ATTENTION

• The AWK-1121/1127 is NOT a portable mobile device and should be located at least 20 cm away from the human body.
• The AWK-1121/1127 is NOT designed for the general public. A well-trained technician should be enlisted to ensure safe deployment of AWK-1121/1127 units, and to establish a wireless network.

Functional Design

LED Indicators

The LEDs on the front panel of the AWK-1121/1127 provide a quick and easy means of determining the current operational status and wireless settings.

The FAULT LED indicates system failures and user-configured events. If the AWK-1121/1127 cannot retrieve the IP address from a DHCP server or if there is an IP conflict, the FAULT LED will blink at one second intervals. The SIGNAL LEDs indicate signal strength.

ATTENTION

The FAULT, SIGNAL, STATE and WLAN LEDs lighting up simultaneously and blinking at one second intervals indicates that the system has failed to boot. This may be due to improper operation or an uncontrollable factor, such as an unexpected shutdown during firmware update. Instructions on how to recover the firmware can be found in Appendix B in the "Firmware Recovery" section.

Beeper

The beeper emits two short beeps when the system is ready.

Reset Button

The RESET button is located on the back panel of the AWK-1121/1127. You can reboot the AWK-1121/1127 or reset it to factory default settings by pressing the RESET button with a pointed object such as an unfolded paper clip.

• System reboot: Hold the RESET button down for under 5 seconds and then release.
• Reset to factory defaults: Hold the RESET button down for more than 5 seconds until the STATE LED starts blinking green. Release the button to reset the AWK-1121/1127.

This chapter explains how to install Moxa's AirWorks AWK-1121/1127 for the first time, and quickly set up your wireless network and test whether the connection is running well. The function guide provides a convenient means of determining which functions you need to use.

The following topics are covered in this chapter:

☐ First-time Installation and Configuration
□ Function Map

First-time Installation and Configuration

Before installing the AWK-1121/1127, make sure that all items in the Package Checklist are in the box. You will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-1121/1127 has a default IP address that must be used when connecting to the device for the first time.

• Step 1: Select the power source.
  The AWK-1121/1127 may be powered by a DC power input or PoE (Power over Ethernet, PoE model only).
• Step 2: Connect the AWK-1121/1127 to a notebook or PC.

Since the AWK-1121/1127 supports MDI/MDI-X auto-sensing, either a straight-through or crossover cable may be used to connect to a computer. The LAN port LED indicator will light up when a connection is established.

- Step 3: Set up the computer's IP address.

Choose an IP address on the same subnet as the AWK-1121/1127. Since the AWK-1121/1127's default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to 192.168.127.xxx.

NOTE

After you select Maintenance → Load Factory Defaults and click the Activate button, the AWK-1121/1127 will be reset to factory default settings and the IP address will be reset to 192.168.127.253.

- Step 4: Use the web-based manager to configure the AWK-1121/1127

Open your computer's web browser and type http://192.168.127.253 in the address field to access the homepage of the web-based Network Manager. Before the homepage opens, you will need to enter the user name and password as shown in the following figure. For first-time configuration, enter the default user name and password and then click on the Login button:

NOTE

Default user name and password:

User Name: admin

Password: root

For security reasons, we strongly recommend changing the default password. To do so, select Maintenance

→ Password, and then follow the on-screen instructions to change the password.

NOTE

After you click Submit to apply changes the web page will refresh (Updated) will appear on the page and a blinking reminder will be shown on the upper-right corner of the web page:

To activate the changes click Restart and then Save and Restart after you change the settings. About 30 seconds are needed for the AWK-1121/1127 to complete the reboot procedure.

• Step 5: Test communications.

Communication Testing

After installing the AWK-1121/1127 a simple test may be run against an AP to make sure the AWK-1121/1127 has properly established a wireless connection and is functioning normally. In the example below, an AWK-3121 is used as the primary access point.

How to Test an AWK-1121/1127 for Network Connectivity

Connect an AP-configured AWK-3121 (or another access point) to Notebook A. Connect an AWK-1121/1127 to Notebook B. Configure the AWK-1121/1127 and AWK-3121 for the same SSID, and set their IP addresses as below.

graph TD
    Client["Client\nIP: 192.168.127.252"] -->|PING SSID: MOXA| NotebookA["Notebook A\nIP: 192.168.127.2"]
    NotebookA -->|PING SSID: MOXA| NotebookB["Notebook B\nIP: 192.168.127.1"]
    NotebookB -->|PING SSID: MOXA| Client
    NotebookA -->|AP IP: 192.168.127.253| AP

After setting up the testing environment, open a DOS window on notebook B. At the prompt, type:

ping

and then press Enter. A "Reply from IP address ..." response means the communication was successful. A "Request timed out" response means the communication failed. In this case, be sure to first recheck the configuration to make sure the connections are correct.

Wireless Settings

The essential settings for wireless networks are presented in this function group. Settings must be properly set before establishing your wireless network. Familiarize yourself with the following terms before starting the configuration process:

The AWK-1121/1127 as a client can be used as an Ethernet-to-wireless (or LAN-to-WLAN) network adapter. For example, a notebook computer equipped with an Ethernet adaptor but no wireless card can be connected to this device with an Ethernet cable to provide wireless connectivity to another AP.

NOTE

Although it is more convenient to use dynamic bridging, there is a limitation—the AP Client can only transmit IP-based packets between its wireless interface (WLAN) and Ethernet interface (LAN); other types of traffic (such as IPX and AppleTalk) are not forwarded.

Operation Mode

The AWK-1121/1127 is a dedicated WLAN client, so its only operation mode is client. Other client-based operation modes may be added in the future firmware releases.

Wireless Enable

Setting	Description	Factory Default
Enable/Disable	The RF (Radio Frequency) module can be manually turned on or off.Note: This function is only available for firmware version 1.2 and above.	Enable

W LAN

Basic Wireless Settings

The "WLAN Basic Setting Selection" panel is used to edit SSIDs and set the RF type. The RF type selection will configure the AWK-1121/1127 to either the 2.4GHz or 5GHz frequency band. An SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Set the SSID parameter to match that of the APs you wish to connect to, so that the AWK-1121/1127 will associate with network defined by the SSID.

NOTE

Click the "Site Survey" button to view information about available APs, as shown in the following figure. You can click on the SSID of an entity and bring the value of its SSID onto the SSID field of the Basic Wireless Settings page.

Click the Refresh button to re-scan and update the table.

B	Supports IEEE802.11b standard only
G	Supports IEEE802.11g standard only
B/G Mixed	Supports both of IEEE802.11b/g standards, but 802.11g can be slowed down when 802.11b clients are on the network

SSID

Setting	Description	Factory Default
Max. of 31 characters	The SSID must be identical to the target AP for the client and AP to be able to communicate with each other.	MOXA

NOTE

The AWK-1121/1127-JP (for Japanese frequency bands) connects only APs with broadcast (i.e: not hidden) SSIDs, in all IEEE802.11a channels and IEEE802.11g channels 1 to 11. The AWK-1121/1127-EU (for European frequency bands) only connects APs with hidden SSIDs in all IEEE802.11b/g channels.

WLAN Security Settings

The AWK-1121/1127 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2. Several security modes are available in the AWK-1121/1127 by selecting Security mode and WPA type:

• Open: No authentication, no data encryption.
• WEP: Static WEP (Wired Equivalent Privacy) keys must be configured manually.
• WPA/ WPA2-Personal: Also known as WPA/WPA2-PSK. You will need to specify the Pre-Shared Key in the Passphrase field, which will be used by the TKIP or AES engine as a master key to generate keys that actually encrypt outgoing packets and decrypt incoming packets.
• WPA/ WPA2-Enterprise: Also called WPA/WPA2-EAP (Extensible Authentication Protocol). In addition to device-based authentication, WPA/WPA2-Enterprise enables user-based authentication via IEEE802.1X. The AWK-1121/1127 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

Security mode

Setting	Description	Factory Default
Open No authentication	Open
WEP Static WEP is used
WPA	Fully supports IEEE802.11i with “TKIP/AES + 802.1X”
WPA2	Fully supports IEEE802.11i with “TKIP/AES + 802.1X”

Open

For security reasons, you should NOT set security mode to Open (or "Open System"), since authentication and data encryption are NOT performed in Open (or "Open System") mode.

WEP

According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain confidentiality. Shared (or Shared Key) authentication type is used if WEP authentication and data encryption are both needed. Normally, Open (or Open System) authentication type is used when WEP data encryption is run with authentication.

When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-1121/1127 provides 4 entities of WEP key settings that can be selected to use with Key index. The selected key setting specifies the key to be used as a send-key for encrypting traffic from the AP side to the wireless client side. All 4 WEP keys are used as receive-keys to decrypt traffic from the wireless client side to the AP side.

The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit (or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each character uses 4 bits, so a 40-bit key has 10 hex characters, and a 104-bit key has 26 hex characters.

Authentication type

Setting	Description	Factory Default
Open	Data encryption is enabled, but without authentication	Open
Shared	Data encryption and authentication are both enabled.

WPA/ WPA2-Personal

WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method. WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i. The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is regularly changed so that true session is secured.

Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security mode of some wireless APs and clients as well. The AWK-1121/1127 also supports AES algorithms in WPA and WPA2 for better compatibility.

Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (Pre-Shared Key), provide a simple way of encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as possible. There must be at least 8of ASCII characters in the Passphrase, and it could go up to 63. For security reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.

Personal	Provides Pre-Shared Key-enabled WPA and WPA2	Personal
Enterprise	Provides enterprise-level security for WPA and WPA2

Passphrase

Setting	Description	Factory Default
8 to 63 characters	Master key to generate keys for encryption and decryption	None

WPA/ WPA2-Enterprise

When used as a client, the AWK-1121/1127 can support three EAP methods (or EAP protocols): EAP-TLS, EAP-TTLS, and EAP-PEAP, corresponding to WPA/WPA2-Enterprise settings on the AP side.

EAP Protocol

Setting	Description	Factory Default
TLS	Specifies Transport Layer Security protocol	TLS
TTLS	Specifies Tunneled Transport Layer Security
PEAP	Specifies Protected Extensible Authentication Protocol, or Protected EAP

Before choosing the EAP protocol for your WPA/WPA2-Enterprise settings on the client end, please contact the network administrator to make sure the system supports the protocol on the AP end. Detailed information on these three popular EAP protocols is presented in the following sections.

EAP-TLS

TLS is the standards-based successor to Secure Socket Layer (SSL). It can establish a trusted communication channel over a distrusted network. TLS provides mutual authentication through certificate exchange. EAP-TLS is also secure to use. You are required to submit a digital certificate to the authentication server for validation, but the authentication server must also supply a certificate.

You can use Basic Wireless Settings → WLAN Certificate Settings to import your WLAN certificate and enable EAP-TLS on the client end.

EAP-TTLS

It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result, TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication methods.”

TTLS and PEAP work in a similar way. First, they establish a TLS tunnel (EAP-TLS for example), and validate whether the network is trustworthy with digital certificates on the authentication server. This step establishes a tunnel that protects the next step (or "inner" authentication), and consequently is sometimes referred to as "outer" authentication. The TLS tunnel is then used to encrypt an older authentication protocol that authenticates the user for the network.

As you can see, digital certificates are still needed for outer authentication in a simplified form. Only a small number of certificates are required, which can be generated by a small certificate authority. Certificate reduction makes TTLS and PEAP much more popular than EAP-TLS.

The AWK-1121/1127 provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP, and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they may be useful as inner authentication methods with TTLS and PEAP.

Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an anonymous user name for the outer authentication, with the true user name only shown through the encrypted channel. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network administrator before you enable identity hiding in TTLS and PEAP.

PEAP

There are a few differences in the TTLS and PEAP inner authentication procedures. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The AWK-1121/1127 provides MS-CHAP-V2 merely as an EAP method for inner authentication.

Advanced Settings

Several advanced functions are available to increase the functionality of your AWK-1121/1127 and wireless network system. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the AWK-1121/1127 supports SNMP, making network management easier.

Packet Filters

The AWK-1121/1127 includes various filters for IP-based packets going through LAN and WLAN interfaces. You can set these filters as a firewall to help enhance network security.

MAC Filter

The AWK-1121/1127's MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified MAC addresses. The AWK-1121/1127 provides 8 entities for setting MAC addresses in your filtering policy. Remember to check the Active check box for each entity to activate the setting.

Enable

Setting	Description	Factory Default
Enable	Enables MAC filter	Disable
Disable Disables MAC filter

Policy

Setting	Description	Factory Default

Drop Any packet fitting	the entities on list will be denied.

ATTENTION

Be careful when you enable the filter function:

Drop + "no entity on list is activated" = all packets are allowed

Accept + "no entity on list is activated" = all packets are denied

IP Protocol Filter

The AWK-1121/1127's IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with specified IP protocol and source/destination IP addresses.

The AWK-1121/1127 provides 8 entities for setting IP protocol and source/destination IP addresses in your filtering policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source IP or the Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a range of IP addresses to accept or drop. For example, "IP address 192.168.1.1, netmask 255.255.255.255" refers to a sole IP address, while "IP address 192.168.1.1, netmask 255.255.255.0" refers to the range of IP addresses from 192.168.1.1 to 192.168.254. Remember to check the Active check box for each entity to activate the setting.

ATTENTION

Be careful when you enable the filter function:

Drop + "no entity on list is activated" = all packets are allowed.

Accept + "no entity on list is activated" = all packets are denied.

TCP/ UDP Port Filter

The AWK-1121/1127's TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets with a specified source or destination port.

The AWK-1121/1127 provides 8 entities for setting the range of source/destination ports of a specific protocol. In addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end port can be left empty if only a single port is specified. Of course, the end port cannot be larger then the start port.

The Application name is a text string that describes the corresponding entity with up to 31 characters.

Remember to check the Active check box for each entity to activate the setting.

Be careful when you enable the filter function:

Drop + "no entity on list is activated" = all packets are allowed

Accept + "no entity on list is activated" = all packets are denied

SNMP Agent

The AWK-1121/1127 supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means that SNMP servers access all objects with read-only or read/write permissions using the community string public/private (default value). SNMP V3, which requires you to select an authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to enhance data security.

The AWK-1121/1127's MIB can be found in the software CD and supports reading the attributes via SNMP. (Only get method is supported.)

SNMP security modes and security levels supported by the AWK-1121/1127 are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager.

Protocol Version	Setting on UI web page	Authentication Type	Data Encryption	Method
SNMP V1, V2c	V1, V2c Read Community	Community string	No	Use a community string match for authentication
	V1, V2c Write/Read Community	Community string	No	Use a community string match for authentication
SNMP V3	No-Auth	No	No	Use account with admin or user to access objects

Link Fault Pass-Through

This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once Ethernet link is recovered, AWK-1121/1127 will try to connect to AP.

If wireless is disconnected, AWK-1121/1127 restarts auto-negotiation on Ethernet port but always stays in the link failure state. Once the wireless connection is recovered, AWK-1121/1127 will try to recover the Ethernet link.

System log will indicate the link fault pass through events in addition to the original link up/down events.

Serial Port Settings (AWK-1127 Only)

The AWK-1127 not only is capable of bring Ethernet devices onto the WLAN network, it also has a serial port for additional connectivity for serial devices. The AWK support various useful serial operation modes to make connecting to your serial devices much simpler.

Operation Modes

The Operation Modes page for the serial port is where you can configure the serial port operation mode and related settings.

Application

This field specifies what kind application you will be using for this serial port. Depending on the application, different operation modes and related settings will be displayed.

Setting	Description	Factory Default
Disable	This serial port will be disabled.	Disable
Device Control	This serial port will be used to control a device using legacy software installed on a Windows, Linux, or UNIX system.Drivers will need to be installed that will allow your software to communicate with the device as if it were physically attached to a local COM or TTY port. You may select between RealCOM and RFC2217 operation modes.
Socket	This serial port will be used for a TCP or UDP socket-based application. You may select between TCP Client, TCP Server, and UDP operation modes.

Mode

Along with Application, this field specifies the serial port's operation mode, or how it will interact with network devices. Depending on how Application is configured, different options are available for Mode. Depending on how Mode is configured, additional settings will be available for configuration.

Setting	Description	Factory Default
RealCOM	This serial port will operate in RealCOM mode.	(depends on Application)
RFC2217 This serial port will operate in RFC2217 mode.
TCP Server	This serial port will operate in TCP Server mode.
TCP Client This serial port will operate in TCP Client mode.
UDP This serial port will operate in UDP mode.

RealCOM Mode

RealCOM mode is designed to work with AWK drivers that are installed on a network host. COM drivers are provided for Windows systems, and TTY drivers are provided for Linux and UNIX systems. The driver establishes a transparent connection to the attached serial device by mapping a local serial port to the AWK-1127 serial port. RealCOM mode supports up to four simultaneous connections, so multiple hosts can collect data from the attached device at the same time.

    note right of A: Proceed directly with data transmission (connection request not required)

ATTENTION

RealCOM drivers are installed and configured through OnCell Windows Driver Manager.

RealCOM mode allows you to continue using your serial communications software to access devices that are now attached to your AWK-1127. On the host, the AWK RealCOM driver automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirects it to the network. At the other end of the connection, the AWK-1127 accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the appropriate device.

ATTENTION

In RealCOM mode, two hosts can have simultaneous access control over the AWK-1127 serial port.

When Mode is set to RealCOM on a serial port's Operation Modes page, you will be able to configure additional settings such as TCP alive check time, Max connection, and Ignore jammed IP.

TCP Alive Check Time

Setting	Description	Factory Default
0 to 99 min.	This field specifies how long the AWK-1127 will wait for a response to “keep alive” packets before closing the TCP connection. The AWK-1127 checks connection status by sending periodic “keep alive” packets.0: The TCP connection will remain open even if there is no response to the “keep alive” packets.1 to 99: If the remote host does not respond to the packet within the specified time, the AWK-1127 will force the existing TCP connection to close.	7 min.

Max Connection

This field specifies the maximum number of connections that will be accepted by the serial port.

Setting	Description	Factory Default
1 or 2	1: Only one specific host can access this serial port, and the RealCOM driver on that host will have full control over the port.2: This serial port will allow the two connections to be opened simultaneously. With simultaneous connections, the RealCOM driver will only provide a pure data tunnel with no control ability. The serial communication will be determined by the AWK-1127 rather than by your application program.Application software that is based on the RealCOM driver will receive a driver response of “success” when using any of the Win32 API functions. The AWK-1127 will send data only to the RealCOM driver on the host. Data received from hosts will be sent to the attached serial device on a first-in-first-out basis.	1

ATTENTION

When Max connection is 2, the serial port's communication settings (i.e., baudrate, parity, data bits, etc.) will be determined by the AWK-1127. Any host that opens the COM port connection must use identical serial communication settings.

Ignore Jammed IP

This field specifies how an unresponsive IP address is handled when there are simultaneous connections to the serial port.

Setting	Description	Factory Default
Disable	All transmission will be suspended if one IP address becomes unresponsive. Transmission will only resume when all hosts have responded.	Disable
Enable	Data transmission to the other hosts will not be suspended if one IP address becomes unresponsive.

Allow Driver Control

This field specifies how the port will proceed if driver control commands are received from multiple hosts that are connected to the port.

Setting	Description	Factory Default
Disable	Driver control commands will be ignored.	Disable
Enable Control commands will be accepted, with the most recent command received taking precedence.

Connection Goes Down

This field specifies what happens to the RTS and DTR signals when the Ethernet connection goes down. For some applications, serial devices need to know the Ethernet link status through RTS or DTR signals sent through the serial port.

Setting	Description	Factory Default
always low	The selected signal will change to low when the Ethernet connection goes down.	always high
always high The selected	signal will remain high when the Ethernet connection goes down.

Packet Length

This field specifies the maximum amount of data that is allowed to accumulate in the serial port buffer before sending.

Setting	Description	Factory Default
0 to 1024	0: Packet length is disregarded and data in the buffer will be sent as specified by the delimiter settings or when the buffer is full.1 to 1024: Data in the buffer will be sent as soon it reaches the specified length.	0

Delimiter 1 and 2

These fields are used to define special delimiter character(s) for data packing. Enable Delimiter 1 to control data packing with a single character; enable both Delimiter 1 and 2 to control data packing with two characters received in sequence.

Setting	Description	Factory Default
Enable	When these fields are enabled, serial data will accumulate in the serial port's buffer until the buffer is full or until the specified delimiter character(s) are received. For example, the carriage return character could be used as a delimiter in order to transmit each sentence or paragraph in a separate packet. Data will be packed according to Delimiter process.Delimiters must be incorporated into the data stream at the software or device level. The Delimiter value can be set ranging from 00 to FF.	Unchecked

ATTENTION

When Delimiter 1 is enabled, Packet length must be set to 0.

Delimiter Process

This field specifies how data is packed when delimiter characters are received. This field has no effect if Delimiter 1 is not enabled.

Setting	Description	Factory Default
Do Nothing	Data accumulated in the serial port's buffer will be packed, including delimiters.	Do Nothing
Delimiter + 1	One additional character must be received before the data in the serial port's buffer is packed.
Delimiter + 2	Two additional characters must be received before the data in the serial port's buffer is packed.
Strip Delimiter	Data accumulated in the serial port's buffer will be packed, but the delimiter character(s) will be stripped from the data.

Force Transmit

This field controls data packing by the amount of time that elapses between bits of data. When using this field, make sure that Inactivity time is disabled or set to a larger value. Otherwise the connection may be closed before the data in the buffer can be transmitted.

Setting	Description	Factory Default
0 to 65535	0: If serial data is received, setting this value to 0 means no data will be buffered and all data will be transmitted immediately as received.1 to 65535: If serial data is not received for the specified amount of time, the data that is currently in the buffer will be packed for network transmission. The optimal force transmit time depends on your application, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is 8.3 ms, so the force transmit time to be larger than 8.3 ms.	0 ms

RFC2217 Mode

RFC2217 mode is similar to RealCOM mode, since it relies on a driver to transparently map a virtual COM port on a host computer to a serial port on the AWK-1127. The RFC2217 standard defines general COM port control

options based on the Telnet protocol and supports one connection at a time. Third party drivers supporting RFC2217 are widely available on the Internet and can be used to implement virtual COM mapping.

TCP Server Mode

In TCP Server mode, the AWK-1127 serial port is assigned an IP:port address that is unique on your TCP/IP network. It waits for the host computer to establish a connection to the attached serial device. This operation mode also supports up to four simultaneous connections, so multiple hosts can collect data from the attached device at the same time.

Data transmission proceeds as follows:

1. A host requests a connection to the AWK-1127 serial port.
2. Once the connection is established, data can be transmitted in both directions—from the host to the device, and from the device to the host.

0 to 65535	This field controls data packing by the amount of time that elapses between bits of data. When using this field, make sure that Inactivity time is disabled or set to a larger value.Otherwise the connection may be closed before the data in the buffer can be transmitted.0: If serial data is received, setting this value to 0 means no data will be buffered and all data will be transmitted immediately as received.1 to 65535: If serial data is not received for the specified amount of time, the data that is currently in the buffer will be packed for network transmission. The optimal force transmit time depends on your application, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is 8.3 ms, so the force transmit time to be larger than 8.3 ms.	0 ms

UDP Mode

UDP is similar to TCP but is faster and more efficient. Data can be broadcast to or received from multiple network hosts. However, UDP does not support verification of data and would not be suitable for applications where data integrity is critical. It is ideal for message display applications.

Auto Warning Settings

Since industrial-grade devices are often located at the endpoints of a system, these devices will not always know what is happening elsewhere on the network. This means that these devices, including wireless APs or clients, must provide system maintainers with real-time alarm messages. Even when system administrators are out of the control room for an extended period, they can still be informed of the status of devices almost instantaneously when exceptions occur.

In addition to logging these events, the AWK-1121/1127 supports different approaches to warn engineers automatically, such as SNMP trap or e-mail.

Trap

Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven notification can make your network more efficient.

Because a management station usually takes care of a large number of devices that have a large number of objects, it will be overloading for the management station to poll or send requests to query every object on every device. It would be better if the managed device agent could notify the management station by sending a message known as a trap for the event.

Ping helps to diagnose the integrity of wired or wireless networks. By inputting a node's IP address in the Destination field, you can use the ping command to make sure it exists and whether or not the access path is available.

If the node and access path are available, you will see that all packets were successfully transmitted with no loss. Otherwise, some, or even all, packets may get lost, as shown in the following figure.

Firmware Upgrade

The AWK-1121/1127 can be enhanced with more value-added functions by installing firmware upgrades. The latest firmware is available at Moxa's download center.

Before running a firmware upgrade, make sure the AWK-1121/1127 is off-line. Click the Browse button to specify the firmware image file and click Firmware Upgrade and Restart to start the firmware upgrade. After the progress bar reaches 100%, the AWK-1121/1127 will reboot itself.

When upgrading your firmware, the AWK-1121/1127's other functions are forbidden.

ATTENTION

Please make sure the power source is stable when you upgrade your firmware. An unexpected power breakup may damage your AWK-1121/1127.

Config Import/ Export

You can back up or restore the AWK-1121/1127's configuration with Config Import/Export.

In the Config Import section, click Browse to specify the configuration file and click Config Import button to begin importing the configuration.

In the Config Export section, click the Config Export button and save the configuration file onto your local storage media. The configuration file is a text file and you can view and edit it with a general text-editing tool.

You can also do automated device back ups or setup restoration using Moxa's dedicated configuration import-export accessory, the ABC-01 (HW Rev. 1.1 support only).

To download the configuration to the AWK device:

1. Turn off the AWK device.
2. Plug in the ABC-01 to the AWK's console, via the RS-232 port.
3. Turn on the AWK device.
4. The AWK device will automatically detect the ABC-01 during the boot process, and will automatically download the configuration file from the ABC-01 to the AWK. Once the configuration downloads, then-if the configuration format is correct-the AWK will emit three short beeps and continue the boot process.
5. Once the AWK has booted up successfully, it will emit the normal two beeps and the "Ready" LED will turn to solid green.

Loading Factory Defaults

Use this function to reset the AWK-1121/1127 and roll all settings back to the factory default values. You can also reset the hardware by pressing the reset button on the rear panel of the AWK-1121/1127.

Password

You can change the administration password for each of the AWK-1121/1127's console managers by using the Password function. Before you set up a new password, you must input the current password and reenter the new password for confirmation. For your security, do not use the default password root, and remember to change the administration password regularly.

Additional settings to help you manage your AWK-1121/1127, are available on this page.

Setting	Description	Factory Default
Always enabled	The AWK-1121/1127's Reset button works normally.	Always enabled
Disabled 60 sec after boot-up	The AWK-1121/1127's “reset to defaults” function will go inactive 60 seconds after the AWK-1121/1127 finishes booting up.

Save Configuration

The following figure shows how the AWK-1121/1127 stores the setting changes into volatile and non-volatile memory. All data stored in volatile memory will disappear when the AWK-1121/1127 is shutdown or rebooted unless they are saved in non-volatile memory. Because the AWK-1121/1127 starts up and initializes with the settings stored in flash memory, all new changes must be saved to flash memory before restarting the AWK-1121/1127.

This also means that new changes will not take effect unless you press the "Save and Restart" button.

OnCell Windows Driver Manager

The AWK-1127 uses the same RealCom serial driver as Moxa's OnCell cellular gateways. The below section describes how to use the OnCell Windows Driver Manager to create a virtual COM port for the AWK-1127 in RealCom mode.

Installing OnCell Windows Driver Manager

OnCell Windows Driver Manager is intended for use with AWK-1127 serial ports that are set to RealCOM mode. The software manages the installation of drivers that allow you to map unused COM ports on your PC to serial ports on the AWK-1127. These drivers are designed for use with Windows

98/ME/NT/2000/XP/2003/Vista/2008. When the drivers are installed and configured, devices that are attached to serial ports on the AWK-1127 will be treated as if they were attached to your PC's own COM ports.

1. Click the INSTALL COM Driver button in the OnCell Installation CD auto-run window to install the OnCell Windows Driver. Once the installation program starts running, click Yes to proceed.
2. Click Next when the Welcome screen opens, to proceed with the installation.

Click Next to install program files to the default directory, or click Browse to select an alternate location.

1. Click Next to install the program's shortcuts in the appropriate Start Menu folder.
2. Click Next to proceed with the installation. The installer then displays a summary of the installation options.

On Windows XP, the installer will display a message that the software has not passed Windows Logo testing. This is shown as follows:

Click Continue Anyway to finish the installation.

1. Click Finish to complete the installation of the OnCell Windows Driver Manager.

Using OnCell Windows Driver Manager

After you install OnCell Windows Driver Manager, you can set up the AWK-1127's serial ports as remote COM ports for your PC host. Make sure that the serial port(s) on your AWK-1127 are set to RealCOM mode when mapping COM ports with OnCell Windows Driver Manager.

1. Go to Start → OnCell Windows Driver Manager → OnCell Windows Driver Manager to start the COM mapping utility.
2. Click the Add icon.

1. Click Rescan to search for the AWK-1127. From the list that is generated, select the server that you will map COM ports to, and then click OK.

Alternatively, for RealCOM mode, you can select Input Manually and then manually enter the AWK-1127 's IP Type. To do this, select LAN type, followed by 1st Data Port, and 1st Command Port for the COM ports that will be mapped to. Click OK to proceed to the next step. Note that the Add OnCell page supports FQDN (Fully Qualified Domain Name), in which case the IP address will be filled in automatically.

1. COM ports and their mappings will appear in blue until they are activated. Activating the COM ports saves the information in the host system registry and makes the COM port available for use. The host computer will not have the ability to use the COM port until the COM ports are activated. Click Yes to activate the COM ports at this time, or click Cancel to activate the COM ports later.

1. When using Windows XP, a message is displayed during the activation of each port, indicating that the software has not passed Windows Logo certification. Click Continue Anyway to proceed.

1. Ports that have been activated will appear in black.

1. Click on the created COM port to select it. Then right click to select Basic Setting tab. On the Basic Setting tab, use the COM Number drop-down list to select a COM number to be assigned to the AWK-1127's serial port that is being configured. Note that ports that are "in use" will be labeled accordingly.

1. Click the Advanced Setting tab to modify Tx Mode, FIFO, Fast Flush, and other parameters.

Tx Mode

Hi-Performance is the default for Tx mode. After the driver sends data to the AWK-1127, the driver immediately issues a "Tx Empty" response to the program. Under Classical mode, the driver will not send the "Tx Empty" response until after confirmation is received from the AWK-1127's serial port. This causes lower throughput. Classical mode is recommended if you want to ensure that all data is sent out before further processing.

FI FO

If FIFO is Disabled, the AWK-1127 will transmit one byte at a time when the Tx FIFO becomes empty, and an Rx interrupt will be generated for each incoming byte. This will result in a faster response and lower throughput.

Network Timeout

You can use this option to prevent blocking if the target OnCell is unavailable.

Auto Network Re-Connection

With this option enabled, the driver will repeatedly attempt to re-establish the TCP connection if the AWK-1127 does not respond to background "check alive" packets.

Return error if network is unavailable

If this option is disabled, the driver will not return any error even when a connection cannot be established to the AWK-1127. With this option enabled, calling the Win32 Comm function will result in the error return code "STATUS_NETWORK_UNREACHABLE" when a connection cannot be established to the AWK-1127. This usually means that your host's network connection is down, perhaps due to a cable being disconnected.

However, if you can reach other network devices, it may be that the AWK-1127 is not powered on or is disconnected. Note that Auto Network Re-Connection must be enabled in order to use this function.

Fast Flush (only flushes the local buffer)

For some applications, the user's program will use the Win32 "PurgeComm()" function before it reads or writes data. After a program uses this PurgeComm() function, the OnCell driver continues to query the OnCell's firmware several times to make sure no data is queued in the OnCell firmware buffer, rather than just flushing the local buffer. This design is used to satisfy some special considerations. However, it may take more time (about several hundred milliseconds) than a native COM1 due to the additional time spent communicating across the Ethernet. This is why PurgeComm() works significantly faster with native COM ports on the PC than with mapped COM ports on the AWK-1127. In order to accommodate other applications that require a faster response time, the new OnCell driver implements a new Fast Flush option. By default, this function is enabled.

If you have disabled Fast Flush and find that COM ports mapped to the AWK-1127 perform markedly slower than when using a native COM port, try to verify if "PurgeComm()" functions are used in your application. If so, try enabling the Fast Flush function and see if there is a significant improvement in performance.

Auto IP Report: The functions applies to OnCell Series only and does not apply to the AWK-1127.

1. The Serial Parameters tab in the following figure show the default settings when the AWK-1127 is powered on. However, the program can redefine the serial parameters to different values after the program opens the port with Win32 API.

1. Click the Security tab to configure security settings. Select the Enable Data Encryption option to enable data to be encrypted when transmitted over the COM ports. After selecting the encryption option, select the Keep connection option to start encrypting COM port communications immediately without restarting the COM ports. (If your application opens and closes COM ports frequently and the AWK-1127 is only for one host, you can enable this option to speed up the opening/closing time. However, this will result in your host tying up the COM port so that other hosts cannot use it.).

1. To save the configuration to a text file, select Export from the COM Mapping menu. You will then be able to import this configuration file to another host and use the same COM Mapping settings in the other host.

Moxa OnCell Linux Real TTY Driver

The AWK-1127 uses the same Real TTY serial driver as Moxa's OnCell cellular gateways. The below section describes how to use the OnCell Linux Real TTY Driver to map a virtual tty port for the AWK-1127.

Basic Procedure

To map an AWK-1127 serial port to a Linux host's tty port, follow these instructions:

1. Set up the AWK-1127. After verifying that the IP configuration works and you can access the AWK-1127 (by using ping, telnet, etc.), configure the desired serial port on the AWK-1127 to RealCOM mode.
2. Install the Linux Real TTY driver files on the host.
3. Map the AWK-1127 serial port to the host's tty port.

Hardware Setup

Before proceeding with the software installation, make sure you have completed the hardware installation. Note that the default IP address for the LAN interface of AWK-1127 is 192.168.127.253.

NOTE After installing the hardware, you must configure the operation mode of the serial port on your AWK-1127 to RealCOM mode.

Installing Linux Real TTY Driver Files

1. Obtain the driver file from the included CD-ROM or the Moxa website, at http://www.moxa.com.
2. Log in to the console as a super user (root).
3. Execute cd / to go to the root directory.
4. Copy the driver file moxa_oncell_realty.tgz to the / directory.
5. Execute tar xvfz moxa_oncell_realty.tgz to extract all files into the system.
6. Execute / tmp/ oncell_realty/ mxinst.

For RedHat AS/ES/WS and Fedora Core1, append an extra argument as follows:

# / tmp/ oncell_realty/ mxinst SP1

The shell script will install the driver files automatically.

1. After installing the driver, you will be able to see several files in the /usr/lib/oncell_realty/driver folder:

mxaddsvr (Add Server, mapping tty port)
mxdelsvr (Delete Server, un-mapping tty port)
mxloadsvr (Reload Server)
mxmknod (Create device node/tty port)
mxrmnod (Remove device node/tty port)
mxuninst (Remove tty port and driver files)
At this point, you will be ready to map the AWK-1127 serial port to the system tty port.

Mapping TTY Ports

Make sure that you set the operation mode of the desired AWK-1127 serial port to RealCOM mode. After logging in as a super user, enter the directory /usr/lib/oncell_realty/driver and then execute mxaddsvr to map the target OnCell serial port to the host tty ports. The syntax of mxaddsvr is as follows:

mxaddsvr [OnCell IP Address] [Total Ports] ([Data port] [Cmd port])

The mxaddsvr command performs the following actions:

1. Modifies oncellreald.cf.
2. Creates tty ports in directory /dev with major & minor number configured in oncellreald.cf.
3. Restarts the driver.

Mapping tty ports automatically

To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as in the following example:

<h1 id="cd-usrliboncell_realtydriver">cd /usr/lib/oncell_realty/driver</h1>
<h1 id="mxaddsvr-19216834-1">./mxaddsvr 192.168.3.4 1</h1>

In this example, one tty port will be added, with IP 192.168.3.4, with data port 950 and command port 966.

Mapping tty ports manually

To map tty ports manually, you may execute mxaddsvr and manually specify the data and command ports, as in the following example:

<h1 id="cd-usrliboncell_realtydriver-2">cd /usr/lib/oncell_realty/driver</h1>
<h1 id="mxaddsvr-19216834-1-4001-966">./mxaddsvr 192.168.3.4 1 4001 966</h1>

In this example, one tty port will be added, with IP 192.168.3.4, with data port 4001 and command port 966.

Removing Mapped TTY Ports

After logging in as root, enter the directory / usr/lib/oncell_realty/driver and then execute mxdelsvr to delete a server. The syntax of mxdelsvr is:

mxdelsvr [IP Address] 

Example:

<h1 id="cd-usrliboncell_realtydriver-3">cd /usr/lib/oncell_realty/driver</h1>
<h1 id="mxdelsvr-19216834">./mxdelsvr 192.168.3.4</h1>

The following actions are performed when executing mxdelsvr:

1. Modify oncellreald.cf.
2. Remove the relevant tty ports in directory /dev.
3. Restart the driver.

If the IP address is not provided in the command line, the program will list the installed servers and total ports on the screen. You will need to choose a server from the list for deletion.

Removing Linux Driver Files

A utility is included that will remove all driver files, mapped tty ports, and unload the driver. To do this, you only need to enter the directory / usr/ lib/ oncell_realty/ driver, then execute mxuninst to uninstall the driver. This program will perform the following actions:

1. Unload the driver.
2. Delete all files and directories in / usr/ lib/ moxa_oncell
3. Delete directory / usr/lib/moxa_oncell
4. Modify the system initializing script file.

Moxa OnCell UNIX Fixed TTY Driver

Installing the UNIX Driver

1. Log in to UNIX and create a directory for the Moxa TTY. To create a directory named /usr/etc, execute the command:

<h1 id="mkdir-p-usretc">mkdir -p /usr/etc</h1>

1. Copy moxa_oncell_fixedtty.tar to the directory you created. If you created the /usr/ etc directory above, you would execute the following commands:

<h1 id="cp-moxa_oncell_fixedttytar-usretc">cp moxa_oncell_fixedtty.tar /usr/etc</h1>
<h1 id="cd-usretc">cd /usr/etc</h1>

1. Extract the source files from the tar file by executing the command:

<h1 id="tar-xvf-moxa_oncell_fixedttytar">tar xvf moxa_oncell_fixedtty.tar</h1>

The following files will be extracted:

README.TXT

oncellttyd.c --- source code

oncellttyd.cf --- an empty configuration file

Makefile --- makefile

VERSION.TXT --- fixed tty driver version

FAQ.TXT

1. Compile and Link

For SCO UNIX:

# make sco

For UnixWare 7:

# make svr5

For UnixWare 2.1.x, SVR4.2:

# make svr42

Configuring the UNIX Driver

Modify the configuration

The configuration used by the oncellttyd program is defined in the text file oncellttyd.cf, which is in the same directory that contains the program oncellttyd. You may use vi, or any text editor to modify the file, as follows:

ttyp1 192.168.1.1 950

For more configuration information, view the file oncellttyd.cf, which contains detailed descriptions of the various configuration parameters.

NOTE

The "Device Name" depends on the OS. See the Device Naming Rule section in README.TXT for more information.

To start the oncellttyd daemon after system bootup, add an entry into /etc/inittab, with the tty name you configured in oncellttyd.cf, as in the following example:

ts:2:respawn:/usr/etc/oncell_fixedtty/oncellttyd -t 1

Device naming rule

For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use:

pts/[n]

For all other UNIX operating systems, use:

ttyp[n]

Starting moxattyd

Execute the command init q or reboot your UNIX operating system.

Adding an additional server

1. Modify the text file oncellttyd.cf to add an additional server. User may use vi or any text editor to modify the file. For more configuration information, look at the file oncellttyd.cf, which contains detailed descriptions of the various configuration parameters.

2. Find the process ID (PID) of the program oncellttyd.

<h1 id="ps-ef-grep-oncellttyd">ps -ef | grep oncellttyd</h1>

1. Update configuration of oncellttyd program.

<h1 id="kill-usr1-pid">kill -USR1 [PID]</h1>

(e.g., if oncellttyd PID = 404, kill -USR1 404) 

This completes the process of adding an additional server.

This chapter explains how to access the AWK-1121/1127 for the first time. In addition to HTTP access, there are four ways to access AWK-1121/1127: serial console, Telnet console, SSH console, and HTTPS console. The serial console connection method, which requires using a short serial cable to connect the AWK-1121/1127 to a PC's COM port, can be used if you do not know the AWK-1121/1127's IP address. The other consoles can be used to access the AWK-1121/1127 over an Ethernet LAN, or over the Internet.

The following topics are covered in this chapter:

☐ RS-232 Console Configuration (115200, None, 8, 1, VT100)
☐ Configuration by Telnet and SSH Consoles
☐ Configuration by Web Browser with HTTPS/ SSL
□ Disabling Telnet and Browser Access

RS-232 Console Configuration (115200, None, 8, 1, VT100)

The serial console connection method, which requires using a short serial cable to connect the AWK-1121/1127 to a PC's COM port, can be used if you do not know the AWK-1121/1127's IP address. It is also convenient to use serial console configurations when you cannot access the AWK-1121/1127 over Ethernet LAN, such as in the case of LAN cable disconnections or broadcast storming over the LAN.

ATTENTION

Do not use the RS-232 console manager when the AWK-1121/1127 is powered at reversed voltage (ex. -48VDC), even though reverse voltage protection is supported.

If you need to connect the RS-232 console at reversed voltage, Moxa's TCC-82 isolator is your best solution.

NOTE

We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge from Moxa's website.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the AWK-1121/1127's RS-232 console port to your PC's COM port (generally COM1 or COM2, depending on how your system is set up). After installing PComm Terminal Emulator, take the following steps to access the RS-232 console utility.

1. From the Windows desktop, open the Start menu and start PComm Terminal Emulator in the PComm (Lite) group.
2. Select Open under Port Manager to open a new connection.

1. The Communication Parameter page of the Property window opens. Select the appropriate COM port for Console Connection, 115200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits. Click on the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue.

1. The Console login screen will appear. Log into the RS-232 console with the login name (default: admin) and password (default: root, if no new password is set).

1. The AWK-1121/1127's device information and Main Menu will be displayed. Please follow the description on screen and select the administration option you wish to perform.

NOTE To modify the appearance of the PComm Terminal Emulator window, select Edit Font and then choose the desired formatting options.

ATTENTION

If you unplug the RS-232 cable or trigger DTR, a disconnection event will be evoked to enforce logout for network security. You will need to log in again to resume operation.

Configuration by Telnet and SSH Consoles

You may use Telnet or SSH client to access the AWK-1121/1127 and manage the console over a network. To access the AWK-1121/1127's functions over the network from a PC host that is connected to the same LAN as the AWK-1121/1127, you need to make sure that the PC host and the AWK-1121/1127 are on the same logical subnet. To do this, check your PC host's IP address and subnet mask.

NOTE The AWK-1121/1127's default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0 (for a Class C network). If you do not set these values properly, please check the network settings of your PC host and then change the IP address to 192.168.127.xxx and subnet mask to 255.255.255.0.

Follow the steps below to access the console utility via Telnet or SSH client.

1. From Windows Desktop, run Start → Run, and then use Telnet to access the AWK-1121/1127's IP address from the Windows Run window (you may also issue the telnet command from the MS-DOS prompt).

1. When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the AWK-1121/1127's IP address, specifying 22 for the SSH connection port.

1. The Console login screen will appear. Please refer to the previous paragraph "RS-232 Console Configuration" and for login and administration.

Configuration by Web Browser with HTTPS/ SSL

To secure your HTTP access, the AWK-1121/1127 supports HTTPS/SSL encryption for all HTTP traffic. Perform the following steps to access the AWK-1121/1127's web browser interface via HTTPS/SSL.

1. Open your web browser and type https:// in the address field. Press Enter to establish the connection.

1. Warning messages will pop out to warn users that the security certificate was issued by a company they have not chosen to trust.

1. Select Yes to accept the certificate issued by Moxa IW and then enter the AWK-1121/1127's web browser interface secured via HTTPS/SSL. (You can see the protocol in URL is https.) Then you can use the menu tree on the left side of the window to open the function pages to access each of AWK-1121/1127's functions.

Disabling Telnet and Browser Access

If you are connecting the AWK-1121/1127 to a public network but do not intend to use its management functions over the network, then we suggest disabling both Telnet Console and Web Configuration. Please run Maintenance → Console Settings to disable them, as shown in the following figure.

Console Settings

HTTP console	○ Enable ○ Disable
HTTPS console	○ Enable ○ Disable
Telnet console	○ Enable ○ Disable
SSH console	○ Enable ○ Disable

This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you administer your AWK-1121/1127s and plan your industrial wireless network better.

The following topics are covered in this appendix:

Fragment
□ RTS threshold

Fragment

A lower setting means smaller packets, which will create more packets for each transmission. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications of this value are recommended.

RTS threshold

RTS threshold (256-2346) – This setting determines how large a packet can be before the Access Point coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2,346. When you encounter inconsistent data flow, only minor modifications are recommended.
