What is PC Focus Control?

PC Focus Control (PCFC) replaces your focuser hand unit with precise motor control from the USB port of a Personal Computer (PC). You can use the free downloadable JMI Windows-based software or any ASCOM-compatible software. Testing shows that PCFC gives much greater control than a normal hand unit and JMI was able to get 0.0004" drawtube movement. There is no encoder feedback or positional display with PCFC. PC focus control with encoder feedback can be achieved with optional Smart Focus.

Product Questions

I have an older JMI motor focus for my 12" SCT and I was wondering if this unit, in place of the hand control, would allow for autofocusing using something like FocusMax for Maximdl? I'd hate to replace my entire focuser if this will work for autofocus.
