Abstract

PURPOSE:To realize the transmission system of 1:n with a simple constitution, by the constitution that each terminal device sends sequential data to a controller in synchronizing with a start signal from the controller. CONSTITUTION:When a start trigger signal (S) is outputted from a controller 1, the signal (S) is transmitted to a signal line 31 via a photocoupler 41 and to a delay circuit 2 of the No.1 terminal device 11 via a photocoupler 42. Pulses delayed for a prescribed time with a timer 4 and a Schmitt trigger circuit 5 in the circuit 2 are supplied to one input terminal of an AND circuit 3 and the data signal supplied to the other input terminal of the circuit 3 is transmitted to the controller 1 via a photocoupler 5 and a signal line 32. On the other hand, the pulse of the circuit 5 is supplied to the No.2 terminal device 11 via a photocoupler 43 and the line 31. After that, with the same principle, the data from the No.2 terminal device is transmitted to the controller 1 via an AND circuit 3, photocoupler 45 and a signal line 32.
