3. Configuration Parameters (CFG)
The 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 con-
figuration blocks takes a number (CFG 0...CFG n).
Structure of a configuration blocks in Reader configuration memory and Reader EEPROM (CFG):

The parameters are stored in two different configuration memory locations:
•
Reader RAM
•
Backup EEPROM (used for storing parameter after power down)
Multiple configuration memory locations can be addressed by the value of the parameter CFG-ADR
used in chapter
4. Protocols for Reader Configuration
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
Bit:
Function
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 an faulty checksum is found, the
Reader goes into an error status "EE-Init-Mode" and sets the configuration block which is faulty to the
default values.
While the EE-Init-Mode is active, the LED blinks alternately red and green and the Reader answers
external commands with the status "0x10 EEPROM Failure". The "EE-Init-Mode" can be exited now by
a new reset (cold start or
records are correct, the Reader shifts to the configured operation mode.
Notes:
•
Malfunctions may occur if parameters are configured without their described range or if
unspecified parameters have been changed!
•
A firmware update resets the EEPROM to default settings and the Reader goes into the er-
ror status "EE-Init-mode".
