Abstract

PURPOSE:To make it possible to easily change the address and also reduce the cost, by cyclically performing the time division transmission of an address signal, a control signal, etc. from the main operation panel to the terminal equipment by two leased lines, and controlling the load provided on the terminal equipment side. CONSTITUTION:The operation switch unit 43 connects the DC input terminal of the diode bridge 13 to two leased lines 2 through the resistor RX. And one of the two leased lines 2 is connected to the input terminal SIG, and the DC output terminal of the bridge 13 is connected to the electric power source terminal VDD of the logical circuit 11 through the logical circuit electric power source part 10. Also, the transistor Tr0 which has been provided as a return signal driver 12 short-circuits between the two leased lines 2 through the resistor RX by turning it ON and OFF. The logical circuit 11 is formed by a microcomputer of 1 chip, it receives a control signal from the main operation panel, which has been input by the input terminal SIG, and discriminates the coincidence of an address data, and the address of the operation switch unit 43, which has been set by the address setting switches 151, 152... of the address setting part 14.
