PMDX-122 vs PMDX-125?

I understand the issues of using the PMDX-132 vs the PMDX-122, but what about the PMDX-125?

The immediate and obvious issue is price, but are there others.

What features of the 125 do you really need for your application?

thats the real question as the -122 works and I can't really see that the newer -125 would be beneficial unless one was contemplating the SmoothStepper (which still has some issues).

A very basic principle of MechMate is to use tried and tested technology. The PMDX-125 is very new on the market (Maybe only 1 month?).

The PMDX-125 is double the price of the PMDX-122.

By which time there may be other products that are more USB (and proximity switch) friendly.

I would love to see a PMDX-product that is:
- USB
- Mach or Linux(EMC) compatible
- Mains 230 or 115V
- capable of stringing proximity switches in series
- capable of all the standard BOB functions we already have (E-stop, charge pump, couple of relays, etc.)
- small, but not tiny.
- fitted with pluggable connections for quick board swops.
. . . . . I still think that way

The only thing that "might" be of interest would be that the -125 has isolation (on some functions/pins).

I agree on letting someone else be the guinea pig (or in our case crash-test-dummy)
