FCU Arinc Interface Board

For A320 series FCUs 

The Cavoksim FCU Interface board is designed to connect an original A320 Flight control unit (FCU) to a PC flight simulation. It is compatible with X-Plane for Windows in combination with Flight Factor A320 Ultimate and ToLiss A319, A321 and A340-600. Additionally Prepar3D with Jeehell A320 FMGS is now also supported.

The board is designed for easy plug and play connections. Only basic technical knowledge is required.

It uses the Cavoksim QuickConnect Plug and Play system with custom connectors designed especially for the FCU. This means easy connection with the FCU using 2 flat cables. No complicated and error prone DIY wiring is necessary anymore. The FCU can easily be connected in minutes.

A special on-board 5V/400Hz AC circuit is provided to supply power to the annunciator LEDs. This ensures that the LEDs illuminate bright and evenly like in the real aircraft. The photo below shows a comparison with simple 5V DC supply powering the LEDs on the left and the Cavoksim board providing 400Hz AC power on the right side.

The software package currently includes support for the following simulator platforms and aircraft:

- X-Plane with aircraft FlightFactor A320 and ToLiss A319,A321 and A340-600

- NEW: Lockheed Martin Prepare3D with JeeHell A320 FMGS

The package also includes a powerful diagnostic tool that can be used to check the FCU for any defects without the need of a simulator. It provides functions to test all buttons and lights as well as reading and decoding the Arinc responses and outputs of the FCU.
