When communication is to be carried out between a central control unit and an appliance that uses a different form of communication from the central control unit, a converting part for converting commands is provided in a communication path (communication device which may be a communication cable) between the central control unit and the appliance. By this means, communication between the central control unit and peripheral appliances is made possible and central control of the peripheral appliances is possible notwithstanding that their respective forms of communication are different. Therefore, the number of appliances that can be connected to the central control unit is increased. Preferably, the converting part can be set to a mode that corresponds to a respective appliance among a plurality of converting modes. An electronic circuit corresponding to the converting part is for example provided in a communication cable connecting the central control unit to an appliance. |
