IPC03 password mode
If the password mode in the data carrier is activated, the data range of the data carrier is read
and write-protected and can only be read or written if the R/W head sends the correct
password to the data carrier.
If the password mode in the data carrier is deactivated, every data word on the data carrier can
be read or written.
The default password of the R/W heads and the data carrier is 00000000h. In the R/W head,
the password is stored in the volatile memory and in the data carrier, the password is stored in
the non-volatile memory.
To read or write the "Protection Word" and the "Control Word", you must first enter the
password in the password mode (see the commands SC or EC).
You can also limit access to the data carriers by defining the start and end of a read-protected
and a write-protected range in the Protection Word.
Setting the password
1. Enter the correct password once with the command PS (set password).
2. Activate the password mode with the command PM (set password mode).
Changing the password
To change the password in the R/W head and on the read/write tag, use the command PC.
