JMRI: Hardware Support

JMRI supports a wide range of DCC "command station"-style products from various model railroad automation vendors. We also support non-DCC layout accessories and devices that connect via a variety of networks and protocols. This page lists hardware and networks that JMRI is known to work with, and provides links to information on how to configure JMRI to work with each particular type.

If there is a way to make a computer communicate with a given piece of model railroad equipment, it is possible to connect it to JMRI. If you don't see your particular system here, please ask about it on the JMRI users.

For developers adding new hardware integration: see here for information about Creating Help and Web Pages for New Hardware.

General hardware info

Turnout feedback

If your layout uses some feedback mechanism to sense the actual positions of Turnouts, for example a microswitch connected to the throw bars or a decoder that returns a confirmation message, JMRI can use that to keep track of what's actually happening on the layout. We call this "Feedback", and how to configure and use it is described on the Turnout Feedback page.

PDA [Deprecated]

A way to use a PDA to access JMRI.
