The Ruscool LCD Compass connects via a USB cable and will continually scroll as the Flight Simulator compass moves. 

The Compass is provided with software that has been designed to work with FSUIPC or X-Plane, along with detailed information on how to communicate directly with the LCD Display via the serial port.

There is a separate X-Plane version that can be purchased, which communicates directly with a plugin that will be supplied.  So please ensure the correct version is selected when placing an order.
