V1A2 Video Stereo Audio Balun

Installation Guide

Overview

The V1A2 Video Stereo Audio Balun transmits composite baseband video and

audio signals via unshielded twisted pair (UTP) cable in a Structured Cabling

System. The V1A2 is used in pairs to transmit standard NTSC, SECAM, and PAL

composite video. It converts a composite baseband video signal from 75 ohms coax

to 100 ohms for UTP transmission, as well as 1000 ohm stereo audio to 100 ohms.

The V1A2 is connected to the structured cabling via a modular wall jack in the work

area. It is equipped with a BNC 75 ohm connector and two standard RCA phono

jacks at one end, as well as an RJ45 jack at the other end.

Applications

The V1A2 is designed for use with CCTV cameras and monitors, videocassette

recorders (NTSC, PAL, or SECAM), video-conferencing, and other audio/video

equipment. Applications include: security/surveillance monitoring, video bulletin

boards, financial information services, news services, education, video training,

airport displays, video capture, stock exchange, hotels, and convention centers.

Installation

Caution: Do not attempt to open the Balun housing. There are no user-

serviceable parts inside the V1A2. Opening the unit will void your

warranty.

To install a V1A2 Balun, perform the following steps:

1. Turn off power and disconnect the video equipment by following the

manufacturer’s instructions.

2. Make certain that telecommunications outlets and cross connects to which you

will connect the V1A2 are configured properly and labeled appropriately to

identify the circuit.

Caution: Do not connect the V1A2 to a telecommunication outlet wired to

unrelated equipment. Making such a connection may damage the

equipment and/or Balun. Please ensure all wiring is “straight-

through.”

3. Verify the desired twisted pairs are not being used for other LAN or telephony

equipment.

Caution: Do not mount the Balun over equipment ventilation openings.

Covering the openings may cause the equipment to overheat.

4. V1A2 Baluns operate in pairs.

5. Depending on the equipment being connected, connect the BNC connector of

the V1A2 to the coax connector or cable of the video equipment. The two

audio channels provided may be used if required. Either one or both channels

may be used depending on the application (BNC and phono plug cables must

be obtained separately).

6. Connect one end of a UTP line cord to the RJ45 modular jack of the V1A2.

7. Plug the other end of the line cord into the appropriate video wall outlet or

patch panel.

8. Power up the video and/or audio equipment.

Troubleshooting

If your equipment malfunctions with V1A2 Baluns in place, follow the

troubleshooting procedures below:

1. Perform diagnostics on your video equipment by following the manufacturer’s

instructions.

2. Check all the connections and the structured cabling system. Verify the RJ45

crimp pattern conforms to either EIA/TIA 568A or 568B standards, as shown

below.

3. The maximum operational distances over which the video signals can be

transmitted is dependant on the equipment used. See table 1 for the maximum

recommended operational distances over which the video signals can be

transmitted. Ensure that the maximum recommended operational distances

have not been exceeded.

4. Check that the proper patch cord has been used for the cable type.

5. Replace the V1A2 Balun with another V1A2 Balun that is known to be

working.

6. If you still cannot diagnose the problem, call Intelix for support.
