First-Time Installation and Configuration
Before installing the AWK-3131A-M12-RCC, 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-3131A-M12-RCC
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-3131A-M12-RCC can be powered by a DC power input or PoE (Power over Ethernet). The
AWK-3131A-M12-RCC will use whichever power source you choose.
•Step 2: Connect the AWK-3131A-M12-RCC to a notebook or PC.
Since the AWK-3131A-M12-RCC supports MDI/MDI-X auto-sensing, you can use either a straight-through
cable or crossover cable to connect the AWK-3131A-M12-RCC to a computer. The LED indicator on the
AWK-3131A-M12-RCC’s LAN port 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-3131A-M12-RCC. Since the AWK-3131A-M12-RCC’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 Default and click the Submit button, the
AWK-3131A-M12-RCC will be reset to factory default settings and the IP address will be reset to

To activate the changes click Restart and then Save and Restart after you change the settings. About 30
seconds are needed for the AWK-3131A-M12-RCC to complete the reboot procedure.
•Step 5: Select the AWK-3131A-M12-RCC operation mode.
By default, the AWK-3131A-M12-RCC’s operation mode is set to AP. You can change to Client mode in
Wireless Settings Operation Mode. Detailed information about configuring the
AWK-3131A-M12-RCC’s operation can be found in Chapter 3.
•Step 6: Test communications.
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 installing the AWK-3131A-M12-RCC you can run a sample test to make sure the AWK-3131A-M12-RCC
and wireless connection are functioning normally. Two testing methods are described below. Use the first
method if you are using only one AWK-3131A-M12-RCC device, and use the second method if you are using two
or more AWK-3131A-M12-RCC units.
How to Test One AWK-3131A-M12-RCC
If you are only using one AWK-3131A-M12-RCC, you will need a second notebook computer equipped with a
WLAN card. Configure the WLAN card to connect to the AWK-3131A-M12-RCC (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-M12-RCC.
After configuring the WLAN card, establish a wireless connection with the AWK-3131A-M12-RCC and open the
Windows Command Prompt 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.

How to Test Two or More AWK-3131A-M12-RCC Units
If you have two or more AWK-3131A-M12-RCC units, you will need a second notebook computer (Notebook B)
equipped with an Ethernet port. Use the default settings for the first AWK-3131A-M12-RCC connected to
notebook A and change the second or third AWK-3131A-M12-RCC connected to notebook B to Client mode, and
then configure the notebooks and AWK-3131A-M12-RCC units properly.
After setting up the testing environment, open the Windows Command Prompt 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 this case, recheck the configuration to make
sure the connections are correct.
