<p>PROBLEM TO BE SOLVED: To prevent fraudulent actions without increase in load onto controller of each board.SOLUTION: A communication system performs communication of processing data between a main board 11 comprising a main control circuit 71 and a communication LSI T33 and a sub-side board 12 comprising a sub-control circuit 72 and a communication LSI T34. The communication LSI T33 receives the processing data from the main control circuit 71, adds error correction data to the processing data to change data length, encodes the processing data, and transmits the processing data to the communication LSI T34. The communication LSI T34 decodes the processing data received from the communication LSI T33, adds parity bits to the processing data to change data length, and transmits the processing data to the sub-control circuit 72.</p> |
