RGB Video Balun

500002

Quick Installation Guide

Overview

The RGB Video Balun (500002) allows one component video (YPbPr or RGB) signal to
be transmitted via cost-effective unshielded twisted pair (UTP) cables in the commercial
AV environment.

Used in pairs, the RGB Video Balun supports 480i/p, 720p and 1080i/p resolution for
hi-definition (HDTV) video applications.

The product allows four coaxial cables to be replaced by one Category 5E/6 twisted pair
cable allowing standard structured cabling techniques to be used for more efficient
cabling.

Installation

Troubleshooting

One (1) pair of baluns is needed to complete one component (YPbPr/RGB) connection

via Cat 5E/6 twisted pair. To install the baluns, perform the following steps:

1. Identify the pin configuration of the baluns. Three (3) twisted pairs are required.

The pin configuration follows the EIA/TIA 568A/B standard. The RGB Video
Balun is reverse polarity sensitive. Please ensure that wiring is straight-through
(Ring to Ring, Tip to Tip).

2. The RGB Video Balun comes with three (3) 10” (25 cm) color-coded BNC jumper

cables. Connect the jumper cables to the RGB Video Balun. Connect the other end
of the jumper cables to the corresponding BNC connectors on the RGB video
equipment.

3. Plug the second balun into the component video coaxial cable input of the video

screen or receiver at the remote end.

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 component video equipment. Check the image quality and refer to

the troubleshooting table below if the image quality is unsatisfactory. The
following diagrams show some typical applications.

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

Video Symptom Probable Causes Possible Solutions

No continuity in video link
Power off Check power supplies of video equipment.No video

Improper connection and/or
swapped pair

Unusual colors Reversed polarity

Background pattern EMI interference

Smearing Exceeded distance

Weak contrast

Image not stable Defective link or equipment Verify video equipment interface integrity.
Horizontal bars
moving slowly up or
down the screen

Snowy picture Distance is near limit

Exceeded distance

Unusual link attenuation

Possible ground loop

Verify cable continuity between pairs of
baluns.

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.

Isolate ground loop using ground loop
isolators or lift AC ground using GFCI
outlet.
Verify cable grade.
Use higher grade cable if necessary.
Reduce color intensity at monitor.
