What about the PDF installation instructions he mentions?

I've just taken delivery of a touch probe from this chap :-
http://www.machsupport.com/forum/ind...ic,5004.0.html
My knowledge of lektronix extends to red cable is + (usually) !
Can anyone who's fitted one or similar give an indepth method of connecting it before I let the smoke out???

The white wire is common, the red connects to your probe input pin.

3.5mm wiring.

I guess it comes with the miniature phono jack?
The circuit just shows a string of N.C. contacts so the correct polarity is only required for the LED to operate when the probe has touched off, you can't really screw anything up as if you had the wire pair crossed it would just mean the LED would not light.

Oooh!
Gotta get me one of those
Ok, now I know what the wires are . . . where do I put them???
This is the bit where the smoke comes out !
I've read that they need to connect to pin 11 of the parrallel port ?
How, What, Why, When, Where ?
This thread should help. Have a read and post back if still unsure

I really am a numpty when it comes to lektronix
Is Board 1.jpg what I'm plugging into?
If so, then I've modified a connector to fit Plug 2.jpg
Now the hard bit, I have 3 wires from the probe, Red, White & a naked shield Cable 1.jpg, will all 3 be used? What do I need to connect to the plug - Plug 1.jpg?
Pin 2-red & 3-white.
Take the shield to ground.
Your plug has only two active pins so if you have to find a ground for the shield.
As long as the socket you show has the same pin out as the second JPG.

I thank you all, I really am a complete numpty when it comes to lektronics.
Having read through the posts I salvaged a suitable connector from an old PC fan & sanded it down to fit, the problem of how to connect such tiny & intricate wires was solved by junking the supplied female jack connector & purchasing a replacement from Maplins where the wires could be soldered directly to the jack.
Plugged it in & fired her up, touching the probe illuminates the probes LED & the 'digitise' LED lights in Mach3's diag window. And no smoke !
Eureka, after a bit of experimentation with the Mach3 digitise wizard I've set it off on probing a complex part I've been wanting to copy for ages.
Although this probe is going to save me lots of money it's also going to cost me a lot too, it's going to take about 3 days to create a point cloud on this part so I'm looking to buy/build a simple 3 axis machine pureley for probing.
