Overview
The AWK-4121 outdoor wireless Access Point is an ideal solution for industrial applications that are hard to wire,
too expensive to wire, or use mobile equipment that connect to a TCP/IP network.
The AWK-4121 is rated for operation in the temperature range from -40 to 75°C, and its dust-tight and
weatherproof design is IP68-rated. An IP68 rating means the device is completely protected from dust and is
protected against the effects of immersion in water between 15cm and 1m in depth. This means you can set up
a WLAN or extend existing wired networks to outdoor locations and still maintain a reliable connection. The
AWK-4121 has two redundant DC power inputs for increased reliability, can be powered via PoE (discontinued
starting with HW Rev 2.0.0), and is easy to deploy.

button.
Relay (Digital Output)
The AWK-4121 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-4121 is not powered.
The AWK-4121’s relay status is summarized as follows:

AWK-4121 Getting Started
2-2
First-time Installation and Configuration
Before installing the AWK-4121, 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-4121 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-4121 can be powered by DC power input or PoE (discontinued starting with HW Rev 2.0.0). The
AWK-4121 will use whichever power source you choose.
Step 2: Connect the AWK-4121 to a notebook or PC.
Since the AWK-4121 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or
crossover cable to connect the AWK-4121 to a computer. The LED indicator on the AWK-4121’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-4121. Since the AWK-4121’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-
4121 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 AWK-4121
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 your changes, the web page is refreshed (indicated by an “(Updated)”
status
appearing next to the title) and a
blinking reminder to restart the device for the new settings to take effect,
will
be shown on the
upper-right corner of web page, as follows.
To
activate the changes, click Restart and then Save and Restart after you change the settings.
About 30
seconds are required for the
AWK-4121 to complete the restart process.
Step 5: Select the AWK-4121 operation mode.
By default, the AWK-4121’s operation mode is set to AP. You can change the setting to Client mode in Wireless
Settings
→
Basic Wireless Settings. Detailed information about configuring the AWK-4121’s operation can
be found in Chapter 3.
Step 6: Test communications.
In the following sections we will describe two test methods that you can use to verify if a network connection
has been established.
Communication Testing
After installing the AWK-4121 you can run a sample test to make sure that the AWK-4121 and the wireless
connection are functioning normally. Two testing methods are described below. Use the first method if you are
using only one AWK-4121 device, and use the second method if you are using two or more AWK-4121 units.
Testing Method for One AWK-4121
If you are only using one AWK-4121, you will need a second notebook computer equipped with a WLAN card.
Configure the WLAN card to connect to the AWK-4121 (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-4121.
After configuring the WLAN card, establish a wireless connection with the AWK-4121 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-4121 Units
If you have two or more AWK-4121s, you will need a second notebook computer (notebook B) equipped with
an Ethernet port. Use the default settings for the first AWK-4121 connected to notebook A and change the
second or third AWK-4121 connected to notebook B to Client mode. Then, configure the notebooks and
AWK-4121s 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.

3-2
Configuration by Web Browser
Moxa AWK-4121’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
-4121’s
management and monitoring functions from a PC host connected to the same LAN as
the AWK
-4121, you must make sure that the PC host and AWK-
4121 are on the same logical subnet. Similarly,
if the AWK
-4121 is configured for other VLAN settings, you must make
sure your PC host is on the management
VLAN.
The Moxa AWK
-4121’s default IP address is 192.168.127.253.
Follow the steps below to access the AWK-4121’s web-based console management.
1. Open your web browser (e.g.: Internet Explorer) and type the AWK-4121’s IP address in the address field.
Then 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 root 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-4121 are both shown in the title of the web page. This information can
help you identify multiple AWK-4121s.
You can use the menu tree on the left side of the window to open the function pages to access each of
AWK-4121’s functions.
