ATTENTION
The
AWK-4131A is NOT a portable mobile device and should be located at least 20 cm away from the human
body.
The
AWK-4131A is NOT designed for the general public. To deploy AWK-4131A
s and establish a wireless network
safely, a well
-trained technician is required for installation.
Functional Design
LED Indicators
The LEDs on the front panel of AWK-4131A allow you to identity the status and wireless settings quickly.
The LED for FAULT indicates the system failure and user-configured events. If the AWK-4131A cannot retrieve
the IP address from a DHCP server, the FAULT LED will blink at an interval of one second.
The following table is a summary for the wireless settings and LED displays. You can check the status of the
AWK-4131A by reading these LEDs. More information about “Basic Wireless Settings” is presented in Chapter
3.

Blinking Data is being transmitted at 10/100 Mbps
Off LAN port’s 10/100 Mbps link is inactive
ATTENTION
When the LEDs for STATE (Green), FAULT, and WLAN all light up simultaneously and blink at one
-second
intervals, it means the system failed to boot. This may be due to impr
oper operation or issues such as an
unexpected shutdown during firmware update. To recover the firmware, refer to “Firmware Recovery” in
Chapter 6.
Beeper
The beeper signals that the system is ready with two short beeps.
Reset Button
The RESET button is located on the bottom panel of the AWK-4131A. You can reboot the AWK-4131A or reset
it to factory default settings by pressing the RESET button with a pointed object such as an unfolded paper clip.
•System reboot: Hold the RESET button down for under 5 seconds and then release.
•Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE LED starts
blinking green. Release the button to reset the AWK-4131A.
STEP 1:
Remove the reset button cover.
STEP 2:
Using a pointed object, pr
ess and hold the reset
button.

AirWorks AWK-4131A Introduction
1-8
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:
Power Status Event Relay
Off – Open
On Yes Open
No Short

AirWorks AWK-4131A Getting Started
2-2
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.
NOTE
After you select
MaintenanceLoad Factory Default and click the Submit button, the AWK-4131A
will be
reset to factory default settings and the IP address will be also reset to
192.168.127.253.
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

NOTE
Clicking
Submit will apply your changes and refresh the web page. The string “(Updated)” and a blinking
reminder will appear on the upper
-right corner of web page as shown below:
To make the changes
effective, click Restart and then Save and Restart
after you change the settings. It will
take about 30 seconds for the AWK
-4131A to restart.
Step 5: Select the operation mode for the AWK-4131A.
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 (NOTE: the 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.
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.

Configuration by Web Browser
Moxa AWK-4131A’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-4131A’s management and monitoring func
tions from a PC host connected to the same LAN as
the
AWK-4131A, you must make sure that the PC host and AWK-4131A are on the same logical subnet.
Similarly, if the
AWK-4131A
is configured for other VLAN settings, you must make sure your PC host is on the
management VLAN.
The Moxa
AWK-4131A’s default IP address is 192.168.127.253.
Follow the steps below to access the AWK-4131A’s web-based console management.
1. Open your web browser (ex. Internet Explorer) and type the AWK-4131A’s IP address in the address field.
Press Enter to establish the connection.
2. The Web Console Login page will open. Enter the password (User Name is set as admin; the default
password is moxa if a new password has not been set.) and then click Login to continue.
You may need to wait a few moments for the web page to download onto your computer. Please note that the
model name and IP address of your AWK-4131A are both shown in the title of the web page. This information
