PURPOSE:To facilitate operation by connecting between a transmitting processing part and a receiving processing part at the time of initial start and starting self-diagnosis by receiving the test command of a test command sending means by a self-diagnosis processing means. CONSTITUTION:At the time to start a self-diagnosis program, the transmitting processing part 1T and the receiving processing part 1R of its own are connected by a folded cable 4. Besides, by activating a circuit for a wrap test corresponding to it, at the time the initial start, the test command 5 of its own test command sending means is received by the self-diagnosis processing means, and the self-diagnosis program is started, and the self-diagnosis is started. Thus, the start of the self-diagnosis can be easily executed without necessitating complicated operation. |
