SRIX4K commands
9.2
30/50
PCALL16() command
Command Code = 06h - 04h
The SRIX4K must be in INVENTORY state to interpret the PCALL16() command.
On receiving the PCALL16() command, the SRIX4K first generates a new random
CHIP_SLOT_NUMBER value (in the 4 least significant bits of the Chip_ID).
CHIP_SLOT_NUMBER can take on a value between 0 an 15 (1111
until a new PCALL16() or INITIATE() command is issued, or until the SRIX4K is powered off.
The new CHIP_SLOT_NUMBER value is then compared with the value 0000
match, the SRIX4K returns its Chip_ID value. If not, the SRIX4K does not send any
response.
The PCALL16() command, used together with the SLOT_MARKER() 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.
