Abstract

PURPOSE:To make it possible to transmit accurately information to a remote place, by reading the information only when an end signal changes at a reception side by transmitting a data signal and data set end signal both at the same time. CONSTITUTION:Data signal 2 from generator 1 at the transmission side is supplied to transmitter 3 and delay circuit 4 and after the signal is delayed by one data amount by circuit 4, generator 5 is driven, which supplies its output data set end signal 6 to transmitter 3. Transmitter 3 scans periodically the input and then, sends it to circuit 7. At the reception side, data input device 10 reads data from the signal inputted to data change decision device 9 via receiver 8, only when signal 6 changes ''O'' to ''1''. Then, the read signal is transmitted to the reception side in the same way as the transmission from the transmission side, and at the transmission side, signals 19 read by input device 18 is compared 20 with signal 2; when they agree each other, next data are sent out and when not, an error process is carried out.
