信号伝送システム。, 2 A base unit and multiple terminals that are assigned individual addresses and can be individually called from the base unit are connected to each other via a common signal line, and each terminal receives a confirmation signal from the base unit. a transmission/reception control circuit that generates a pulse output when receiving a signal and transmits a data input to a signal line when a strobe signal is input; an input change detection circuit that inputs a strobe signal to the transmission/reception control circuit when the data input power changes; and a transmission/reception control circuit. A signal transmission system comprising an AND circuit which takes the pulse output from the circuit as one input and the data input as the other input, and the output of the AND circuit is connected to the strobe signal input terminal of the transmission/reception control circuit.
