- SPROG IIv4 DCC Decoder Programmer
- USB A to USB B cable
The SPROG IIv4 DCC Decoder Programmer is the perfect tool for programming and testing DCC locomotives! The SPROG IIv4 is able to run a small sized layout, perfect for those who may want to have a small test layout at home or in the office. Simply connect the SPROG IIv4 to a 12-15V DC power supply capable of supplying at least 1A (1.25A recommended) and connect the supplied USB cable to your computer running JMRI Decoder Pro (free download).
The SPROG IIv4 is the latest version of the original SPROG design, and is compatible with all major brands of decoder, including sound decoders. Note if you would like to program larger scale decoders, or decoders that require more than 15V for successful programming, consider purchasing the more powerful SPROG III. If you would also like to operate more than approx. 4 locomotives at a time on a small to medium sized layout, consider the SPROG III instead.
