Hi Friends
I have a problem with a servo motor on a lathe. I am using Mach3 as a controller and controlling the servo with step and direction signals which are single ended. The problem is I need to give commands up to 420Khz where the servo driver only excepts signals up to 200Khz in single mode. In differential mode the servo drive will except up to 500Khz which will solve my issue.

Long story short. How can I change my single ended step dir signals to differential A+ A- B+ B- signals. I have bought the recommended IC chip AM26LS31 and tried to follow the wiring diagram but have been unsuccessful with it. Does anyone have a drawing diagram, wiring schematic or suggestion on this.
Thanks
