Scart over Cat 5e
I have a Virgin Media V+ box. It has a copy to VCR Function which
outputs a recorded programme (Stored on the internal HDD) via a scart socket on the box, which should be connect to a VCR/DVDR. I would like to transfer this to an upstairs room. I already have a spare Cat 5e (4 twisted pairs) cable running between these rooms. It is not possible to run any more cables, as I installed these cables when building an extension. Is it possible to solder the pins I require from the scart lead to a Cat 5e cable to transfer this signal upstairs and then back to scart. i realise that SCART has 21 pins and I only have 8 wires available, but I just want a basic picture and would even settle for mono sound if required. Has anyone ever done this.... and what pins must be connected to give sound and vision? TIA |

I wouldn't p*ss about with the current wiring, soldering SCART ...
http://www.macfh.co.uk/JavaJive/Audi...ART/SCART.html .... is very fiddly ... http://groups.google.com/group/uk.te...bf0a9a9d65bd5c Some alternatives: Wireless (no RGB?): http://www.amazon.co.uk/Marmitek-Inv.../dp/B000MFK2OC SCART to CAT5: http://www.nexxia.co.uk/Audio_Connec...o1 QwodAwRqlg http://www.connectivity.avocent.com/...

TIA Doing this as you suggest will not produce an acceptable result, there are lots of adapters on sale for doing this. Just type 'cat5 video' into google, you'll get a lot of relevant hits. |

Don't believe one word of the claims about the range being 50 or 100 meters. Usable range is only up to 6 meters indoors and if you go any further noise and distortion will be plainly obvious. If he's going to run a cable from one room to the other then why not use Cat 7 cable which is screened and use S-Video instead of RGB which together with stereo audio only requires 4 main wires and a common ground. http://en.wikipedia.org/wiki/SCART http://en.wikipedia.org/wiki/Category_7_cable -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..

Has anyone ever done this.... and what pins must be connected to give sound and vision? TIA CAT 5 is rated to a fairly high frequency so give it a go. Use one twisted pair for composite video, one for left and another for right audio and use the spare pair possibly use it for the remote control or scart control voltage. You will need to work out your own colour code. But attach one half of the twisted pair to the screen / earth. If the picture looks good to you then continue to use it. If it picture quality is poor then you might need to look at buying a video sender. It is up to you. |

If both devices have S-Video available on SCART you'd have enough for that too. But you'd not have any of the auto switching a SCART normally provides.

Has anyone ever done this.... and what pins must be connected to give sound and vision? The pin-outs are found on many sites. Try Wiki. If you use composite just make sure that you use a twisted pair for video, another for audio L, and another for audio R. You would have enough conductors for RGB if you used the same ground for all the colours. That might work or it might not!. Since you are not going to send any video or audio in the other direction crosstalk won't be a problem. CAT 5 will handle the video alright for a short run, because a lot of CCTV links use four core alarm cable. It can get a bit smeary above 7 or 8 metres though. I should give it a whirl. Bill |

That's a worse case of course because the bluetooth is using the same frequency band as the oven's 600w of RF output. The video signal in the cable will be interfered with by the switching PSU with its nasty harmonic outputs radiated from its case and back down the mains supply cable. |

We know one that caused some radishes to go soggy in three days when left in a bowl nearby .. and yes we repeated the experiment which ended with it going to the menders where it was pronounced as very leaky indeed and thence it went to the tip... Another one took out an industrial grade Western Multiplex 2.4 Ghz link when the dish within 100 metres and solid metal and facing the other direction was badly affected!.

I built the leakage detector as a project in one of the electronics mags. ISTR it was calibrated such that FSD was the legal emissions safety limit, my meter registered about 20% FSD when held against one part of the door. (Can't remember what the exact figures were). I'm not too worried, I'm still alive, and so are my parents, the microwave oven (a Belling) went on working until 1992, nothing they have had since has lasted that long, worked as well, nor been as easy to use. -- Mark Please replace invalid and invalid with gmx and net to reply. www.paras.org.uk |

I can't vouch for the audio quality but the video is fine. -- Clint Sharp |
