Data Packing Formats
Format 1: [STX + ATTR + LEN] + [A DATA] + [LRC]
STX
:
0x02
»
ATTR
:
0x00
»
LEN
:
Barcode message length is expressed by 2 bytes, ranging from 0x0000 (0) to 0xFFFF (65535).
»
AL_TYPE
:
0x36
»
DATA
:
Barcode message
»
LRC
:
Parity byte
»
LRC calculation algorithm:
Computation sequence: 0xFF+LEN+DATA; computation method is XOR, byte by byte.
