Slot_marker(SN) command
Command code = x6h
The SRIX4K must be in Inventory state to interpret the Slot_marker(SN) command.
The Slot_marker byte code is divided into two parts:
On receiving the Slot_marker() command, the SRIX4K compares its Chip_slot_number
value with the Slot_number value given in the command code. If they match, the SRIX4K
returns its Chip_ID value. If not, the SRIX4K does not send any response.
The Slot_marker() command, used together with the Pcall16() command, allows the reader
to search for all the Chip_IDs when there are more than one SRIX4K device in Inventory
state present in the reader field range.
