1.3 Operation
The W900iMTR Radio allows the user to create a long-range, wireless Ethernet network with up to 16
subscriber units per access point. The configuration may include any combination of AW900MTR,
AW900XTR and AW900XTP radios. (Please note that older AvaLAN 900 MHz radios can exist on the
same LAN but cannot be used to form wireless links with the AW900MTR/XTR/XTP units because link
encryption protocols have changed.)
Configuring a wireless link with the AW900MTR requires the establishment of six elements:
 Each radio must know whether it is to be an access point (AP) or subscriber unit (SU).
 Each radio must have an IP address that is unique among all others on the same network.
 The AP must know how many SUs are expecting communication with it.
 The AP and any given SU must agree on which radio frequency channel they are using. This can be
manually set or allowed to change automatically.
 The SU must be assigned a unique subscriber ID to specify which time division slot it will use
when communicating with the AP.
 The AP and any given SU must share a common 128-bit encryption key.
AW900MTR radios may be configured by two different methods. They may be connected to a computer
that will run a web browser, setting parameters via their built-in browser interfaces. They may also be
programmed via the older “easy key” method using the DIP switches and LEDs on the module.
If you wish to use the older method, go to the Old Method section and follow the procedures there.
The access point (AP) automatically scans for the best of the 12 available radio frequency channels,
encrypts Ethernet data received from the network, and transmits it wirelessly to the correct subscriber unit
(SU). The AP is constantly monitoring the radio link and can automatically change the channel if
performance is degraded due to interference. If two AP units are very close to one another, they may
interfere if operating on adjacent frequency channels. Place them at least 10 feet apart or manually select
non-adjacent channels for their operation. Also, the SU should be placed at least 10 feet from the AP to
avoid overloading the radio’s receiver.

Any 10/100 BaseT Ethernet client device (ECD) can be connected to an AW900MTR subscriber unit. Each
SU encrypts Ethernet traffic received from the attached ECD and transmits the data wirelessly to its AP.
Each SU can be plugged directly into an ECD without adding drivers or loading software. Essentially, once
the AP/SU pair is configured and running it behaves like a continuous Ethernet cable.

1.5.5 AWRF10 Antenna Cable
The AWRF10 is a high quality 10 foot RF Extension cable made from LMR400 RF Cable and assembled
with an RPTNC male on one end (Radio) and a FME connector (Antenna) on the other. This extension cable
allows you to locate your radio up to 10 feet from the antenna. LMR400 is a high quality, standards based,
low-loss cable for use with high gain antennas. The AWRF10 has an RPTNC male (jack) and FME
connector (plug) on either end for easy installation with the AW15 or the AW11 antennas. Other size cables
available.
1.5.6 AWXPM
The AWXPM is a pole mount kit that contains all the hardware needed to mount a long range Yagi style
antenna on a pole. An AW15 or AW11 antenna can be mounted directly to the large aluminum plate, which
is secured to a pole with two U-bolts. The kit includes one (1) pole mounting plate, two (2) pole u-bolts for
mounting the plate on up to a 2” pipe, and two (2) antenna u-bolts for mounting an antenna onto the
mountingplate.

1.5.7 Power Supply
The power supply shipped with the unit will supply 8-24VDC. If you supply your own power, make sure
you connect the wires from the power supply to the power connector correctly. Note the markings on the
power jack located on the bottom of the unit. You can also use a POE enabled switch to power the unit
through the Ethernet cable.
Caution: Do not use POE if you have a power supply connected to the power jack.
Figure 5-Power Connector
1.5.8 EthernetConnection
Connect a CAT5 Ethernet cable to the Ethernet jack located on the bottom of the unit. See Figure 5.
1.5.9 Switch Settings
You can now configure a W900iMTR using a web browser. The switches are not needed if you configure
the units with a web browser.

Automatic frequency selection mode (DIP switches - DIP 3·8 OFF for automatic mode)
 The GC-W900-IM is designed to automatically select and continuously optimize the performance
of its radio channel. The radio channel is monitored to ensure it is providing low error rates
necessary for successful data transmission. In the event that the error rate rises, the access point
will autonomously change to a new channel. There are 12 non-overlapping channels.

Manual frequency selection mode
 The operation of the GC-W900-IM can be restricted to a specific channel within the 900 MHz band
by setting DIP switches 1-8 on the access point as shown in Table 1-Channel Selection. The
subscriber unit responds to the access point's choice of channel and its DIP switches have no effect
and do not need to be selected.

1.7 Digital Setup
1. Digital configuration is done by means of the W900iMTR’s built in browser interface. It should be
powered on and connected at least temporarily to a network containing a computer that can run a
conventional web browser.
2. Copy the ipfinder.exe from the CD, placing it on your desktop or in a convenient folder. You can also
download the file from:
http://www.avalanwireless.com/ipfinder/ipfinder.zip
Note that this utility only runs on MS Windows, not linux or MAC. If you must use a non- Windows
computer for configuration, make sure your subnet mask allows your computer to see 192.168.17.17.
Connect to that default IP address with your web browser, continuing the setup procedure with step 6.
3. Run the IP Discovery Utility, ipfinder.exe and you should see a window similar to this:
The AW900MTR should appear in the list at the default IP address of 192.168.17.17. If it does not, click
“Search” to regenerate the list. If it still does not appear, you have a connection issue and need to re-
examine the cabling or you may have a firewall issue on your computer.

1-12
W900iTR User Guide
4. Double click the list item that refers to the AW900MTR being configured. You should see a second
window that is similar to this:
The information on the left is the current status of the radio, while the boxes on the right allow you to
change it. It is important that the IP address of the W900iMTR is in the same subnet as your computer. For
example, if the subnet mask is 255.255.255.0 ( a class C network), the first three number groups of the IP
address must match. Choose your desired parameters and click “Apply.”
5. Make note of the chosen IP address and password, then click “Go to Device Web Page.” This will cause
your default web browser to launch with the device IP address in the browser address bar. Or you may
launch the browser on your own and enter the web page address manually: http://[the IP address you just
set].
