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 congu­ration may include any combination of AW2400mTR, AW2400xTR, AW2400iTR and
AW2400xTP radios.

Conguring 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 congured 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 traf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 AW2400mTR-EVAL 2.4 GHz Wireless Ethernet Module Evaluation Kit contains
two each of the following items:

• AW2400mTR 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 sup­plied 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 over­loaded, causing degredation in the bit error rate and slower link performance.
