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
NOTE
For security reasons, we strongly recommend changing the default password. To
change the password,
select
Maintenance
Password and follow the instructions on the screen.
NOTE
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.

•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.

AWK-3131A-RTG UM Getting Started
2-4
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.
