Astra User Guide 13
Setup Procedure
The steps required to set up and run the Astra Reader are:
1. Connecting the Optional Antenna to the Reader
2. Powering Up the Reader
3. Connecting Your PC to the Reader
4. Setting Up Your PC's TCP/IP Connection
5. Logging On to the Reader
Connecting the Optional Antenna to the Reader
The Astra Reader supports monostatic performance with one (integrated) antenna or with
two (integrated and external) antennas. The power setting that you configure is applicable
to both antennas. However, due to the additional RF loss in the cable, the performance is
less on the external antenna.
Antenna Requirements
The performance of the Astra is affected by antenna quality. Antennas that provide good
50 ohm match at the operating frequency band perform best. Specified sensitivity
performance is achieved with antennas providing 17 dB return loss or better across the
operating band. Damage to the reader will not occur for any return loss of 1 dB or greater.
W A R N I N G !
Damage may occur if antennas are disconnected during operation or if the
Astra.
W A R N I N G !
The Astra antenna ports may be susceptible to damage from Electrostatic
Discharge (ESD). Equipment failure can result if the antenna or communication
ports are subjected to ESD. Standard ESD precautions should be taken during
installation to avoid static discharge when handling or making connections to
the Astra reader antenna or communication ports. Environmental analysis
should also be performed to ensure static is not building up on and around the
antennas, possibly causing discharges during operation.
