摘要： PURPOSE:To execute same data communication with plural data terminal equipments quickly and accurately by adopting the constitution such that lines between plural data terminal equipments are connected simultaneously by a command from a computer. CONSTITUTION:Circuit connection information used for connecting a receiver 75 from a computer 73 and a data transmitter-receiver 52 is received by a circuit connection information reception section 67 via a computer interface section 66 and inputted to a circuit connection section 68. Then a line 77 connecting to a data receiver 75 of a circuit interface section section 56 and a line 53 connecting to the data transmitter-receiver 52 of a data terminal equipment 51 are connected by the connection section 68. Similarly, data transmission buses 78,79 are connected and a data from a computer 73 is received by the data receiver 75 via a data transmission line 74, transferred simultaneously via terminal equipments 51,58,61 via the lines 77,53 and the buses 78,79 and the same data communication is implemented with plural data terminal equipments accurately and quickly.
