Checksum Calculation:
CHK is transmitted as two ASCII characters calculated with the Checksum formulation.
Checksum = 0 – (SUM of all response data before CHK)
Example: Read stable current weight data.
BSI Examples: (CHK is enabled and instrument address is 01)
Command: 01P[CHK][CR][LF]
Checksum
=
0 − (0x30 + 0x31 + 0x50)
=
0 − 0XB1
=
0x4F
=
Char ‘4’ and ‘F’
Response: 01PS+000123.4[CHK][CR][LF]
Checksum
=
0 − (0x30 + 0x31 + 0x50 + 0x53 + 0x2B + 0x30 + 0x30 + 0x30 + 0x31+ 0x32 + 0x33 +
0x2E + 0x34)
=
0 − 0x02B7
=
0x49
=
Char ‘4’ and Char ‘9’
