9.5.3.19 STAY QUIET PERSISTENT
Command code = BCh
When receiving the STAY QUIET PERSISTENT command, the label IC enters the
persistent quiet state and will not send back a response.
Remark: The STAY QUIET PERSISTENT command provides the same behavior as the
mandatory STAY QUIET command with the only difference at a reset (power off). The
label IC will turn to the ready state, if the power off time is exceeding the persistent time.
When in PERSISTENT QUIET state:
The label IC will not process any request where the Inventory_flag is set, except
• the AFI_flag is set or
• the QUIET and PERSTENT QUIET flags in the extended mode of the (Fast) Inventory
command are both set.
The label IC will process any
• EAS ALARM request
• addressed or selected request
The label IC will exit the persistent quiet state when:
• reset (power off) exceeding the persistent time,
• receiving a SELECT request. It shall then go to the Selected state.
• receiving a RESET TO READY request. It shall then go to the Ready state.
The STAY QUIET PERSISTENT shall always be executed in addressed mode
(Select_flag is set to 0 and Address_flag is set to 1).
