Intelix AVO-V3AD-F HDTV Component Video
and Digital Audio Balun Installation Guide
Introduction
The Intelix AVO-V3AD-F component video and digital audio HDTV balun
transmits a YPbPr (RGB) signal and digital audio over inexpensive structured
pair cabling, such as Cat 5.
Used in pairs, the AVO-V3AD-F supports 480i/p, 720p and 1080i/p resolutions
for hi-definition multimedia applications.
Installation
One (1) pair of baluns is needed to
complete one component (YPbPr) or
RGB connection via Cat5 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 digital audio. The pin
configuration follows the
EIA/TIA 568A/B standard. The
Intelix AVO-V3AD-F balun is
reverse polarity sensitive. Please
ensure that wiring is straightthrough.
2. Connect one AVO-V3AD-F
balun to the component video
coaxial cable output of the video source using three RCA video cables.
Ensure the color codes of the AVO-V3AD-F and video equipment match.
3. Connect a second AVO-V3AD-F balun to the component video coaxial cable
input of the receiver(s) at the remote end using three RCA video cables.
4. Complete the connection between the two baluns using standard Cat 5 twisted
pair cable. Verify the Cat 5 is terminated with RJ45 connectors on both ends.
Ensure that there are no split pairs or taps.

5. If digital audio is to be connected (optional), connect an RCA lead between
the balun and the digital audio equipment at both ends.
6. Power-on the component video equipment. Check the image quality and refer
to troubleshooting if the image quality is unsatisfactory.
