Each of the serial interfaces includes a connection terminal connected to the transmission medium, an input terminal and an output terminal both connected to the associated control unit. Each of the serial interfaces inputs serial data from the associated control unit via its input terminal and outputs the inputted data to the transmission medium via its connection terminal. Each of the serial interfaces inputs serial data from the transmission medium via its connection terminal and outputs the inputted data to the associated control unit via its output terminal.
