TCP/IP network equipment is required to connect to the Reader. The PervasID testing
server is on IP address 93.93.128.16 and requires open ports in the range 9200-9200.
NTP is also required for the reader internal clock.
Power Requirements
An external universal AC to DC power supply, a suitable +24 VDC power supply is
provided with the Reader. This must be fed by an AC single phase supply of 100-240V.
Antenna Requirements
The RFID DAS 9200 is equipped with eight independent TX/RX antenna ports.
1) PeravsID ceiling tile
A 4 beam ceiling tile antenna may be used with the reader in a configuration
such that 5 tiles are required for a cell, with corner antennas shared between
multiple readers. The antenna has a 7.5dBic gain, and the output power of the
reader must be adjusted to account for cable loss.
2) Other Antennas
Operators must use the recommended antennas by PervasID and further
details can be found on page 20. The transmit power must be adjusted
according to the cable length and antenna gain to ensure 2W ERP limit.
It is the installers responsibility to ensure that the combination of the configured
reader output power, cables losses and antenna gain used do not exceed local
regulations. PervasID provide a spreadsheet tool to help calculate the power settings
of the reader which should be used to achieve the maximum allowed output power
for various antenna and cable combinations.
All eight antenna ports may be used in order to maximise the coverage area. However,
should the operators wish to operate with fewer antennas, then the unused ports
MUST be terminated with a 50 ohms load (terminator) or damage to the unit will
result (50 ohms loads are provided with the unit for this purpose).
