What is SPROG II?

SPROG II is The programmer for all DCC decoder needs,and works with the powerful JMRI DecoderPro software to support programming of any DCC decoder, including sound.

SPROG II gives you the ability to program DCC decoders using your computer without the need to move your computer to the railway room, or your existing DCC system to the computer room.
SPROG II is complementary to your existing DCC system, and operates as a separate decoder reading/programming facility, with a dedicated section of track.

SPROG II is supported on a range of hardware platforms and operating systems by DecoderPro. The JMRI DecoderPro software gives you automated recognition of decoders, a comprehensive record of your complete roster, easy to use views of all settings, and full access to all Configuration Variables.

More than just a programmer

DecoderPro includes throttles for SPROG II allowing it to be used as a computer based command station/booster to test your decoder-equipped loco, or for small layouts with two or three locos in use at one time.

SPROG II is now available directly in the USA and UK, and through selected retailers.

The Decoder Programmer in a ready-to-run package! This complete package includes a powerful 1.25A power adapter (see below), USB cable and all software and installation instructions (Java runtime, DecoderPro, USB drivers) on CD-ROM.

Power Adapter

SPROG II runs from a regulated power supply, that powers the SPROG II and the track. For good results it is essential to use a well-regulated power supply, and these models have been selected to provide an economical yet high quality result.

We offer a suitable regulated "wall wart" 12v 1.25A supply, included with our SPROG II USB package, and also available separately for $17. This power unit is excellent for programming all Z, N or HO locomotives (and even larger scales!), even those current-hungry sound decoders!

Sound Decoder Update

No need for a separate programming booster when you use SPROG II!
SPROG II has been tested with Soundtraxx Tsunami, LokSound, MRC and QSI sound decoders and will program and read all CVs in operations mode (on the programming track), and also 'program on the main'.
