The Digital Plus Decoder Programmer can both program decoders and upload new decoder firmware.
DCC features continue to evolve. One problem to date is that it that existing decoders cannot take advantage of these new features because they cannot have their firmware changed.
Starting with decoder version 7.0, all Digital plus by Lenz decoder are designed to be able to be re-programmed. The Digital plus Decoder Programmer is designed to update decoder firmware with the latest software release.
This firmware update can occur on the programming track even when the decoder is already installed in the locomotive!
The Digital plus decoder programmer can also be used as a full featured NMRA DCC CV programmer using the supplied computer applications.
