Hi Col,

Hope I can help. The twinflex wires connect to pins 2 & 21 on the Parallel Port plug.

The signal lead is soldered to pin 2, and the ground lead is soldered to pin 21.

Doesn't look familiar in that black case, Col, but I have found the wiring diagrams for you.

You'll have to open up the case to see which wire colour is which.

2 different diagrams from 2 different sites,

Pic 1. is Toucam (older model 740k)
Pic 2. is Toucam ProII 840k

Col, inside the case at the end of the cable from the Parallel port, can you see the colours of the wires. And if two of them are cut of so they don't connect to anything?

P.S. It would get here quick. Cheryl ordered my Birthday present from England and it got here to our little country town in Australia in 4 days!!!! But don't send it, I can't do electronics either

see if you can see any numbers on the black thing next to where the wires are soldered on. Then you should be able to match them up to the wiring diagram above.

Little col, this is sure hard to do from a distance. If I was there with my multimeter and soldering iron, we've have it fixed in no time.

However, let's give it a go!

From your out of focus pictures, it look like only two wires were connected to the parallel plug. Pin 2 is the one top right (two pins in) - the other is pin 21. (Count from right to left along top, then continue from right to left along bottom - you hit pins 2 and 21 where the wires have come off). That is also what the wiring diagrams state. I cannot really be sure, but there are no other pins are there? The phot shows something black/blurry around pins 4 and 5 - what's that?

Now, looking at the out of focus picture of the wires that have come off, it looks like it's the red and yellow wires that have come off. The white doesn't look to have broken and I cannot see a black??

OK, two options. First is quick and dirty - connect red and yellow in any order to pins 2 and 21 and see if it works? If not, power off, swap them over and try again. One way should work. No promises now, but I don't think that reversing them will blow everything up! If I was to have a bet, I'd guess the red wire would be the signal and would therefore go to pin 2.

The second option is much harder for you - will be a snap for anyone with a bit of electronics knowledge. A quick search around the rat's nest of wiring inside the box and they will soon know which colour is 0V and which is signal. But you could work it out if you took your time and drew a picture of what was connected to what, where that parallel cable comes into and connects to the board. If you can do that, post the diagram and we'll see if we can work out what it means.

Good luck
Eric
