The AW900R2-EVAL 900 MHz Wireless RS-232 Module Evaluation Kit contains two
each of the following items:
• AW900R2 Wireless Ethernet Modules
• AW2-900 Omnidirectional Antennas
• AW-P8 Antenna to Radio Connectors
• 20” USB to Mini-USB Adapter Cables
• 120VAC to 6 VDC Wall Hanger Power Supplies
Additional quantities of any of these components may be purchased from AvaLAN
Wireless or our distributors.
To power up a radio module, make connections to it as shown in this diagram:
Provide some physical separation between two radio module antennas — at least
ten feet. If their antennas are in close proximity, the module radio receivers will be
overloaded, causing degradation in the bit error rate and slower link performance.
