8.8.16 Command: Set tag password
NOTE
The command is only available for applications with UHF tags and the HF tags TW-
R…-M-B146.
NOTE
The command code for fast 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 head. 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.
The password function is only available in HF applications in single-tag mode. An error message
is output with multitag applications. For troubleshooting set the
HF: multitag mode parameter
to 0 : Multitag mode off .
