Frequently Asked Questions - AdderLink iPEPS Adder

How do I connect the AdderLink iPEPS to my computer?

Connect the supplied KVM cable between the iPEPS and the computer's keyboard, video, and mouse ports. For USB connections, use the included USB converters (green for keyboard/mouse signals). The iPEPS must be connected to a network via its Ethernet port.

How can I reset the iPEPS to factory default network settings?

Power off the unit. Set switch 2 on the side to ON. Power on, wait for the VNC indicator to light, then press the reset button (small hole near power socket). After the VNC light flashes five times, power off and return switch 2 to OFF.

What should I do if the remote mouse cursor is not synchronized?

Click the 'Resync Mouse' button in the viewer toolbar or use the 'Controls' menu to recalibrate. Ensure the host screen is static and clear of windows in the top-left corner. You may also need to select the correct mouse type (PS/2 or IntelliMouse) via the Restore Mouse Functions option.

Can I use encryption when connecting remotely?

Yes. The iPEPS supports 128-bit encryption. In the viewer, set encryption to 'Always On' or 'Let Server Choose'. The iPEPS must be configured for encryption (Always, Prefer On, or Prefer Off) in the unit configuration menu.

What are the default hotkeys for the local menu?

The default combination is Ctrl + Alt + C to access the local control menu. This can be changed in the unit configuration settings.

How do I transfer files to the host computer using Virtual Media?

First, ensure the iPEPS is connected to the host via USB. Then, in the VNC viewer, press F8 then V to select a drive or file. Alternatively, use the Controls menu > Virtual Media. The host will see the transferred files as a removable disk.

Which web browsers are supported for remote access?

Windows: Internet Explorer 5.50+ with Microsoft Java VM 5.50 or Java Runtime 1.3+. Linux: Netscape 4.61+, Opera, with Java Runtime 1.1+.

How many users can access the iPEPS simultaneously?

Up to five users total: one local user (Dual Access model only) and four remote users via VNC or web browser. Access can be shared (all see same screen) or private.

Can I power the iPEPS without an external adapter?

Yes. The iPEPS can draw power from the keyboard and mouse connections to the host computer. Both connections must be made; the unit will refuse to operate if only one is connected. For higher loads, use an external 5V DC adapter.

How do I change the IP address if I don't know the current one?

Use the USB configuration method: set switch 2 to ON, connect the mouse port to a PC via USB (using the green converter). The PC will see a new disk. Edit the 'config.txt' file to set the desired IP address, then safely eject the disk. Power off and return switch 2 to OFF.

Introduction

Drawing upon our long and successful history within the field of remote system control, we have taken our best KVM via IP technology and miniaturised it. The result is the AdderLink iPEPS, a highly responsive, cost efficient way to control a single system from any remote position - worldwide.

iPEPS stands for 'iP Engine Per Server' and gives an indication of the clear design goals that have been applied to this product since its conception. In situations where a single system must be placed in a relatively isolated location and yet must be controlled from elsewhere, then iPEPS is the solution. The host system can run its usual operating system completely unchanged and needs only to be connected (via its keyboard, video and mouse ports) to the compact iPEPS unit. This ensures that there is no performance hit associated with other remote solutions and also provides the authorised remote user with complete control. The remote user uses a compact VNC viewer utility and can link to the iPEPS via any connected IP network, or via the Internet.

Where local control is also required, either temporarily or permanently, the iPEPS Dual Access variant provides the necessary local connections for keyboard, monitor and mouse.

Adder Virtual Media feature

Allows an authorised remote user to transfer files and folders to a host computer, such that they appear as though presented locally on removable media (as would a memory stick, CD-ROM or floppy). Via the IP network link, the remote user can then control the host and make use of the transferred files and folders. An indispensable feature when remotely upgrading or patching distant host systems.

USB adapters

Every iPEPS module is supplied with special PS/2 to USB adapters. These not only convert the connector types but also permit the use of the Virtual Media feature on USB equipped systems.

AdderLink iPEPS features

There are two types of AdderLink iPEPS units: the dual access model which allows a local keyboard, video monitor and mouse to be situated next to the computer and a standard model which eschews such connections to achieve a thinner casing. The dual access model measures 118 x 75 x 42mm, whereas the standard model measures just 118 x 75 x 26mm.

KVM console

(Dual Access model only) Optionally connect a keyboard, video monitor and a mouse to these three connectors to allow local control of the system.

Close-up of a gray electronic device with ports and connectors (no readable text or symbols)

Connections to computer

Link these connectors to the keyboard, video and mouse ports of the computer system to be remotely controlled.

Non Dual Access model

The standard iPEPS module lacks the connectors to attach a local keyboard, video monitor and mouse, resulting in a slimmer casing.

IP network port

This intelligent Ethernet port can automatically sense whether it is attached to a 10Mb or 100Mb network.

Indicators

These six indicators clearly show the key aspects of operation:

• LNK Network link and activity indication.
• REM Keyboard or mouse data are being received from a remote viewer.
  • VNC Indicates that a remote viewer is connected and active.

• 100 Indicates the Ethernet network speed (10/100Mbs).

- LOC Keyboard or mouse data are being received from the local console (or the USB Configuration Disk feature is in use).

• PWR Power indicator.

Installation

Mounting

The iPEPS offers two main mounting methods:

• Supplied four self-adhesive rubber feet
- Rack mount brackets - see below

Connections

An extra width rack bracket is available as an optional extra for the iPEPS Dual Access model.
A rack bracket is supplied with each iPEPS standard model.

Connections

Installation of the iPEPS involves a number of basic connections to some or all of the following items:

• Host computer (below)
• Local keyboard, video and mouse
  • IP network port
  • Power supply

Host computer

The iPEPS is connected to the host computer using the supplied KVM cable. At the computer end of the cable you have the choice of linking the cable's PS/2 connectors directly to the computer or additionally attaching the supplied USB converters. The converters not only allow you to use the computer's USB sockets but also enable the Adder Virtual Media feature to be used.

To attach the KVM cable to the iPEPS

1 Ensure that power is disconnected from the iPEPS and the computer.

(Note: If it is not possible to switch off the computer prior to connection, then a 'Hot plug' procedure is available – see the Hot plugging and mouse restoration section for more details).

2 Connect the plugs at one end of the KVM cable set to the three sockets at one end of the iPEPS. On the Dual Access model these are the ones on the bottom row.

To attach the KVM cable to the computer

1 Connect the video connector of the KVM cable to the video output socket of the computer.
2 The keyboard and mouse connections can be made to the computer in two main ways:

- Directly to PS/2-style keyboard and mouse sockets of the computer.

or

• Via the supplied converters, to the USB connectors of the computer.

When used in this way, the keyboard and mouse signals are both fed via the green USB converter (and lead).

Note: If you intend to power the iPEPS from the keyboard/mouse interface (rather than a power adapter) both the purple and the green connections must be made to the computer. This is true regardless of whether you use the PS/2 connections or the USB converters. The iPEPS will prevent power being taken from just one socket in order to prevent overloading.

Local keyboard, video monitor and mouse

Note: Dual Access model only

Where local control is required (as well as remote control), the iPEPS Dual Access model provides the necessary keyboard, video and mouse console outputs.

To connect a local keyboard, video monitor and mouse

1 Position a suitable keyboard, video monitor and mouse in the vicinity of the iPEPS such that their cables will easily reach.
2 Connect the keyboard, video monitor and mouse plugs to the sockets, collectively labelled as 'KVM CONSOLE', on the end panel of the iPEPS.

IP network port

The iPEPS provides an autosensing Ethernet IP port that can operate at 10 or 100Mbps, according to the network speed. The iPEPS is designed to reside quite easily at any part of your network:

• It can be placed within the local network, behind any firewall/router connections to the Internet, or
• It can be placed externally to the local network, on a separate sub-network or with an open Internet connection.

Wherever in the network the iPEPS is situated, you will need to determine certain configuration issues such as address allocation and/or firewall adjustment to allow correct operation. Please refer to Networking issues within the Configuration chapter for more details.

IMPORTANT: When the iPEPS is accessible from the public Internet, you must ensure that sufficient security measures are employed.

To connect the IP network port

1 Depending upon where in the network the iPEPS is being connected, run a category 5e or 6 cable from the appropriate hub or router to the iPEPS.
2 Connect the plug of the category 5e or 6 cable into the IP port on the end panel of the iPEPS.

3 Configure the network settings as appropriate to the position of the iPEPS within the network - see Networking issues for details.

Power supply connection

The iPEPS provides flexibility in the way that it is powered in order to suit your installation requirements. Each iPEPS can be powered:

• Via the keyboard and mouse connections from the host computer,
• From an individual power adapter, or
• From a common power adapter (when used with other iPEPS units).

Power supply issues and options

If you intend to derive power from the keyboard and mouse connections, then both connections must be made to the host computer. The power requirement of the iPEPS slightly exceeds the maximum that is permissible via a single keyboard, mouse or USB port. Therefore, the iPEPS will share its requirements between two ports and will automatically refuse to operate if only one connection is made.

The iPEPS draws a maximum current of 1A at 5VDC. If your computer cannot provide the necessary power requirement (via its keyboard, mouse or USB ports) then you will need to use an external power adapter and also prevent the iPEPS from deriving any of its power from the ports. On the side panel of the iPEPS, use switch 1 to determine how power should be derived:

SW1 OFF Derive iPEPS power from either the interface connections or an external power supply.

ON Derive iPEPS power only from the external power adapter.

To connect the optional power adapter

1 Connect the low voltage output connector from the power supply unit to the power socket on the end panel of the iPEPS. Note: Ensure that switch 1 is set to the appropriate setting for your installation - see 'Power supply issues and options' opposite.

2 Connect the IEC connector of the supplied country-specific power lead to the socket of the power supply.
3 Connect the power lead to a nearby mains supply socket.

continued

To use a common power adapter to supply multiple iPEPS units

Available as an optional item, the Adder Power Squid cable allows you to distribute power from an adapter to a maximum of four iPEPS units.

Note: Do not attempt to power more than two iPEPS units using the standard 5V 2A power adapter unit. For three or four iPEPS, use only the higher capacity 5V 4A adapter.

1 Connect a power output plug of the squid cable to the input socket of each iPEPS unit.
Note: Ensure that switch 1 on each iPEPS is set to the appropriate setting for your installation - see Power supply issues and options on the previous page.
2 Connect the low voltage output connector from the power supply unit to the input socket of the power spider cable.
3 Connect the IEC connector of the supplied country-specific power lead to the socket of the power supply.
4 Connect the power lead to a nearby mains supply socket.

Configuration

Initial configuration

The iPEPS initial configuration process occurs as two distinct parts. The standard iPEPS and the Dual Access models differ in Part 1 of their configuration, but behave in an identical manner for the Part 2 configuration.

Part 1 – Initial configuration

This part of the configuration takes place using either a locally connected keyboard and video monitor (Dual Access model only) or a computer connected to the same local network as the iPEPS. It allows you to set up key basic details, network essentials and security key creation.

Part 1 - Initial configuration (Dual Access model)

When controlled via the locally connected keyboard and video monitor, as the iPEPS Dual Access model is switched on for the first time it will take you through a set up sequence consisting of three main screens:

OR

Part 2 - Remote configuration

This part of the configuration takes place using a remote network connection. It allows fine tuning of the part 1 configuration items plus the creation of multiple user accounts. Go to Part 2 - Remote configuration.

Part 1 – Initial configuration (Standard or Dual Access models)

Connect the iPEPS to an IP network and use a computer located on the same network to connect to the iPEPS. See page 16 for details.

Unit config screen

Allows you to determine a mixture of basic and fundamental setup details such as the keyboard layout, admin password, time and date.

Network config screen

Requires you to configure the various key aspects of the IP network port addressing.

Secure keys screen

This screen uses your mouse movements or keyboard inputs to create random data. This unpredictable information is then combined with several other factors to develop the basis of the encryption keys that are used to establish secure remote links.

continued

Controlling the local configuration menus

The local menus use only the keyboard. Use the keyboard arrow keys to move the green highlight indicator to the required position. Then, either type the required information or use the left and right arrows to change multiple choice items, as appropriate.

Problems?

The iPEPS asks for an unknown admin password

Part 1 - Initial configuration (Dual Access model)

To perform the initial local configuration (Dual Access model only)

1 Edit the Unit config screen. The key elements here are:

Admin password

Enter a password of at least 8 characters, including at least 1 letter, 1 number and a special character. The background colour provides an indication of password suitability and is initially red to indicate that the password is not sufficient. When a password with reasonable strength has been entered it changes to blue.

Time and Date

Set these correctly as all entries in the activity log are time stamped using them.

Encryption

Arrange this setting according to your security requirements. See Encryption settings for a description of the issues and the settings.

When all items are correct, select the Next option to display the next screen.

2 Edit the Network config screen. The key elements here are:

Use DHCP/IP address/Net Mask/Gateway

You need to either set the DHCP option to 'Yes' or manually enter a valid IP address, Net mask and Gateway. See Networking issues for more details.

VNC and HTTP ports

These should remain set to 5900 and 80, respectively, unless they clash with an existing setup within the network. See Networking issues for more details.

When all items are correct, select the Next option to display the next screen.

3 Move the mouse and enter changing key sequences within this screen.

With every mouse move and keypress, the single dash will move across the screen (unless the same key is pressed repeatedly). Periodically, a new star character will be added to the bar as the random data are accepted as part of the new encryption key. When the bar is full, the final encryption keys for your iPEPS will be created – this process takes roughly 30 to 40 seconds.

4 Once the secure keys have been calculated the iPEPS will restart and present a standard logon screen.

At this stage the username will be 'admin' and the password will be whatever you entered in the first setup screen.

Once the username and password have been accepted, the screen should now show the host computer screen (or, if none is connected, a blank image).

continued

5 To view the options menu: Press Ctrl Alt C. More about hotkeys. (if the standard hotkeys were altered, use the new hotkeys plus C)

Access mode

Allows you to choose between Shared mode (where all other logged on users can see your operations) and Private mode (where the screens of all other users are blanked).

Logoff

Select to close your current session and display the screensaver.

Restore mouse functions

Select to revive a mouse that has ceased to function correctly. See Hot plugging and mouse restoration for details.

Configuration

Select to gain access to the Unit and Network configuration screens. Within here you can also reset the iPEPS to its initial state.

Return to host

Quits the menu and returns to the host screen.

Encryption settings

The iPEPS offers a great deal of flexibility in its configuration and this extends equally to its encryption settings. Due to the variety of situations in which it might be used and the range of viewer applications that need to view it, a number of settings are available that might not make perfect sense at first glance. However, these settings should allow you to configure the iPEPS and the viewers to operate as required.

Factors to consider when setting these options might be:

• Do all of the connections and operations require encryption?
• Will some users be using older VNC viewer versions?

iPEPS encryption settings

The iPEPS configuration page offers three encryption settings:

• Always on - This setting will force all viewers to use encryption. Note: This setting will preclude any VNC viewer versions that do not support encryption.

- Prefer off - This setting does not enforce encryption unless a viewer specifically requests it. If a viewer has its 'Let server choose' setting, then an un-encrypted link will be set up.

- Prefer on - This setting generally enforces encryption unless an earlier viewer version is unable to support it, in which case the link will be unencrypted. If a viewer has its 'Let server choose' setting, then the link will be encrypted.

Viewer encryption settings

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four encryption settings:

• Always on - This setting will ensure that the link is encrypted, regardless of the iPEPS encryption setting.
• Let server choose - This setting will follow the configuration of the iPEPS. If the iPEPS has 'Always on' or 'Prefer on' set, then the link will be encrypted. If the 'Prefer off' setting is selected at the iPEPS, then the link will not be encrypted.
• Prefer off - This setting will configure an un-encrypted link if the iPEPS will allow it, otherwise it will be encrypted.
• Prefer on - If the iPEPS allows it, this setting will configure an encrypted link, otherwise it will be un-encrypted.

Hot plugging and mouse restoration

It is strongly recommended that you switch off the host computer before attempting to connect it to the iPEPS. However, if this is not possible then you need to 'hot plug' the computer while it is still running. There is not normally a danger of damage to the computer, however, when mouse communications are interrupted, often they fail to re-initialise when reconnected. The iPEPS provides a feature to reinstate mouse communications once the necessary connections have been made.

There are two main types of data formats used by current PC mice, these are the older 'PS/2' format and the more recent 'IntelliMouse®' format introduced by Microsoft. These use slightly different data arrangements and it is important to know which type was being used before you hot-plugged the computer to the iPEPS. The previous setting depends both on the type of mouse and the type of driver, as various combinations of PS/2 and IntelliMouse are possible. Using the incorrect restore function may produce unpredictable results and require the computer to be re-booted.

Which restore setting do I use?

The general rule is that unless both the mouse and the driver are both IntelliMouse compatible then you need to restore the mouse as 'PS/2'. An IntelliMouse can operate in either mode, whereas a PS/2 mouse cannot.

Recognising an IntelliMouse-style mouse

The IntelliMouse format was introduced to support, among other features, the scroll wheel function. If the mouse has a scroll wheel, then it is likely to support the IntelliMouse format. If it is a Microsoft-branded mouse, then it will usually state that it is an IntelliMouse on its underside label.

Recognising an IntelliMouse driver

Before hot plugging to the iPEPS (or afterwards using only keyboard control), access the Windows Control Panel of the computer and select either the Mouse option (on Windows NT, 2000 and XP) or the System option (on Windows 95, 98, ME). Look for the name of the driver, which will usually include the words PS12 or IntelliMouse.

To restore mouse operation when hot plugging:

1 Carefully make the keyboard, monitor and mouse connections between the host computer and the iPEPS ports.
2 Using a keyboard and monitor directly connected to the iPEPS, log on and then press CM Alt C to view the options menu. More about hotkeys
3 Select the 'Restore mouse functions' option to display:

4 Select one of the following options:

• Restore PS/2 Mouse – if PS/2 mode is required, or
• Restore IntelliMouse – if IntelliMouse mode is required.

5 Select the 'Return to host' option.

6 Move the mouse a short distance and check for appropriate on-screen cursor movement. If the mouse cursor darts erratically around the screen, then cease moving the mouse. This is an indication that the chosen restore function is incorrect. Try again using the other restore function.

Note: The restore functions predict the likely mouse resolution settings but may not restore the exact speed or sensitivity settings that were originally set.

Resetting the configuration (Dual Access models only)

The iPEPS does not display the configuration sequence

If the iPEPS has been previously configured it may not automatically display the first of the setup screens. In this case you have two options, either:

• Access the Unit or Network configuration screens separately, or
• Reset the configuration:

To invoke a configuration reset by main menu

1 Using the locally connected keyboard and screen, log on as the admin user.
2 Select the 'Configuration' option.

3 Highlight the 'Reset configuration' option and press

A warning screen will be displayed, select the RESET option and press

4 The iPEPS will reset and then display the first of the four initial configuration screens.

Part 1 – Initial configuration (Standard or Dual Access models)

To perform the initial local configuration

1 Connect the iPEPS to an IP network where a suitable computer is available on the same subnet (please see the Installation chapter for further details).

2 Use a computer connected to the same subnet of the network. On that computer, locate and select the VNC viewer icon A connection details dialog will be displayed:

VNC Viewer

3 In the 'Server:' entry, type the address: 192.168.1.42
4 Click the OK button. Depending on the options selected, you may need to confirm certain items. A connection attempt will be made and if successful, an authentication dialog will be displayed:

5 Enter admin as the Username, leave the password entry blank and click the OK button. You will now be prompted to enter a new password before the Viewer window opens:

If the iPEPS does not respond, then please see the next page for details of actions that you can take.

6 Click the Configure button to display the Configuration menu:

You are now ready to begin Part 2 of the configuration. Use the various options (particularly the 'Unit Configuration' and 'Network Configuration' options) to arrange the iPEPS to suit your requirements.

If the iPEPS does not respond on the network

If the iPEPS fails to respond when you attempt to access it on a local network (as discussed on the previous page), the most likely cause (presuming that it is correctly connected) is that it has been re-assigned to use network settings other than the default values.

In such cases, you can remedy the situation in either of two ways, either:

- Reset the iPEPS back to its default network settings using the reset procedure (shown below),

or

- Set the iPEPS to any required network settings using a USB link (shown right) ➕.

To reset the iPEPS to its default network settings

If the iPEPS network address has been previously changed from its factory default, then it won't respond when you try to make initial contact. You can reset it to its default address (192.168.1.42) and other settings by performing the following:

1 Remove all power to the device.

2 Set switch 2 on the side of the unit to its ON position.

3 Apply power to the device. After about two seconds the VNC indicator will light. Before the indicator extinguishes, insert a thin object (such as a straightened paperclip) into the small hole adjacent to the power socket to depress the concealed reset switch and then remove it.

4 Shortly after, the VNC light should flash five times. This indicates that the reset operation has been successful.

5 Remove power and return switch 2 on the side of the unit to its OFF position.

To alter the iPEPS network settings via USB connection

This method allows you to configure the basic iPEPS network settings before it has been connected to any network. To achieve this task, you need to connect the iPEPS to a computer that uses Windows 2000, XP or Vista.

1 Remove all power to the device and set switch 2 on the iPEPS unit to 'ON'.
2 Connect the iPEPS mouse port to a vacant USB socket on your computer using the supplied KVM cable and green USB converter plug as shown in the Host Computer connections section. Note: If you also connect the keyboard cable and purple converter then the iPEPS can derive power from the computer.
3 Power up the iPEPS unit and the computer (if not already switched on).
4 The Windows computer should report that a 'New Disk' has been inserted. Use Windows Explorer to browse to the new disk and locate the file 'config.txt'. Edit this file using an editor such as Notepad or Wordpad:

5 Edit the parameters in this file as required, then save the file.
6 IMPORTANT: In the Windows Explorer 'File' menu, choose the 'Eject' option in order to prompt the iPEPS to use the new information. Wait a couple of seconds to ensure that this action has been completed.
7 Disconnect the USB cable from the computer.
8 Wait for ten seconds and then power down the unit.
9 Return Switch 2 to its 'OFF' position.
10 The iPEPS unit configuration should have been set with the new information that you provided in the config.txt file. If necessary, you can confirm that this has happened by repeating these steps to check the contents of the "config.txt" file.

Part 2 - Remote configuration

The second part of the configuration requires you to log into the iPEPS from a system via a network connection using either of the following two access applications:

• The VNC viewer – a small application downloadable from the Adder and RealVNC websites or even downloadable from the iPEPS itself.
  or
• A standard browser that supports Java – As soon as a web browser makes contact, the iPEPS downloads a Java application to it. This allows a viewer window to be opened and operation to commence just as it would with the VNC viewer application.

User accounts Allows you to create and manage up to sixteen separate user accounts, each with separate access permissions.

Unit configuration

Allows you to alter both basic and fundamental

settings within the iPEPS.

Time & Date Configuration

Allows you to set the current time and date as well as the timezone specifier and specify a network timeserver, if necessary

Network configuration

Here you can alter any of the existing network settings plus you can take advantage of the IP access control feature that lets you to specifically include or exclude certain addresses or networks.

Logging and status

Provides various details about the user activity on the iPEPS.

To perform the remote configuration

1 Use either the VNC viewer or a standard web browser to make remote contact with the iPEPS – see Connecting to the iPEPS for more details.
2 If the username entry is not blanked out, enter 'admin'. Then enter the password that was set during the local configuration stage. Once logged in, the iPEPS will show the video output from the host system (if one is connected), or otherwise a 'No Signal' message.
3 Click the Configure button in the top right hand corner of the window to display the configuration menu ↓

Several of the options within the configuration menu duplicate those that are available in the local configuration (Dual Access model only). However, there are other settings that are only available here.

For more information about each menu option, please see Appendix 5 - Remote configuration menus in the 'Further information' chapter.

Networking issues

Thanks to its robust security the iPEPS offers you great flexibility in how it integrates into an existing network structure. The iPEPS is designed to reside either on an internal network, behind a firewall/router or alternatively with its own direct Internet connection.

Positioning iPEPS in the network

Every network setup is different and great care needs to be taken when introducing a powerful device such as the iPEPS into an existing configuration. A common cause of potential problems can be in clashes with firewall configurations. For this reason the iPEPS is designed to be intelligent, flexible and secure. With the minimum of effort the iPEPS can reside either behind the firewall or alongside with its own separate Internet connection.

    E --> F["Firewall/ router"]
    F --> G["Local network connection"]
    G --> H["iPEPS"]

IMPORTANT: When the iPEPS is accessible from the public Internet or dial up connection, you must ensure that sufficient security measures are employed.

Placing iPEPS behind a router or firewall

A possible point of contention between the iPEPS and a firewall can occasionally arise over the use of IP ports. Every port through the firewall represents a potential point of attack from outside and so it is advisable to minimise the number of open ports. The iPEPS usually uses two separate port numbers, however, these are easily changeable and can even be combined into a single port.

IMPORTANT: The correct configuration of routers and firewalls requires advanced networking skills and intimate knowledge of the particular network. Adder Technology cannot provide specific advice on how to configure your network devices and strongly recommend that such tasks are carried out by a qualified professional.

Port settings

As standard, the iPEPS uses two ports to support its two types of viewer:

• Port 80 for users making contact with a web browser, and
• Port 5900 for those using the VNC viewer.

When these port numbers are used, VNC viewers and web browsers will locate the iPEPS correctly using only its network address. The firewall/router must be informed to transfer traffic, requesting these port numbers, through to the iPEPS.

When a web server is also on the local network

Port 80 is the standard port used by web (HTTP) servers. If the iPEPS is situated within a local network that also includes a web server or any other device serving port 80 then, if you want to use the web browser interface from outside the local network environment, the HTTP port number of the iPEPS must be changed.

When you change the HTTP port to anything other than 80, then each remote browser user will need to specify the port address as well as the IP address. For instance, if you set the HTTP port to '8000' and the IP address is '192.168.47.10' then browser users will need to enter:

http://192.168.47.10:8000

(Note the single colon that separates the IP address and the port number). The firewall/router would also need to be informed to transfer all traffic to the new port number through to the iPEPS.

If you need to change the VNC port number

If you change the VNC port to anything other than 5900, then each VNC viewer user will need to specify the port address as well as the IP address. For instance, if you set the VNC port to '11590' and the IP address is '192.168.47.10' then VNC viewer users will need to enter:

192.168.47.10::11590

(Note the double colons that separate the IP address and port number). The firewall/router would also need to be informed to transfer all traffic to the new port number through to the iPEPS.

Addressing

When the iPEPS is situated within the local network, you will need to give it an appropriate local IP address and IP network mask. This is achieved most easily using the DHCP server option which will apply these details automatically. If a DHCP server is not available on the network, then these details need to be applied manually in accordance with the network administrator.

The firewall/router must then be informed to route incoming requests to port 5900 or port 80 (if available) through to the local address being used by the iPEPS.

    A["Internet"] --> B["Firewall/router address: 129.7.1.10"]
    B --> C["Remote user with VNC viewer accesses IP address: 129.7.1.10 and automatically uses port 5900."]
    B --> D["iPEPS has a local address and net mask, i.e."]
    B --> E["IP address: 192.168.0.3"]
    B --> F["Net mask: 255.255.255.0"]

To discover a DHCP-allocated IP address

Once a DHCP server has allocated an IP address, you will need to know it in order to access the iPEPS via a network connection. To discover the allocated IP address:

1 In either the local or remote Network configuration screens, set the 'Use DHCP' option to 'Yes' and select 'Save'. Once the page is saved, the iPEPS will contact the DHCP server and obtain a new address.
2 Re-enter the same 'Network configuration' screen where the new IP address and network mask should be displayed.

DNS addressing

As with any other network device, you can arrange for your iPEPS to be accessible using a name, rather than an IP address. This can be achieved in two main ways:

• For small networks that do not have a DNS (Domain Name System) server, edit the 'hosts' files on the appropriate remote systems. Using the hosts file, you can manually link the iPEPS address to the required name.
• For larger networks, declare the IP address and required name to the DNS server of your local network.

The actual steps required to achieve either of these options are beyond the scope of this document.

Placing iPEPS alongside the firewall

iPEPS is built from the ground-up to be secure. It employs a sophisticated 128bit public/private key system that has been rigorously analysed and found to be highly secure (a security white paper is available upon request from Adder Technology Ltd). Therefore, you can position the iPEPS alongside the firewall and control a computer that is also IP connected within the local network.

IMPORTANT: If you make the iPEPS accessible from the public Internet, care should be taken to ensure that the maximum security available is activated. You are strongly advised to enable encryption and use a strong password. Security may be further improved by restricting client IP addresses, using a non-standard port number for access.

Ensuring sufficient security

The security capabilities offered by the iPEPS are only truly effective when they are correctly used. A weak password or unencrypted link can cause security loopholes and opportunities for potential intruders. For network links in general and direct Internet connections in particular, you should carefully consider and implement the following:

• Ensure that encryption is enabled.
  By local configuration or by remote configuration.
• Ensure that you have selected secure passwords with at least 8 characters and a mixture of upper and lower case and numeric characters, plus a special character. By remote configuration.
• Reserve the admin password for administration use only and use a non-admin user profile for day-to-day access.
• Use the latest Secure VNC viewer (this has more in-built security than is available with the Java viewer). To download the viewer.
  • Use non-standard port numbers.
• Restrict the range of IP addresses that are allowed to access the iPEPS to only those that you will need to use. To restrict IP access.
  • Do NOT Force VNC protocol 3.3. Remote configuration.
• Ensure that the computer accessing the iPEPS is clean of viruses and spyware and has up-to-date firewall and anti-virus software loaded that is appropriately configured.
• Avoid accessing the iPEPS from public computers.

Security can be further improved by using the following suggestions:

• Place the iPEPS behind a firewall and use port the numbers to route the VNC network traffic to an internal IP address.
  • Review the activity log from time to time to check for unauthorized use.
• Lock your server consoles after they have been used.

A security white paper that gives further details is available upon request from Adder Technology Limited.

Ports

In this configuration there should be no constraints on the port numbers because the iPEPS will probably be the only device at that IP address. Therefore, maintain the HTTP port as 80 and the VNC port as 5900.

Addressing

When the iPEPS is situated alongside the firewall, it will require a public static IP address (i.e. one provided by your Internet service provider).

Operation

Connecting to the iPEPS

The iPEPS offers you two ways to connect:

• Local connection (Dual Access models only),
  • Remote connection by network link,

...and two types of viewer:

• VNC viewer,
• Standard web browser.

Local connection (dual access models only)

The keyboard, video monitor and mouse connected directly to the iPEPS dual access offer password protected access to the host computer.

To make a local connection:

1 Using the keyboard connected directly to the IPEPS dual access, press any key to exit the screensaver and display the logon prompt.

2 Enter your username and password. Providing you have the correct permissions, the screen will display the currently selected host computer.

To view the local control menu

1 Press and hold the hotkeys (usually card), then press and finally release all three keys.

Note: The and keys when pressed in combination are called 'hotkeys' and they signal to the iPEPS that you wish to control it, rather than the host computer. However, if these particular hotkeys clash with another device or program, then your administrator may change them to a different combination. If the combination fails to work, then please contact the system administrator for details.

The local control menu contains numerous options, the most useful of which are:

• Access mode - Allows you to select a 'Private' mode in order to prevent other logged on users from viewing your actions on the host computer. Use □ and □b change between modes. Note: For the courtesy of other users, this mode should be used sparingly. The admin user has the ability to overrule the private setting.
• Return to host - Quits the control menu and displays the host computer screen.

Local connection (continued)

To avoid the 'hall of mirrors' effect

IMPORTANT: Never configure a system so that your viewer is viewing itself. When controlling a host computer using the locally connected keyboard, video monitor and mouse, it is possible to use the VNC viewer or a browser (if the host computer is networked) to create a remote link back to itself. This will set up a 'hall of mirrors' effect, where the computer is viewing itself into infinity. While technically possible, the iPEPS unit is not designed to withstand this treatment and could sustain damage.

Remote connections

From a remote system, you connect to the iPEPS using either of two types of viewer:

    style F fill:#cfc,stroke:#333

Remote connection by VNC viewer

The VNC viewer is a compact application that runs on your remote system and allows you to view and use the iPEPS and its host computer. VNC viewer is readily available from sources such as:

• from the iPEPS itself
• from the RealVNC website

To connect using the VNC viewer

1 Locate and select the VNC viewer icon ⇒

VNC Viewer

A connection details dialog will be displayed:

2 In the 'Server:' entry, type the address of the iPEPS as follows:

v.w.x.y

where v.w.x.y is the IP network address, for example 192.168.0.3

• If you have been asked to also enter a port number.

3 Click the OK button. Depending on the options selected, you may need to confirm certain items. A connection attempt will be made and if successful, an authentication dialog will be displayed:

4 Enter your username and password. The viewer window should now open and show the current host computer. Note: If the Username entry is blanked out then only admin user account is currently defined and only a password is required.

Remote connection by Web browser

You can use a standard Web browser (supported versions) to gain access to the iPEPS and its host computer. As soon as you make contact with the iPEPS it will begin downloading a small Java application to your browser, which will be used only for the duration of your connection.

To connect using your Web browser

1 Launch your standard Web browser as usual.
2 In the Address section, type the address of the iPEPS as follows:

http://v.w.x.y

where v.w.x.y is the IP network address, for example 192.168.0.3

• If you have been asked to also enter a port number.

3 Press A connection attempt will be made. In the browser window, select the 'Connect using built-in Java VNC viewer' option to download a small application that will temporarily empower your browser (on slow connections the application download can take several tens of seconds to complete). Once complete, a connection details dialog will be displayed:

The previously entered iPEPS address will be shown here If required, select the encryption mode - MORE [+]

Options button

Provides a range of viewer and connection settings - MORE (+)

4 Make any necessary option/encryption changes and click the OK button to proceed. Depending on the options selected, you may need to confirm certain items.
5 A second connection attempt will be made and if successful, an authentication dialog will be displayed:

6 Enter your username and password. The viewer window should now open and show the current host computer. Note: If the Username entry is blanked out then only admin user account is currently defined and only a password is required.

Using the viewer window

The viewer window gives you the ability to view and control the iPEPS and its host computer. Its operation is almost identical regardless of whether you used the VNC viewer or your Web browser to display it.

The menu bar

The viewer window presents a menu bar similar to that shown below. Certain items within the toolbar are displayed depending upon your access permissions and/or the iPEPS configuration.

When using the viewer window

What is the best screen resolution to use?

The best resolution for your computer is one that is larger than the screen of the host computer that you are viewing. This will allow you to see everything without scrolling around, as described next.

How do I navigate around a larger screen?

If the screen that you are viewing has a larger resolution than your viewing window you will need to scroll around to see all items. The viewer window allows you to 'bump scroll' (only in full screen mode). This means that when your mouse cursor bumps against the edge of the screen, the screen image will scroll across automatically.

How do I escape from full screen mode?

Press the F8 button. This button is changeable but is most often set to F8.

Why is the + button flashing red?

This happens when a new host screen is viewed (that has not been viewed before). Click the Button to perform an auto calibration for the screen and the mouse. See Auto calibrate for important information about this feature.

How do I remove traces of moved items from the screen?

When you move an item or window across the screen, sometimes it can leave unsightly trails. These are called artifacts and can be particularly prevalent when the connection speed is low. To remove artifacts, click the 'Controls' button and select the 'Refresh screen' option. See Controls.

How do I make the most of a slow connection?

The VNC viewer is slightly better suited to slower connections than the browser viewer because it offers more options. Click the Options button of the VNC viewer when entering the iPEPS address during log on.

Adjust the Threshold setting

Ensure that the video Threshold setting is set higher than the automatic setting suggests. Tweak this setting manually to ensure the best setting.

Fewer colours

Select the Low (64 colours) mode. The Very low option offers hardly any improvement and looks a lot worse.

Rate limit mouse events

When selected, this mode greatly reduces the mouse movement data that are sent to the host computer. When you move the local mouse, the remote cursor will catch up roughly once per second.

Mouse pointers

Both viewers provide a double mouse cursor to help overcome any delays caused by slow connections. When you move your mouse you will see two mouse cursors, a local one that responds immediately to your movements and a second, slower moving, cursor that represents the current mouse position at the host.

Re-synchronise mouse

If you find that your local mouse pointer and that of the host are not correctly synchronised, use this feature to re-align their movements. This operation is also selectable from the Controls menu.

To re-synchronise the mouse

1 Click the button and then click OK in the subsequent pop-up message. Note: If you find that this doesn't work, you may need to perform a mouse calibration again.

Access mode - shared/private

Up to five users can be simultaneously logged-on (four remote users plus one local user) and during normal operation, all are able to see the same view of the currently selected host. If you need to perform a sensitive task that should not be viewed by other users, you can change the access mode to Private. This action blanks the viewer window for all other logged on users.

Note: For the courtesy of other users, this mode should be used sparingly. The admin user has the ability to overrule the private setting.

To change the access mode

1 Click one of the arrow buttons adjacent to the Shared/Private indicator.

Auto calibrate

When you visit the host computer for the very first time, your viewer needs to determine the optimum video and mouse settings. The button will remind you to click it by flashing red when a new computer screen is encountered. Performing this step is important because it can help to decrease unnecessary video information being sent across the link, thus improving overall performance.

Once this has been done, the video settings for the host computer will be retained and re-used.

Note: When performing an auto calibration, ensure that the screen image is static (no moving images) and also try to remove any on-screen displays (such as host names or menus). This is because they can affect the calibration process and result in a lower overall performance level. For mouse calibration, ensure that there are no application windows located around the upper left corner of the screen. This is because as the mouse calibration takes place, the cursor may change (to match the application as it skims across the window) and this may confuse the calculation. Also ensure that the host system does not have the mouse cursor trails option enabled.

To auto calibrate the screen and/or mouse

1 Click the button to display the Calibrate options dialog:

2 Click the required action.

A progress indicator will be displayed while the necessary calculations are made.

Upon completion an information dialog will explain the results:

Controls

When clicked, this button reveals a menu of options concerned with keyboard, video and mouse operation.

Single Mouse Mode

This mode is for fast network connections where the cursor response is sufficient to provide instant visual feedback on the remote screen. When enabled, the cursor is 'captured' within the viewer window until you use the 'escape' hot keys.

To escape from single mouse mode, press F8 and then P. Alternatively, enable and use the mouse button escape sequences - see Advanced unit configuration for details.

The single mouse mode does not require calibration.

Resync Mouse

This option has the same effect as the button on the menu bar and re-synchronises the local and remote mouse pointers.

Refresh Screen

This option refreshes the whole screen image to remove any artifacts from moved screen items. This is useful when using very low refresh rates on slow speed communication links.

Mouse Control

This option displays a mouse control dialog and is useful when the remote cursor is failing to respond correctly to your mouse movements, even after using the Resync mouse option.

The mouse control dialog allows you to control the remote mouse cursor using a selection of buttons that you click with your local mouse.

Click to display the Restore mouse dialog where you can reinstate a mouse that has failed to operate correctly. For advice on which mouse type to choose.
For the latter, the connected host computer must support absolute positioning devices.

Keyboard Control

This option displays a keyboard control dialog and is useful for sending keyboard combinations (to the host) that are needed regularly or that are trapped by the iPEPS.

When entering codes:

• means press down the key that follows
  – means release the key that follows
• means press down and release the key that follows
  * means wait 250ms (note: if a number immediately follows the asterisk, then the delay will equal the number, in milliseconds)

It is automatically assumed that all keys specified will be released at the end, so there is need to specify -Ctrl or -Alt if these keys are to be released together.

See Appendix 8 for a list of key sequence codes that can be used.

Examples:

'Ctrl + Alt 12' would be expressed as: +Ctrl+ Alt+1-1+2
+N means press the 'N' key
+Scroll means press the Scroll lock key
+Space means press the space key

Video Settings

This dialog provides access to all of the key video settings that determine image quality and link performance.

Phase

The phase setting adjusts the alignment of the host video output and the remote system video display to achieve the sharpest image.

Horizontal position

Determines the horizontal position of the host screen image within the viewer window.

Vertical position

Determines the vertical position of the host screen image within the viewer window.

Colour, brightness &

contrast

Provides manual sliders and also an automatic setting button to optimise these important video constituents for the current host and connection speed.

Calibrate all

Click to determine the optimum settings for all aspects of video the video connection from the host system.

Display activity

Indicates the level of video activity currently in progress.

Using automatic configurations

• Every setting can be individually subjected to an automatic configuration (click the appropriate 'Auto' button) and most can also be manually adjusted.
• Use the 'Calibrate All' button to automatically determine the optimum settings for all items.

Note: Before using the 'Calibrate All' option, if possible, remove on-screen display (OSD) elements. These OSD elements use different video rates to those of the host system and can affect the setting of the automatic threshold value. iPEPS uses an improved calculation procedure to filter out the effect of these elements. However, best results are obtained when the screen contains only host system information.

Note: To maximise performance, the threshold level is automatically increased by 50% when a slow link is detected.

Setting the Threshold manually

Occasionally it can be useful to manually adjust the Threshold setting, in order to achieve a setting that best suits your particular requirements.

1 Use the 'Calibrate All' function to ensure that all other settings are optimised.
2 Click the Threshold left arrow button to decrement the setting by one and observe the 'Display Activity' indicator.
3 Repeat step 2 until the Display Activity indicator suddenly rises to a much higher level (i.e. 50%). This will mean that you have reached the noise boundary. At this point, increment the Threshold value by 2 or 3 points to achieve an optimum setting.

Advanced Settings

This option contains video signal settings that do not normally need to be adjusted.

Pixel Format

Determines the colour depth and data required to represent each video pixel.

Motion Detection

This option is not available for use with the iPEPS.

Overlap Capture

When enabled, the iPEPS will begin capturing the next frame of video output from the host computer before it has fully completed processing the current frame. In most cases this produces better video performance, however, when moving large objects around the screen (such as an application window), the video image seen at the remote system may exhibit temporary artifacts as the large image moves.

Tile Width and Height

Determines the size of the sample areas into which the source video screen is divided for examination purposes. Smaller sizes result in more areas to sample, larger areas result in more frequent screen area refreshes. 16 is considered to be the optimum size for both the width and height settings.

Virtual Media

Please see the next page for details.

Info

When selected, this option displays an information dialog showing the current logged on users, the current host, its video mode and its mouse motion details.

Virtual Media

The Adder Virtual Media feature allows you to remotely make files available to the host computer linked to the iPEPS. Single files or collections of files and folders up to 2GB in size can be quickly transferred via the VNC link. This can prove to be an invaluable tool when upgrading the host computer from remote positions.

In order to use the Adder Virtual Media feature, the VM link must be made between the iPEPS and a USB port on the host computer. See Host computer connections for details.

To remotely transfer files to a host computer

1 On the remote system, log into the iPEPS using the VNC viewer in the usual manner.
2 On the remote system, select the file(s), folder(s) or storage device (i.e. hard drive, CD-ROM, memory stick) that you wish to transfer to the host computer (to a maximum of 2GB) in either of the following ways:

- Within the VNC viewer window, press F8 and then V. A quick scan will be made of the available storage devices and a popup similar to the following will be displayed:

Select the required storage device or file/folder, choose an appropriate 'Drive Type' (virtual CD, floppy or disk (directory)) and click OK. The selected device will be tagged for transfer but no other action will take place at this point.

- Using Windows Explorer (or the Apple Finder), locate and copy the required file, folder or drive to the clipboard.

On the remote system, within the VNC viewer window, click the Controls button and then select the Virtual Media option. A popup similar to the following will be displayed:

Click the 'Create VM Drive' button to announce file availability to the host computer, whereupon a popup will confirm that the new virtual media disk is built.

Note that using either of the two methods outlined above, no files or folders are transferred at this point, instead the iPEPS will simulate a removable storage device at host computer. This will appear within Windows Explorer or Apple Finder exactly as a floppy disk, removable drive or memory stick would.

3 On the host computer (either directly from iPEPS local console or via the VNC viewer) locate the new virtual drive and access the files as necessary. Files will be transferred to the host computer as they are specifically requested by the actions of the host computer.

Downloading VNC viewer from the iPEPS

The iPEPS has the ability to distribute its own VNC viewer application.

To download the VNC viewer

1 Open your Web browser.
2 Enter the network address where the iPEPS is situated (in the form: http://192.168.0.3) and make the link.
3 In the opening iPEPS screen, click the link that offers to download the secure VNC viewer 'from the unit'.
4 Save the download file (vncviewer.exe) to your system.
5 Select and run the downloaded file and then connect to the iPEPS using the VNC viewer application.

If you need to enter a port number

Usually, when you make a network connection to the iPEPS (either using the VNC viewer or a Web browser) you simply enter the IP address, i.e. 192.168.0.3. However, if a special configuration is necessary, then you may be asked to specify a port number as well as the IP address.

What is a port?

To enter a port number in a Web browser

1 Enter the required IP address in the usual Address box, i.e. http://192.168.0.3
2 At the end of the IP address, add a single colon and then enter the port number (in this example, the required port number is 8000), i.e. http://192.168.0.3:8000
3 Continue with the standard Web browser instructions.

To enter a port number in VNC viewer

1 Enter the required IP address in the usual 'Server' box, i.e. http://192.168.0.3
2 At the end of the IP address, add two colons and then enter the port number (in this example, the required port number is 11590), i.e. http://192.168.0.3::11590
3 Continue with the standard VNC viewer instructions.

Viewer encryption settings

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four encryption options. The resulting actions of certain options depend upon how the iPEPS to which you are connecting is configured:

• Always on - This setting will ensure that the link is encrypted, regardless of the iPEPS encryption setting.
• Let server choose - This setting will follow the configuration of the iPEPS. If the iPEPS has a preference to encrypt the link, then it will be so, otherwise the link will not be encrypted.
• Prefer off - This setting will configure an un-encrypted link if the iPEPS will allow it, otherwise it will be encrypted.
• Prefer on - If the iPEPS allows it, this setting will configure an encrypted link, otherwise it will be un-encrypted.

Whenever encryption does take place, the viewer will first need to create the necessary secure key before the connection process can continue.

Supported web browsers

The following web browsers have been tested and found to work correctly with iPEPS.

Windows

- Internet Explorer 5.50 and above, with Microsoft [Java] Virtual Machine (release 5.50), with Java Runtime Environment 1.3 or above.

Linux

• Netscape 4.61 and above, with Java Runtime Environment 1.1 or above.
• Opera, with Java Runtime Environment 1.1 or above.

Remote network users are unable to contact the iPEPS

• Check that the correct address is being used by the remote users.
• Check the network settings. Check that the users network address has not been excluded in the IP access control section.
• If the iPEPS is situated behind a firewall, check that the relevant ports are being allowed through the firewall and are being correctly routed.
• Check the end panel indicators, the LNK indicator should be on. If the network link is a 100Mbps connection, the 100 indicator should also be on.

The remote cursor is not correctly responding to my mouse movements

- Recalibrate the mouse. When doing so, ensure that the host system does not have mouse cursor trails enabled and that the top left corner of the screen is clear of application windows.

When logging on using VNC viewer, I cannot enter a username

- Either, the VNC viewer is an old version (download a new one) or only the admin user has been configured on the iPEPS.

Appendix 1 - Local configuration menus

This section covers the control menus that are available when you are using the locally connected keyboard, video monitor and mouse.

To access the local configuration menus

On the locally connected keyboard, simultaneously press Ctrl Alt C.

Note: If the standard hotkeys (CTRL + ALT) have been changed, then you need to use those keys together with C to access the menus.

Select the 'Configuration' option to display:

graph TD
    A["Configuration"] --> B["iPEPS"]
    B --> C["UnitConfiguration"]
    B --> D["NetworkConfiguration"]
    B --> E["ResetConfiguration"]
    C --> F["Select the required option: Unit configuration, Network configuration, Reset configuration"]
    D --> F
    E --> F
    F --> G["Back"]

Unit configuration

This page provides access to a selection of both basic and fundamental settings for the iPEPS.

Keybd layout

Use the arrow buttons to match the keyboard layout expected by the host system.

Admin password

Enter the password that will be used to gain administrator access to the iPEPS. There can only be one admin user and only that user is given access to the configuration menus. The admin password background will be red until a reasonably secure password has been entered.

Unit name

The name entered here will be displayed on the local menus and the remote VNC/browser windows.

Hot keys

Use the left and right arrow keys to select an appropriate hot key sequence for the locally connected keyboard. This sequence is used in combination with other keypresses to access the on-screen menus. The options are: Ctrl+Alt (default), Ctrl+Shift, Alt+Shift, Alt Gr, Left + Right Alt, Left Ctrl + Alt or Right Ctrl + Alt.

To get here

1 Use the local keyboard and log on as the 'admin' user.
2 Press Off Alt G (hotkeys may be different).
3 Select 'Configuration'.
4 Select 'Unit configuration'.

Screensaver

Use the left and right arrow keys to select an appropriate period of inactivity on the local keyboard or mouse before a screensaver is displayed and the user is logged out. This setting applies to local users only and once the screensaver is displayed, for security purposes the user is required to log in again. The timeout period can be selected between 5 minutes and 1 day (24 hours) or you can choose the OFF setting to disable the screensaver feature. Note: The Idle timeout option serves a similar purpose for remote connections.

Time and date

Use the left and right arrow keys to select the correct time and date. The time entry uses the 24 hour clock notation. The internal real time clock will continue to run for roughly one week without power to the iPEPS, after that it will be lost and require resetting. Use the up and down arrow keys to move between each of the sections within the time and date entries.

Encryption

Three options are available: Always on, prefer off, prefer on. The one to choose depends on the specific details of your installation - see Encryption settings for details. The use of encryption imposes a slight performance overhead of roughly 10% but is highly secure against third party intrusion.

Network configuration

This page allows you to configure the various aspects of the IP port and its relationship with the local network.

MAC address

Media Access Control address – this is the unique and unchangeable code that was hard coded within your iPEPS unit when it was built. It consists of six 2-digit hexadecimal (base 16) numbers separated by colons. A section of the MAC address identifies Adder Technology as the manufacturer, while the remainder is effectively the unique electronic serial number of your particular unit.

Use DHCP

DHCP is an acronym for 'Dynamic Host Configuration Protocol'. Its function is particularly useful when connecting to medium size or larger networks. When this option is selected, your iPEPS will attempt to locate a DHCP server on the network. If such a server is located, it will supply three things to the iPEPS: an IP address, an IP network mask (also known as a Subnet mask) and a Gateway address. These are not usually granted permanently, but on a 'lease' basis for a fixed amount of time or for as long as the iPEPS remains connected and switched on. Discover allocations.

IP address

This is the identity of the iPEPS within a network. The IP address can be thought of as the telephone number of the iPEPS. Unlike the MAC address, the IP address can be altered to suit the network to which it is connected. It can either be entered manually or configured automatically using the DHCP option. When the DHCP option is enabled, this entry is greyed out.

Net mask

Also often called the 'subnet-mask', this value is used alongside the IP address to help define a smaller collection (or subnet) of devices on a network. In this way a distinction is made between locally connected devices and ones that are reachable elsewhere, such as on the wider Internet. This process helps to reduce overall traffic on the network and hence speed up connections in general.

To get here

1 Use the local keyboard and log on as the 'admin' user.
2 Press Ctrl Alt G (hotkeys may be different).
3 Select 'Configuration'.
4 Select 'Network configuration'.

Gateway

This is the address of the device that links the local network (to which the iPEPS is connected) to another network such as the Internet. Usually this is a network switch or router and it will be used whenever a device to be contacted lies outside the local network.

VNC port

This is the logical link through which communications with a remote VNC viewer will be channelled (see What is a port?). The default setting is 5900 which is a widely recognised port number for use by VNC software. However, in certain circumstances it may be advantageous to alter this number - see Security issues with ports for more details.

Note: The VNC port and HTTP port can be set to the same port number in order to simplify router and firewall configuration. If this is done then the iPEPS will "listen" for both types of traffic on the single port.

HTTP port

This is the logical link through which communications with a remote web browser will be channelled. The default setting of 80 is an established standard for web (HTTP - HyperText Transfer Protocol) traffic though this can be changed to suit your local network requirements.

Clear IP access control

This option removes all entries from the IP access control feature within the iPEPS. The IP access control feature (configurable by a remote admin user) allows certain network address ranges to be denied access to the iPEPS. If set incorrectly, it is possible to exclude all network users and so this option provides an emergency recovery point.

Reset configuration

This option allows you to completely reset the iPEPS.

WARNING: This process will remove all settings and return the unit to use its original state. A complete reconfiguration will be required before it can be used.

To reset the iPEPS configuration

1 With the RESET option highlighted, press

2 The first screen of the initial configuration process will be displayed. See Initial configuration for details.

To get here

1 Use the local keyboard and log on as the 'admin' user.
2 Press Ctrl Alt C (hotkeys may be different).
3 Select 'Configuration'.
4 Select 'Reset configuration'.

Appendix 2 - VNC viewer connection options

When you are connecting to the iPEPS using the VNC viewer, a number of options are available.

Click here to access the options

There are six tabbed pages of options:

Colour/Encoding

Auto select

When ticked, this option will examine the speed of your connection to the iPEPS and apply the most suitable encoding method. This option is suggested for the majority of installations.

Preferred encoding

There are three manually selectable encoding methods which are accessible when the Auto select option is unticked.

• ZRLE – This is a highly compressed method that is best suited to slow modem connections.
• Hextile – This method offers better performance than the ZRLE when used over a high speed network because there is no need for the iPEPS to spend time highly compressing the data.
• Raw – This is a primitive, uncompressed method that is mainly used for technical support issues. You are recommended not to use this method.

IMPORTANT: If you make any changes to the options given here and wish to retain them for successive connection sessions, you must save the changes. To do this, change to the 'Load / Save' tab and click the 'Save' button.

Colour level

This section allows you to select the most appropriate colour level for the speed of the connection to the iPEPS. Where the connection speed is slow or inconsistent there will be a necessary compromise between screen response and colour depth.

• Full – This mode is suitable only for fast network connections and will pass on the maximum colour depth being used by the host system.
• Medium (256 colours) – This mode reduces the host system output to a 256 colour mode and is more suitable for ISDN and fast modem connections.
• Low (64 colours) – This mode is suitable for slower modern connections and reduces the host system output to 64 colours.
• Very low (8 colours) – This mode provides very rudimentary picture quality and hardly any speed advantage over the 64 colour setting. You are recommended not to use this mode.

Inputs

Enable all inputs

When selected, allows keyboard, mouse and clipboard data to be transferred between server and viewer systems.

Disable all inputs (view-only mode)

When selected, prevents control data being passed between server and viewer. Viewer can display the server output, but cannot control it.

Customise

Allows you to select which data can be transferred between server and viewer.

Send pointer events to server

When un-ticked, the VNC viewer

will not send mouse movement or click data to the iPEPS or host system.

Send keyboard events to server

When un-ticked, the VNC viewer will not send keyboard information to the iPEPS or host system.

Send clipboard changes to server

This feature is restricted to software server versions of VNC and has no effect on iPEPS installations.

Accept clipboard changes from server

This feature is restricted to software server versions of VNC and has no effect on iPEPS installations, except for retrieving the activity log as described in the logging and status section.

Rate-limit mouse move events

When ticked, this feature reduces the mouse movement information that is sent to the iPEPS and host system. This is useful for slow connections and you will notice that the remote cursor will catch up with the local cursor roughly once every second.

Enable 3-button mouse emulation

This feature allows you to use a 2-button mouse to emulate the middle button of a 3-button mouse. When enabled, press the left and right mouse buttons simultaneously to create a middle button action. You are advised to generally use a 3-button mouse.

Pass special keys directly to server

When ticked, 'special' keys (the Windows key, the Print Screen key, Alt+Tab, Alt+Escape and Ctrl+Escape) are passed directly to the iPEPS rather than being interpreted locally.

Menu key

This feature allows you to select which function key is used to display the VNC viewer options menu. The menu key is only way to exit from the full screen viewer mode.

IMPORTANT: If you make any changes to the options given here and wish to retain them for successive connection sessions, you must save the changes. To do this, change to the 'Load / Save' tab and click the 'Save' button.

Scaling

No Scaling

No attempt is made to make the screen image fit the viewer window. You may need to scroll horizontally and/or vertically to view all parts of the screen image.

Scale to Window Size

Adjusts the server screen image to suit the size of the viewer window.

Custom Size

Adjusts the server screen image according to the Width and Height settings in the adjacent fields. A drop box to the right of the fields allows you to define the image size by percentage or by pixels, as required.

Preserve Aspect Ratio

When ticked, maintains a consistent ratio between the horizontal and vertical dimensions of the screen image.

Misc

Shared connection (do not disconnect other viewers)

This option does not apply to iPEPS connections.

Full screen mode

When ticked, the VNC viewer will launch in full screen mode. Use the menu key (usually F8) to exit from full screen mode.

Render cursor locally

This option does not currently apply to iPEPS connections.

Allow dynamic desktop resizing

When ticked, the viewer window will be automatically resized whenever the host system's screen resolution is altered.

Only use protocol version 3.3

This option does not apply to iPEPS connections.

Beep when requested to by the server

When ticked, your local system will beep in response to any error beeps emitted by the iPEPS.

Offer to automatically reconnect

When ticked, the viewer will offer to restore a lost connection with the server.

Try Single Sign-On if server allows it

This option does not apply to iPEPS connections.

IMPORTANT: If you make any changes to the options given here and wish to retain them for successive connection sessions, you must save the changes. To do this, change to the 'Load / Save' tab and click the 'Save' button.

Identities

This feature helps your VNC viewer to confirm that a revisited iPEPS is genuine and not another device masquerading as an iPEPS. The list given will retain the identities of all visited units (that have full security enabled).

When you first make a secure connection to the iPEPS, the security information for that iPEPS unit is cached within this Identities tab (i.e. the "identity" is known). The next time that you connect to the iPEPS, its identity is checked against the stored version. If a mismatch is found between the current and the stored identities then a warning will be issued to you.

If an existing iPEPS is fully reconfigured then it will need to issued with a new identity. In this case the previous identity, listed in this tab, should be removed so that a new identity can be created on the next connection.

Load / Save

Configuration File - Reload

Allows you to load a configuration file saved from this, or another viewer.

Configuration File - Save

Allows you to save the current settings so that they can be copied from one viewer to another.

Configuration File - Save As...

Allows you to save the current settings under a new name so that they can be copied from one viewer to another.

Defaults - Reload

When clicked, all connection options are returned to the default settings that are currently saved.

Defaults - Save

When clicked, saves the current connection options as the default set that will be used in all subsequent VNC connections.

Appendix 3 - VNC viewer window options

Click the VNC icon in the top left corner of the viewer window (or press F8) to display the window options:

Appendix 4 - Browser viewer options

When you are connecting to the iPEPS using a Web browser, a number of options are available.

Click here to access the options

There are four options pages:

Encoding and colour level

Auto select

When ticked, this option will examine the speed of your connection to the iPEPS and apply the most suitable encoding method. This option is suggested for the majority of installations.

Preferred encoding

There are three manually selectable encoding methods which are accessible when the Auto select option is unticked.

• ZRLE – This is a highly compressed method that is best suited to slow modem connections.
• Hextile – This method offers better performance than the ZRLE when used over a high speed network because there is no need for the iPEPS to spend time highly compressing the data.
• Raw – This is a primitive, uncompressed method that is mainly used for technical support issues. You are recommended not to use this method.

Colour level

The colour level is fixed at Medium (256 colours) for almost all browsers.

Appendix 5 - Remote configuration menus

This section covers the configuration menus that are available to remote admin users using either the VNC viewer or the browser methods of access.

To access the remote configuration menus

- Click the Configure button in the top right corner of the window when logged on as the admin user.

User accounts

This section allows you to manage up to sixteen separate accounts.

The first of the sixteen accounts is the admin account and is the only account with access rights to the configuration menus. The user name and access rights are fixed for the admin account, the only change possible for this account is the password.

There are fifteen user account positions.

To create a new account

1 Enter the required User Name to activate that position (the Password and access tick box positions will become editable).
2 Optionally enter a password for the user account.
3 Tick/untick the Local and/or Remote options that are appropriate to the user.
4 Click the Save button to register your changes.

To get here

1 Using VNC viewer or a browser, log on as the 'admin' user.
2 Click the 'Configure' button in the top right corner.
3 Click the 'User Accounts' option.

User Name

All user names must consist of lower case characters or numbers only. No symbols or upper case characters are permissible. The user name can be between 1 and 16 characters in length.

Password

Each password must be between 8 and 16 characters and contain at least 1 letter, 1 number and a special character. The password background remains amber whilst the password is considered too weak.

Local

When ticked, the selected user can gain access using the local KVM console directly connected to the iPEPS (dual access models only).

Remote

When ticked, the selected user can gain access via an IP network link, such as a local intranet or the wider Internet (depending on how the iPEPS is connected).

Unit configuration

This page provides access to a selection of both basic and fundamental settings for the iPEPS. Many of the settings displayed here are also accessible through the on-screen menu on the locally attached keyboard, mouse and monitor.

Hardware Version

Indicates the version of the electronic circuitry within the iPEPS unit.

Firmware Version

Indicates the version of the hardwired software within the iPEPS flash memory.

Host Keyboard Layout

Use the arrow buttons to match the keyboard layout expected by the host system.

Admin Password

Enter the password that will be used to gain administrator access to the iPEPS. There can only be one admin user and only that user is given access to the configuration menus.

To get here

1 Using VNC viewer or a browser, log on as the 'admin' user.

2 Click the 'Configure' button in the top right corner.
3 Click the 'Unit Configuration' option.

Unit Name

The name entered here will be displayed on the local menus and the remote VNC viewer/browser windows.

Local Hot Key Sequence

Use the arrow buttons to select an appropriate hot key sequence for the locally connected keyboard. This sequence is used in combination with other keypresses to access the on-screen menus. The options are: Ctrl+Alt (default), Ctrl+Shift, Alt+Shift, Alt Gr, Left + Right Alt, Left Ctrl + Alt or Right Ctrl + Alt.

Screensaver Timeout

Use the arrow keys to select an appropriate period of inactivity before a screensaver is displayed and the user is logged out. This setting applies to local users only and once the screensaver is displayed, for security purposes the user is required to log in again. The timeout period can be selected between 5 minutes and 1 day (24 hours) or you can choose the OFF setting to disable the screensaver feature.

Encryption

Three options are available: Always on, prefer off, prefer on. The one to choose depends on the specific details of your installation - see Encryption settings for details. The use of encryption imposes a slight performance overhead of roughly 10% but is highly secure against third party intrusion.

Advanced unit configuration

Click this button to display advanced options that do not normally require alteration.

Advanced unit configuration

Displays advanced options that do not normally require alteration.

To get here

1 Using VNC viewer or a browser, log on as the 'admin' user.
2 Click the 'Configure' button in the top right corner.
3 Click the 'Unit Configuration' option.
4 Click the 'Advanced Unit Configuration' option.

Force VNC Protocol 3.3

IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacy version that does not offer any encryption.

Idle Timeout

Determines the period of inactivity on a remote connection before the user is logged out. The idle timeout period can be set to any time span, expressed in minutes. Note: The Screensaver option serves a similar purpose for local connections.

Protocol Timeout

Sets the time period by which responses should have been received to outgoing data packets. If the stated period is exceeded, then a connection is considered lost and terminated.

Background Refresh Rate

Use the arrow keys to alter the refresh rate for screen images via remote links. This allows you to tailor the screen refresh to suit the network speed. The options are: Slow, Medium, Fast or Disabled. When the disabled option is selected, the remote users will need to manually refresh the screen.

Note: When a low connection speed is detected, the background refresh is automatically disabled, regardless of the settings of this option.

Mouse Latency Allowance

This option is used during calibration to account for latency delays (caused as signals pass through a device) introduced by some KVM switches from alternative manufacturers.

During calibration, the iPEPS waits for 40ms after each mouse movement before sampling the next. If a KVM device adds a significant delay to the flow of data, the calibration process can be lengthened or may fail entirely. The value entered here is added to (or subtracted from) the default 40ms sampling time.

Note: You can enter negative values (down to -40) in order to speed up the calibration process when using fast KVM switches. Use this option with caution as it can adversely affect the calibration process.

Mouse Rate

Defines the rate at which mouse movement data are transmitted to the system. The default option is 20ms, which equates to 50 mouse events per second. This default rate can prove too fast when passed through certain connected KVM switches from alternative manufacturers. In such cases, data are discarded causing the local and remote mouse pointers to drift apart. If this effect is encountered, increase the mouse rate to around 30ms (data are then sent at a slower rate of 33 times per second).

Single Mouse Mode Mouse Switch

Allows you to select the mouse button combination that can be used to exit from single mouse mode (when active). Options are: Disabled, Middle+Right Button, Middle+Left Button.

Use Quick Mouse Calibration

Invokes optimised calibration techniques that handle the majority of mouse types.

Use Absolute Mouse by default

When selected, absolute mouse positioning data will be used rather than relative values.

Set cursor to arrow

Change remote cursor from a default dot to arrow shape.

Behaviour for admin connections when limit reached

Determines what should occur when four global connections already exist and a fifth, administrator connection attempt is made. Options are: Replace oldest connection, Replace newest connection and Don't replace. Only non-administrator connections can be terminated in this way.

Use VESA GTF

When ticked, the VESA Generalized Timing Formula will be used to help determine the correct input video resolution and timing details. See Appendix 9 for a list of all supported video modes.

Enable Virtual Media

When checked, allows file transfers to occur. See page 32.

Upgrade firmware

Places the unit into upgrade mode.

Reset Unit

Performs a complete cold boot of the iPEPS unit.

Time & date configuration

This page allows you to configure all aspects relating to time and date within the iPEPS.

Time and Date

Use the arrow buttons to set the correct current time.

Use NTP

When this option is selected, the iPEPS will synchronise its internal clocks using information from the (Network Time Protocol) server listed in the NTP Server IP address field.

NTP Server IP address

Optionally enter the IP address for a known Network Time Protocol server.

Set Time from NTP Server

Click to immediately use the time and date information from the listed NTP server.

Timezone specifier

Optionally enter a recognised timezone specifier related to the current position of the iPEPS. When an NTP server is used, the specifier will be used to provide the correct real time.

The timezone specifier takes the following form:

std offset dst [offset], start[/time], end[/time]

The std and offset specify the standard time zone, such as GMT and 0, or CET and -1, or EST and 5, respectively.

The dst string and [offset] specify the name and offset for the corresponding Daylight Saving Time zone; if the offset is omitted, it defaults to one hour ahead of standard time.

The remainder of the specification describes when Daylight Saving Time is in effect. The start field is when Daylight Saving Time goes into effect and the end field is when the change is made back to standard time. The most common format used for the daylight saving time is: mm.w.d

Where: m specifies the month and must be between 1 and 12. The day d must be between 0 (Sunday) and 6. The week w must be between 1 and 5; week 1 is the first week in which day d occurs, and week 5 specifies the last d day in the month.

The time fields specify when, in the local time currently in effect, the change to the other time occurs. If omitted, the default is 02:00:00.

Typical examples are:

UK: GMT0BST,M3.5.0/1,M10.5.0/2

Central Europe: CET-1CEST,M3.5.0/2,M10.5.0/3

US Eastern (2006): EST5EDT,M4.1.0/2,M10.5.0/2

US Pacific (2006): PST8PDT,M4.1.0/2,M10.5.0/2

US Eastern (from 2007): EST5EDT,M3.2.0/2,M11.1.0/2

US Pacific (from 2007): PST5PDT,M3.2.0/2,M11.1.0/2

This is the identity of the iPEPS within a network. The IP address can be thought of as the telephone number of the iPEPS. Unlike the MAC address, the IP address can be altered to suit the network to which it is connected. It can either be entered manually or configured automatically using the DHCP option. When the DHCP option is enabled, this entry is greyed out.

In this way a distinction is made between locally connected devices and ones that are reachable elsewhere, such as on the wider Internet. This process helps to reduce overall traffic on the network and hence speed up connections in general.

IP Gateway

This is the address of the device that links the local network (to which the iPEPS is connected) to another network such as the wider Internet. Usually the actual gateway is a network switch or router and it will be used whenever a required address lies outside the current network.

VNC Port

This is the logical link through which communications with a remote VNC viewer will be channelled (see What is a port?). The default setting is 5900 which is a widely recognised port number for use by VNC software. However, in certain circumstances it may be advantageous to alter this number - see 'Security issues with ports' for more details.

HTTP Port

This is the logical link through which communications with a remote web browser will be channelled (see What is a port?). The default setting of 80 is an established standard for web (HTTP - HyperText Transfer Protocol) traffic though this can be changed to suit your local network requirements.

IP Access Control

This section allows you to optionally specify ranges of addresses which will or won't be granted access to the iPEPS. If this option is left unchanged, then the default entry of '+0.0.0.0/0.0.0.0' ensures that access from all IP addresses will be permitted. See Setting IP access control for details.

Setting IP access control

The golden rule with this feature is 'Include before you exclude' or to put it another way 'Arrange allowed addresses in the list before the denied addresses'.

This is because the positions of entries in the list are vitally important. Once a range of addresses is denied access, it is not possible to make exceptions for particular addresses within that range. For instance, if the range of addresses from A to F are denied access first, then the address C could not be granted access lower down the list. Address C needs to be placed in the list before the denied range.

IMPORTANT: This feature should be configured with extreme caution as it is possible to deny access to everyone. If such an error occurs, see Clear IP access control for details about how to regain access.

In the list, access control addresses prefixed by '+' are allow entries while those prefixed by '-' are deny entries.

To get here

1 Using VNC viewer or a browser, log on as the 'admin' user.
2 Click the 'Configure' button in the top right corner.
3 Click the 'Network Configuration' option.

To define a new IP access control entry

1 Click the Add button to display a popup dialog:

Network/Address

Enter the network address that is to be allowed or denied access. If a range of addresses is being specified then specify any one of the addresses within the range and use the Mask entry to indicate the size of the range.

Mask

Enter an IP network mask that indicates the range of addresses that are to be allowed or denied access. For instance, if only a single specified IP address were to be required, the mask entry would be 255.255.255.255 in order to specify a single location. See Calculating the mask for IP access control for details.

Access

Use the arrow buttons to select either 'Allow' or 'Deny' as appropriate.

2 Enter the base network address, the mask and select the appropriate access setting.
3 Click the OK button.

To reorder access control entries

IMPORTANT: When reordering, ensure that any specific allowed addresses are listed higher in the list than any denied addresses. Take care not to invoke any deny access settings that would exclude valid users.

1 In the access control list, click on the entry to be moved.
2 Click the Up or Down buttons as appropriate.

To edit/remove access control entries

1 In the access control list, click on the appropriate entry.
2 Click either the Edit or Remove button as appropriate.

Hotkey sequences

iPEPS allows you to enter commands that take the form of hotkey sequences that emulate standard keypress combinations.

Hotkey sequences

Almost any combination of keypresses can be emulated using the following notations:

• means press down the key that follows,
• means release the key that follows,
  +- means press and then release the key that follows,
  * means add a delay. The standard delay period is 250ms, however, if a number immediately follows the asterisk, this will define an alternate delay period (in milliseconds).

A list of permissible keypresses and information about how to abbreviate them are given in Appendix 8.

Notes

• The entries are not case sensitive.
- It is not necessary to specify all keys to be released at the end because they are all released automatically after the last code.

Examples

To send the command Ctrl + Alt 4 you should use the following: +Ctrl+Alt+4. To send the command Ctrl + Alt 12 you should use the following: +Ctrl+ALT+1+2 (the '+-1' entry causes the 1 key to be pressed and released before the 2 key is pressed).

To send the command Scroll lock 1 + Enter (with a 500ms delay) you should use the following: +-Scr*500+1+Ent

Logging and status

Appendix 6 – Addresses, masks and ports

IP address, network masks and ports are all closely linked in the quest for one device to find another across disparate network links.

IP addresses

As a rough analogy, consider how you use the telephone system. The phone number for Adder Technology in the UK is 0044 (0)1954 780044. This number consists of three distinct parts:

• 0044 connects from another country to the UK
• (0)1954 selects the main telephone exchange in the Bar Hill area of Cambridgeshire, and
• 780044 is the unique code for Adder Technology within Bar Hill.

The important parts of the whole number depend on where you are. If you were based in the same local area as Adder Technology, there would be no point in dialling out of the UK, or even out of the area. The only part of the whole number that you are interested in is the final part: 780044.

In a similar way to the various parts of the telephone number, the four sections (or Octets) of every IP address have different meanings or "weights". Consider the following typical IP address:

192.168.142.154

192 is the most global part of the number (akin to the 0044 of the phone number) and 154 is the most local (similar to the 780044 unique local code of the phone number).

When two network devices communicate with each other, they always "dial the whole number" regardless of their respective locations in a network. However, they still need to know whether the other device is local to them or not, and this is where the net mask comes into play.

Net masks

The net mask (or sub-net mask) informs a device as to its own position within a network. From this it can determine whether any other device is within the same local network or is situated further afield.

Taking the telephone number analogy given in the IP address section, in order to use the telephone system efficiently, it is vital for you to know your location relative to the person you are calling. In this way you avoid dialling unnecessary numbers.

When one network device needs to talk to another, the first thing that it will do is a quick calculation using its own IP address, the other device's IP address and its own net mask. Suppose a device with address 192.168.142.154 and net mask 255.255.255.0 needed to communicate with a device at address 192.168.142.22. The sending device would perform several calculations:

graph TD
    A["192.168.142.154"] --> B["255.255 255.0"]
    B --> C["192.168.142.000"]
    C --> D["Result"]
    E["192.168.142.22"] --> F["255.255 255.0"]
    F --> G["192.168.142.000"]
    G --> H["Address is local"]
    I["Destination device IP address"] --> J["255.255 255.0"]
    J --> K["192.168.142.000"]
    L["Answer: YES"] --> M["4"]

1 The net mask is used to determine the local and global parts of the sender's IP address. Where there is 255 in the mask, the corresponding address slips through, where there is a 0, it is blocked.
2 Where the net mask was 0, the corresponding part of the result is also zero - this section is now known to be the local part of the IP address.
3 The same process is carried out for the destination address, again using the sender's net mask. Now the local parts of both addresses have been equalised to zero, because their values are not important in determining whether they are both in the same local network.
4 The results of the two net mask operations are now compared, if they match, the destination is local. If not, then the sender will still use the same full destination IP address but will also flag the message to go via the local network gateway and out into the wider world.

The reason for doing this? It makes the network, as a whole, much more efficient. If every message for every recipient was shoved straight out onto the Internet, the whole thing would grind to a halt within seconds. Net masks keep local traffic just that - local.

Net masks - the binary explanation

To really understand the operation of a net mask it is necessary to delve deeper into the life blood of computers – binary; this is native digital, where everything is either a 1 (one) or 0 (zero), on or off, yes or no.

The net mask operation described on the previous page is known as a 'bit-wise AND function'. The example of 255.255.255.0 is handy because the last octet is completely zero and is "clean" for illustrative purposes. However, actual net mask calculations are carried out, not on whole decimal numbers, but bit by bit on binary numbers, hence the term 'bit-wise'. In a real local network, a net mask might be 255.255.255.240. Such an example would no longer be quite so clear, until you look at the net mask in its binary form:

11111111.11111111.11111111.11110000

In this case, the four zeroes at the end of the net mask indicate that the local part of the address is formed by only the last four bits. If you use the diagram from the previous example and insert the new net mask, it will have the following effect on the final result:

Thus, when 154 is bit-wise ANDed with 240, the result is 144. Likewise, any local address from 192.168.142.144 through to 192.168.142.159 would produce exactly the same result when combined with this net mask, hence they would all be local addresses. However, any difference in the upper three octets or the upper four bits of the last octet would slip through the mask and the address would be flagged as not being local.

Calculating the mask for IP access control

The IP access control function uses a standard IP address and a net mask notation to specify both single locations and ranges of addresses. In order to use this function correctly, you need to calculate the mask so that it accurately encompasses the required address(es).

Single locations

Some of the simplest addresses to allow or deny are single locations. In this case you enter the required IP address into the 'Network/Address' field and simply enter the 'Mask' as 255.255.255.255 (255 used throughout the mask means that every bit of the address will be compared and so there can only be one unique address to match the one stated in the 'Network/Address' field).

All locations

The other easy setting to make is ALL addresses, using the mask 0.0.0.0 As standard, the IP access control section includes the entry: +0.0.0.0/0.0.0.0 The purpose of this entry is to include all IP addresses. It is possible to similarly exclude all addresses, however, take great care not to do this as you instantly render all network access void. There is a recovery procedure should this occur.

Address ranges

Although you can define ranges of addresses, due to the way that the mask operates, there are certain restrictions on the particular ranges that can be set. For any given address you can encompass neighbouring addresses in blocks of either 2, 4, 8, 16, 32, 64, 128, etc. and these must fall on particular boundaries. For instance, if you wanted to define the local address range:

192.168.142.67 to 192.168.142.93

The closest single block to cover the range would be the 32 addresses from: 192.168.142.64 to 192.168.142.95.

The mask needed to accomplish this would be: 255.255.255.224

When you look at the mask in binary, the picture becomes a little clearer. The above mask has the form: 11111111.11111111.11111111.1100000 Ignoring the initial three octets, the final six zeroes of the mask would ensure that the 32 addresses from .64 (01000000) to .95 (01011111) would all be treated in the same manner. See Net masks - the binary explanation for details.

When defining a mask, the important rule to remember is:

There must be no 'ones' to the right of a 'zero'.

For instance, (ignoring the first three octets) you could not use a mask that had 11100110 because this would affect intermittent addresses within a range in an impractical manner. The same rule applies across the octets. For example, if you have zeroes in the third octet, then all of the fourth octet must be zeroes.

The permissible mask values (for all octets) are as follows:

Mask octet Binary Number of addresses encompassed

255	11111111	1 address
254	11111110	2 addresses
252	11111100	4 addresses
248	11111000	8 addresses
240	11110000	16 addresses
224	11100000	32 addresses
192	11000000	64 addresses
128	10000000	128 addresses
0	00000000	256 addresses

If the access control range that you need to define is not possible using one address and one mask, then you could break it down into two or more entries. Each of these entries could then use smaller ranges (of differing sizes) that, when combined with the other entries, cover the range that you require. For instance, to accurately encompass the range in the earlier example: 192.168.142.67 to 192.168.142.93

You would need to define the following six address and mask combinations in the IP access control section:

Network/address entry Mask entry

192.168.142.67	255.255.255.255	defines 1 address (.67)
192.168.142.68	255.255.255.252	defines 4 addresses (.68 to .7
192.168.142.72	255.255.255.248	defines 8 addresses (.72 to .7
192.168.142.80	255.255.255.248	defines 8 addresses (.80 to .8
192.168.142.88	255.255.255.252	defines 4 addresses (.88 to .9
192.168.142.93	255.255.255.255	defines 1 address (.93)

Ports

If you accept the analogy of IP addresses being rather like telephone numbers, then think of ports as extension numbers. In a company of any size, you generally wouldn't expect the accounts department to share the same telephone with the technical department. Although their calls may all be related to the same company, they concern very different aspects of that company.

It is the same with IP network connections. Although you have only one network link into your computer and only one IP address (phone number), you are probably performing many different tasks through that one link, often at the same time. Thus, when you browse the web your outgoing requests and the incoming information are all channelled through port 80. When you send an email, it travels through port 25 and when you transfer files you are, without knowing it, using port 20.

At the "border crossing" between the wider Internet and every local network attached to it, there is a router that is usually combined with a firewall. One of its main tasks is to direct incoming traffic to the correct place within its local network. A key piece of information to help it do this is the port number:

graph TD
    A["User accesses the company website at: 129.7.1.10 (this automatically uses port 80)."] --> B["Internet"]
    C["User with VNC viewer accesses IP address: 129.7.1.10 (this automatically uses port 5900)."] --> B
    D["Router/firewall address: 129.7.1.10\nRouter is programmed to send port 5900 VNC traffic to local address 192.168.0.3 and port 80 web traffic to local address 192.168.0.42"] --> E["Web server"]
    F["ADDR/FANK /PHP ADDER"] --> E

IPEPS has the local IP address: 192.168.0.3
Web server has the local IP address: 192.168.0.42

Security issues with ports

The settings of port numbers become important when the iPEPS is situated behind a network firewall. In order for a remote VNC viewer or web browser to make contact with your iPEPS, it is necessary for the firewall to allow communication through a particular numbered port to occur.

One specific function of firewalls is to restrict access to ports in order to prevent malicious attackers using them as a route into your network. Every new port that is opened offers a new possibility for hackers and so the number of accessible ports is purposefully kept to a minimum. In such cases, it may be advantageous to change one or both iPEPS ports to use the same number. The other alternative is to place the iPEPS unit outside the firewall and take full advantage of its secure operation features – see Networking issues for details. IMPORTANT: The correct configuration of routers and firewalls requires advanced networking skills and intimate knowledge of the particular network. Adder Technology cannot provide specific advice on how to configure your network devices and strongly recommend that such tasks are carried out by a qualified professional.

ASCII characters

All characters can be entered using their ASCII codes, from 32 to 126 (i.e. A,B,C,

... 1,2,3 etc.) with the exception of the special characters '+', '-', '+-' and '*'

which have special meanings, as explained below.

Codes with special meanings

+ means press down the key that follows,

– means release the key that follows,

+ means press down and release the key that follows,

* means wait 250ms (note: if a number immediately follows the asterisk, then the delay will equal the number, in milliseconds).

Note: Hotkey sequences are not case sensitive.

Creating macro sequences

Hot key macro sequences can be up to 256 characters long. All keys are assumed to be released at the end of a line, however, you can also determine that a key is pressed and released within a sequence. Any of the following three examples will send a command that emulates and a press and release of the Scroll Lock key:

+SCROLL-SCROLL

+-SCROLL

+SCROLL-

Example:

+-SCROLL+-SCROLL+1+ENTER

Press and release scroll twice, press 1 then enter then release all keys (equivalent definition is +SCROLL-SCROLL+SCROLL-SCROLL+1+ENTER-1-ENTER)

Using abbreviations

To reduce the length of the key definitions, any unique abbreviation for a key can be used. For example: "scroll", "scr" and even "sc" all provide an identifiable match for "ScrollLock" whereas "en" could not be used because it might mean "Enter" or "End" ("ent" would be suitable for "Enter").

Note: Hotkey sequences and abbreviations are not case sensitive.

For information about where to enter these codes, please see the sections Host configuration or Keyboard control.

Appendix 9 – Supported video modes

The following video modes are supported and can be automatically configured by the iPEPS. If a recognised video mode cannot be found, the iPEPS will gradually change some of the key parameters to discover whether a video lock can be achieved. Support for VESA GTF (Generalized Timing Formula) is available and can be enabled via the Advanced Unit Configuration screen.

The half width video modes capture every other pixel. These are not generally recommended for normal use but may be used for emergency access to high resolution, high frequency system screens. Half width screens can be expanded to normal width using the scaling features of the viewer.
