Abstract

The clock signal outputted from the clock port(CLK') of the first microcomputer is impressed to photo coupler through the inverter(IV1), resistor(R2) of data output signal(2), and this signal turns on and turns off photo coupler(PC1) at intervals. If the photo coupler(PC2) of data input circuit(3) turns on and turns off periodically through the emitter of the receiving light transistor of photo coupler(PC1), the same clock signal as clock outputted from the first microcomputer(1) is inputted in the second microcomputer(4) through buffer(BF). The data via data port(DATA) passes through data output circuit(2) and data input circuit(3) to be transferred to the second microcomputer(4). The second microcomputer(4) transfers signal to the telephone and beeper of manager.
