JMRI provides a range of tools that are optimized for specific purposes:
The following tools in the Tools menu work with most DCC hardware connections:
- JMRI calls just about any output to the layout a
"Turnout". The Turnout object has 2 states: Closed (On)
and Thrown (Off).
For outputs such as Lights and Signals JMRI provides special objects (see below).
- Lights are digital output bits that function as on/off switches. Lights were created to provide easy control for fascia panel lights and scenery lighting. Lights can also be used for any purpose that requires an on/off switch. A light can be used, for example, to activate an electromagnetic decoupler for a pre-determined time in response to a fascia panel button.
- A Sensor is JMRI's way of representing an input from the layout.
- You can open multiple software Throttles to run your DCC locomotives.
- JMRI provides tools for managing locomotive consists.
- Signal Heads and Signal Masts are how JMRI represents and controls signals on a layout. They are a specific kind of output device that can be set to various Appearances (Red, Yellow, Green, Flashing Yellow, etc.) or Aspects (Stop, Clear, Approach limited etc.) following prototype rules.
- Blocks are sections of track whose occupancy may be individually monitored in JMRI. Dividing your track into Blocks is optional. Block occupancy is indicated by the state of an occupancy Sensor.
- Reporters are JMRI's way of representing information reported back from the layout and can contain arbitrary information.
- A JMRI Memory Variable can hold any type of object specified by the user.
- Routes are a tool for driving multiple turnouts when something happens on the layout. You can have a panel switch through all the Turnouts in your yard throat, etc. They can also change the status of Sensors, play sound files, and invoke scripts. They have some simple logic capabilities for deciding when to set the Route's outputs.
- LRoutes extend the capabilities of Routes by implementing them as a Logix. LRoutes can be defined with an unlimited number of Sensors, Turnouts, Lights, and/or SignalHeads for actions or controls. LRoutes provide an easy starting point for creating new Logix since they may be extended to include any of the Logix capabilities.
- A Section is a group of one or more connected Blocks that may be allocated to a Train traveling in a given direction. Sections were created to solve the direction problem that can occur when using Blocks directly.
- A Transit is a group of two or more connected
describes a route around the layout of a Train traveling in a
given direction. A Section may be in multiple Transits,
and may be in a given Transit multiple times.
Transits and Sections are essential to Dispatcher
- A Logix is a tool for entering powerful logical expressions that can control parts of a layout. Each one can monitor multiple inputs and logical operations through containing a number of Conditional expressions, each of which can take simple actions. For more powerful control, combine the logical reasoning of a Logix with the powerful output controls of a Route.
- JMRI can both provide various types of Fast Clocks on the computer screen, and also work with the fast clocks already installed on your DCC layout.
- A tool for determining the scale speed of your locomotives. You can use this while setting them up, to catch speeders, to match the running speeds of two locomotives before running them in a consist or for whatever you'd like.
- JMRI audio objects hold information about sounds that can be played-back by the computer.
- The Dispatcher tool provides functions and organizes information relating to dispatching trains on a model railroad layout. Its main function is the allocation of sections of track to various Trains running around the layout. This set of tools has evolved into a full DispatcherPro application.
- The Operations tool has evolved to an advanced OperationsPro application, allowing you to generate Trains and produce computer generated Manifests and Switch Lists for your railroad from a roster of rolling stock, schedules and destinations. This set of tools has evolved into a full OperationsPro application.
