<p>Power supply sockets of a distributing system of interior power supply wiring are provided with a communication distributing terminal, and apparatus (A1-An) are provided with a terminal unit 2 for connection to a communication line CL. A unique address is assigned for the terminal unit 2. A communication line CL is provided with a timing clock supply line TL, a unique address communication line AL, and a local area network (LAN) line LL, thereby connecting the apparatus (A1-An) connected to the power supply socket to the communication line CL. The unique address of the terminal unit 2 connected to the communication line CL is transmitted to the unique address communication line AL, and communication with the terminal unit 2 is controlled through the LAN line LL by the communication control unit 1. The terminal unit 2 transmits its own unique address to the unique address transmission line AL during a predetermined address registration period, when it failed to find its own unique address in unique addresses transmitted from the communication control unit 1. Thereby realizes very easy communication between the apparatus (A1-An). <IMAGE></p> |
