Hi Ulrich, Is your system a scope with the motors controlled in AltAz by their own controllers, then connected to a PC? You are expecting the PC to sort out the conversion between Ra and DEc and Alt Az? The PC would also calculate the movement rates in Alt and Azm to get the scope to track the sky?
What you probably need is a program on the PC that can control your motors and also provide Ra and Dec to CdC - or any other application.
