Quick Installation Guide

Overview

The Component Video/Analog Audio Balun (500052, 500053) allows one component
video (YPbPr or RGB) signal and one Analog Audio signal to be transmitted via a cost­effective unshielded twisted pair (UTP) cable.

Used in pairs, the Component Video/Analog Audio 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

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 analog audio. The pin
configuration follows the EIA/TIA 568A/B standard. The Component
Video/Analog 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 analog audio is to be connected (optional), connect an RCA lead between the

balun and the analog 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.

Troubleshooting

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

Video Symptom Probable Cause Possible Solutions

No continuity in video
link

Verify cable continuity between pairs of

baluns.
Power off Check power supplies of video equipment.No video
Improper connection
and/or swapped pairs

Check that baluns are connected to correct

video inputs and outputs.

Unusual colors Reversed polarity

Check wiring and ensure straight-through

polarity.

Background pattern EMI interference

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.

Smearing Exceeded distance

Verify cable grade. Use higher grade cable

if necessary.
Exceeded distance

Verify cable grade. Use higher grade cable

if necessary. Increase contrast on monitor.

Weak contrast

Unusual link attenuation

Verify cable distance using ohmmeter or

cable tester.

Image not stable

Defective link or
equipment

Verify video equipment interface integrity.

Horizontal bars moving
slowly

Substantial crosstalk
between multiple video
sources

Consecutively turn off other video sources

to determine which video source is the

cause of interference.

Snowy picture Distance is near limit

Verify cable grade. Use higher grade cable

if necessary. Reduce color intensity at

monitor.

Audio Symptom Probable Cause Possible Solutions

EMI interference

Check that wiring is not too close to

transformers and ballasts.

Poor audio quality

Split pair

Ensure that the UTP pairs are not split and

that each pair of wires is twisted.
No power Check your audio system for power.
Open circuit Check wiring to ensure continuity.No audio
Defective balun Change baluns for another pair.

Audio phase cancellation Reversed wires Check for straight-through wiring.

Audio weak

Distance specifications
exceeded

Check DC loop resistance and verify if

distance spec is exceeded. Reduce cable

length or eliminate high-loss components.
