Header Message Checksum Checksum Byte Protocol Layout Header Message Checksum Checksum Byte The Checksum is calculated using the following sequence: Sum all bytes over the header and the message. Take modulo 256 of the calculated checksum and do a bitwise invert of the checksum. This calculated checksum is sent along with the packet. The receiver executes the same calculation and verifies the calculated checksum with the received checksum. 14.Mar.07 DCNNG Open Interface
