I use BetaInnovations cards with FSUIPC and some home-made mapping software to translate lots of hardware inputs into FS events (eg lights, icing switches, Autobrakes plus all the usual stuff like analog throttles, flaps and spoilers)

All this is quite simple - the FSX offsets are published (you can see them in FSUIPC4) and since I'm already using FSinn for online flying I simply intercept the hardware inputs and send the appropriate offsets to FSX using FSCopilot.

Trouble is I can't find the correct offsets for the ND control panel. It must be possible - GoFlight have produce an EFIS control panel that does exacly this - has anyone in 'Homebuild World' tackled this? Can anyone tell me how to control the ND display using my own hardware?

Cheers
