Set Transceiver PWD command
The
Set Transceiver PWD
command sets a password in the read/write head via a Get com-
mand. The password is stored temporarily in the memory of the read/write head. After the
power supply of the read/write head is reset, the password must be set again in the read/write
head. If an incorrect password is sent, this causes a timeout (unknown error, error code
E1FE8100).
The password set in the read/write head must match the tag password. Refer to the chapter
“Setting the password protection for the tag” for the procedure in the application.
