Pins on VGA Cable |
When making your cable, the first thing to do
is to identify the pins on the connector. If you look closely
at the pins you will see tiny number next to the pins. These
are the number of each of the wires in the connector. Cut one
of the ends off of the cable. If you have hoods that can be
removed, then you can identify the wires that connect to each
pin. If you have molded cables, then you need to identify the
wires by another method. |
| One way to do this is to use a continuity tester
or just use a small 5 or 12 volt DC light. Hook one end of the
light to a wire on the cable. Hook the ground from an appropriate
power source to the other end of the light. Then put a wire
on the pos end of the power source. You can then use this wire
as a testing lead on each pin. when the light lights up, you
then know which pins that wire is attached to. Do this to identify
wires 1,2,3,5,13,14 in your
cable. |

Depending on how the connection on you monitor is, you must
now make a connector that can connect to you monitor. I still
had the original wiring harness so I just cut off the ends
and spliced the wires. You may be able to buy or get MOLEX
connectors that will work with your monitor.
Here is how the wires connect on MY monitor. Yours may be
very different. There are 2 pin connectors on the monitor
main board. Looking at the back of the monitor, the front
most pin connector is a 6 pin connector. They are... from
RIGHT to LEFT red, green, blue, gound, POS. V-sync and POS.
H-sync. The 3 pin connector is from RIGHT to LEFT - 1st pin
is not used. 2nd is NEG. V-sync and last is NEG. H-sync. You
only use the positive OR the negative sync connectors. I used
the negative ones because that was how the original game was
connected. IF you monitor has only one sync connection you
will have to twist the 2 sync wires together and connect then
to the 1 pin on the monitor.

Adjustment Disk |
After you get the correct signal going to you
monitor, its a sure bet you will have to adjust the monitor.
These little disk thingies will adjust things like vertical
hold, vertical linierity, vertical height, horizontal hold,
and horizontal frequency. the can be adjusted by turning the
little tab inside. There are also tabs for horizontal and vertical
centering. These can be adjusted by moving a wire to one of
3 positions. Adjust all of these to get your picture looking
great. Click image to see a close up. |
Color adjustments |
There will also be knobs or something to adjust
color levels. Usually one for each of red, green, and blue.
These are usually on the PCB that is attached to the neck of
the monitor at the rear. There will also be adjustments for
overall brightness (intensity) and sharpness (focus). |
