3.3.1.4 DATA DEFINITIONS
Specify which data to read. Up to 3 data definitions can be defined (A, B and C). These data definitions can be
allocated to one or more search definitions.
Please make sure that the total length of the data does not exceed the maximum (depending upon the
operating mode. See chapter 3.3.1.1). The total data length is determined by the data type, data length, constant
data for all allocated data definitions. When the data length for the search definition exceeds the maximum the
data will be truncated.
Allocation of data to search
definition
Allocate the data definition to one or more search definitions.
It is also possible to have more than one data definition allocated to the
same search definition.
Data type Type of transponder data to be read.
□ Unique ID
□ Segment stamp
■
Segment data
Data address Start address of the first byte to read.
Address 0 is the first byte. See also the
'Stamp length' setting in the search definition for prime transponders.
Data length (in bytes) Number of data bytes to read.
UID options UID formatting options:
□ Alignment left or right
□ Include size
□ ISO14443A reverse byte order (0x11223344 -> 0x44332211)
□
LEGIC Prime format (0x11223344 -> 0x11443322)
CRC type CRC calculation across the read data (only for segment data)
■ No CRC calculation
□ CRC calculation with 8 bits
□ CRC calculation with 16 bits
CRC address Address of CRC when reading data.
CRC options (prime only) CRC calculation for LEGIC prime transponders coverage.
□ Stamp
□
WRP/WRC/RD
Constant Data For each data definition optionally 1 or 2 bytes of constant dat
a can be
added. This data can be located before or after the transponder data.
