Wiring Driver to Acorn

I have been converting an INDUSTRIAL CNC Router. I have changed out the original drivers and am wanting to use the drivers that are specifically specified for the stepper motors that came with the router. I have the new drivers but the wiring diagram does not make sense to me. It is creating a common +5 VDC and connecting the - direction and - pulse to the ACORN. If someone can look at the attached picture or webpage and tell me how to wire it that would be great. I am attaching a PNG of the wiring diagram that I found at this website.

The wiring shown in that diagram is the same as our schematic S14976. The 5V comes from a power supply (i.e. 5V output of Acorn power supply) and the DIR- and PUL- go to the corresponding terminals on the DB25 header.
