Quick Installation Guide
Overview
The Component/Composite Video Balun (500056, 500057) allows one component
video (YPbPr or RGB) signal and one composite video signal to be transmitted via a
cost-effective unshielded twisted pair (UTP) cable.
Used in pairs, the Component/Composite Video Balun supports 480i/p, 720p and
1080i/p resolution for hi-definition (HDTV) video applications.
The product allows four coaxial cables to be replaced by one Category 5E/6 twisted pair
cable, enabling standard structured cabling techniques to be used for more efficient
cabling.

Installation
One (1) pair of baluns is needed to complete one component/composite video connection
via a 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 Composite video. The pin
configuration follows the EIA/TIA 568A/B standard. The Component/Composite
Video 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 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 a 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 Composite Video is to be connected (optional), connect an RCA lead between
the balun and the Composite Video 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 table describes some of the symptoms, probable causes and possible
solutions in respect to the installation of the Component/Composite Video Balun:
Video Symptom Probable Causes 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.
