Note
If the ANT bit in TR_DATA (CFG11) is set in Buffer Info Mode:
•
When a transponder is identified by several antennas, only one data set is saved. The valid time is recorded
only for the first identification. If a data set is transferred to the host and the same transponder is identified
by another antenna, however the valid time has not yet expired, no other data set is saved.
If the ANT bit in TR_DATA (CFG11) is set but not in Buffer Info Mode and a transponder is identified by
•
more than one antenna, the data set for each antenna is saved.
