8. 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:
6.1. Serial Data Format and Protocol
Access to the configuration parameters is granted only after a
mand 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.
8.1. [0x80] Read Configuration
By using the Read Configuration command 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.
