DG4S wiring common gnd vs common positive in controller

Hey, I'm wondering if there is any solution to connect DG4S to Ruida 6445 controller. The issue is that DG4S is having Step+ and Dir+ inputs with common grounds, and controller is having Step- and Dir- outputs with common positive.
Thanks,

Find the ground terminal for that +5V power output and use that.
However if your controller has NPN transistor output then you will also have to add one-one pullup resistors (Lets say 100 to 220 Ohms) from the outputs to the +5V terminal of your controller.

I solved the issue with 3rd party NPN to PNP converter and that worked fine.

Good to hear you got it resolved.
