Single Composite Video Balun System. Model # BLN-8810

Balun System

This balun system allows installers to take advantage of Cat5 (or higher) cable for interconnecting AV components over long distances. Common signal formats such as composite video, RGB component video, S-Video and line level audio can easily be sent over UTP cable for considerable distances. This is useful in retrofit applications as it takes advantage of unused pairs of Cat5 data cable already in place. In new construction, take advantage of the smaller size and lower cost of Cat5 cable when distributing signals throughout the structure. Each balun accepts standard RJ45 male connectors, is completely passive and requires no power. Each unit is clearly labeled to identify which RJ45 connector pair is used for the designated signal path.

Wiring

The diagram below illustrates the wiring layout of standard RJ45 connectors in Network applications. Note that pairs exist between pin #4/5, #3/6, #1/2 and #7/8. When looking at an RJ45 connector from the bottom, with the spring tab facing down, pin #1 will appear on the left.

Distance

Actual usable maximum distance between these baluns will vary on a number of factors including strength of signal, quality of terminations and local sources of interference. The distances listed are based on use of Cat5 cable, and should be considered an absolute minimum. Depending upon the size of the video monitor, and level of required video signal. usable distance will likely be much greater. Distances will increase with Cat5e, Cat6 or higher rated cable.
