custom files" dialog "download other file"
Web Manager: use "administration-custom files" page "other file"
- CLI: use the command "netload customapp-file" command

Symmetric Key File
This section defines the layout of the NTP/SNTP Symmetric Key file that must be downloaded to the IOLAN in order to use NTP/SNTP server authentication feature. Each line of the NTP/SNTP symmetric key file consists of three fields: a key ID in the range 1 to 65,534, inclusive, a key type and a message digest key consisting of a printable ASCII string equal to or less than 20 characters or a 40 character hex digit string.
| key ID key type | message digest key | ||

Modem not connecting to the network.
This appendix provides some helpful troubleshooting tips for getting your USB modem to connect to your wireless network.
In most cases, the IOLAN will be able to detect, initialize and operate the USB modem automatically. The pre-requisites for successfully connecting your USB modem to your service provider's network are an installed Perle USB option card that is configured with the service provider's APN, phone number (normally *99#), optional username, password and PIN#/SIM lock code. Refer to Configuring a USB Modem.
After configuring the USB option card and USB modem settings, you must save the configuration and either reboot the IOLAN or kill the PCI line service (the last serial line service) for the settings to take effect. Successful connection to the wireless network can take up to 2 minutes. Most USB modems have LEDs indicating the connection status. A solid green or blue LED on your USB modem usually indicate a successful wireless connection. If the connection is not established after this time, please try the following:
1) Connect a terminal to the IOLAN using the console port and cable.
2) Login as admin
3) Issue the CLI command "usb show modem"
Depending on the various stages of trying to connect to the wireless network, you may see the following responses on your terminal. While the responses are mostly self-explanatory, the instructions below will suggest an action to take.
Output:
"USB modem feature is not supported on this hardware."
Action:
This feature is only valid on the IOLAN SCS models. Acquire IOLAN with option card slot and Perle USB option card.
Output:
"USB option card was not configured. Please select, configure and save the configuration for the USB option card and retry this command."
Action:
The usb option card and modem has not been configured. See Configuring a USB Modem
Output:
"No USB modem device detected. Please connect a USB modem to one
of the USB ports."
Action:
The software is not detecting a USB modem in the USB port. If one is inserted, please make sure that it is properly seated in the USB connector.
Output:
Manufacturer: manufacturer name
Product: product name

"USB modem appears to be functioning normally. If connection problems persist, please review your USB modem configuration (APN, PIN #, PHONE #)."
Action:
As far as the driver can tell, the USB modem is functioning correctly. At this point, if you are not able to establish a connection with the network, the source of the problem could be the usb modem configuration. Check your configuration parameters and ensure it matches the information given to you by the network provider. See Configuring a USB Modem

"USB modem appears to be functioning normally. If connection problems persist, please review your USB modem configuration (APN, PIN #, PHONE #)."
Action:
As far as the driver can tell, the USB modem is functioning correctly. If there is no wireless network connectivity, verify the APN, phone number and optional PIN#, user and password settings. Each service provider's network will have different requirements. See Configuring a USB Modem.
If this does not resolve the problem, use the Vendor id and product id to search the linux community for any problems with this particular device. If the recommendation is to use a device name override, use the "usb create modem-file devname ttyUSBn" (n = 1 to 4) to create the override option. Please remember to save your changes and either reset the PCI option line service or reboot the IOLAN, in order for the changes to take effect.
USB Modem Support and Custom Options
While we strive to include support for as wide a range of USB modems as possible, our support for USB modems is currently limited to the Communication Device Class Abstract Control Model interface (dev/ttyACMx device node), and the USB Serial Converter support for generic GSM and CDMA modems interface (dev/ttyUSBx device node). The IOLAN attempts to initialize the USB modem assuming the CDC-ACM type device, and after 30 seconds and multiple retries, it will try to initialize using the USB serial converter generic GSM/CDMA method. This latter method, requires a USB communication utility called "usb_modeswitch" that has a database of USB modems of this class. Should you have a USB modem that is not in our database, but is available by way of the linux internet community, please follow instruction below on how to download the file to the IOLAN. or contact Perle support for assistance.
There are also USB modems that require that a different device node be used other than the default /dev/ttyUSB0 device nodes. If after validating your USB modem configuration, you still do not have wireless connectivity, you may need to search through the Linux community using your USB modem's vendor id and product id, to determine if an override for the device node is required. The "usb modem status" command will output the information you need to do the search for connectivity issues in the linux community. To override the default device name, please use the following command:
usb create modem-file devname ttyUSBn (where n is an interface number between 1 - 4)
Should you find it necessary to remove the devname override, please use the "usb delete modem-file" command. This command will also remove any custom, downloaded usb_modem and modeswitch files (see next section).
Downloading Custom USB Modem Configuration Files
If you have a usb_modeswitch file which you have found for your USB modem and this modem is not currently in the IOLAN database, you can download the file as follows;
1) Connect a terminal to the IOLAN using the console port and cable.
2) Login as admin
3) Issue the following CLI command;
netload customapp-file <ip_address> <filename>
ip_address is the address of your tftp server
filename is the usb_modeswitch file full path and name
This will transfer the usb_modeswitch file from your TFTP server to the IOLAN. The file name is in the format "vvvv:pppp" where;
vvvv = Vendor ID
pppp = Storage Product ID
At this point, you can either re-boot the IOLAN or kill the PCI port to re-try the USB modem.

| This chapter provides definitions for Device Server terms. | |
| BOOTP (BOOTstrap Protocol) | An Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive. |
| Callback | A security feature where the Device Server calls back the User at a predetermined number defined in the User's account. |
| CHAP (Challenge Handshake Authentication Protocol) | Standard authentication protocol for PPP connections. It provides a higher level of security than PAP and should be used whenever possible. see PAP |
| Community (SNMP) | An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where information is sent. |
| DHCP (Dynamic Host Configuration Protocol) | A TCP/IP protocol that provides static and dynamic address allocation and management. |
| Direct Connection | Connections that bypass the Device Server enabling the user to log straight into a specific host. A direct connection is recommended where a user logging in to the Device Server is not required. |
| Ethernet | A high-speed (10Mbps,100Mbps) cable technology that connects devices to a LAN, using one or more sets of communication protocols. |
| Fixed Callback | A method where there is a specific number defined to callback a user. |
| Local Authentication | Uses the user ID and password stored within the Device Server User database. |
| LPD | Line Printer Daemon. A printer protocol that uses TCP/IP to establish connections between printers and workstations on a network. The technology was developed originally for BSD UNIX and has since become the de facto cross-platform printing protocol. |
| Modem Initialization String | A series of commands sent to the modem by a communications program at start up. These commands tell a modem how to set itself up in order to communicate easily with another modem. |
| MOTD | Message of the day. This is defined by a file whose contents display when users log into the Device Server. |
| Multicast | The broadcasting of messages to a specified group of workstations on a LAN, WAN, or internet. |
| NAK (Negative Acknowledgment) | A communication control character sent by the receiving destination indicating that the last message was not received correctly. |
| PAP (Password Authentication Protocol) | Standard authentication protocol for PPP connections. see CHAP |
| RADIUS (Remote Authentication Dial In Users Services) | An open standard network security server that communicates with the PAP protocol. |
| Reverse Connection | Connections that originate from a host that go directly to a serial device through the Device Server. |
| RIP (Routing Information Protocol) | A protocol that allows gateways and hosts to exchange information about various routes to different networks. |
| Roaming Callback | A method where the client supplies the number for callback when they dial in. |
| RPC | Remote Procedure Call. A type of protocol that allows a program on one computer to execute a program on a server computer. |
| Silent Connection | Silent connections are the same as direct connections except that they are permanently established. The host login prompt is displayed on the screen. Logging out redisplays this prompt. Silent connections, unlike direct connections, however, make permanent use of pseudo tty resources and therefore consume host resources even when not in use. |
| SNMP (Simple Network Management Protocol) | A protocol for managing network devices. |
| Subnet/Prefix Bits | Identifies the device's IP address, which portion constitutes the network address and which portion constitutes the host address. |
