Quick Installation Guide

Overview

The S-Video-Audio ProAV Balun allows one S-Video signal and one stereo audio
channel to be transmitted via an unshielded twisted pair (UTP) cable in a point-to-point
connection for more versatile cabling.

The 500017-Pro features Ethercon  RJ45, ruggedized cast aluminum enclosure and
built-in 12-inch (30cm) heavy duty AV cable lead for the demanding professional
environment.

Used in pairs, the S-Video/Audio ProAV Balun eliminates costly and bulky S-Video
and audio cable, allowing S-Video equipment to be connected or moved to any
convenient modular outlet. The S-Video/Audio ProAV Balun also works in conjunction
with MuxLab’s Audio/Video Distribution Hub (500200) to allow S-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 is needed to complete one composite stereo audio-video

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

1. Identify the pin configuration of the baluns. Two (2) twisted pairs are required for
S-Video and two (2) twisted pairs are required for stereo analog audio. The pin
configuration follows the EIA/TIA 568A/B standard. S-Video-Audio ProAV 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 S-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 S-Video-Audio ProAV Balun 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. 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 S-Video-Audio ProAV Balun:

Verify cable continuity between pairs of baluns.

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.

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