How to set up Preferences

Back to Index

The current JMRI Preferences Help is here.

From the Edit menu in DecoderPro select Preferences. On Mac OS X choose Preferences... from the DecoderPro application menu. This window may open automatically the first time you run the program.

prefernces menu

As a first time user the most important information is the Connections screen where you describe how the computer will talk to the command station. Most of rest you can leave at the initial or "default" settings until you find a need to change things to suit your fancy.

Most importantly, you must click to finalize your settings and then re-start the program to have them take effect.

The Preferences window provides access to the basic configuration information to connect your computer to your DCC system. You will be using that system to actually program and operate trains equipped with DCC decoders. An important concept to keep in mind is that JMRI is nothing more than a very smart throttle. If you can do something with your throttle you can probably do it faster and easier with JMRI. However, if your system can't do what you want, either because your system is not connected properly (it's broken) or the system manufacturer did not incorporate that capability, then JMRI will not be able to do it either. In the latter case JMRI will probably give you an error message or have the command "greyed out" to help you identify why it can't accomplish your request.

The window is split into two panes, on the left side is a list of preference groups that may be set. Clicking on one of the items opens the options that may be set in the right side pane. No selection have been made

Preferences
