Quick Setup Guide:
Plug the RCA connectors of the transmit Balun into the Video and Audio outputs of the source component you wish to transmit. Plug the Video and Audio connectors from the receive Balun into your desired input component. Insert the CAT5 cable into both ends of the Baluns. You may use standard EIA 568A/B termination.
