4.5.6 G2ULOCKACC: Clear Access Lock
4.5.7 G2LOCKEPC: Set EPC Lock
4.5.8 G2PLOCKEPC: Set EPC Permalock
4.5.9 G2ULOCKEPC: Clear EPC Lock
G2ULOCKACC
Clears the RESERVED memory bank access password lock bit
None
Clears the lock bit of the RESERVED memory bank access password. Prior to executing the
G2ULOCKACC command, the tag must be in the secured state. A tag whose access password is
null will automatically advance from the open state to the secured state during arbitration; a tag
whose access password is non-zero remains in the open state until the tag has successfully
transitioned to the secured state – this is done through the G2ACC command and the valid respective
passwords. Once the access password has been unlocked, it will be readable by the interrogator in
the open or secured states. The access password may be locked while the tag is in the secured state
through the G2LOCKACC command.
G2LOCKEPC
Sets the EPC memory bank lock bit
None
Performs the lock function on the EPC memory bank. Prior to executing the G2LOCKEPC
command, the tag must be in the secured state. A tag whose access password is null will
automatically advance from the open state to the secured state during arbitration; a tag whose access
password is non-zero remains in the open state until the tag has successfully transitioned to the
secured state – this is done through the G2ACC command and the valid respective passwords. Once
locked, the EPC memory bank will still be readable by the interrogator. The EPC memory bank may
be unlocked while the tag is in the secured state through the G2ULOCKEPC command.
G2PLOCKEPC
Sets the EPC memory bank permalock bit
None
Sets the permalock bit of the EPC memory bank. Once the permalock bit has been asserted, the state
of the EPC memory bank lock bit may no longer be altered, whether a logic 0 or a logic 1.
G2ULOCKEPC
Clears the EPC memory bank lock bit
None
Clears the lock bit of the EPC memory bank. Prior to executing the G2ULOCKEPC command, the
tag must be in the secured state. A tag whose access password is null will automatically advance
from the open state to the secured state during arbitration; a tag whose access password is non-zero
remains in the open state until the tag has successfully transitioned to the secured state – this is done
through the G2ACC command and the valid respective passwords.
