The RSSI value specifies the signal strength of the signal received by the device.
•
Maximum value: 0x07
•
Minimum value: 0x00
NOTE
The device also reads transponders with a RSSI value of 0x00.
The RRSI threshold specifies the minimal RSSI value that must be achieved so that a
transponder is output. If the RSSI value is below the RSSI threshold, the device does
not output transponder data into the process data.
