User’s Manual AW900-SPEC
Operational summary
The AW900-SPEC is a tool that allows you to investigate sources of RF interference in
the 900 MHz band and to make better decisions about how to configure your AvaLAN
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.
