Connect the transmitter's BNC male connector directly to the BNC port of the SDI video source. Connect the receiver to the display or other receiving equipment in the same manner. Connect the transmitter and receiver through their ST optical interfaces using a single-mode optical fiber. After connecting the transmitter to the receiver, power on the system to begin normal operation.
