    900031_J - Serial communication Field Size Comment CHECKSUM 2 ASCII hex characters Computed checksum of packet The calculated checksum must have its value in ASCII hexadecimal notation. It is calculated by adding the decimal value of all characters in the packet (excluding start, checksum, and terminator), and then dividing the result by 256.
  • Page 40 900031_J - Serial communication Field Size Comment For an error condition with an incoming command, this field returns an error number to the controlling computer. For non-error conditions, this field returns a status byte/word to the controlling computer. See Table: Response code error codes.
