Quick Installation Guide

Overview

The Quad Video Balun allows up to four (4) composite video signals to be transmitted via an unshielded twisted pair (UTP) cable in a point-to-point connection. Used in pairs, the Quad Video Balun eliminates up to four (4) coaxial cables, allowing audio-video equipment to be connected via a space-efficient and cost-effective Category 5E/6 twisted pair cable. The Quad Video Balun also works in conjunction with other MuxLab composite video baluns such as the 500000, 500009 and 500021.

Installation

One (1) pair of baluns support four (4) composite video signals or one (1) component video (YPbPr) and one (1) composite video signal via a Cat 5E/6 twisted pair. To install the baluns, perform the following steps:

1. Identify the pin configuration of the baluns. Four (4) twisted pairs are required if all four (4) signals are transmitted. The pin configuration follows the EIA/TIA

568A/B standard. The Quad Video Balun is reverse polarity sensitive. Please ensure that wiring is straight-through (Ring to Ring, Tip to Tip).

2. At the video source end, connect a Quad Video Balun to the video output using the appropriate number of RCA or BNC cables.

3. At the video display end, connect a Quad Video Balun to the video input using the appropriate number of RCA or BNC cables.

4. Complete the connection between the two baluns, using standard Cat 5E/6 twisted pair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensure that there are no split pairs or taps.

5. Power-on the video equipment. Check the image quality and refer to the troubleshooting table below if the image quality is unsatisfactory. The following diagram shows a typical installation.

Troubleshooting

The following table describes some of the symptoms, probable causes and possible solutions in respect to the installation of the Quad Video Balun:

Symptom Probable Cause Possible Solutions

No video

Unusual colors

Background pattern

Smearing

Weak contrast

Image not stable

Horizontal bars moving slowly

Snowy picture

No continuity in video link

Power off

Improper connection and/or swapped pair

Reversed polarity

EMI interference

Exceeded distance

Exceeded distance

Unusual link attenuation

Verify cable continuity between pairs of baluns.

Check power supplies of video equipment.

Check that baluns are connected to correct video inputs and outputs.

Check wiring and ensure straight-through polarity

Identify possible radiating frequency sources

(i.e., wireless LANs, switching power supplies). Try to isolate them from the video connection.

Use shielded twisted pair grounded at both ends.

Verify cable grade.

Use higher grade cable if necessary.

Verify cable grade.

Use higher grade cable if necessary.

Increase contrast on monitor.

Verify cable distance using ohmmeter or cable tester.

Defective link or equipment Verify video equipment interface integrity.

Substantial crosstalk Consecutively turn off other video sources to between multiple video determine which video source is the cause of sources

Distance is near limit interference.

Verify cable grade.

Use higher grade cable if necessary.

Reduce color intensity at monitor.

If you still cannot diagnose the problem, please call MuxLab Customer Technical

Frequently Answers and Questions

What can the MuxLab Quad Video Balun transmit?
It can transmit up to four composite video signals or one component video (YPbPr) and one composite video signal.
What type of cable is required to connect the baluns?
Standard Cat 5E/6 twisted pair cable with RJ45 plugs at both ends.
What is the maximum distance that the Quad Video Balun can transmit video signals?
For composite video, the maximum distance is 2,200 ft. For component video (YPbPr), the maximum distance is 500 ft.
How do you troubleshoot the Quad Video Balun if there is no video?
Verify cable continuity between pairs of baluns and check the power supplies of video equipment.
What should you do if there are unusual colors or a background pattern in the video?
Check that baluns are connected to the correct video inputs and outputs, and verify that the wiring is straight-through (Ring to Ring, Tip to Tip).
