The RESET button is located on the top panel of the AWK-3121. You can reboot the AWK-3121
or reset it to factory default settings by pressing the RESET button with a pointed object such as

an unfolded paper clip.

y System reboot: Hold the RESET button down for under 5 seconds and then release.
y R eset 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-3121.

Relay (Digital Output)

The AWK-3121 has one relay output, which consists of the 2 terminal block contacts on the top
panel, as shown below. These relay contacts are used to 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-3121 is not powered.

Chapter 2 Getting Started

This chapter explains how to install Moxa’s AirWorks AWK-3121 for the first time, and quickly
set up your wireless network and test whether the connection is running well. With the function
guide, you can find out the functions you need easily.

In this chapter, we cover the following topics:

 First-time Installation and Configuration
 Communication Testing
 Function Guiding Map

AirWorks AWK-3121 User’s Manual Getting Started

First-time Installation and Configuration

Before installing the AWK-3121, make sure that 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-3121 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-3121 can be powered by DC power input or PoE (Power over Ethernet). The
AWK-3121 will use whichever power source you choose.

Step 2: Connect the AWK-3121 to a notebook or PC.

Since the AWK-3121 supports MDI/MDI-X auto-sensing, you can use either a straight-through
cable or crossover cable to connect the AWK-3121 to a computer. If the LED indicator on
AWK-3121’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-3121. Since the AWK-3121’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-3121 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-3121

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:

2-2

AirWorks AWK-3121 User’s Manual Getting Started

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, you can see that the web page is refreshed, and the
string “(Config Setting Success)” and a blinking reminder will be shown on the upper-right

corner of web page, as follow.

To make the changes effective, click Restart and then Save and Restart after you change the

settings. About 30 seconds are needed for the AWK-3121 to complete its restart process.

Step 5: Select the operation mode for the AWK-3121.
By default, the AWK-3121’s operation mode is set to AP. You can change the setting in Wireless

Settings > Basic Wireless Settings if you would like to use the Client mode instead. Detailed

information about configuring the AWK-3121’s operation can be found in Chapter 3.

Step 6: Test communications.

We will describe 2 test methods to make sure the network connection has been established. Please
refer to the following section for more details.

Communication Testing

After installation, you can run a sample test to make sure the AWK-3121 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-3121 device, and use the second method if you are
using two or more AWK-3121s.

Testing Method for one AWK-3121

If you are only using one AWK-3121, you will need a second notebook computer equipped with a
WLAN card. Configure the WLAN card to connect to the AWK-3121 (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-3121.

2-3

AirWorks AWK-3121 User’s Manual Getting Started

After configuring the WLAN card, establish a wireless connection with the AWK-3121 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-3121s

If you have two or more AWK-3121s, you will need a second notebook computer (B) equipped
with an Ethernet port. Use the default settings for the first AWK-3121 connected to notebook A
and change the second or third AWK-3121 connected to notebook B to Client mode. Then,
configure the notebooks and AWK-3121s 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.

Function Guiding Map

The management functions are categorized in a tree and shown in the left field of the web-based
management console. You can efficiently locate the function you need with the following guiding
