R701 stepper driver +Arduino

Using Arduino Motors, Mechanics, Power and CNC

Has anyone try to use this stepper driver with an Arduino?

I just read the manual and I think that it is easy to drive through simple code for steppers (with a library like Stepper.h for example). Is that correct?

Here is the manual: (http://edge.rit.edu/content/P10503/public/R701-manual_v6_28.pdf)

Looks a pretty standard step+direction based controller... should be OK but it doesn't actually say how much current the inputs take - hopefully less than 40mA (probably 20mA or so - opto-isolators are usually around this level).
