Thanks for the quick reply. It answered my questions for testing.

Probing protected mode is a function where IF you are moving and NOT in G31 mode the machine will STOP if the probe hits an object to help protect the probe from damage. Sounds like you have it covered(;-)

Any update on the Ethernet Version?

The PMDX-422 is USB only. Our Ethernet capable product will be the PMDX-426.

The PMDX-426 is planned to support both USB and Ethernet. It will be similar to
our current PMDX-126, but with more I/O and will be more industrial in nature.

Our current plans target release in February with a price lower than the
combination of a PMDX-126 with a SmoothStepper.

Note: see this thread about the PMDX-426 future

Thanks for the info and the link. I just found out that the Galil cards are not supported in Mach4 yet.
And the Galil cards I own will not be supported.
And the Galil plugin will be a licensed pay product.

So I think it is time for a change.
