About DecoderPro

DecoderPro is one part of the JMRI software suite. It is free to download and use under a GNU General Public License. It works on most computers and operating systems as well as with most DCC systems. Connect your computer to the Command Station using the appropriate hardware interface and program your decoders without knowing any CVs. It will also keep a record of all your decoder settings.
