Component Video/Digital Audio Balun

(IC469A, IC566A)

Installation Guide

Introduction

The Component Video/Digital Audio Balun (IC469A, IC566A) allows one
component video (YPbPr or RGB) signal and one Digital Audio signal to be
transmitted via cost-effective unshielded twisted pair (UTP) cable. Used in pairs, the
Component Video/Digital 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 5 twisted pair cable allowing standard structured
cabling techniques to be used for more efficient cabling.

Installation

One (1) pair of baluns are needed to complete one component (YPbPr/RGB) connection
via Cat5 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 Cat5 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 diagrams show a couple of typical applications .

Troubleshooting

The following tables describe some of the symptoms, probable causes and possible
solutions in respect to the installatio n of the Component Video/Digital Audio Balun.
If you still cannot diagnose the problem, please call Black Box Tech Support at 724­746-5500.

Video
Symptom Probable Causes Possible Solutions

No video No continuity in video link Verify cable continuity between pairs of

baluns.

No video Power off Check power supplies of video

equipment.

No video Improper connection

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 sources (ie;

wireless, switching psus) Try to isolate
them from the video. Use shielded
twisted pair grounded at both ends.

Smearing

Exceeded distance Verify cable grade. Use higher grade

cable if necessary.

Weak contrast 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.

Digital Audio
Symptom Probable Causes Possible Solutions

No audio Distance exceeded Verify cable length between the two

baluns.

No audio Split pair Check if the UTP pairs are split and

correct. Each signal pair must be twisted.

No audio Power-off. Check power supplies of digital audio

equipment.

Missing channels Cabling problem between

the decoder/amp and the
audio speakers.

Check audio speaker cabling.

Noise, static EMI interference. Check that wiring is not too close to

transformers and ballasts.

Noise, static Distance exceeded or

unusual cable attenuation

Check cable distance and cable grade.
