Stereo Balun with Video (IC569A)

Quick Installation Guide

Overview

The Stereo Balun with Video (IC569A) allows a single composite video signal to be

transmitted via unshielded twisted pair (UTP) cable up to 2,200 ft (670m) in a point- -to

point connection. The IC569A features full audio bandwidth response for high fidelity

applications and features built-in color-coded cable leads for ease of installation. The

IC569A also works in conjunction with Black Box’s Audio-Video Distribution Hub (p/n

IC445A) to allow composite video programming to be distributed via UTP. Applications

include; classroom video distribution, commercial and home audio/video systems, hospital

video training, video conferencing, and video kiosks.

Installation

One (1) pair of baluns are needed to complete one composite stereo audio-video

connection via Cat5 twisted pair. To install the baluns, perform the following steps:

1. Identify the pin configuration of the baluns. One (1) twisted pair is required for

composite video and two (2) twisted pairs are required for stereo analog audio.

The pin configuration follows the EIA/TIA 568A/B standard. The IC569A is

reverse polarity sensitive. Please ensure that wiring is straight-through (Ring to

Ring, Tip to Tip).

2. Plug one (1) balun into the composite video/stereo audio output of the video source

according to the color code of the RCA cable leads.

3. Plug the second balun into the composite video/stereo audio 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. Power- -on the audio 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 IC569A. If you still cannot diagnose the

problem, please call Black Box Tech Support at 724- -746 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 frequency

sources (ie; 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.

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.

Audio

Symptom Probable Causes Possible Solutions

Poor audio quality EMI interference. Check that wiring is not too close to

transformers and ballasts.

Split pair Ensure that the UTP pairs are not split

and that each pair of wires is twisted.

No audio No power Check your audio system for power.

Open circuit Check wiring to ensure continuity

Defective balun Change Stereo Hi-Fi/Video 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.
