Thread: cat5 VGA bauln

    cat5 VGA bauln

    Hey,

    I have a job coming up where I need to extend a VGA signal about 500'. I have been searching online and just haven't found exactly what I want. I am looking for one that will do the highest possible resolution at the greatest distance. Mostly for the future. This job only is probably going to run at 1024x768 or 1280x1024 at most but high definition in the future is a possibility. I am going to be making cat5 snakes that will be 250' each on reels so it has to be able to run at 500' or 750'. I am sure someone on here knows of a high quality one. I saw one that Media solutions had and I didn't write it down and can't remember what it is.. but it was able to do 1024x768 at 1500' which is about what I am looking for.

    Thanks,

    Ryan

    I use TV-One extenders - but on cat6 cable - seems to work better than some cheap cat5. specs: http://www.tvone.co.uk/cat5transpage.shtml
    limit is about 300m at 1280x1024.

    You wont find an HD VGA extender that works reliably over about 50m - use fibre, its not too expensive if you shop around. Think logical boxes are fairly reasonable (DVI and VGA) - theres loads out there..... I;ve just done a whole lot of research and still keep finding more....

    Incidentally - The Lindy DVI cat 5 extender works great up to 1600x1200@60Hz and is quite cheap too. Theres an HDMI one on its way in about 6 months I've been told. Couldnt believe the price of this one either: http://videogame.brando.com.hk/prod_...?prod_id=00506

    I would suggest Magenta Research stuff,
    I have used their multiview line on several shows.
    I will never go back to using normal video cable for anything longer than 50'
    - 1920 x 1200 resolution at 2000 ft.(610m)
    - 1600 x 1200 resolution at 1500 ft.(457m)
    - 2048 x 1536 resolution at 1000 ft. (305m)

    I would suggest this transmitter,

    and for the reciever,
    http://www.magenta-research.com/broc...000_AK1500.pdf

    That will easily get you the distance and resolution you need.

    Let me know if you have any questions.

    Those are the ones I was looking for! I submitted an "order" for a quote from them so hopefully they will get back to me tomorrow. Its probably easiest to go through them right?

    Last night I found Gefen's DVI FM extender and was looking into that, but getting fiber for a 1k budget will be hard. Plus I can just use the Cat5 cable for other projects. The adapter kind of looked cheap too.

    Thanks!!

    I would look at a fiber extender and DVI rather than VGA..

    a pair of these http://www.thinklogical.com/product.asp?ID=46

    and some ST fiber...

    Thinklogical boxes - possibly the greatest source of ire in our warehouse. Work fine in the warehouse. Don't work on site.

    DVI is not always the answer!!!...

    specially because in various projectors you loose the color control.

    yea I think for this particular project VGA is easier because the source is most likely a 1604 going to just a normal projector. In the future I would like to get DVI ones but its just going to cost too much for the budget I have. I am just going to get a set of the Magenta research multiview boxes. they are decently priced and seem to travel the farthest with actual distance ratings opposed to estimated ratings. Will getting shielded cat cable offer better noise rejection or is it really just a toss up?

    my guess would be shielded is better than non shielded. You mentioned cat6 instead of cat5 earlier, this probably wont matter, as these systems dont actually use ethernet, they are just using the cabling to get the signal from place to place, however the shielded cable will help with noise reduction over the run most likely.
