Library Security Pedestal 2
52/62 Revision 4.2 July 2008
7 Operation
7.1 Theory of Operation
The RF motherboard in the electronics unit produces radio frequency (RF) electromagnetic
signals that are transmitted via the antennas in each pedestal. Each antenna transmits for a short
period, receives for a short period, and is inactive for the remainder of the time.
When a TAGSYS RFID tag enters the electromagnetic field between two pedestals, some of the
RF energy (AC) is converted to DC energy and used to power the TAGSYS RFID tag’s microchip.
The remainder is used to carry the TAGSYS RFID tag’s EAS signal code back to the electronics
unit via the antennas.
7.2 Starting the System
There is no ON/OFF switch. The system operates when power is applied.
7.3 Normal Operation
No operating procedures are required. The system continues to operate as long as power is
supplied.
7.4 Shutdown
Once the system is set up and running, we recommend that all pedestals remain turned on at all
times.
