DCC Decoder Manuals
Here's a selection of reference manuals for some of our favourite DCC decoders, and the ones we use when converting DC locos to DCC. These manuals are handy for looking up CV values, finding out how to factory reset them, and other functions. To identify your decoder manufacturer, read back CV8 and look up the value on JMRI's website.
The decoders listed below are all small enough to be suitable for N Gauge locos and DC retrofitting. For a full list, see our N Gauge DCC Decoder Recommendations page.
