Quick Installation Guide

Overview

The Dual S-Video Balun allows up to two (2) S-Video signals to be transmitted via an
unshielded twisted pair (UTP) cable up to 1,000 ft (305 m) in a point-to-point
connection. The Dual S-Video Balun fully utilizes the Cat 5E/6 cable and works in
conjunction with MuxLab rack, wall and surface mounting accessories for more cost
efficient cabling.

Installation

Troubleshooting

One (1) pair of baluns is needed to complete one dual S-Video connection via Cat 5E/6

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

1. Identify the pin configuration of the baluns. Four (4) twisted pairs are required; one

(1) pair for each S-Video channel. The pin configuration follows the EIA/TIA
568A/B standard. The Dual S-Video Balun is reverse polarity sensitive. Please
ensure that wiring is straight-through (Ring to Ring, Tip to Tip).

2. Connect one (1) balun to the S-Video outputs of the video source using S-Video

jumper cables (not included).

3. Connect a second Dual S-Video Balun to the S-Video inputs at video screen or

receiver at the remote end using S-Video jumper cables (not included).

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.

The following table describes some of the symptoms, probable causes and possible
solutions in respect to the installation of the Dual S-Video Balun:

Video Symptom Probable Cause Possible Solutions

No continuity in video link

No video

Unusual colors Reversed polarity

Background pattern EMI interference

Smearing Exceeded distance

Weak contrast

Image not stable Defective link or equipment

Horizontal bars moving
slowly

Snowy picture Distance is near limit

Power off
Improper connection and/or

swapped pair

Exceeded distance

Unusual link attenuation

Substantial crosstalk between
multiple video sources

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 straight­through 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.
