Quick Start Guide
PROGRAMMING:
Step 1. Gather the AvaLAN radios, power supplies, 2x CAT5 cables and a computer with an RJ45
Ethernet interface.
Step 2. Connect the radios one at a time directly to the PC via an Ethernet cable. Set your computer
to an IP address of 192.168.17.1 (refer to page 6 for detailed instructions). Enter the radio’s default
IP address* of 192.168.17.17 into a web browser.
Step 3. Enter the password and click login. The default password is “password”.
Step 4. Click “advanced admin” at the bottom of the web page.
Step 5. Toggle to select the device type - Access Point or Subscriber Unit. An access point (AP) can
communicate with up to 16 Subscriber Units (SU).
• For the AP, enter the maximum number of SUs communicating with the AP.
• For each SU, set the subscriber ID incrementing from one. (Ex. 1, 2, 3, etc.)
Step 6. Enter the “Network Name” and “Encryption Key” using numbers “0-9” and characters “A-F”.
All radios in a single network must have the same “Network Name” and “Encryption Key”.
TESTING:
We recommend connecting and powering up the units on the bench before deploying in the eld.
During bench testing, keep the radios at least 10 feet apart to prevent overload of radio receivers.
Step 1. Power on all the radios with the computer wired directly to the AP.
Step 2. Use the AvaLAN IP nder utility to assign a unique IP address to each radio. (See page x)
Step 3. Open a web browser to view the operation of all the radios. (See page y)
Step 4. Perform PING ood testing to simulate network data and observe overall performance.
INSTALL:
Every installations is dierent, however radio performance is typically best at shorter distances
using directional antennae with unobstructed paths in low noise environments. It can be challenging
to determine the best approach for a unique installation. The radio’s browser interface has a link
performance statistics and a spectrum analyzer display that is helpful for troubleshooting radio
interference noise levels. (See page 9).
Please call AvaLAN Technical Support for assistance as needed.

AW900iTR
User’s Manual
Operational Summary
The AW900iTR Radio allows the user to create a long-range, wireless Ethernet network with up to
16 subscriber units per access point. The conguration may include any combination of AW900iTR,
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 AW900iTR units because link encryption
protocols have changed.)
Conguring a wireless link with the AW900iTR 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 and 32-bit network name.
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 and
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 AW900iTR subscriber unit.
Each SU encrypts Ethernet trac 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 congured and running, it behaves like a transparent Ethernet
cable that encrypts and then passes all trac including VLANs.
Physical Setup
1. Before placing the radio in its nal location, it may be best to perform the digital setup procedure
described in the next section.
2. Connect the AW900iTR’s RP-TNC RF connector to a suitable antenna. A 2 dBI omni-directional
dipole antenna (AW2-900) is included and is suitable for testing and general applications. Application
specic antennas are available if greater range and/or directionality is required. Choose one of our
other antenna models that can be found on our website at www.avalanwireless.com.
3. Power is provided to the unit by means of the 120 VAC to 12 VDC 0.5A wall power supply.

Digital Setup
1. Digital conguration is done by means of the AW900iTR’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. Download the AvaLAN IP Discovery Utility from our website and extract
ipnder.exe from the zip archive, placing it on your desktop or in a convenient folder.
http://www.avalanwireless.com/marketing_resources/downloads/ipnder.zip
Note: This utility only runs on Microsoft Windows, not linux or MAC. If you must use a non-Windows
computer for conguration, make sure your subnet mask allows your computer to see 192.168.17.17.
Connect to that default IP address with your web browser and continue the setup procedure with
step 6.

AvaLAN Radio
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 AW900iTR is in the same subnet as your
computer. For example, if the subnet mask is 255.255.255.0, the rst three number groups of the IP
address must match. Choose the 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]. Note: You are not assigning a password, you’re matching the password that
the unit has built into it.
6. The browser page that loads rst shows the current device information and provides a login in the
upper right. Log in using the password you just specied (or “password” if you kept the default). If
the login succeeds, you will see an admin page similar to this:
The Device Settings section is where the password, channel, DHCP (enable or disable),
network parameters are dened and/or recongured.

7. The admin page has sections similar to the login page showing radio statistics and device
information plus it adds several new sections. The Device Settings section allows setting the network
information and choosing an RF frequency channel. The default is to allow the radio to choose its
own frequency based on minimizing interference. If you set a xed channel, make sure the AP and
all SUs use the same one.
Scroll down in the Admin browser page to see these three additional sections:
1. A graphical spectrum analyzer display that may help you to manually select a radio channel
If you need more information about the interpretation of this diagram
please refer to our Spectrum Analyzer application guide.
2. A section to be used if an update to the AW900iTR’s rmware is required
3. An advanced links section

8. On the Advanced Admin page, set the parameters as follows:
• Choose Device Type: Access Point or Subscriber Unit.
• For Subscriber Units, assign unique ID numbers in numeric order from 1 to 16.
• For an Access Point, enter the number of Subscriber Units that will be communicating with it.
• Choose an 8-digit hex (0-9 and A-F) Network Name that will be common among the AP and its
SUs and enter it. The hyphen is required.
• Choose a 32-digit hex encryption key and enter it. Again, the hyphens are required. This key
must match between the AP and the SU so make a note of it as well.
After entering the parameters, click the “Apply” button to save them to the radio.
9. When all of the radios are keyed and operating, connect them to your network and Ethernet devices as desired and cycle the radio’s power to begin normal operation. Now, browser mamagement
of the SUs can be performed over the wireless network. Note: Avoid plugging actively linked radios
into the same switch because this will corrupt the switch’s routing table and may cause network
problems just as if you had plugged a CAT5 cable directly between two ports of a switch (commonly
called a loop back).

Transmitter to Reciever Placement
If radios are installed either indoors or outdoors at distances closer than recommended, antennas can
overpower each other and cause undesired eects. If testing radios within one or two feet, remove both
antennas. The radios will still be able to signal each other at close distances. This applies to both indoor
and outdoor units.
