Command Station



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.

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. Open the Connections tab in the Preferences of a JMRI-based program. This opens automatically the first time a program is run, or you can select it from the "Edit" menu.
  2. Select "Wangrow" from the System Manufacturer drop-down menu.
  3. Select a serial port in the System Connection drop-down.
  4. The baud rate selection box will be fixed at 9600 baud.
  5. Click "Save". You'll be asked if it's OK for the program to quit; click "Yes".
  6. Restart the program. You should be up and running.
