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.
