SPROGIIIntroductionSPROG II and SPROG 3 are stand-alone computer controlled programmers and controllers, complementary to your existing DCC system. They are not interfaces to any particular DCC system.The SPROG family gives you the ability to program DCC decoders using your computer without the need to move your computer to the railway room, or move your existing DCC system to the computer room. Commands from the computer's USB port are formatted into DCC packets for programming of decoders or operating small layouts or DCC accessory systems.No additional hardware is required for programming sound decoders, but note that only the DCC CVs may be programmed. The SPROG is not able to download new sound files to sound decoders.SPROG II is the original DCC Decoder Programmer, available now for over 7 years and sold worldwide through our network of distributors and dealers. SPROG II can also be used for test running locos after programming or controlling a smalll layout with its integrated 1 Amp booster.Download the SPROG II User Guide hereSPROG 3 is the new generation SPROG with a more powerful 2.5 Amp boosterDownload the SPROG 3 User Guide hereSoftwareThe SPROG family is supported on a range of hardware platforms and operating systems by a number of software packages.Not all software supports all platforms or all SPROG features, so please visit the web pages to confirm availability and support for you particular environment.DecoderPro (Programmer, Command Station, PC, MAC, Linux)TrainProgrammer_ (Programmer, PC)RocRail (Programmer, Command Station, PC, MAC, Linuxs
