On our current machine (the gantry plasma machine) we are using 7i42 buffer
cards with a 7i43 card and a custom firmware load from Mesa which has 4
step/dir and 4 single ended encoder inputs. We built a small board that
converts the differential signals from our encoders to single-ended inside the
electronics cabinet.
I also have a small mill on which I used the 7i43 with a 7i47 daughter board.
On that one I have three stepper motors (step/dir) and three differential
encoder signals wired to it.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
