JMRI Hardware Guide: Wangrow System One

Supported Hardware


Some Wangrow command stations have an "optional analog control circuit". In these, pins 5, 6, and 9 are used with an analog voltage as a separate throttle. If you have one of these command stations, a normal 9-pin serial cable will not work! You'll need to make a custom cable that just connects the "send data", "receive data" and "ground" pins. See your Wangrow manual for details.


  1. To connect your computer to a Wangrow system, you can usually just connect the command station to the computer's serial port using a 9-pin serial cable.

  2. Then go to the preferences panel of a JMRI-based program. This opens automatically the first time a program is run, or you can select it from the "Edit" menu.

  3. Select "Wangrow" from the top selection box. You can then select the proper serial port in the second selection box.

  4. The baud rate selection box will be fixed at 9600 baud.

  5. The series of radio buttons labelled "GUI style" allows you to select how the program will look. "Metal" is the native Java look available on all types. Other choices will vary with your computer type. "Motif", "Windows", "MacOS" and "MacOS Adaptive" look native on Linux, Windows, MacOS "Classic" and Mac OS X respectively.

  6. In the bottom selection box, you can pick the default programmer format. You can override this each time you open the programmer, so this is here just for convenience.

  7. Click "Save". You'll be asked if it's OK for the program to quit, click "Yes".

  8. Restart the program. You should be up and running.
