Hi Guys we cracked it!
It was stupidly simple in hindsight and works beautifully.
Thank you Mactec, Hui at DMM and Chris at Control Techniques for all your help.
Hope this helps someone else...
Thanks Mactec

i'll try and pick up some screened cable tommorow and wire it up - fingers crossed ha!
Hi Al thanks for the reply - That had/has me stumped too.
