Abstract

Disclosed is a bidirectional repeater in a data transmission system in which a supervisor is connected to one end of a bidirectional bus having connected thereto a plurality of communication units and the bidirectional bus is extended through the bidirectional repeater. In the case of data transmission between the communication units or between one of the communication units and the supervisor, the bidirectional repeater relays signals without delay and without any erroneous operation even in the case of impulsive noise getting mixed in the signals and determines the data transmitting direction prior to data transmission.
