Relay (Digital Output)
The AWK-4131A has one relay output, which consists of the 2 contacts for the 8-pin M12 connector on the
bottom panel, as shown below. These relay contacts forward system failure 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 reason, the relay circuit
is kept open when the AWK-4131A is not powered.
The AWK-4131A’s relay status is summarized as follows:

First-time Installation and Configuration
Before installing the AWK-4131A, make sure all items in the Package Checklist are in the box. In addition, you
will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-4131A 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-4131A can be powered by DC power input or PoE (Power over Ethernet). The AWK-4131A will use
whichever power source you choose.
Step 2: Connect the AWK-4131A to a notebook or PC.
Since the AWK-4131A supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or
crossover cable to connect the AWK-4131A to a computer. If the LED indicator on AWK-4131A’s LAN port lights
up, it means the connection is established.
Step 3: Set up the computer’s IP address.
Set an IP address on the same subnet as the AWK-4131A. Since the AWK-4131A’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.
Step 4: Use the web-based manager to configure AWK-4131A
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:

By default, the AWK-4131A’s operation mode is set to AP. If you would like to use the Client mode, you can
change the setting at Wireless LAN Setup --> WLAN --> Basic WLAN Setup. Detailed information about
configuring the AWK-4131A’s operation can be found in Chapter 3.
Step 6: Test the connection.
In the following sections, we describe two test methods that can be used to ensure that a network connection
has been established.

Communication Testing
After installation, you can run a sample test to make sure the AWK-4131A and wireless connection are
functioning normally. Two testing methods are explained in the following sections. Use the first method if you
are using only one AWK-4131A device, and use the second method if you are using two or more AWK-4131A
units.
Testing Method for one AWK-4131A
If you are only using one AWK-4131A, you will need a second notebook computer equipped with a WLAN card.
Configure the WLAN card to connect to the AWK-4131A (default SSID is MOXA), and change the IP address of
the second notebook B so that it is on the same subnet as the first notebook A, which is connected to the
AWK-4131A.
After configuring the WLAN card, establish a wireless connection with the AWK-4131A and open a DOS window
on notebook B. At the prompt, type
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.

Testing Method for two or more AWK-4131As
If you have two or more AWK-4131As, you will need a second notebook B equipped with an Ethernet port. Use
the default settings for the first AWK-4131A connected to notebook A and change the second or third
AWK-4131A connected to notebook B to Client mode. Then, configure the notebooks and AWK-4131As
properly.

System Time
The AWK-4131A has a time calibration function based on information from an NTP server or user specified Date
and Time information. Functions such as Logs and Notifications can add real-time information to the
message.
The Current local time shows the AWK-4131A’s system time when you open this web page. You can click on
the Set Time button to activate the updated date and time parameters. An “(Updated)” string will appear to
indicate that the change is complete. Local system time will be immediately activated in the system without
running Save and Restart.
AWK-4131A has a built-in real-time clock (RTC). We strongly recommend that users update the

Wireless LAN Setup
The AWK-4131A provides two different sets of wireless operation modes: AP/client modes for
point-to-multipoint communication and master/slave modes for transparent point-to-point communication.
The major differences between these two operation modes are the MAC address translation on the client/slave
radio.
AP/client: The IP-Bridging mechanism is used to overcome limitations of the 802.11 standards. In this case,
the MAC address of the devices connected to the client radio will be replaced with the client’s MAC address.
Under AP/client modes, communication problems might be encountered when you have a MAC authenticated
system or MAC (Layer 2) based communication. In this case, you will need to change the network to use the
master/slave operation mode.
Master/slave: A transparent point-to-point protocol that allows the devices’ MAC addresses to remain
unchanged when the packets get through the slave radio. If you are looking for a worry-free wireless solution
to replace your wired system, use Master/Slave.
Client-router: A variation of standard client mode. WLAN behavior is identical with client mode, but a router
behavior was added to separate the WLAN and LAN subnets. This allows network planners to allocate private
IP addresses behind the client radio. More information on the Static Route, NAT, and Port Forwarding functions
can be found in the Advanced Setup section.
Sniffer: In order to provide an easier way to analyze wireless traffic, the AWK-4131A supports a “Sniffer”
mode to co-work with Wireshark packet sniffer software.

AeroMag
Moxa's AeroMag tool enables fast, automatic, and error-free configuration of basic Wi-Fi settings based on the
current wireless environment and location of the APs. The AWK-4131A can be used as an AeroMag client as well
as an AeroMag AP.
Concept
Moxa’s AeroMag technology takes care of the basic Wi-Fi settings for you, saving you considerable effort when
deploying your wireless networks. AeroMag is a useful tool throughout the Wi-Fi network lifecycle. When you
are configuring network devices, AeroMag sets up your Wi-Fi connections correctly in a single step. During the
installation phase, AeroMag streamlines network operation by analyzing the optimal channel for your current
operating environment. From a maintenance perspective, new APs/clients can join the AeroMag topology
without any additional configuration.
Once you have confirmed the number of APs and their location, using a site-survey tool, and have configured
their device names and IP addresses, connect all the APs to the same network using Layer-2 switches. Next,
activate the AeroMag function on both the APs and clients.
AeroMag decides the optimized RF type, channels, WPA2 password and SSID for you. AeroMag APs will
generate an optimal configuration and assign it to AeroMag Clients. AeroMag Clients search AeroMag APs to
achieve the optimal configuration.
