I have a couple microstep drivers that I acquired surplus. model numbers 31234 and 30737. They look like very step drivers from leadshine and others and the silkscreen on the case is identical but these have a 10 pin connector instead of the screw terminals for the P+/- D+/- and Ena+/- I'd like to use these drivers in another project but it's confusing which physical pins correspond to the markings. I've searched Tormach's site and it just says these are obsolete and replaced with other models but there's no datasheet detailing the pin assignment.

How can I tell which pins correspond to the markings?
