Each I-Code 1 and I-Code EPC/UID Transponder responds in a chosen timeslot. Choosing
too much timeslots compared to the number of Transponders in the antenna field causes
that only a small number of Transponders can be selected at one time. On the other hand
are too many timeslots very time consuming. The optimum number of timeslots is about
twice the number of Transponders expected in the antenna field at the same time.

Defines which Transponder will sent to the host.

Note:
If 1 timeslot is set and the CRC on an I-Code EPC is wrong the serial number will be transferred
and the status is set to "[0x02] Data False"

A plausibility check is performed by writing this parameter to the Reader. If an error occurs the Reader an-
swers with STATUS = 0x11.
