In URA v2.3 when a Write to Tag is clicked, whether in the ASCII Editor or Hex
Editor the
entire contents of the User Memory will be written
as shown in the
editor. It WILL NOT only write modified data. This can result in long write
times for large memory tags.
In URA v2.4 this has been fixed so only the edited bytes will be written.
Lock Tag
The Lock Tag operation tab allows the contents of specific tags to be locked and unlocked
and the Access Password of the tag to be written. The tag the operations will be applied
to follows the rules defined in the two Tag Operations
.
Once the tag to operate on has been set the Lock Tag tab supports the following
workflow:
1.
Upon tag selection the Access Password is read (if not read-locked) and
displayed. In order to lock the contents of a tag first the Access Password should
be set to a non-zero value. Contents can be locked with a zero access password
but it will not be secure since no password is required to operate on the contents
of unlock them.
2.
If Access Password Write is clicked the password is written to the tag. From this
point on, for locking to work, the Access Password field in URA must match the
value written to the Access Password section of Reserved Memory (see the
to see the memory structure)
3.
Select the locking operations to be performed and click Apply. The successful,
or failed, locks will be indicated in the Apply Locks section.
– If Access Password is selected to be Read/Write Locked when Apply is
clicked you will first be prompted to save the value being written to a file so it
will be remembered. The saved file will contain the tagʼs EPC ID, full TID and
the password written. Once the file is saved the locks will be attempted.
