Installation Guide
Introduction
The Quad Video Baluns allows up to four (4) composite video signals to be
transmitted via unshielded twisted pair (UTP) cable in a point-to-point connection.
Used in pairs, the Quad Video Balun eliminates up to four (4) coaxial cables, allowing
audio-video equipment to be connected via space-efficient and cost-effective
Category 5 twisted pair cable. The Quad Video Balun also works in conjunction with
other Black Box composite video baluns such as the IC440A and IC444A.
Installation
One (1) pair of baluns support four (4) composite video signals or one (1) component
video (YPbPr) and one (1) composite video signal via Cat5 twisted pair. To install the
baluns, perform the following steps:
1. Identify the pin configuration of the baluns. Four (4) twisted pairs are required
if all four (4) signals are transmitted. The pin configuration follows the EIA/TIA
568A/B standard. The Quad Video Balun is reverse polarity sensitive. Please
ensure that wiring is straight-through (Ring to Ring, Tip to Tip).
2. At the video source end, connect a Quad Video Balun to the video output using
the appropriate number of RCA or BNC-terminated cables.

3. At the video display end, connect a Quad Video Balun to the video input using
the appropriate number of RCA or BNC -terminated cables.
4. Complete the connection between the two baluns, using standard Cat5 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 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 Quad Video Balun. If you still cannot
diagnose the problem, please call Black Box Tech Support at 724-746-5500.
Symptom Probable Causes Possible Solutions
No video No continuity in video link Verify cable continuity between pairs of
baluns.
No video Power off Check power supplies of video
equipment.
No video Improper connection
Swapped pairs
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 (ie; 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.
Weak contrast 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.
