STX: 0x02
ATTR: 0x00
LEN: Barcode data length is expressed in 2 bytes ranging from 0x0000 (0) to 0xFFFF (65535).
AL_TYPE: 0x36
DATA: Raw barcode data.
LRC: Check digit.
LRC calculation algorithm: computation sequence: 0xFF+LEN+AL_TYPE+DATA; computation method is XOR, byte
by byte.
² Enable Data Packing, Format 2: Transmit decoded data with the packet format 2 defined below.
Packet format 2: [STX + ATTR + LEN] + [AL_TYPE] + [Symbology_ID + DATA] + [LRC]
STX: 0x02
ATTR: 0x00

AL_TYPE: 0x3B
Symbology_ID: The ID number of symbology, 1 byte.
DATA: Raw barcode data.
LRC: Check digit.
LRC calculation algorithm: computation sequence: 0xFF+LEN+AL_TYPE+Symbology_ID+DATA; computation
method is XOR, byte by byte.
