Donate to JMRI.orgJMRI: 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.

- IPOCSMR
-
IPOCSMR is an Open Source Software implementation of an IP based
interface to control Model Railway objects such as points/switch
motors, lamps and detectors. IPOCSMR is designed using ESP8266 as
the Wi-Fi link to the object controllers and Arduino UNO to
realize the direct object control. IPOCS interfaces JMRI utilizing
MQTT and comprises of an interface software running in the JMRI
environment, an IP communication software running in an ESP8266
and an object control software running in Arduino. Additional
information, system descriptions and software can be found on
GitHub.
Configure: Connecting to a IPOCSMR system.

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.
