Supported Hardware

Command Station

Lionel TMCC or Lionel Legacy thru the serial port on the Command Base.

Limitations

As of JMRI v 2.11.8, Lionel TMCC Train commands are not yet available.

There is no Lionel TMCC model under the DecoderPro Roster Entry tabs, but you can set up TMCC decoder equipped Locomotives using the NMRA standard decoder near the top of the list.

Connecting

Wiring

First, connect your computer's serial port to the TMCC command station using a serial cable. This should be a "straight-through" or "modem" cable, nota "crossover" or "null-modem" cable. if your computer doesn't have a built-in serial port, you can use a USB-serial adapter, but make sure you install the correct drivers if needed. Recent Mac OS distributions have the drivers already there for some adaptors.

Settings

Next, configure the program:

Features

(Not yet complete)

With JMRI 2.11.8, Lionel TMCC operation for engines and accessory decoders is available. Train commands are not yet available.

The functions below will take care of all Engine Controls on TMCC and the basic commands on Legacy. The Accessory and Route and Train ( multi Lash Ups ) are not implimented. The Switch commands should also work even if you are using CMRI to control the switches.

Listed are the common actions for Railsounds 4, ERR conversion boards, and TAS boards. Any Accessory that uses Engine ID commands will also work however the function buttons will have different meanings. Consult the manual that came with the Accessor ( Crane Car, etc. ) to determine what the aux 1 buttons do for that item and label the Function Burrons accordingly.

When using a JMRI Throttle to run a Locomotive, the function buttons are allocated as follows:
