Processor
Address 12hex, data comparison counter
Using this parameter you can increase data integrity if the CRC_16 checksum is not used. The
processor reads the data carrier data multiple times within a read operation. The processor
stores and compares the data. Once the data carrier is recognized, the processor releases the
data. From 1 to 10 read repetitions can be set in the “Data comparison counter” field.
1 byte, Address 12hex
MSB 6 5 4 3 2 1 LSB
(not relevant) Value range: 01hex…0Ahex
Bit 0 … 3: Permissible value range 01hex … 0Ahex (decimal 1 … 10)
Default setting: 02hex (decimal: 2)
The decimal value is copied directly to the program. If an input value lies outside the permitted
value range, the default setting of 2 comparisons is used.
