向伝送装置。The potentials of the first and second transmission lines are switched so that when one is at a high potential, the other goes to a low potential, and when the other is at a high potential, one goes to a low potential, and at the first station is the second transmission line when the second transmission line is at a high potential.
At the second station, when the first transmission line is at a high potential, the first transmission line is made conductive to the second transmission line, so that each signal is transmitted. However, at the first station, when the first transmission line is at a high potential, by detecting that the first transmission line is electrically connected to the second transmission line, Two-wire bidirectional transmission characterized in that each signal is received by detecting that the second transmission line is electrically connected to the first transmission line when the second transmission line has a high potential. Device.
