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 configu
-
ration may include any combination of AW2400mR, AW2400xTR, AW2400iTR and
AW2400xTP radios.
Configuring 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 configured 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” 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 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.
