A system and a method for industrial communication, employing an adaptive repeater supporting communication between at least two communicating devices using one of two or more predetermined communication protocols at a time instant, are provided. The adaptive repeater includes a communication direction module and a protocol adapter module operably coupled to one another. The communication direction module detects a direction of communication between the communicating devices using physical layer parameters of the communication protocols, and establishes communication there-between, using a sampling clock. The protocol adapter module adapts the communication direction module to the communication protocol in use, by generating the sampling clock.

A relay device or a connection cable for relaying a video signal from a transmission device to a reception device includes a control unit for detecting whether the received video signal is an AC signal output or a DC signal output, and a current pulling unit for pulling a predetermined current from the received video signal. If the received video signal is an AC signal output, the control unit is configured to control the current pulling unit to pull the predetermined current. If the received video signal is a DC signal output, the control unit is configured to control the current pulling unit to stop the pulling of current, and to transfer the video signal from the transmission device to the reception device.
