Abstract

PURPOSE:To improve a using efficiency by setting the identification code of an input output device to the identifying line to multi-point-connect a controller and plural input output devices and transmitting and receiving data. CONSTITUTION:With an identifying line 53 to a allocate respective bits of an identification code ID of an input output device 2, a controller 1 and the device 2 are connected, a transmitted part 4 and a discriminating part 5 are provided at the device 2, and a transmitting part 8 and a discriminating part 11 are provided to the controller 1 respectively. When the data are transmitted from the device 2 to the controller 1, after each line 53 is set corresponding to the self-code ID, the data are transmitted from the transmitting part 4 to a second data transmitting line 52, the device 2 is identified from the setting condition of the line 53 by the discriminating part 11 and the data are received. On the other hand, when the data are transmitted from the controller 1 to the device 2, the code ID of an opponent device 2 is set to the line 53, the transmitting data are outputted from the transmitting part 8 to a first transmitting line 51, and the transmitting data are received by the device 2 detected the self-code ID.
