SPROG II: DCC programmer and Command Station for under $100! SPROG II is The programmer for all DCC decoder needs, and works with the powerful JMRI DecoderPro software to support configuration programming of any DCC decoder, including sound decoders. 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 an on-screen throttle for SPROG II allowing it to be used as a computer based command station/booster to test your decoder-equipped loco and check the programming. Also, use SPROG II as the complete controller for smaller layouts, with three or four locos in use at one time, from the on-screen throttles, or automate with PanelPro with an on-screen layout view.
