SantaFeFan posted:Unfortunately, the DZ-2500 is not compatible with the STM2. I have talked to Dennis at Z-Stuff, and Lionel is reviewing the options to support the DZ-2500 in the future.
The DZ-1000 may work, however we have not tested this controller and are unable to give guidance at this time.
If you use the DZ 1008A relay modules, you could put +5 vdc on the NC contacts and -5 vdc on the NO contacts. Then the C terminal would behave just as the RSC terminal yellow wire from the Fastrack switches and would be wired to the 16 inputs of the STM2. The 5 volt power supplies using isolated wall warts are quite available from many sources and you would only need one of each to supply the + and - 5 vdc to many DZ 1008A relay modules. There is almost no current requirement for the inputs of the STM2.
