Today at work we found some Ecostep 200 controllers and Nema 23 motors made by Jenaer Antriebstechnik GmbH . We hooked one up and it seem's to function. But the real question is what do I use to operate the controller. You have to send the information via RS232 to the port on the controller to be able to make use of it. So how would I go about finding the correct software/hardware?
