Component Video / Digital Audio Balun

500050, 500051

Quick Installation Guide

Overview

The Component Video/Digital Audio Balun (500050, 500051) allows one component
video (YPbPr or RGB) signal and one Digital Audio signal to be transmitted via a cost­effective unshielded twisted pair (UTP) cable.

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

The product allows four coaxial cables to be replaced by one Category 5E/6 twisted pair
cable, enabling 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 for

video and one (1) twisted pair is required for optional digital audio. The pin
configuration follows the EIA/TIA 568A/B standard. The Component
Video/Digital Audio Balun is reverse polarity sensitive. Please ensure that wiring
is straight-through (Ring to Ring, Tip to Tip).

2. Plug one (1) balun into the component video coaxial cable output of the video

source according to the color code of the RCA cable leads.

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. If Digital Audio is to be connected (optional), connect an RCA lead between the

balun and the digital audio equipment at both ends.

6. 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 diagram shows a typical installation.

The following tables describe some of the symptoms, probable causes and possible
solutions in respect to the installation of the Component Video/Digital Audio Balun:

Video Symptom Probable Cause 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

Snowy picture Distance is near limit

Audio Symptom Probable Cause Possible Solutions

No audio

Missing channels

Noise, static

Exceeded distance

Unusual link attenuation

Substantial crosstalk
between multiple video
sources

Distance exceeded Verify cable length between the two baluns.
Split pair

Power-off
Cabling problem between

the decoder/amp and the
audio speakers

EMI interference
Distance exceeded or

unusual cable attenuation

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.

Consecutively turn off other video sources to
determine which video source is the cause of
interference.
Verify cable grade. Use higher grade cable if
necessary. Reduce color intensity at monitor.

Check if the UTP pairs are split and correct.
Each signal pair must be twisted.
Check power supplies of digital audio
equipment.

Check audio speaker cabling.

Check that wiring is not too close to
transformers and ballasts.

Check cable distance and cable grade.
