CHAPTER 2: Introduction
2. Introduction
With the Video Mono Audio Balun, you can transmit two pairs of composite
baseband video and mono audio signals across Category 3 or better unshielded
twisted-pair (UTP) cable, which is already wired into most commercial sites. Use
pairs of Baluns to transmit composite video with mono audio: In a normal two-way
(full-duplex) application, the Balun on each end takes a single composite
baseband video signal and a monaural audio signal from 600-ohm RCA type phono
cables, converts the signals, and transmits them over UTP cable to the other Balun,
which converts them back and sends them to their destination. (If your application
needs both sets of signals to travel in the same direction, the Baluns can do this
too.)
Connect the Video Mono Audio Balun to a site’s structured cabling through a
modular wall jack in the work area. Each Balun has four RCA connectors at one
end and an RJ-45 jack at the other end.
The Video Mono Audio Balun is designed for use with CCTV cameras and
monitors, videocassette recorders, camcorders, and other baseband audiovisual
equipment, but is especially useful in two-way videoconferencing applications.
