PROBLEM TO BE SOLVED: To automatically switch an address interlocking with the presence of a connection of an AUX switch when an AUX BOX is connected to a central unit. SOLUTION: When an AUX SW connector 25 is inserted into a jack 24, a micro-computer 21 incorporated in the AUX BOX 2 detects the insertion through a SW presence detection terminal 23, and outputs the address of an ACCS mode, and the central unit 1 switches to this address. When the AUX SW connector 25 isn't inserted, the microcomputer 21 outputs the address of the AUX mode, and the central unit 1 sets in this address. |
