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. This lets you place or move your S-Video equipment anywhere you have a modular wall outlet. The S-Video Balun is designed for use with modular equipment and flexible configurations. Compatible devices include S-Video video cameras and monitors, ...

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). If the destination device is beyond the reach of the source balun, the video signal the device receives will be weak or nonexistent. 2. Follow the manufacturer’s instructions for turning off power to the video equipment you will be attaching, and for disconnecting that equipment from AC power an ...

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). Figure 3-1. Attaching UTP cable to the balun. 7. Plug or hardwire the other end of each UTP cable into the appropriate video wall outlet or patch panel. When this is done, a complete cabling circuit should run between the two baluns, as shown in Figure 3-2. Figure 3-2. Two baluns cabled together (not to scale). 8. Reconnect and power up the video equipment. A ...

If at any time your S-Video Balun system does not seem to be working properly, take these steps: 1. Following the manufacturer’s instructions, perform diagnostics on your video equipment. 2. If this doesn’t solve the problem, check all cable connections and the integrity and pinning of your site wiring. Check for reverse polarity; the baluns do not autosense or autocorrect polarity. 3. You might be trying to transmit the video signals across too great a length of cable. The maximum distance over which the baluns can transmit and receive video signals depends on your cable and y ...

4.2 Calling Black Box If you determine that the S-Video Balun is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact Black Box Technical Support at 724-746-5500. Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including: • the nature and duration of the problem; • when the problem occurs; • the components involved in the problem; • any particular application that, when used, appears to create the problem or make it worse; and • the results of any ...
