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:

–b3 to b0: 4-bit command code

with fixed value 6.

–b7 to b4: 4 bits known as the SLOT_NUMBER (SN). They assume a value

between 1 and 15. The value 0 is reserved by the PCALL16() command.

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.
