Hi Bill
My Mistake Bill, These are DB25 connectors and they are stepper drives
Unfortunately , no manual is available... even from the manufacturer..
they sent me a few pages of info that they had... but not everything
I need to know.
By having 3 parallel ports on my computer, would I be able to hook
them up or is there a better way?
Thanks,
Daniel
