るデイジタルデータ伝送装置。 The input terminal of the transmitting device and the input terminal of the receiving device are directly connected with one signal line, a DC voltage is applied to the signal line via a resistor on the receiving device side, and the signal is applied on the transmitting device side. The line is grounded through a switching means, and the switching means is opened and closed by a switch opening/closing instruction signal corresponding to the data to be sent from the transmitting device, and the change in the potential of the signal line due to this opening/closing is transmitted to the input of the receiving device. A digital data transmission device that receives data by detecting data from a terminal, and detects a connection state of the signal line by detecting a potential state of the signal line at both input terminals.
