I’ve been getting emails recently about updating the decoder definition files in DecoderPro, so let’s go over that. The first and easiest method is to simply go to the JMRI website (http://jmri.sourceforge.net) download and install the most recent version of JMRI. In the process all the most recent decoder definition files will be installed—voila. Remember though, make a copy of your database before you do an update, just in case. That’s the first way.
The second way is to download and install the most recent version of any decoder definition files you need. This is a multi-step process so get ready to take some notes. Go to the following site (http://jmri.org/xml/decoders/) and using your mouse right click on the name of the decoder file you want. In the options that pop up, select Download Linked File. The file will be downloaded to your computer. Next open DecoderPro and in the Files menu option select Import Decoder File and enter the location of the file you just downloaded. Be patient, it will take a while for it to complete the process and there isn’t any indication that it is doing anything at all.
The third method is easier, I promise. Just like in the second method, go to the JMRI website and click the file you want. Next copy the url of that particular file from the window at the top of your browser. Now go back to DecoderPro and the Files option. Select Import Decoder URL. The program will then download the file and install it. If the file doesn’t appear right away you may need to restart DecoderPro. And remember if you ever run into any questions there are excellent explanations of these steps and more on the DecoderPro website so take a few minutes and familiarize yourself with the details. I think you’ll find it comes in real handy on those nights when you can’t get to sleep any other way!
