Muxlab Dual S-Video Balun - Manual (Page 2)

© MuxLab Inc.
Installation
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.
Troubleshooting
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
Verify cable continuity between pairs
of baluns.
Power off
Check power supplies of video
equipment.
No video
Improper connection and/or
swapped pair 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 (i.e., 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.
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.
