Sorry if this is a bit OT for this thread, but in short: Why bother with the Ortho Remote?
I have tried to make it work for quite a while and could not achieve the results I was aiming for.
Have you heard of/tried RooExtend?
It just works without any fuss using either a MS Surface Dial or other hardware dials. Especially the Nuimo is great!
I sold my Ortho and never looked back.
