Ed,
The manual for the soft set technology specifies it to use in the Mini Commander series. Although it is not specifically in the manual for the Mini-2 it does work. I have used soft set on a number of my Mini-2 installations, the one in particular is the Doodlebug that I purchased at S Fest, and had discussed with you previously. I did not want to cut a hole in the chassis of the Doodlebug for the switch. I also used soft set on the Milwaukee Rd. RS 3 that I acquired from one of our club members in Milwaukee. We had also used the soft set method for programming on an American Hi-Rail Zephyr that belongs to one of our Badgerland members. You do not have to believe what I am stating here, but you might want to try it on one of the Mini-2 boards on your test set up. It does work on these motor drivers.
