The other night I was trying to do some programming on DM&IR 413 and had the darndest time trying to get my PR3 to work and thought I’d post my solution incase it might help someone else.
The problem I was having was JMRI crashing when starting up if the PR3 was plugged in* and Model Railroad Automation (http://www.perecli.com/rrauto/) was giving errors about being unable to communicate with the Loconet. After wasting to much time troubleshooting I eventually got it resolved. I un-installed the device from the Device Manager to remove the driver from the driver cache. Then I plugged the device back in and re-initiated the driver install process. This was on a Windows 7 64-bit machine so if you see something similar this may help you.
In my opinion JMRI is kind of a pain to use, I like Model Railroad Automation but it doesn’t really do decoder profiles or any of the CV calculators or tools. As a replacement I’m working on my own app for this, I’m in the exploritory phase but if it goes well I’ll be sure to post updates to the blog.
*Really JMRI? You can’t just put up an error message if the PR3 isn’t working? It’s annoying enough that I have to open restart the app to change COM ports but you can’t do the simplest error handling?
