SRIX4K commands
9.6
34/47
Reset_to_inventory() command
Command code = 0Ch
On receiving the Reset_to_inventory() command, all SRIX4K devices in Selected state
revert to Inventory state. The concerned SRIX4K devices are thus resubmitted to the
anticollision sequence. This command is useful when two SRIX4K devices with the same 8-
bit Chip_ID happen to be in Selected state at the same time. Forcing them to go through the
anticollision sequence again allows the reader to generates new Pcall16() commands and
so, to set new random Chip_IDs.
The Reset_to_inventory() command does not generate a response.
All SRIX4K devices that are not in Selected state ignore the Reset_to_inventory()
command.
