PURPOSE:To detect a part where a cable connected between cards is inserted erroneously. CONSTITUTION:An output control circuit 11 which sends out a cable designation signal and an inspection signal to the card A on one side connected with the cable, a selection circuit 12 which switches the internal signal of the card A to the inspection signal from the output control circuit 11 by the cable designation signal, an input control circuit 13 which reads the inspection signal inputted to the card B via the cable 20, a processor 14 which decides whether or not correct connection is performed by comparing the content of the inspection signal outputted from the output control circuit 11 with that of the inspection signal inputted to the input control circuit 13, and a result display part 17 which displays the part where the cable Is connected erroneously. Thereby, the erroneous insertion and unconnected part of the cable can be detected. |
