SProg II is a stand-alone computer interface that allows you to program decoders using JRMI Decoder Pro away from your Layout. You do not have to move the computer to the train room and you do not have to buy another DCC system. SPROG can program decoders, read decoders and switch to Ops mode to test run locomotives.
Decoder Pro is free software that allows supports programming of decoders in a more intuitive fashion than hand held throttles. One programmed, locomotive decoder settings can be stored in a roster of locomotives. If something happens to the locomotive programming, it can be restored by pulling up it's roster entry and sending the stored settings to the locomotive.
