otakar_g Is it possible to have two focusers connected to same ASIAIR at the same time ?
Yes, it is.
You cannot control them simultaneously, but you can switch between any number of EAF that are connected to the ASIAIR USB bus by selecting any one of them in the Focuser Setting window, and controlling one of them that way.
However, you will need to do something to be able to distinguish between the different EAFs. If you don't do anything, all the focusers from the factory will appear in the Focuser Settings menu as "EAF".
To change the name, you will need a program like one of the programs in the ASIStudio suite. In the focuser control windows of the ASIStudio programs, there is an "edit" icon that allows you to append to the name of a particular EAF. E.g., if you append "guide" to the name, the EAF will be seen as "EAF (guide)" in the ASIAIR Focuser settings menu.
The UI is a bit cumbersome since there is only one focuser control in ASIAIR. You, the user, have to keep track with which focuser is selected -- the only place you can find out which one is selected is in the Focuser Setting window, although by judiciously choosing the "current" EAF position, you can use that as a hint which EAF is currently selected.
