Communications
Check code (CS)
It is lower than 1 byte in total of all bytes from frame start symbol to data field.
Example: If the transmission command is '68 01 00 00 00 00 00 68 11 04 33 33 34 33 CS 16',
Check code (CS) is as below.
68 + 01 + 00 + 00 + 00 + 00 + 00 + 68 + 11 + 04 + 33 + 33 + 34 + 33 = 1B3
CS = B3 (CS is lower than 1 byte.)
End symbol (16H)
16H is at the end of the frame.
