FCS Calculation Method

FCS Calculation Method

The FCS (Frame Check Sequence) is the result of taking the XOR for each byte between the header and footer (8 bits) and converting it to 2 characters of ASCII.

The FCS can be attached to output data to improve the reliability of communications. Each time data is received, the host calculates the FCS and checks it against the FCS attached to the sent data so that the send data can be checked for errors.
