5. Protocols for Reader Configuration
The Reader configuration protocols allow the Reader to be adapted to the conditions found in indi-
vidual applications. For details about the Protocol Frame see:
Frames.
Access to the configuration parameters is gained only after a 6.10. [0xA0] Reader-Login command
with the correct READER-ID.
In order to avoid unauthorized data access, the Reader is equipped with the following protection
mechanism:
Config-Protection:
Access locking for the configuration parameters stored in the EEPROM of the Reader.
5.1. [0x80] Read Configuration
By using the Read Configuration the actual configuration of the Reader can be detected. In order
to do this, the configuration is read in blocks of 14 bytes each and addressed by CFGn in the byte
CFG-ADR.

CFG-REC:
14 bytes configuration block read from address CFGn in CFG-ADR.
Note:
A read configuration from EEPROM with reserved configuration blocks will cause an 0x15
Read Protect error code.
