VIDEO BALUN, CCTV VIDEO BALUN, AND CCTV MINI COAX BALUN

2. Introduction

With the Video Balun, CCTV Video Balun, and CCTV Mini Coax Balun, you can transmit composite baseband video 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 standard NTSC, PAL, or SECAM composite video: The balun near the video source takes a single composite baseband video signal from

75-ohm coaxial cable, converts it, and transmits it over UTP cable to the other balun, which puts it back on coax and sends it to its destination.

Connect the Video Balun (IC440A) to a site’s structured cabling through a modular wall jack in the work area. Each Video Balun has a BNC connector at one end and an RJ-45 jack at the other end.

Connect the CCTV Video Balun (IC444A) to a site’s structured cabling by screwing a wire pair into its terminals. Each CCTV Video Balun has a BNC connector at the other end.

Connect the CCTV Mini Coax Balun (IC451A) to a site’s structured cabling by screwing a wire pair into its terminals. Each CCTV Mini Coax Balun has a mini

BNC connector on an 8" (20.3-cm) cable at the other end.

The Video Balun is designed for use with modular equipment and flexible configurations, while the CCTV Video Balun and CCTV Mini Coax Balun are designed for use with fixed equipment and semi-permanent configurations.

Compatible devices include CCTV cameras and monitors, videocassette recorders

(NTSC, PAL, or SECAM), laserdisc and DVD players, videoconferencing hardware, and other baseband audiovisual equipment. Applications include modular security/surveillance monitoring, video bulletin boards, financial information services, news services, education, video training, airport displays, video capture, and informational displays in stock exchanges, hotels, and convention centers.

The baluns must be used in pairs. However, you can install one balun type (such as the IC440A) at one end of the connection and install another balun type (such as the IC451A or IC444A) at the opposite end.

VIDEO BALUN, CCTV VIDEO BALUN, AND CCTV MINI COAX BALUN

3. Installation

To install a pair of Video Baluns, CCTV Video Baluns, or CCTV Mini Coax Baluns, follow these steps:

CAUTION!

It is necessary to open CCTV Video Baluns (IC444A) and CCTV Mini

Coax Baluns (IC451A) in order to install them, but do not attempt to open the housings of Video Baluns (IC440A). There are no userserviceable parts inside.

1. Make sure that the video-destination device is not too far away from the videosource device (refer to the Maximum Distance specification in Chapter 1). If the destination device is beyond the source balun’s reach, 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 and from all other devices.

3. Make certain that the telecommunications outlets and cross-connects to which you will connect the baluns are configured properly and are labeled so that the circuit can be identified.

CAUTION!

Do not connect the Video Balun, CCTV Video Balun, or CCTV Mini Coax

Balun to a telecommunication outlet wired to unrelated equipment.

Making such a connection may damage the equipment and/or the balun.

Make sure that all wiring is pinned straight through.

4. Verify that the twisted-pair circuit you want to use is not already being used for other LAN or telephone equipment.

5. Optional: Each balun comes with VELCRO ® mounting pads. To mount a balun to a surface, first make sure that that surface is free of dust, oil, etc., so the VELCRO will adhere to it. Then peel off the adhesive backing, attach one side of the pads to the balun, and attach the other side to the surface.

CAUTION!

Do not mount the balun over equipment-ventilation openings. Doing so might damage the balun or cause the equipment to overheat.

6. For each balun—depending on what type of equipment you are attaching it to—either plug its BNC male connector directly into the device’s BNC female connector, or plug the balun into a cable that runs to the device (this cable must have a BNC female connector on the balun end).

VIDEO BALUN, CCTV VIDEO BALUN, AND CCTV MINI COAX BALUN

7A. Video Baluns (IC440A) only: 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 one wire pair; these wires must be on RJ-45 Pins 7 (Ring) and 8 (Tip).

7B. CCTV Video Baluns or CCTV Mini Coax Baluns (IC444A or IC451A) only: Look closely at the top of the terminal end of one of your baluns. You will notice two small holes. These are where your wires will enter the balun. Once you find the holes, carefully slide off each balun’s top panel (it slides toward the terminal end). You will see an internal terminal behind each of the external terminal screws. Lay the UTP cable’s twisted-pair wires in the grooves where the holes you found are; then insert one of the wires in one terminal and insert the other wire in the other terminal, as shown in Figure 3-1. (You might have to unscrew the screws slightly to do this. It doesn’t matter which wire goes to which terminal, although we recommend straight-through wiring.)

Tighten the screws and carefully slide the balun’s top panel back on.

4. Troubleshooting

4.1 Things to Try If Problems Occur

If at any time your Video Balun, CCTV Video Balun, or CCTV Mini Coax Balun 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 of your site wiring.

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 your video equipment; refer to the Maximum Distance specification in Chapter 1.

4. Make sure that the patch cord you are running between the balun and your site’s wiring system is the correct cable type and is properly pinned

(see the Cable Required specification in Chapter 1).

5. If possible, replace the baluns involved in the problem with baluns that are known to be working, one at a time. 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.
