7. Configuration Parameters
The
RFC
configuration memory of the Reader is organized in configuration blocks of 16 byte each.
These are divided into 14 byte configuration parameters and a 2 byte CRC16 checksum. Each of
these configuration blocks takes a number (CFG 0...CFG n).

configuration memory of the Reader is organized in configuration blocks of 32 byte each.
These are divided into 30 byte configuration parameters and a 2 byte CRC16 checksum. Each of
these configuration blocks takes a number (CFG 0...CFG n).

The parameters are stored in two different configuration memory locations:
•
Reader RAM
•
Backup EEPROM (used for storing parameter over power down)
Multiple configuration memory locations can be addressed by the value of the parameter CFG-
ADR.
CFG-ADR:
CFGn:
memory-address of the required configuration block
LOC:
specifies the location of the configuration block (RAM / EEPROM)
MODE:
specifies one or all configuration blocks

The EEPROM configuration blocks are protected by a 16 bit CRC-checksum. The examination of
these checksums is executed after each reset of the Reader. If a checksum error is found, the
Reader goes into an error status "EE-Init-Mode" and sets the configuration block which is faulty to
the default-values.
