Antenna is already switched off
•
Antenna is already switched on
•
Mode in SET-ANT command not recognized.
•
More MDSes are in the transmission window than the SLG is capable
of processing simultaneously.
Only 1 MDS can be processed at a time with FB 45.
•
With FB 45 and FC 55: there is more than one tag with the same
•
EPC ID in the antenna field of the reader.
With FC 55: Increase the value in multitag or decrease the number
•
of MDSes in the field.
With FC 55: A read or write command has been sent on a
•
transponder (UID) and there are one or more transponders in the
antenna field, for which the contents of the addresses FF00 – FF03
of the EPC ID do not agree (unambiguity when transponder is
accessed via 8-byte long UID).
Power supply of the MDS in the limit range:
•
Due to short-term power shortage, an MDS loses its
communications status (session), upon which the identical EPC-ID
is sent a second time as soon as the power threshold is exceeded
again.
Increase the reader's radiated power and/or reduce the distance
between antenna and MDS until this effect no longer occurs.
Wrong number of characters in the command message frame.
Running command canceled by RESET (init_run or cancel) or bus
connector removed
Communication with the tag was terminated by init_run.
