VideoEase Component Video Balun (500021)

Installation Guide

Introduction

The VideoEase 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 Component Video Balun 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 the VideoEase
Component Video Baluns, perform the following steps:

1. Identify the pin configuration of the baluns. One twisted pair is required. The

Component Video Balun is reverse polarity sensitive. Please ensure that wiring
is straight-through (Ring to Ring, Tip to Tip)

2. The Component Video Balun 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 below. 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 Component Video Baluns (two baluns) are needed to complete one

composite video connection via Cat5 twisted pair. To install the VideoEase Component
Video 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
