First-Time Installation and Configuration
Before installing the AWK-3131A-RTG, make sure that all items mentioned in the package checklist are in the
box. You will also need access to a notebook computer or PC equipped with an Ethernet port. The
AWK-3131A-RTG has a default IP address that you must use when connecting to the device for the first time.
• Step 1: Select the power source.
The AWK-3131A-RTG can be powered by a DC power input or PoE (Power over Ethernet).
• Step 2: Connect the AWK-3131A-RTG to a notebook or PC.
Since the AWK-3131A-RTG is provided with the MDI/MDI-X auto-sensing capability, you can use either a
straight-through cable or crossover cable to connect it to a computer. When the connection between the
AWK-3131A-RTG and the computer is established, the LED indicator on the AWK-3131A-RTG’s LAN port
lights up.
• Step 3: Set up the computer’s IP address.
Set an IP address for the computer so that it is on the same subnet as that of the AWK-3131A-RTG. Since
the AWK-3131A-RTG’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0,
set the IP address of the computer in the 192.168.127.xxx IP range and subnet mask to 255.255.255.0.
• Step 4: Use the web-based manager to configure the AWK-3131A-RTG
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 following
default user name and password and click on the Login button:
User Name: admin
Password: moxa
For security reasons, we strongly recommend changing the default password. To change the password, select
Maintenance Password and follow the instructions on the screen.
After you click Submit to apply changes, the web page is refreshed and an (Updated) indicator is displayed
next to the page heading along with a blinking reminder to restart the device.
To activate the changes, click Restart and then click Save and Restart after you change the settings. The
AWK-3131A-RTG will take about 30 seconds to complete the reboot process.

• Step 5: Select the operation mode for the AWK-3131A-RTG.
By default, the operation mode of the AWK-3131A-RTG is set to AP. You can change this setting to Client
mode at Wireless Settings WLAN Basic Wireless Settings. Detailed information about configuring
the AWK-3131A-RTG is available in Chapter 3.
• Step 6: Test the network connection.
In the following sections we describe two methods that you can use to test that a network connection has
been established.
Communication Testing
After installing the AWK-3131A-RTG you can run a sample test to make sure the wireless connection on the
AWK-3131A-RTG is functioning normally. Two testing methods are described below. Use the first method if you
are using only one AWK-3131A-RTG device and the second method if you are using two or more
AWK-3131A-RTG units.
How to Test One AWK-3131A-RTG
If you are only using one AWK-3131A-RTG, you will need one additional notebook computer equipped with a
WLAN card. Configure the WLAN card to connect to the AWK-3131A-RTG (NOTE: the default SSID is MOXA),
and change the IP address of the second notebook (Notebook B) so that it is on the same subnet as the first
notebook (Notebook A), which is connected to the AWK-3131A-RTG.
After configuring the WLAN card, establish a wireless connection with the AWK-3131A-RTG and open a DOS
window on Notebook B. At the prompt, type the following:
ping <IP address of notebook A>
and then press Enter (see the figure below). A “Reply from IP address …” response means the communication
was successful. A “Request timed out.” response means the communication failed. In this case, recheck the
configuration to make sure the connections are correct.

How to Test Two or More AWK-3131A-RTG Units
If you have two or more AWK-3131A-RTG units, you will need a second notebook computer (Notebook B)
equipped with an Ethernet port. Use the default settings for the first AWK-3131A-RTG connected to notebook
A and change the second or third AWK-3131A-RTG connected to notebook B to Client mode, and then configure
the notebooks and AWK-3131A-RTG units properly.
After setting up the testing environment, open a DOS window on notebook B. At the prompt type:
ping <IP address of notebook A>
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 the latter case, recheck the configuration to
make sure the settings are correct.

Wireless Settings
The essential settings for wireless networks are presented in the wireless settings function group. You must
configure these settings correctly before you establish your wireless network. Familiarize yourself with the
following terms before starting the configuration process:
AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data.
Client: When the AWK-3131A-RTG is configured for Client mode, it 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.
Operation Mode
The AWK-3131A-RTG supports five main operation modes—AP, Client, and Client-Router, each of which
plays a distinct role on the wireless network.

Basic Wireless Settings (Multiple SSID)
You can add new SSIDs or edit existing ones in the WLAN Basic Setting Selection panel. You can configure
up to 9 SSIDs for an AWK and configure each SSID differently.
An SSID is a unique identifier that wireless networking devices use to establish and maintain wireless
connectivity. Multiple access points on a network or sub-network can use the same SSIDs. All of the SSIDs that
you configure for an AP are active at the same time. That is, client devices can use any of the SSIDs to associate
with the AP.
To create an SSID for your AWK, click on Add SSID. To edit an existing SSID and assign different configuration
settings to it, click on the Edit button corresponding to the SSID. A configuration panel is displayed as follows:

WLAN Security Settings
The AWK-3131A-RTG 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-3131A-RTG 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 IEEE 802.1X.
The AWK-3131A-RTG can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

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)
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 IEEE 802.11
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-RTG
provides 4 entities of WEP key settings that can be selected to use with Key index.
AWK-3131A-RTG UM
Web Console Configuration

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 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-RTG 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 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.

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 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 WLAN Setup WLAN Certificate Settings to import your WLAN certificate and enable
EAP-TLS on the client end.
AWK-3131A-RTG UM
Web Console Configuration
3-19
You can check the current certificate status in Current Status if it is available.
• Certificate issued to: Shows the certificate user
• Certificate issued by: Shows the certificate issuer
• Certificate expiration date: Indicates when the certificate has expired
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-RTG 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.
AWK-3131A-RTG UM
Web Console Configuration
3-20
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.

(-1 dBm/MHz)
Most countries define a limit for the Equivalent Isotropically Radiated Power (EIRP) for an RF transmitting
system. The EIRP should not exceed the allowed value. EIRP = transmission power + antenna gain (dBi).
Transmission power indicates the maximum value of transmission power which the user plans. However, the
real transmitted power depends on the radio module and some facts, such as country, regulatory limitations
and data rate. Please check the Transmission power in Status > Wireless Status for a real and updated value
of transmission power, which the AWK is currently using.
You can refer to the related glossaries in the reference section for detailed information about the

Virtual LAN IP: This IP should be defined as the gateway IP for onboard devices so that all incoming and
outgoing traffic can be routed properly via this common IP in case of any role changes of the onboard clients.
All AeroLink protected clients within the same subnet need to be configured with the same virtual LAN IP.
Virtual WLAN IP: This IP should be defined as the virtual gateway IP for the wayside router, which can route
traffic to any onboard client regardless of the client’s home WAC. This IP only needs to be configured when
different clients have to backup each other while the clients are registered to different WAC units. For the router
to work properly, all clients and the wayside router will need to be configured to have this routing rule (i.e., to
use this virtual WLAN IP).
How AeroLink Protection Works
In vehicle-to-ground applications, it is essential to minimize system downtime and maximize system
availability of the train-to-ground link to ensure proper communication. Moxa’s AeroLink Protection provides a
reliable wireless network-level redundancy protocol to ensure that there will always be a live
onboard-to-ground link, even when failures occur:
1. Communication Failover: AeroLink Protection members can negotiate with each other to automatically elect
an Active node for data communication. If the Active node is no longer capable of sending data across to its
access point, it will inform other Backup nodes to resume the communication via another path.
2. Frequency-Interference Failover: This concept is similar to “Communication Failover.” If the
communication frequency is interfered with and data can no longer be transmitted over the current active
frequency, the connection is resumed via a backup frequency.
3. Device Failover: After handling communication and frequency failures, in order to provide a wireless
network free of single points of failure, AeroLink Protection also checks the device status. If the Active node
has a power failure, the Backup nodes will automatically resume the wireless communication.
4. Scalable: AeroLink Protection is designed to allow multiple backup paths, making it possible for users to
realize a complete redundant wireless network free from all the above failure types.
5. Fast Recovery: In addition to maintaining a redundant wireless network, providing uninterrupted
communication when a failure occurs is equally important. AeroLink Protection is designed to recover from
a failure in under 300 ms.
When you enable the AeroLink Protection function, management packets will be broadcast every 10 ms so that
the devices can negotiate with each other. If these broadcast packets are overwhelming your network, you can
disable this function

When Turbo Roaming is enabled, Turbo Roaming type, RF type, Dual link option, and Scan channels will
be shown as follows. There are two options available for Turbo Roaming type; 50ms (controller-based)
that only works with the RTG version of the access point and the WAC-1001 and WAC-2004, and 150ms
(client-based) that supports all brands of AP. Dual link reduces the packet-loss rate when roaming between
difference APs; this function only works with a single channel roaming structure. The RF type shows the current
RF type that this client is using. There are three Scan channels available. Note that the Scan channels may
need to be modified when the RF type is changed. (For example, channel 36 is not available in B, G, or B/G
Mix mode.)
If you set Turbo Roaming type to 150ms (client-based), three additional roaming parameters, Roaming
threshold, Roaming difference and AP alive check for 802.11b/g (or b/a) are shown as follows:
Roaming Parameters
Setting
Description
Factory Default
Roaming threshold
When the current RSSI value is lower than the “roaming
threshold,” the client will start the roaming process.

Roaming difference
When the RSSI of a candidate AP is greater than “the current
RSSI value plus the roaming difference,” the client will roam to
this new candidate AP.
7
AP alive check
When “AP alive check” is enabled, the client will actively send
alive-check packets over the wireless network; APs who receive
the packets will respond to indicate that they are currently
available. By doing this, the client can maintain a ready list of
available APs, and then quickly hand over to a new AP once it
loses contact with the AP it is currently connected to.

When 50 ms Turbo Roaming is enabled without using the WAC-1001 or WAC-2004, the connection between the
AP and client will not work.
WLAN Certification Settings (Only For EAP-TLS in Client Mode)
When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise.
The AWK-3131A-RTG can support the PKCS #12, also known as Personal Information Exchange Syntax
Standard, certificate formats that define file formats commonly used to store private keys with accompanying
public key certificates, protected with a password-based symmetric key.
Current Status displays information for the current WLAN certificate, which has been imported into the
AWK-3131A-RTG. Nothing will be shown if a certificate is not available.
Certificate issued to: Shows the certificate user
Certificate issued by: Shows the certificate issuer
Certificate expiration date: Indicates when the certificate has expired
You can import a new WLAN certificate in Import WLAN Certificate by following these steps, in order:
1. Input the corresponding password (or key) in the Certificate private password field and then click
Submit to set the password.
2. The password will be displayed in the Certificate private password field. Click on the Browse button in
Select certificate/key file and select the certificate file.

Advanced Settings
Several advanced functions are available to increase the functionality of your AWK-3131A-RTG 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-RTG UM

AWK-3131A-RTG 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.
AWK-3131A-RTG UM
Web Console Configuration
3-29
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.

DHCP Server
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-RTG 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-RTG
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.

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.

IP Protocol Filter
The AWK-3131A-RTG’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-3131A-RTG 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 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 192.168.1.255. Remember to check the Active check box for each

The AWK-3131A-RTG’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-3131A-RTG 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 than 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.

NAT Settings/Port Forwarding (For Client-Router Mode Only)
Network Address Translation (NAT)—or more specifically, one-to-many NAT, NAPT, or PAT—is supported to
facilitate the Client-Router operation mode. This feature translates the out-going communication from multiple
private IPs to a single external IP (WLAN IP) with randomly assigned port for return traffic.
Port Forwarding is needed to allow external devices to initiate communication. Port Forwarding specifies a
static map between external ports (WAN Port) and internal IP/port combos (LAN IP/LAN Port)
Enabling NAT and Port Forwarding provides the following benefits:
• Uses the NAT function to hide the Internal IP address of a critical network or device to increase the level of
security of industrial network applications.
• Uses the same private IP address for different, but identical, groups of Ethernet devices. For example,
1-to-1 NAT makes it easy to duplicate or extend identical production lines

SNMP Agent
The AWK-3131A-RTG 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-3131A-RTG’s MIB can be found in the software CD and supports reading the attributes via SNMP.

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-RTG supports different approaches to warn engineers
automatically, such as SNMP trap and e-mail. It also supports two digital inputs to integrate sensors into your
system to automate alarms by email.

Traps
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.

The serial console connection method, which requires using a short serial cable to connect the AWK-3131A-RTG to a PC’s
COM port, can be used if you do not know the AWK-3131A-RTG’s IP address. It is also convenient to use USB console
configurations when you cannot access the AWK-3131A-RTG over Ethernet LAN, such as in the case of LAN cable
disconnections or broadcast storming over the LAN.
We recommend using the Moxa PComm (Lite) Terminal Emulator, which is available for download at:
http://www.moxa.com/product/download_pcommlite_info.htm.
Before running PComm Terminal Emulator, use a RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the
AWK-3131A-RTG’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 run the PComm Terminal Emulator from the
PComm (Lite) group.
2. In the Port Manager menu, select Open 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.
ATTENTION
Do not use the RS-232 console manager when the AWK-3131A-RTG 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.

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 wireless client 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 of the same
AWK-3131A-RTG.
This feature is particularly helpful when the AWK-3131A-RTG connects to older equipment, such as legacy
switches.
AWK-3131A-RTG UM
References
A-3
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.

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 Firmware Recovery mode
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-RTG’s RS-232 console with 115200bps and N-8-1. You will see the following
message shown on the terminal emulator every one second.
