Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE LED starts
blinking green. Release the button to reset the AWK-3131A.
Relay (Digital Output)
The AWK-3131A has one relay output consisting of the 2 terminal block contacts on the top panel, as shown
below. These relay contacts are used to forward system failures and user-configured events.
The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered.
If a user-configured event does not occur, the relay circuit will remain closed. For safety reasons, the relay
circuit is kept open when the AWK-3131A is not powered up.

AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data.
Client: When the AWK-3131A is configured for Client mode, it can be used as an Ethernet-to-wireless (or
LAN-to-WLAN) network adaptor. 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.

WLAN Security Settings
The AWK-3131A 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 AWK3131A 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-3131A can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

Web Console Configuration
Open
For security reasons, you should NOT set security mode to Open System, since authentication and data
encryption are NOT performed in Open System mode.
WEP (only for legacy mode)
NOTE
Moxa includes WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully
deprecated by the Wi-Fi alliance. We do not recommend the use of WEP security under any circumstances.
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-3131A
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 40bit (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 128-bit key has 26 characters.

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-3131A also supports AES algorithms in WPA and
WPA2 for better compatibility.
Personal versions of WPA/WPA2, also know 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 8 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.

NOTE
Web Console Configuration
The key renewal value dictates how often the wireless AP encryption keys should be changed. The security
level is generally higher if you set the key renewal value to a shorter number, which forces the encryption
keys to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods
can be considered if the line is not very busy.
WPA/WPA2-Enterprise (for AP/Master mode)
By setting WPA type to Enterprise, you can use EAP (Extensible Authentication Protocol), a framework
authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security
modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X
functionality is enabled in WPA /WPA2. The IEEE 802.1X protocol also offers the possibility of carrying out
an efficient connection authentication on a large-scale network. It is not necessary to exchange keys or
passphrases.

Before choosing the EAP protocol for your WPA/WPA2-Enterpise 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.
You can check the current certificate status in Current Status if it is available.

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-3131A provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP, and MSCHAP-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.

inner authentication.

Advanced Settings
Several advanced functions are available to increase the functionality of your AWK-3131A and wireless
network system. A VLAN is a collection of clients and hosts grouped together as if they were connected to
the broadcast domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently.
Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the
AWK-3131A can support STP/RSTP protocol to increase reliability across the entire network, and SNMP
support can make network management easier.
Using Virtual LAN
Setting up Virtual LANs (VLANs) on your AWK series increases the efficiency of your network by dividing the
LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that
communicate as if they were attached to the same broadcast domain, regardless of their physical location. A
VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if
they are not located on the same network switch. Network reconfiguration can be done through software
instead of physically relocating devices.
VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless
sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP
configured to support its assigned SSID/VLAN.
Benefits of VLANs
VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:
•
Manage adds, moves, and changes from a single point of contact
•
Define and monitor groups
•
Reduce broadcast and multicast traffic to unnecessary destinations
•
Improve network performance and reduce latency
•
Increase security
•
Secure network restricts members to resources on their own VLAN
•
Clients roam without compromising security
VLAN Workgroups and Traffic Management
The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per
radio interface, with a unique VLAN configurable per SSID.
The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic
received by a VLAN is only sent on the wireless interface associated with that same VLAN. This eliminates
unnecessary traffic on the wireless LAN, conserving bandwidth and maximizing throughput.
In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of wireless
users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for example, one
VLAN could be used for a marketing department and the other for a human resource department.
In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified as
marketing or human resource, depending on which wireless client received it. The AP would insert VLAN headers or
“tags” with identifiers into the packets transmitted on the wired backbone to a network switch.
3-20
AirWorks AWK-3131A
Web Console Configuration
Finally, the switch would be configured to route
packets from the marketing department to the
appropriate corporate resources such as printers
and servers. Packets from the human resource
department could be restricted to a gateway that
allowed access to only the Internet. A member of
the human resource department could send and
receive e-mail and access the Internet, but would
be prevented from accessing servers or hosts on the
local corporate network.

NOTE
Web Console Configuration
The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a
VLAN ID, then those wireless clients who are members of that VLAN will have AP management access.
CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN IDs on the AP,
all members of that User VLAN will have management access to the AP. Be careful to restrict VLAN
membership to those with legitimate access to the AP.
DHCP Server (for AP mode only)
DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows administrators to assign
temporary IP addresses to network computers by “leasing” an IP address to a user for a limited amount of
time, instead of assigning permanent IP addresses.
The AWK-3131A can act as a simplified DHCP server and easily assign IP addresses to your DHCP clients by
responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will
also be sent to the client.
You can also assign a static IP address to a specific client by entering its MAC address. The AWK-3131A
provides a Static DHCP mapping list with up to 16 entities. Be reminded to check the Active check box for
each entity to activate the setting.
You can check the IP assignment status under Status  DHCP Client List.

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 and netmask
255.255.255.255” refers to the sole IP address 192.168.1.1. “IP address 192.168.1.1 and netmask
255.255.255.0” refers to the range of IP addresses from 192.168.1.1 to 192.168.255. Remember to check

RSTP Settings (for Master or Slave mode only)
AWK-3131A supports IEEE802.1D Spanning Tree Protocol and IEEE802.1w Rapid STP standards. In addition
to eliminating unexpected path looping, STP/RSTP can provide a backup path recovery if a wired/ wireless
path fails accidentally. The reliability and availability can increase because this fail-over function.
AWK-3131A’s STP/RSTP feature is disabled by default. To be completely effective, you must enable
RSTP/STP on every AWK-3131A connected to your network. If AWK-3131A plays a Slave role, which is
connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not necessary to
enable STP/RSTP. The reason is that it will cause unnecessary negotiation. AWK-3131As support STP/RSTP
in Master or Slave mode only.
The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed
explanation of each parameter is given below the figure.

AP port
We recommend you set an edge port for the port, which is connected to a non-STP/RSTP sub-network or
an end device (PLC, RTU, etc.) as opposed to network equipment. This can prevent unnecessary waiting
and negotiation of STP/RSTP protocol, and accelerate system initialization. When an edge port receives
BPDUs, it can still function as an STP/RSTP port and start negotiation.
Setting an edge port is different from disabling STP/RSTP on a port. If you disable STP/RSTP, a port will
not deal with STP/RSTP BPDUs at all.
Port Status
Port Status indicates the current Spanning Tree status of this port. Use Forwarding for normal
transmission, or Blocking to block transmission.

Link Fault Pass-Through (for Client/Slave mode only)
This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once
Ethernet link is recovered, AWK will try to connect to AP.
If wireless is disconnected, AWK restarts auto-negotiation on Ethernet port but always stays in the link
failure state. Once the wireless connection is recovered, AWK 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.

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-3131A supports different approaches to warn engineers
automatically, such as SNMP trap, e-mail, and relay output. It also supports two digital inputs to
integrate sensors into your system to automate alarms by email and relay output.
System Log
System Log Event Types
Detail information for grouped events is shown in the following table. You can check the box for Enable log to

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.

Save Configuration
The following figure shows how the AWK-3131A stores the setting changes into volatile and non-volatile
memory. All data stored in volatile memory will disappear when the AWK-3131A is shutdown or rebooted
unless they are y. Because the AWK-3131A starts up and initializes with the settings stored in flash
memory, all new changes must be saved to flash memory before restarting the AWK-3131A.
This also means the new changes will not work unless you run either the Save Configuration function or
the Restart function.
After you click on Save Configuration in the left menu box, the following screen will appear. Click Save if
you wish to update the configuration settings in the flash memory at this time. Alternatively, you may

Configuring AWK Search Utility
The Broadcast Search function is used to locate all AWK-3131A APs that are connected to the same LAN as
your computer. After locating an AWK-3131A, you will be able to change its IP address. Since the Broadcast
Search function searches by TCP packet and not IP address, it doesn’t matter if the AWK-3131A is
configured as an AP or Client. In either case, APs and Clients connected to the LAN will be located,
regardless of whether or not they are part of the same subnet as the host.
1. Start the AWK Search Utility program. When the Login page appears, select the “Search AWK only”
option to search for AWKs and to view each AWK’s configuration. Select the “AWK management” option

Other Console Considerations
This chapter explains how to access the AWK-3131A for the first time. In addition to HTTP access, there are
four ways to access AWK-3131A: 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-3131A to a PC’s
COM port, can be used if you do not know the AWK-3131A’s IP address. The other consoles can be used to
access the AWK-3131A over an Ethernet LAN, or over the Internet.

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-3131A
to a PC’s COM port, can be used if you do not know the AWK-3131A’s IP address. It is also convenient to
use serial console configurations when you cannot access the AWK-3131A 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-3131A 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-3131A’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.
3. 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.

4. 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).
5. The AWK-3131A’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-3131A and manage the console over a network. To
access the AWK-3131A’s functions over the network from a PC host that is connected to the same LAN as
the AWK-3131A, you need to make sure that the PC host and the AWK-3131A are on the same logical
subnet. To do this, check your PC host’s IP address and subnet mask.
NOTE
The AWK-3131A’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.

AirWorks AWK-3131A
Other Console Considerations
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-3131A’s IP address
from the Windows Run window (you may also issue the telnet command from the MS-DOS prompt).
2. When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the
AWK-3131A’s IP address, specifying 22 for the SSH connection port.
3. 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-3131A supports HTTPS/SSL encryption for all HTTP traffic. Perform
the following steps to access the AWK-3131A’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.
2. Warning messages will pop out to warn users that the security certificate was issued by a company they
have not chosen to trust.

Beacon
A beacon is a packet broadcast by the AP to keep the network synchronized. A beacon includes the wireless LAN
service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps
(DTIM), and the Traffic Indicator Message (TIM). Beacon Interval indicates the frequency interval of AP.
DTIM
Delivery Traffic Indication Map (DTIM) is contained in beacon frames. It is used to indicate that broadcast
and multicast frames buffered by the AP will be delivered shortly. Lower settings result in more efficient
networking, while preventing your PC from dropping into power-saving sleep mode. Higher settings allow
your PC to enter sleep mode, thus saving power.
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.
STP and RSTP
The STP/RSTP Concept
Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide
protection from loops. Networks that have a complicated architecture are prone to broadcast storms caused
by unintended loops in the network. The STP protocol is part of the IEEE802.1D standard, 1998 Edition
bridge specification.
Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by
IEEE802.1w-2001 standard. RSTP provides the following benefits:

•
The topology of a bridged network will be determined much more quickly compared to STP.
•
RSTP is backward compatible with STP, making it relatively easy to deploy. For example:
 Defaults to sending 802.1D-style BPDUs if packets with this format are received. 
 STP (802.1D) and RSTP (802.1w) can operate on the LAN ports and WLAN ports (AP and WDS1WDS8) of the same AWK-3131A. 
This feature is particularly helpful when the AWK-3131A connects to older equipment, such as legacy switches.

Differences between RSTP and STP
RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm
that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring
bridge. Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to
ensure that all other bridges in the network have had time to react to the change. The main benefit of RSTP
is that the configuration decision is made locally rather than network-wide, allowing RSTP to carry out
automatic configuration and restore a link faster than STP.

Firmware Recovery
When the LEDs of FAULT, Signal Strength and WLAN all light up simultaneously and blink at one-second
interval, it means the system booting has failed. It may result from some wrong operation or uncontrollable
issues, such as an unexpected shutdown during firmware update. The AWK-3131A is designed to help
administrators recover such damage and resume system operation rapidly. You can refer to the following
instructions to recover the firmware:
Connect to the AWK-3131A’s ES-232 console with 115200bps and N-8-1. You will see the following
message shown on the terminal emulator every one second.
Press Ctrl - C and the following message will appear.
Enter 2 to change the network setting. Specify where the AWK-3131A’s firmware file on the TFTP server
and press y to write the settings into flash memory.
AWK-3131A restarts, and the “Press Ctrl-C to enter Firmware Recovery Process…” message will reappear.
Press Ctrl-C to enter the menu and select 1 to start the firmware upgrade process.
