Chris,

I've made a Macro in ActiveHome and set it to A6. Now when I trigger an A6 ON signal, it will then send A1 ON, thus turning on the SwitchLinc. This works fine but I will not be able to use remote dimming because the macro is either on or off. I'll try to plag the IR543 somewhere else and un-hook all the surge suppressers and UPS and try it.

Thanks for your help and I'll let you know. I will probably get a Maxi Controller to play around with it.

Simon
