V1-CV Component Video Balun
Installation Guide
Introduction
The Intelix V1-CV Component Video Balun allows a single component video signal
(Y, Pb, or Pr) to be transmitted via cost-effective unshielded twisted pair (UTP)
cable. Three (3) balun pairs are required for one point-to-point component (YPbPr)
video connection. The product allows three coaxial cables to be replaced by one
Category 5 twisted pair cable allowing standard structured cabling techniques to be
used for neater and more streamlined cabling. The V1-CV is compact enough to
allow three (3) units to be connected side by side on the back of the component
video equipment.
Installation
Component Video (YPbPr) Connection:
Three (3) pairs of Component Video Baluns (six baluns) are needed to complete one
component (YPbPr) connection via Cat5 twisted pair. To install V1-CV baluns, perform
the following steps:
1. Identify the pin configuration of the baluns. One twisted pair is required. The
V1-CV is reverse polarity sensitive. Please ensure that wiring is straight-
through (Ring to Ring, Tip to Tip)

2. The V1-CV works in pairs. For each component signal (Y or Pb or Pr), plug
one balun into the component video output (coaxial) of the video source.
3. Plug a second balun into the each of the component video inputs (coaxial) of
the video monitor or receiver at the remote end.
4. Complete the connection between the two baluns, using standard twisted pair
cabling techniques as shown on the next page. Each balun must be connected
to its corresponding component video balun at the other end. For example, the
component video balun for the “Y” component at the output must be connected
to the component video balun for the “Y” component at the other end.
5. 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.

Composite Video (NTSC,PAL,SECAM) Connection:
One (1) pair of V1-CV baluns (two baluns) are needed to complete one composite video
connection via Cat5 twisted pair. To install the V1-CV baluns, perform the same steps as
listed above by connecting the Component Video Baluns to the composite video
input/output connectors of the equipment. 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 V1-CV.
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 least on one end.
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.
