Iain and Newbryford - many thaks for your responses. This is my first layout and the first time I have tried to add an accessory to the Ace v3.2.
Your instructions worked perfectly, I had got my knickers in a twist about when to have the IP set to SET and when to RUN whereas it is, in fact, very simple!
IP RUN, enter address on ACE, switch IP to SET, activate turnout left and right on ACE, switch IP to RUN, IP now moves on address selected
So once again thanks gents
Cheers Steve
