Making a monitor cable...

By cyberghost_1 ·
I have a project, to make 2 monitor cables. One 40 cm and the other 60 cm long. I have the male and female ends..15 pins. The problem is that I was given an 18 wire cable not 15...can it still be done? What colors go where, what colors can I leave un-saudered? Yes I have the sauder too.
Am I missing any details?

Hi,

Sure you can use an 18 wire cable, just don't use 3 of them (maybe cut off short to keep them out of the way.
Be careful when soldering the wires, the male and female ends are mirror images, ie pin 1 is at opposite ends of the plug.

Colours aren't important, as long as a particular colour on one end goes to the same pin on the other end.

What I do is to try and stick to the resistor colour code values and link with the pin number.

Resistor colour code

black = 0
brown = 1
red = 2
orange = 3
yellow = 4
green = 5
blue = 6
violet = 7
grey = 8
white = 9

Your cable probably has wires with stripes as well as solid colours.

If there is a braided shield, then this is soldered to the metal case of the plugs, to provide an earth shield connection.

Don't get too hung up on the colours. Unless your have twisted pair cable and need to run data through them its not a problem.
What I would do is stick to the resistor colour code like this:

red, red/black, red/brown etc, then orange, orange/black and so on using whatever colours you have in the colour code sequence.

A tip to ensure that both ends match, plug your male and female connectors together before soldering, then each end of the wire can be soldered to mated pins.

A general soldering tip:
Firstly strip each wire and tin it (apply fresh solder, but not a blob )
Then place your solder into the solder cup of the connector pin and briefly touch it with the soldering iron, this will tin the cup and lightly fill it with solder. Do all cups first. Place the tinned wire onto the filled cup and briefly touch with the soldering iron to melt all the solder and connect the wire.
I would suggest that you use plastic or other insulating sleeving to cover the soldered joint, to prevent the possibility of shorts. Place the sleeve over the wire prior to soldering to the cup.

Thanks you helped me greatly...I do admit that I should have listened to the last part about covering the soldered joint. I went through about 2 sets of cables (since they had to be a certain length) The rubber on the cables kept melting and the solder kept running to other joints...you could imagine the mess. I also went through 2 Male ends and 1 Female end..HAHA...THANKS AGAIN

Here is the problem, these are the colors my wire has...Red, Red/Black, Red/White, Black, Black/White, Black/Green, Green, Green/White, Green/Black, Blue, Blue/White, Blue/Black, Yellow, Yellow/Black, Yellow/White, White, White/Green, White/Black...18 wires total...and yes it is wire braided. So as long as the colors are the same on both ends I should not have any problems???

Who gave you a project of making monitor cables?
You can get them in just about any length you want. I just can't see sitting there trying to match up 15 wires on each end when I could order them using point and click.

The thing is, my boss want me to make 2 short cables, 1 40cm and the other 60cm. It is cheaper to get the individual parts than the premade cable...he is weird that way...I told him to order the premade ones, but he whined about shipping and how long it would take, then the lenghth and so on...
