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.
