Identify a driver

[pearcecustoms]

Are there any ways to identify a driver? There are four of these on my router table and I am trying to integrate mach3 to these.

I have attached a link to a picture of the driver I am trying to ID, if anyone happens to recognize it.

I am really just trying to decipiher the pinouts on it. The four wires on the right are the inputs. The bottom four on the left are the outputs to the motor and the blue two above that are power. They stay steady at 2.51v.

Any help is greatly appreciated. Thanks

well I found some info. I assumed the data stamped on one of the processors was just a generic part number. It turns out that IMS is the company.

For future reference to anyone that might need the info, here is the PDF.

Now, down to trying to get this thing moving.
