VGA Cable

[Rene]

I am trying to make my own VGA cable. I understand that not all of the 15
pins are used. Could someone tell me what are the minimum pins that I have
to wire to make the cable work?



Thank you.

Pin 1=Red Video
Pin 2=Green Video
Pin 3=Blue Video
Pins 5-6-7-8-10 =Ground
Pin 13=Horizontal Sync
Pin 14=Vertical sync

Let us know how the video looks if you do it without coax. ;-)

Thanks,
Rich

This is probably another stupid question but, when I wire this thing
(computer VGA cable) up, pin 1 connects to pin 1, pin 2 connects to pin2,
pin 3 connects to pint 3 etc....



Is this correct, or is there something hidden that I don't know about?

I just helped my dad fit a little security camera. It has about 15m of
unshielded, untwisted 4-core cable (not coax) to carry composite
video, audio and power. Remarkably enough it actually works, and with
minimal interference.

That's correct. For best results, or for long runs, 75R coax cables or
twisted pairs will give better signal transmission for the RGB signals. If
you use coax or twisted pair, use pin 6 for red earth, 7 for green and 8 for
blue. If the signal source is a properly designed video output, this will
give you good results up to 40 metres or more. Pin 10 is usually used as
the signal earth for both sync signals and pin 5 is not normally required.
Some devices also use other pins for communication between PC and monitor.
Plasma screens, projectors etc don't use them so they can normally be left
unconnected.

Is this correct, or is there something hidden that I don't know about?

The cheap RatShack [1] extender cables are just wires. You get nasty
ghosts and edge effects with them. Very annoying.
