cable is inserted.
RJ45 Ethernet port
LED Indicators
The LEDs on the front panel of the AWK-1131A provide a quick and easy means of determining the current
operational status and wireless settings.
The FAULT LED indicates system failures and user-configured events. If the AWK-1131A cannot retrieve the IP
address from a DHCP server, the FAULT LED will blink at one second intervals. The SIGNAL LEDs indicate
signal strength, and only operate in Client mode.

2. Getting Started
This chapter explains how to install Moxa’s AirWorks AWK-1131A for the first time, and quickly set up your
wireless network and test whether the connection is running well. The Function Map discussed in the third
section provides a convenient means of determining which functions you need to use.

Getting Started
2-2
First-time Installation and Configuration
Before installing the AWK-1131A, 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-1131A 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-1131A can be powered by a DC power input. The AWK-1131A will use whichever power source
you choose.
•Step 2: Connect the AWK-1131A to a notebook or PC.
Since the AWK-1131A supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or
crossover cable to connect the AWK-1131A to a computer. The LED indicator on the AWK-1131A’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-1131A. Since the AWK-1131A’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-1131A will be
reset to factory default settings and the IP address will be reset to 192.168.127.253.
•Step 4: Use the web-based manager to configure the AWK-1131A
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:
NOTE Default user name and password:
User Name: admin
Password: root
For security reasons, we strongly recommend changing the default password. To do so, select Maintenance
Password, and then follow the on-screen instructions to change the password.

NOTE After you click Submit to apply changes the web page will refresh (Updated) will appear on the page and a
blinking reminder will be shown on the upper-right corner of the web page:
To activate the changes click Restart and then Save and Restart after you change the settings. About 30
seconds are needed for the AWK-1131A to complete the reboot procedure.
•Step 5: Select the AWK-1131A operation mode.
By default, the AWK-1131A’s operation mode is set to AP. You can change to Client mode in Wireless
Settings Basic Wireless Settings. Detailed information about configuring the AWK-1131A’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-1131A you can run a sample test to make sure the AWK-1131A and wireless
connection are functioning normally. Two testing methods are described below. Use the first method if you are
using only one AWK-1131A device, and use the second method if you are using two or more AWK-1131A units.
How to Test One AWK-1131A
If you are only using one AWK-1131A, you will need a second notebook computer equipped with a WLAN card.
Configure the WLAN card to connect to the AWK-1131A (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-1131A.
After configuring the WLAN card, establish a wireless connection with the AWK-1131A 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.

AirWorks AWK-1131A
Getting Started
4-2
How to Test Two or More AWK-1131A Units
If you have two or more AWK-1131A units, you will need a second notebook computer (Notebook B) equipped
with an Ethernet port. Use the default settings for the first AWK-1131A connected to notebook A and change
the second or third AWK-1131A connected to notebook B to Client mode, and then configure the notebooks and
AWK-1131A 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 this case, recheck the configuration to make
sure the connections are correct.

Web Browser Configuration
Moxa AWK-1131A’s web browser interface provides a convenient way to modify its configuration and access
the built-in monitoring and network administration functions. The recommended web browser is Microsoft®
Internet Explorer 7.0 or 8.0 with JVM (Java Virtual Machine) installed.
NOTE To use the AWK-1131A’s management and monitoring functions from a PC host connected to the same LAN
as the AWK-1131A, you must make sure that the PC host and the AWK-1131A are on the same logical subnet.
The Moxa AWK-1131A’s default IP is 192.168.127.253.
Follow these steps to access the AWK-1131A’s web-based console management interface.
1. Open your web browser (e.g., Internet Explorer) and type the AWK-1131A’s IP address in the address field.
Press Enter to establish the connection.
2. The Web Console Login page will open. Enter the password (default Username = admin; default Password
= root) and then click Login to continue.
3. You may need to wait a few moments for the web page to download to your computer. Note that the Model
name and IP address of your AWK-1131A are both shown in the title bar of the web page. This information
can be used to help you identify multiple AWK-1131A units.
