Can someone confirm the signal requirements for Mach3 MPG inputs to a parallel port? I haven't been able to find it anywhere.
It looks like there are two signals required as the setup shows A and B signals.
Is a quadrature signal required or something else?
I'm asking becasue I came across a nice handwheel on a panel with a bunch of switches. The handwheel may already produce a quadrature signal. If not I'll make my own circuit to generate whatever is required.

Sage,
Yes, you need a quadrature signal.

Thanks. I'll see what I can cobble together.
