3.1. CFG0: Passwords
The parameters of the CFG0 configuration block contain the identification codes to personalize the
Reader for a user to prevent outside access to some features of the Reader. For security reasons data
from this configuration block cannot be read from the host, they are “write-only”. Also the command
4.5.
[0x83] Set Default Configuration
isn’t available for this configuration block.

READER-ID
1
:
Defines the password with which the host logs into the Reader for a read / write access to the
configuration parameter blocks.
Notes:
•
A READER-ID = 0x00000000 disables the password function.
•
A read with the command
4.2. [0x80] Read Configuration
will always get
‘0x00000000’.
•
A changed password becomes valid after a Reader reset.
•
The commands
4.4. [0x82] Save Configuration to EEPROM
and
4.5. [0x83] Set Default
Configuration
doesn’t change the CFG0 register if all configuration blocks are used.
•
The command
4.1. [0xA0] Reader-Login
is used to enable configuration data access.
Config Protection
By means of Config Protection, the access to the configuration parameters stored within the Reader
is
protected by a 32-bit password, the "READER-ID". This means that only after a "Login" with a valid
READER-ID with the command
4.1. [0xA0] Reader-Login
can configuration parameters in the
EEPROM of the Reader may be read and changed in the EEPROM of the Reader.
