    After spending loads on my hcpc, i am looking to "upgrade" the no brand vga cable to hook up my hcpc to my Barco Graphics 808s.
    Any ideas where i could get one,i am tempted to build my own with some Van damme 5 core professional vga cable available from Maplins but it looks rather large in diameter (18mm) so i don't think it will go into the 15pin dsub connector easily??
    Is there any benefit in using the 9 pin dsub on the PJ?
    Also can someone tell me the pin config for vga (15 pin dsub)
    Any help as usual greatly app'd
    Tim
    :D

    Believe me when I say this is a pain in the arse cable to try and make. I did one with nutter thick 75ohm cable and married all the earths together outside the plug before attaching them in. Very hard to do and it didn't stay working for long.....

    I now just order hi-quality ones which I supply.

    PIN CONFIG AS FOLLOWS

    1= red
    2=green
    3=blue
    4
    5
    6= red ground
    7= green ground
    8= blue ground
    9
    10= ground
    11
    12
    13= H sync
    14= V or composite sync

    Have fun!

    Hi Gordon,

    Congrats BTW on your recent change of erm erm status :D
    (how much kit you got left :D )

    Right....how much is this cable approx 10meters in length with a 15 pin dsub breaking out into 5 BNC's all to include p&p etc

    Thanks

    Tim:p

    Bit of practice for you first.

    Get an octopus (live) and a string bag (large hole variety).
    Your goal - get the octopus into the bag and all the legs.

    Pretty much as easy as soldering a 15pin connetor.

    My advice is to buy at least three of the VGA connectors.

    The vandamme cable is about as good as video cable gets.

    Come back and let us know how many expletives it took.

    I recently had to convert a 15pin D cable to the Barco 9pin D.
    I use the 5 BNC input with my Quadscan Elite. The QSE does have a VGA pass through. But it is on the other side of the room. Meaning i would have to run the Computer VGA cable all the way to the QSE, then the signal would have to go all the way back to the projector!.

    Anyway!.

    The best way to solder to 15/9 pin "D" connectors, is to first "tin" the ends of each wire to be connected. By tin i mean "pre solder the ends" etc. That way you will not have stray strands hanging about.
    Next, pre solder the pins on the 15/9 pin plug. That way everything already has some solder etc.

    IMPORTANT!!!.....If the plug has a cable to plug"shroud" put it on the wire first!. The amount of times i've soldered plugs only to remember "after" i've finished!.

    Its best to solder all the positive(inc H. V.) wires first.
    Make sure the plug is held securely! (a vice etc).
    Hold the wire to be soldered with some long nose pliers. This not only makes it easier but stops the wire/soldering iron from burning your fingers!.

    Put the iron on the "pre soldered" pin to be soldered.
    When you can see the solder melt, push the "presoldered" wire into the pins hole. Hold the wire steady and remove the iron.

    Repeat for all the other wires.

    Next twist all the cables earth wires around one long earth wire. Solder these together leaving one long one, to earth to the earth pin etc. Pre solder the end of this just like the others, and solder the same.

    Re-assemble the plug, including any cable shroud(you did remember to put it on the cable first?).


    Above is only a guide on how i do it. I spent many hours trying to hold the wire/solder/iron at the same time and it can't be done without either burning the plastic plug/wire/yourself!.;)

    Oh i should add!.
    Gordon supplied me with a 15pin to 5 BNC 10 metre cable for my Quadscan. and it is excellent quality.

    I'm tempted to order a 15pin to 9pin 10 metre cable from him, for use with my HTPC!. This is because although i could make one myself, it wouldn't be any cheaper by the time i bought all the quality cable/plugs etc.

    Gordon, if you read this email me with a price please!. I can supply the "9" pin layout if needed etc.
