Abstract
PURPOSE:To secure the control for the double terminal units in the same return time, by supplying the two-directional signals sent from the master unit to the two terminal units having the reverse polarity connection in order to obtain the return signals of shifted two signals. CONSTITUTION:The half-wave rectification is given to the input signal given from master unit 1 and then read into control signal deciding part 9 and address deciding part 10 in the form of the control and address signals each and via logic control part. When the coincidence is obtained between the address read into part 10 and that read into part 11, the signals are sent to monitor input return part 12 and deciding part 10 each to generate the control output from external output part 13. On the other hand, the return signal is sent to unit 1. And now in case the input signal sent from unit 1 is received in the reverse polarity, the terminal units are connected in reverse polarity to each other to the same address. Thus the return signals can be sent to unit 1 in the shifted timing. As a result, the control is possible for double terminal units 2 in the same return time by connecting two units of terminal 2 of the same address to transmission line 3 and then reversing the polarity to receive the half-wave rectification at half-wave rectifying part 5.
