This product is used to extend a video and stereo audio signal on Cat5 cable to over 2,000 ft. The video input can be Composite Video, or S-Video (both connectors are provided, but only one can be used at any given time).

In a typical installation 2 UBL-CSA units would be required, one as a sender and one as a receiver.

The 100% isolated outputs mean that there is no ground connection between the monitors connected at the output and the video source at the input. This eliminates any ground-loop video or audio noise that can cause hum bars on the video or 60 cycle noise on the audio
