User’s Manual AW2400mTR
Operational summary
The AW2400mTR Radio Module 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 AW2400mTR, AW2400xTR, AW2400iTR and
AW2400xTP radios.
Conguring a wireless link with the AW2400mTR 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.
AW2400mTR radios may be congured by two different methods. They may be con-
nected to a computer that will run a web browser, setting parameters via their
built-in browser interfaces. They may also be programmed via the “easy key” method using the DIP switches and LEDs on the module.
The access point (AP) automatically scans for the best of the 29 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 AW2400mTR
subscriber unit. Each SU encrypts Ethernet trafc 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 continuous Ethernet cable.

Browser Interface Conguration
1. Digital conguration is done by means of the AW2400mTR’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/ipnder/ipnder.zip
Note that this utility only runs on MS 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, continuing the
setup procedure with step 6.
3. Run the IP Discovery Utility, ipnder.exe and you should see a window similar to this:
The AW2400mTR 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 rewall issue on your computer.
4. Double click the list item that refers to the AW2400mTR being congured. 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 AW2400mTR is in the same subnet as your computer. For example, if the subnet mask is 255.255.255.0 ( a class C network),
the rst three number groups of the IP address must match. Choose your desired parameters
and click “Apply.”

User’s Manual AW2400mTR
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].
6. The browser page that loads rst shows the current device information and QoS statistics
and provides a login at the upper right. Log in using the password you just specied (or “pass-
word” if you kept the default). If the login succeeds, you will see an admin page similar to
this:
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. References to DIPs on this and the next web
page refer to the DIP switches on the module that are used in the “easy key” method of con-
guration and may be ignored when using the browser method.
If you scroll down in the Admin browser page, you will come to three more sections:
• A graphical spectrum analyzer display that may help you to select radio channels that
avoid interference
• A section to be used if an update to the AW2400mTR’s rmware is required
• An Advanced Links section with a dire warning about advanced users only.
Technical support (650) 384-0000 www.avalanwireless.com
PAGE 7
AW2400mTR User’s Manual
Despite the warning, you will need to click the “Advanced Admin” button in order to set the
device type, ID and encryption key. You should then see a page similar to this:
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 63.
• For an Access Point, enter the number of Subscriber Units that will be communicating
with it.
• Click the box labeled “Enable User Specied Keys.”
• 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 module.
9. When all of the radios are keyed and operating, connect them to your network and Ethernet
devices as desired and cycle the radio module’s power to begin normal operation. Now, browser management of the SUs can be performed over the wireless network. Note: avoid plugging
actively linked radios into the same switch because this will corrupt its routing table and may
cause network problems just as if you had plugged a CAT5 cable directly between two ports
of a switch.

“Easy Key” Conguration
In most cases, the browser interface is a better choice for conguring the modules.
But they also can be congured as a point-to-point bridge or a point-to-multipoint
group using the DIP switches. When this method is used, the module that will operate as the access point provides a unique network ID calculated from its MAC address and a unique random encryption key programmed into it during manufacture.
If you do congure a set of modules this way, be aware that they will all have the
factory default IP address of 192.168.1.17. If you later need access to a module via
the browser interface, use the IP Finder utility, select the individual unit and give
it a unique IP address.
Initial Setup:
1. Select the module that will operate as the access point (AP) and set its DIP
switch 1 on (down). Set DIP switch 1 off (up) on the module(s) that will operate as subscriber units (SUs).
2. Select matching frequency channels on all modules or select automatic channel selection by leaving DIP switches 3-8 off.
3. Power up the AP module. Its link quality LEDs will begin blinking sequentially,
showing that the module is hunting for an SU to exchange keys with.
4. Power up an SU module (its DIP switch 1 is off). This module’s link quality
LEDs will also begin blinking sequentially showing that it is hunting for an AP
to supply a network key.
5. Connect an Ethernet cable from the AP module to the SU module and the two
modules will automatically exchange keys. (Do not connect through a switch
or hub, but cable directly with a regular patch or crossover cable.)
• On the AP module, the link quality LEDs will still blink sequentially in key
exchange mode and the TX LED will light showing successful key exchange
• On the SU module, the link quality LEDs will no longer blink sequentially,
but one of the green link quality LEDs will slowly blink to indicate successful key exchange.
6. Repeat steps 4 and 5 for any other SU modules to be congured to the same
A P.
7. disconnect the Ethernet cable and cycle power on all modules for the new
keys to take effect. LED behavior should reect normal RF operation once the
units are deployed.

User’s Manual AW2400mTR
To add a new SU to the AP, disconnect the AP from the network and power off.
Connect an Ethernet cable between the SU and AP. Power up the SU FIRST and then
the AP. The SU will receive the key. Disconnect the Ethernet cable and cycle power
on the SU to cause the new keys to take effect.
To re-key SUs to a new AP, proceed as in the inital setup, making sure to power up
the AP FIRST.
