Using JMRI® to Operate Trains

OperationsPro: Setting your Preferences

The current JMRI Preferences Help is here.

In either PanelPro or DecoderPro, in the main menu bar click on the Edit menu -> Preferences... (Windows) or click on Preferences... in the PanelPro application menu (OS X). This opens the Preferences panel (The panel may open automatically the first time you run JMRI®).

The Preferences panel is split into two panes: on the left side is a list of Preference groups that may be set. Clicking on one of the Tabs opens that set of Preference options in the right side pane where options may be checked or changed.
Note: Remember to click Save to finalize your settings and then re-start JMRI to have them take effect.

To a first time user the most important part to start with is the Connections Tab, where you describe how your computer will talk to the DCC Command Station. You may leave most of the other Tabs at their initial or "default" settings until you find a need to change things to suit your fancy.

The Preferences -> Connections pane provides access to the basic configuration information to connect your computer to your DCC system. You may either set up JMRI OperationsPro to work as a digital Switch List generator using a "Simulator" Connection Type, or take advantage of the full JMRI Suite by connecting JMRI® OperationsPro to your DCC layout to actually build and operate trains equipped with DCC decoders and follow them on your computer screen.

In the following example, the Connections Tab was selected:

Let's set up JMRI Preferences for the Connection with your Command Station. In this example we are using a Digitrax DCS100 Super Chief Command Station, (radio) interfaced to the computer via LocoNet, PR3 (in MS100 mode) and USB port. We keep our JMRI master roster on the System Drive.

A second drop-down list may include a selection if there are more than one possibility. possibilityDrop-down list to select the serial port to which your DCC interface is connected.
