Crc Calculation Data - SATO CL4NX Programming Reference Manual

CRC calculation data

Following shows a part of CRC calculation process when sending print speed <CS> as an example.
Transmission data is STX <A> <CS>2 <Z> ETX, and this will be "02 1B 41 1B 43 53 32 1B 5A 03"
in HEX. The underlined area is CRC calculation range. Generating polynomial is expressed "1010
0000 0000 0001" as binary numbers. 1B is the first object of calculation and it is expressed "0001
1011" as binary numbers. Initial value of CRC is "0".
