    摘要: A repeater unit includes an input circuit having an input terminal that can be connected to output of an upstream repeater unit through a signal cable for inputting a video signal from the input terminal; an output circuit having an output terminal that can be connected to input of a downstream repeater unit through a signal cable for outputting a video signal to the output terminal; and a selection circuit that can be connected to a video signal output device for outputting a video signal and outputs the video signal input from the video signal output device to the output circuit. The input circuit and the output circuit have termination resistors matched with each other. When the repeater units are daisy-chained, termination matching is conducted.
