    CHAPTER 2: Introduction 2. Introduction With pairs of S-Video Baluns, you can transmit a single S-Video signal point-to- point across Category 5 unshielded twisted-pair (UTP) cable, which is already wired into most commercial sites. The balun near the video source takes a single S-Video signal from the source, converts it, and transmits it over UTP cable to the other balun, which outputs it to its destination.

  • Page 9: Installation

    S-VIDEO BALUN 3. Installation To install a pair of S-Video Baluns, follow the steps below. CAUTION! Do not attempt to open the housings of the S-Video Baluns. There are no user-serviceable parts inside. 1. Make sure that the video-destination device is not too far away from the video- source device (refer to the Maximum Distance specification in Chapter 1).
  • Page 10 CHAPTER 3: Installation 6. Connect one end of a UTP cable to each balun’s RJ-45 modular jack, as shown in Figure 3-1. These cables must carry at least two wire pairs; these wires must be on RJ-45 Pins 4 (C/chrominance ring), 5 (C/chrominance tip), 7 (Y/luminance ring), and 8 (Y/luminance tip).

    If at any point the problem goes away, there is probably a defect in the balun you just replaced. 6. If you still cannot diagnose the problem, call Black Box for technical support as described in the next section.
