Quick Installation Guide

Moxa AirWorks

Fourth Edition, December 2010

Overview

Moxa’s AWK-3121 Access Point/Bridge/AP Client is ideal for applications
that are hard to wire, too expensive to wire, or use mobile equipment that
connects over a TCP/IP network. The AWK-3121 is rated to operate at
temperatures ranging from 0 to 60°C for standard models and -40 to
75°C for extended temperature models, and is rugged enough for any
harsh industrial environment. Installation is easy, with either DIN-Rail
mounting or distribution boxes. The DIN-Rail mounting ability, wide
operating temperature range, and IP30 housing with LED indicators make
the AWK-3121 a convenient yet reliable solution for any industrial
wireless application.

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 a 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 the 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 and subnet mask to 255.255.255.0.

Step

4: Use the web-based manager to configure

AWK-3121

Open your computer’s web browser and then type
http://192.168.127.253 in the address field to access the homepage
of the web-based management. Before the homepage opens, you will
need to enter the user name and password. For first-time configuration,
enter the default user name and password and then click on the Login
button:

User name: admin
Password: root

ATTENTION

For security reasons, we strongly recommend changing the
password. To do so, select Maintenance  Password, and then
follow the on-screen instructions.

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.

NOTE To make the change effective, you must click Save Configuration

to save the change or Restart ( Save and Restart button to apply
all changes.

Step 6: Test communications

We will describe two test methods. Use the first method if you are using
only one AWK-3121, 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 (B) equipped with a WLAN card. Configure the WLAN card to
connect to the AWK-3121 (the default SSID is MOXA) and change the IP
address of notebook B so that it is on the same subnet as the first
notebook (A), which is connected to the AWK-3121.

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 the Enter key. 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

- 3 -

the first AWK-3121 connected to notebook A, and change the second or
third AWK-3121 connected to notebook B to Client mode and 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 key. 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.

DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the AWK-3121 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the AWK-3121, make sure the
stiff metal spring is situated towards the top, as shown in the figures
below.

STEP 1:

Insert the top of the DIN-Rail into

the

slot just below the stiff metal spring.

STEP 2:
The DIN-Rail attachment unit will
snap into place as shown below.
