View Full Version : Component to Cat5

OK. Now that we have this area I can post my question.

To make a long story short.

The other day I was on a job where another company used these snap in connectors that had RCA connectors on one side and cat-5 on the other. A short component cable connected the AVR to the wall plate and cat-5 between the wall plate to behind the TV where it was converted back to component. These are passive connectors, not a powered balun that converts it to digital and back to analog. Anyone ever done this or seen anything like this?

The picture was viewable and there was a lot going on and I didn't pay too much attention to the picture which was the main menu of a DVD. I would expect that there wouldn't be enough bandwidth there to display a decent picure.

A balun in and of itself is a passive (unpowered) device.

It's just a BALanced (twisted pair) to UNbalanced (coax) transformer. I first used them 20 years ago for data terminals - IBM 3270 type to be precise. Something like 20/Mbs over a single twisted pair up to 300 feet.

What is the purpose of all this conversion in cbl type bck in forth?

HMMM.

Ive scene/touched cat 5 used in central closet distribution and also to server hubs for audio (ph system hold music/XM ect)for audio only on Large VOIP systems recently. (and yeah i admit it, i was a lost puppy at first, but damnit i made the thing work and Then some.;) ... it just all that "why" that kills me , while thinking "im a KNow it all" i guess:rolleyes:)

I dont understand the reasoning of "why" as you described above with all the conversion back and forth between cbl type = Lost and scratching my head in understanding and actual purpose.


Simon and what your(SKiid) eyes saw seem to be "up on this" way, way beyond I , how 'bout some laymans terms while you teach! (lol).

(btw this i what i wanna see more of in this forum> thanx guys for simply making me scratch my head... now thats Healthy!:) )

It's because that is what the original electrician had put in the wall during construction. (The cat-5). The TV is up above the mantle on the fireplace and the outlet is on the same wall but all drywalled. The new electrician called me and asked me if the cat-5 could be used for the Tv. I told him yes, we could use it but it would cost about $500.00 for the HDMI baluns. He asked if he could just run some coax. I told him I had something better, Monster component in-wall sheathed cable. He picked it up from me and put it in the wall. I was going out to terminate that wire when I came across this other company using the method I described above.

I didn't post all this detail before because, well because it is a lot of typing.:D

I wish servoman or stereohighficenter were here.

(guys from anther board)

ahhh i see.

After this AM's post (and thought) i Have saw/recalled something as you described similar in a structured wire home of high High end magnitude (didnt do the job btw) and i just didnt understand the reasoning. (still dont) nor to be honest did i wanna fool with it.;) I walked myself to death surveying the place and still didnt understand (lol). I think the Number i "put out there" for all the sat signal distribution(mirror lines/fishes galore) was enough to scare him off and keep me Sane!:)
(IE: ?WTF is all this crazy mess?)

Maybe I have no clue what I am talking about, but these people signed up for SBE today and when I saw what they mfg. I thought of this post. www.lynxbroadband.com

I've seen such a device, and it had a label of MUXLAB on it. It was an s-vid to cat5. It was in a closet for the AV system. Problem was, I was putting in a 211 and this was the only connection to the TV and it was also through the surround sound system. So, being it was just a fulfillment order, I hooked it up to the surround sound via svid. It had a herringbone near the top of the pic and it was only 480p. I made that customer sign off that we don't warranty any system that doesn't have a co-located TV or if other company's connections are used.

This company makes the electronic baluns which are the way to do it and we use these often. My original post was about a mechanical connector-rca/cat5.

Muxlab is the answer for all things passed over CAT5E.
We use them all the time on many a commercial installation. One customer in particular needed to have TV's all over the building run from a single location. The longest run was around 1500 feet from the source. All the TV's are run using CAT5 and baluns. Some are HD feeds, other from PC, again all using baluns on each end.
PQ is excellent with little loss. We even used a powered hub that increases the distance to 2500 feet, just to make sure the longest run is just as good as the shortest one.

Is it 1 cat 5 for both A & V?

And its a lot cheaper than running RGB Coax. There are probably 15 or 20 different manufacturers of the Component baluns now. I've been using Intelix but after I use up my current inventory I'm going to try Muxlab.

Don't any of you guys run HDMI over CAT5? This is about all we do any more in large complex systems.

Now I know that that requires 2 cat 5s.

I've got one for sale if someone wants it. I'll sell it just to get my money back. I got it far aclient that has messed up wiring. We ended up using RG-6 for component.

I would consider this for a home theater environment, but for commercial installs I'd stick with component (via Cat5). The beered up viewing audience isn't as critical. :)

http://www.muxlab.comThanks. They do have a balun for component with analog or digital audio on one CAT5. And welcome to our humble board. he he he.

MuxLab and Niles both make Cat5 to SVideo, Stereo Audio, Component, etc. baluns. Prices seem to be comparable at dealer cost.

We have used both brands in a DIRECTV 13 HDTV receiver sports bar installation with great results. Cat5 in this install was preferable to RG6 due to number of cable runs and cosmetics. MuxLab product has advantage of R/G/B pigtail already attached to balun eliminating another set of wires and possible connectivity issues.

You can do audio and video connections by simply adding another Cat5 cable for maximum flexibility.

If you step up to cat 6 wire, you substantially increase the distance length of runs. An obvious plus in some situations.
