MOXA AirWorks AWK-1100 User’s Manual Getting Started
First-Time Installation and Configuration
Before installing AWK-1100, check to 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. AWK-1100 has a default IP address that you must use when connecting to AWK-1100 for
the first time.
NOTE
NOTE
For testing requirements, if you only have one AWK-1100, we strongly suggest that you prepare
a notebook computer or PC with a wireless LAN adapter installed. After finishing the installation
and configuration, you should test AWK-1100 to make sure the wireless transmission is working
normally.
Step 1: Select the Power Source
AWK-1100 can be powered by a DC power input, or by PoE (Power over Ethernet). AWK-1100
will use the power source that you choose.
The PoE capability of the bridge is PowerDsine-compatible. Please visit PowerDsine’s website
for more information (
Step 2: Connect AWK-1100 to a notebook or PC
Since AWK-1100 supports MID/MID-X auto-sensing, you can use either a straight-through cable
or cross-over cable to connect AWK-1100 to the notebook, if the LAN LED on AWK-1100’s front
panel lights up, it means the connection is established.
Step 3: Set up the computer’s IP address
In a Windows environment, the computer’s IP address can be changed in the TCP/IP settings
window. Select an IP address on the same subnet as the AWK-1100. Since AWK-1100’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.
Step 4: Use the web-based manager to configure AWK-1100
Open your computer’s web browser and then type http://192.168.127.253 in the address box 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 OK:
http://www.powerdsine.com).
Default user name & password
User name: admin
Password: root
192.168.127.253
2-2
MOXA AirWorks AWK-1100 User’s Manual Getting Started
NOTE
For security reasons, we strongly recommended changing the password. To do so, open the
Network Manager homepage, click on General Æ Password, and then follow the onscreen
instructions.
Step 5: Select the Operational Mode for AWK-1100
By default, AWK-1100’s operation mode is set to AP/Bridge. If you want to change the setting,
click on General Æ Operational Mode, as shown in the following figure, select an operation
mode, and then click on Save to activate the change.
Go to the General, Operational Mode section, select an operational mode and then click Save at
the bottom of this page. This will take you back to the starting page.
NOTE
The AP supports 2 operational modes:
y AP/Bridge.
This mode provides both Access Point and Static LAN-to-LAN Bridging functionality.
The static LAN-to-LAN bridging function is supported through WDS (Wireless Distribution
System).
y AP Client.
This mode is for Dynamic LAN-to-LAN Bridging. The AP Client automatically establishes
bridge links with APs from any vendors.
In either mode, the AWK-1100 forwards packets between its Ethernet interface and wireless
interface for wired hosts on the Ethernet side and wireless host(s) on the wireless side.
Detailed information about configuring AWK-1100’s Operation Mode is given in Chapter 3.
2-3
MOXA AirWorks AWK-1100 User’s Manual Getting Started
Step 6: Configure AWK-1100’s IEEE 802.11 settings
Go to the IEEE 802.11 Communication section to configure IEEE 802.11g-related communication
settings, including Regulatory domain, Channel number, and Network name (SSID).
The number of available RF channels depends on local regulations; therefore, you will need to
choose an appropriate regulatory domain to comply with local regulations. The SSID of a wireless
client computer and the SSID of the AWK-1100 must be identical for them to be able to
communicate with each other.
When you are finished, click on Save at the bottom of the page. This will return you to the home
page.
Step 7: Review and Apply Settings
On the home page, you can review all of the settings you have made. Changes are highlighted in
red. If the changes are okay, click on Restart to restart the AWK-1100 for the new settings to take
effect.
2-4
MOXA AirWorks AWK-1100 User’s Manual Getting Started
NOTE
About 10 seconds are needed for the AP to complete its restart process.
Deploying the Access Point (AP)
After the settings have been configured, deploy the AP to the field application environment.
Connect the AP to an Ethernet LAN through an Ethernet switch or hub.
If you are configuring a pair of the AWK-1100s for AP mode for a dynamic or static bridging
application and external high-gain directional antennas are used, it is difficult to adjust alignments
of the antennas when the pair of devices are far away.
To adjust the alignments of a pair of bridges’ directional antennas:
1. Connect each bridge to a computer via Ethernet
2. Configure the date rate of each bridge to the lowest value, 1 Mbps.
3. Fix the alignment of the antenna on one side.
4. Adjust the alignment of the antenna on the other side by using response time information
obtained by pinging (i.e., running PING.exe) the “fixed-side” computer.
5. Fine-tune the alignment of the antenna until you get a best response time.
6. Increase the data rate of each bridge simultaneously until a maximum workable data rate is
reached. You may not be able to use the highest data rate, 54 Mbps, because of the distance
and the gain of the antennas.

Setting up Client Computers
The TCP/IP and IEEE 802.11g-related settings of wireless client computers must match those of
the Access Point.
Configuring IEEE 802.11g-related Settings
Open Internet Explorer and type AWK-1100’s IP address in the Address field. Press Enter to
establish the connection.
Before the TCP/IP networking system of a wireless client computer can communicate with other
hosts, the underlying wireless link must be established between this wireless computer and an
Access Point.
2-5
MOXA AirWorks AWK-1100 User’s Manual Getting Started
To establish a wireless link to an Access Point:
1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN
NIC.
2. Use the utility to make appropriate Operating Mode, SSID, and WEP settings.
NOTE
NOTE
NOTE
NOTE
A wireless client computer must be in infrastructure mode to associate with an AP.
The SSID of the wireless client computer and the SSID of the AP must be identical. Or, if the
SSID broadcast capability of the AP is enabled (default setting), the SSID of the wireless client
computer could be set to “any.”
Both the wireless client computer and the Access Point must have the same WEP settings for
them to communicate with each other.
For better wireless security, IEEE 802.1X capability of the Access Point must be enabled so that
only authenticated wireless users can access the wireless network.
Configuring TCP/IP-related Settings
Use the Windows Network Control Panel Applet to change the TCP/IP settings of the client
computers so that the IP addresses of the client computers and the IP address of the Access Point
are in the same IP subnetwork.
If a client computer is originally setup with a static IP address, you can either change its IP address
to match the IP address of the Access Point, or select the option
“automatically-obtain-an-IP-address” if there is a DHCP server on the network.
NOTE
For some versions of Windows, the computer needs to be restarted for the new TCP/IP settings to
take effect.
Confirming the Settings of the AP and Client Computers
After you have completed deploying the Access Point and setting up client computers, you must
make sure the settings you have made are correct.
Checking if the IEEE 802.11g-related Settings Work
To check if a wireless client computer can associate with the AWK-1100:
1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN
NIC.
2. Check if the client computer is associated to an AWK-1100. If the check fails, see Appendix
B, “Wireless Settings Problems,” to troubleshoot the problem.
2-6
MOXA AirWorks AWK-1100 User’s Manual Getting Started
Checking if the TCP/IP-related Settings Work
To check if a client computer can assess the Internet:
1. Open a Windows Command Prompt window on the client computer.
2. Type “ping AP”, where AP is the IP address of the Access Point. Replace it with your real IP
address—for example, 192.168.127.253, and then press Enter.
If the AP responds, go to the next step; otherwise see Appendix B, “TCP/IP Settings
Problems” to troubleshoot the problem.
3. Type “ping default_gateway”, where default_gateway is the IP address of the default gateway
of the wireless client computer, and then press Enter. If the gateway responds, go to the next
step; otherwise, see Appendix B, “TCP/IP Settings Problems,” to troubleshoot the problem.
4. Type “ping 1st_dns_server”, where 1st_dns_server is the IP address of the primary DNS
server of the wireless client computer, and then press Enter. If this DNS server responds, go
to the next step; otherwise, see Appendix B, “TCP/IP Settings Problems,” to troubleshoot the
problem.
