Hardware Support: RailDriver Throttle

JMRI support for RailDriver is evolving rapidly, so check back here or on the JMRI users Yahoo group for changes.

Supported Hardware

JMRI allows you to use a RailDriver from PI Engineering as a Hardware Throttle to run Locomotives with your DCC system. RailDriver support was first available in JMRI 2.1.7.



First, connect your computer to your DCC system and make sure that the regular JMRI Throttles are working fine (Unless you do this first, debugging possible problems connecting the RailDriver is very difficult.)

Next, plug the RailDriver into a USB port on your computer while your JMRI application (PanelPro or DecoderPro) isn't running.


Once connected, start the JMRI program and select "RailDriver Throttle" from the Debug menu (It's temporarily located there while we develop the support).

A Throttle window titled "RailDriver" should open:

Type the DCC address of your Locomotive into the address box, just like a regular JMRI Throttle, and click "Set". This connects both the Throttle window and the RailDriver console through the DCC system to the decoder. You should now be able to operate the Locomotive from the RailDriver.

Raildriver Tools

Eventually, we'd like to make a more detailed simulation available by connecting the rest of the controls, and adding a detailed model of the trains braking and acceleration.
