500058 Component Video/Stereo Audio Balun

Component Video / Stereo Audio Balun

500058

Quick Installation Guide

Overview

The Component Video/Stereo Audio Balun (500058) allows one component video
(YPbPr or RGB) signal and one (1) Stereo Audio channel to be transmitted via a Cat
5E/6 twisted pair cable for more cost-efficient cabling. The product features Ground
Loop Coupling (GLC) to help eliminate “hum” bars. Used in pairs, the Component
Video/Stereo Audio Balun supports high-definition resolution and true left/right stereo
audio for hi-fidelity commercial and residential AV applications. The 500058 is not

compatible with part numbers 500050/51/52/53/54/55/56/57.

Installation

Troubleshooting

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

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

1. The pin configuration must be according to EIA 568, either A or B and wired

straight-through (no crossover).

2. Plug one (1) balun into the component video output of the audio-video source

according to the color code of the RCA cable leads and jacks.

3. Repeat step 2 for the second balun at the display side.

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,
ensuring that there are no split pairs or taps.

5. If Stereo Audio is to be connected (optional), connect left/right RCA jumper cables

between the balun and the stereo 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-Stereo Balun:

Video Symptom Probable Cause Possible Solutions

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

No video

Unusual colors Reversed polarity Check wiring and ensure straight-through polarity

Background pattern EMI interference

Smearing

Weak contrast

Image not stable Defective link or equipment Verify video equipment interface integrity.

Slowly moving noise or
horizontal bars

Horizontal hum bars
moving slowly

Snowy picture Distance is near limit

Poor image EMI interference

Power off Check power supplies of video equipment.
Improper connection and/or
swapped pair

Exceeded distance or faulty
UTP cable or crimping

Exceeded distance

Unusual link attenuation Verify cable distance using ohmmeter or cable tester.

Missing ground (GND)

Substantial cross-talk
between multiple video
sources

Check that baluns are connected to correct video
inputs and outputs.

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. Use higher grade cable if necessary.
Verify cable grade. Use higher grade cable if

necessary.
Increase contrast on monitor.

Ensure that at least the video source or display has a
3-prong AC power plug, grounded antenna coax
cable or any grounded device in the link that can
help clear up the interference.
A single ground in the link is recommended.
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 that wiring is not too close to transformers,
ballast’s, air conditioners, RF transmitters or similar
equipment.
Use of power conditioner may help.

Audio Symptom Probable Cause Possible Solutions

No audio

Missing channel

Noise, static

Missing continuity in the
circuit
Power-off Check power supplies of audio equip.
Cabling problem between
the sound source and the
audio speakers

EMI interference

Distance exceeded or
unusual cable attenuation

Verify and correct the circuit.

Check audio speaker cabling.

Check that wiring is not too close to transformers,
ballasts, air conditioners, RF transmitters or similar
equipment.
Check cable distance and cable grade. Also lifting
GND on transmitter or receiver side may help.
