Note: All screen shots in this manual are from a Windows machine using the "Metal" User Interface option . While your screens will probably differ in some layout details, they will be essentially the same. All programming examples shown are with Digitrax PR3(MS100 mode) connected to Digitrax Super Chief Radio Command Station. Most of the decoders in locomotive samples will be Digitrax, except for sound examples.

Note: This entire manual has been updated to correspond to JMRI® 2.14 DecoderPro3® only, and the HTML verified using HTML4 and Cascading Style Sheets. If the formatting looks odd, you probably need to update your browser.
