User’s Manual AW900-SPEC
Operational summary
The AW900-SPEC is a tool that allows you to investigate sources of RF interference in
the900MHzbandandtomakebetterdecisionsabouthowtocongureyourAvaLAN
wireless network.
Leveraging the RSSI (Received Signal Strength Indication) capability from the
AvaLAN AW900xTR, this unit inexpensively provides a browser-interfaced RF spec-
trum analysis capability with appropriate frequency range and sensitivity for site
survey applications.
Physical Setup
1. The AW900-SPEC comes with a small omnidirectional antenna. If you wish to test
with a directional antenna, you might want to use one of AvaLAN’s alternatives:
• AW10-900 Outdoor Flat Panel 10 dBi High-gain Directional Antenna
• AW11-900 YAGI 11 dBi High-gain Directional Antenna
• AW15-900 YAGI 15 dBi High-gain Directional Antenna
2. Place the unit in the desired location and connect your antenna of choice.
Connect an Ethernet cable to the RJ45 Jack on the AW900-SPEC. The water-tight
gasket allows the cable connector to pass through it (you may need to trim off anti-
snag ears) and then may be tightened down around the cable to seal it. The cable
should be long enough to reach a point near a 120 VAC outlet.
3. The included power-over-Ethernet injector (POE) provides the means for adding
DC power to unused wires in the cable. Plug the included power supply into an ap-
propriate electrical outlet and into the POE. Connect an Ethernet cable between
your PC and the “DATA IN” port on the POE. Connect the cable from the AW900-SPEC
to the “P + DATA OUT” port.
4. Your PC requires a wired LAN connection and should be capable of running a
standard web browser such as Internet Explorer or Firefox.
5. For convenient portable use, the optional accessory AW-POE-USB provides a way
to power the AW900-SPEC from a USB port on your laptop. This accessory is a spe-
cial cable with both a LAN and USB connector on one end and a LAN with injected
power on the other end. The USB connection is only used for DC power and draws
a maximum of 380 mA.
