NOTE:
A READER-ID = 0x00000000 disables the password function. CFG_ACCESS has to be
0x00000000

protected.
A read with the command
8.3. [0x80] Read Configuration
will always get ‘0x00000000’ for
the READER-ID.
To change the READER-ID you must write to the CFG0 immediately after the Login to the
Reader with the command

It is possible to disable the READER-ID with an activation code, if the READER-ID is un-
known. The activation code must be ordered by your supplier or FEIG ELECTRONIC GmbH.
Config Protection
By means of Config Protection, the access to the configuration parameters stored within the Read-
er
is protected by a 32-bit password, the "READER-ID". This means that only after a "Login" with a
valid READER-ID the configuration parameters in the EEPROM of the Reader can be read and
changed in the EEPROM of the Reader.
