Please log in for more thread options 1. I have Cat-5e cables for my home telephone so there are four (two pairs) wires unused. Can I used these four wires for S-video with Leviton S-video Quickport (http://www.smarthome.com/865166.html) without interference with telephone ? 2. Can I run a single Cat-5e for both S-video and audio with Leviton S-video and RCA 110 type Quickports without any interference ? Thanks in advance. | ||||||||||||||||

I've never shared a cable between a phone line and an S-Video, but I can imagine that, due to considerable difference in operating frequencies, you will see no picture degradation. However, it is really worth mentioning that the ring can generate 100V potential on one of the pairs in this cable, so you will feel much safer if you use a whole different cable for your audio/video stuff. S-video and stereo audio run just fine on CAT5E for just about 100 feet. I haven't tested further without a balun, but if you need to go several hundred feet, you can purchase a couple of baluns (impedance matching transformers) for both ends of that cable, and send the signal without any quality degradation on 500 feet or more. -- Dmitri Abaimov, RCDD http://www.cabling-design.com Cabling Forum, color codes, pinouts and other useful resources for premises cabling users and pros http://www.cabling-design.com/homecabling Residential Cabling Guide ------------------------------------- ##-----------------------------------------------## Article posted with Cabling-Design.com Newsgroup Archive http://www.cabling-design.com/forums no-spam read and post WWW interface to your favorite newsgroup - alt.home.automation - 63 messages and counting! ##-----------------------------------------------## | ||||||||||||||||
