User’s Manual AW2400mTR
Operational summary
The AW2400mR Radio Module allows the user to create a long-range, wireless
Ethernet network with up to 16 subscriber units per access point. The congu-
ration may include any combination of AW2400mR, AW2400xTR, AW2400iTR and
AW2400xTP radios.
Conguring a wireless link with the AW2400mR 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.
AW2400mR radios may be congured by two dierent 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” meth-
od using the DIP switches and LEDs on the module.
The access point (AP) automatically scans for the best of the 29 available radio fre-
quency 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 AW2400mR
subscriber unit. Each SU encrypts Ethernet trac 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
congured and running it behaves like a continuous Ethernet cable.

Evaluation Kit Contents
The AW2400mR-EVAL 2.4 GHz Wireless Ethernet Module Evaluation Kit contains two
each of the following items:
• AW2400mR Wireless Ethernet Modules
• AW2-2400 Omnidirectional Antennas
• AW-P8 Antenna to Radio Connectors
• AW-POE Power Over Ethernet Injectors
• AW-12VPS 12 Volt Power Supplies
Additional quantities of any of these components may be purchased from AvaLAN
Wireless or our distributors.
To power up a radio module, connect the antenna via the pigtail cable provided.
Connect an Ethernet cable to the RJ-45 jack on the module. Power may be sup-
plied to the module using the 12 VDC wall hanger power supply either through the
Ethernet cable using the POE or directly into the P5 jack on the module.
Provide some physical separation between two radio modules — at least ve feet.
If their antennas are in close proximity, the module radio receivers will be over-
loaded, causing degredation in the bit error rate and slower link performance.

Browser Interface Conguration
1. Digital conguration is done by means of the AW2400mR’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
ipnder.exe from the zip archive, placing it on your desktop or in a convenient folder.
http://www.avalanwireless.com/ipnder/ipnder.zip
Note that this utility only runs on MS Windows, not linux or MAC. If you must use a non-
Windows computer for conguration, 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, ipnder.exe and you should see a window similar to this:
The AW2400mR 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 AW2400mR being congured. 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 al-
low you to change it. It is important that the IP address of the AW2400mR 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
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 AW2400mR’s rmware is required
• An Advanced Links section with a dire warning about advanced users only.
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 specied (or “pass-
word” if you kept the default). If the login succeeds, you will see an admin page similar to
this:

AW2400mTR User’s Manual
PAGE 8
Technical support [phone] www.avalanwireless.com
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 Specied 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, brows-
er 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.
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:

“Easy Key” Conguration
In most cases, the browser interface is a better choice for conguring the modules.
But they also can be congured 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 oper-
ate as the access point provides a unique network ID calculated from its MAC ad-
dress and a unique random encryption key programmed into it during manufacture.
If you do congure 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 o (up) on the module(s) that will oper-
ate as subscriber units (SUs).
2. Select matching frequency channels on all modules or select automatic chan-
nel selection by leaving DIP switches 3-8 o.
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 o). 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 success-
ful key exchange.
6. Repeat steps 4 and 5 for any other SU modules to be congured to the same
A P.
7. disconnect the Ethernet cable and cycle power on all modules for the new
keys to take eect. LED behavior should reect 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 o.
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 eect.
To re-key SUs to a new AP, proceed as in the inital setup, making sure to power up
the AP FIRST.

Adherence to the following is required:
IMPORTANT: The AW2400MR OEM RF Modules have been certied by the FCC for use with other products without any further certication (as
per FCC section 2.1091). Changes or modications not expressly approved by AvaLAN could void the user’s authority to operate the equipment.
IMPORTANT: OEMs must test their nal product to comply with unintentional radiators (FCC section 15.107 and 15.109) before declaring compli-
ance of their nal product to Part 15 of the FCC Rules.
IMPORTANT: The AW2400MR OEM RF Modules have been certied for xed base station and mobile applications. If modules will be used for portable
applications, the device must undergo SAR testing.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiving module.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiving module is connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC-Approved Antennas (2.4 GHz)
Fixed Base Station and Mobile Applications
AvaLAN Modules are pre-FCC approved for use in xed base station and mobile applications. When the antenna is mounted at least 20 cm (7.87”)
from nearby persons, the application is considered a mobile application.
Portable Applications and SAR Testing
When the antenna is mounted closer than 20 cm to nearby persons, then the application is considered “portable” and requires an additional test
be performed on the nal product. This test is called the Specic Absorption Rate (SAR) testing and measures the emissions from the module and
how they aect the person.
RF Exposure
(This statement must be included as a CAUTION statement in OEM product manuals.)
WARNING: This equipment is approved only for mobile and base station transmitting devices. Antenna(s) used for this transmitter must be installed
to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna
or transmitter.
Antenna Warning
WARNING: This device has been tested with Reverse Polarity SMA connectors with the antennas listed in Table 1 below. When integrated into
OEM products, xed antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed
in the table below must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). To fulll FCC
Certication requirements:
1. Integrator must ensure required text [Figure 1] is clearly placed on the outside of the nal product.
2. AW2400MR Module may be used only with Approved Antennas that have been tested with this module.
