Component Video / Analog Audio ProAV Balun

Quick Installation Guide

Overview

The Component Video/Analog Audio ProAv BNC Balun (500052-PRO-BNC) and its

RCA version: the Component Video/Analog Audio ProAv RCA Balun (500052-PRO-

RCA), allow one component video (YPbPr or RGB) signal and one Analog Audio signal to be transmitted via a cost-effective unshielded twisted pair (UTP) cable.

The 500052-Pro-BNC and the 500052-Pro-RCA feature Ethercon  RJ45, ruggedized cast aluminum enclosure and built-in 12-inch (30cm) heavy duty AV cable leads for the demanding professional environment. They may be used in pairs or in conjunction with other MuxLab component video baluns.

Used in pairs, the Component Video/Analog Audio ProAv BNC Balun (or the

Component Video/Analog Audio ProAv RCA Balun) supports 480i/p, 720p and 1080i/p resolution for hi-definition (HDTV) video applications.

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 BNC (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 a BNC (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

No video

Unusual colors

Background pattern

Smearing

Weak contrast

Image not stable

Horizontal bars moving slowly

Snowy picture

Probable Cause

No continuity in video link

Power off

Improper connection and/or swapped pairs

Reversed polarity

EMI interference

Exceeded distance

Exceeded distance

Unusual link attenuation

Defective link or equipment

Substantial crosstalk between multiple video sources

Distance is near limit

Possible Solutions

Verify cable continuity between pairs of baluns.

Check power supplies of video equipment.

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.

Verify video equipment interface integrity.

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.

Audio Symptom Probable Cause

EMI interference

Poor audio quality

Split pair

No audio

No power

Open circuit

Defective balun

Audio phase cancellation Reversed wires

Audio weak

Distance specifications exceeded

Possible Solutions

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

Ensure that the UTP pairs are not split and that each pair of wires is twisted.

Check your audio system for power.

Check wiring to ensure continuity.

Change baluns for another pair.

Check for straight-through wiring.

Check DC loop resistance and verify if distance spec is exceeded. Reduce cable length or eliminate high-loss components.
