8.8.28 Command: Set tag password
NOTE
The command is only available for applications with UHF tags and the HF tags with
chip types EM42… and NXP SLIX2.
NOTE
The command code for rapid processing with the loop counter is 0x2102 (hex.) or
8450 (dec.).
The Set tag password command sets a password in the tag. Tag protection is not activated
until the Set tag protection command has also been carried out. When sending the command,
only one tag can be located in the detection range of the read/write device. After the password
is sent, other commands (e.g. Set tag protection) can be sent to the tag. The Set tag password
command prevents a Kill password from being set in the tag.
In HF applications, the password function is available in single-tag mode only. A fault signal is
output with multitag applications. To troubleshoot, set the HF: multitag parameter to 0: multi-
tag mode off. In order to use the password function in HF applications, the password in the tag
and the read/write head must match. The default password is 0000 and must be set first of all in
the read/write head before a new password can be assigned ( [}152]. The command is suppor-
ted for chip type NXP SLIX2 of HF read/write heads with firmware version Vx.98 or higher.

Length UID/EPC The UID or EPC size should be entered in bytes if a particular
tag is to be protected. The UID or EPC must be defined in the
write data (start byte: 0). The function of the UID/EPC length
is dependent on the command used.
0: No entry of a UID/EPC for executing the command. Only
one tag can be located in the detection range of the read/
write head.
> 0: EPC length of the tag to be protected if an EPC is
present in the write data
-1: NEXT mode: A tag is only ever protected if the UID/EPC
differs from the UID/EPC of the tag last read or written to.
