Abstract

PURPOSE:To remove the constraint of the transmission control procedure, by transmitting a data pattern of 2 characters as a control signal continuously two times or more, in the data communication data system for receiving a data between the devices through the circuit. CONSTITUTION:When a control signal input 7 is turned on in the transmission side, a data input 6 from the transmission device of the transmission side is suppressed by the data circuit 7 and the lamp circuit 18, and a data pattern of 2 characters of the pattern setting circuit 15 is sent out to the circuit 5. When the shift register 19 has input the data of 2 characters from the circuit 5 in the device 3 of the receiving side, it is compared with the contents of the pattern setting circuit 20, and a control signal 8 is output from the comparator 21 while coincidence is taken continuously two times or more.
