1)
See the next table for reference of the range for the RSSI level and RSSI threshold.
2)
The device has received a read or write command and is waiting for a transponder.
Range RSSI Note
A RSSI level (transponder) ≥ RSSI threshold The transponder is within the recommended range of
the reading field.
B RSSI threshold (parameterized) The RSSI threshold can be defined individually (Index:
43h, Sub-Index: 03)
C RSSI level (transponder) ≤ RSSI threshold The transponder is within the maximum range of the
reading field.
