Abstract:
Multiplex nodes (11, 12) connected via multiplex transmission lines (A, B and C), a voltage setting unit 16, which changes the voltage of the multiplex transmission line C to a specified value, a controller IC 14, which detects a failure in the multiplex transmission lines A and B, a protective circuit 15, which writes specified address data received from the controller IC 14 and key word data and sends a state signal corresponding to these pieces of data to the voltage setting unit 16, and a controller IC 14 which writes these pieces of data in a predetermined area of the protective circuit 15 are provided. The controller IC 14 detects a failure, the voltage setting unit 16 connects the specified multiplex transmission line C to a power supply or ground according to a state signal received from the protective circuit 15, thus changing the states of the multiplex transmission lines A and B.
