Need help with cv/ccw - dir/step conversion

[color 65]

Hello to all,
I have an old Vexta stepper driver with negative ground and CW/CCW inputs. Most of the breakout boards have only STEP/DIR outputs and I will be very happy if somebody post the circuit diagram for this conversion. Thanks in advance.
