7 segment hardware for X-plane

The SimulConn I/O-7s board is acting as an interface between your 7 segment display outputs and the X-plane flight simulator.

7 segment connections

The board is using the following connections:
– ribbon cable connection to the Extension board (AWG28 14-way)
– 8 x ribbon cable connections to the 7 segment displays (AWG28 16-way)

The board is powered from the Extension board via the cable and has a voltage regulator, maintaining the incoming current at 5v.

SimVim 7 segment configuration

The hardware in the example above is fairly easy to configure. The data.cfg file looks like this:

N2.2 D=0

N2.2	HSI_Course

And in the web configurator, its done like this:

  • Click the Master board pin that the I/O Input board is connected to.
  • Click “Add MUX for 7-Segment”.
  • Click the mux you added above and click the number relevant for the connector on the I/O-7s board.
  • Click “Connect 7-Segment Direct”.
  • Select “MAX7219” and click “Confirm”.
  • Click the display you want to connect in X-plane, and select “7-segment display”.
  • Click the mux you created, the connector you are using, and click “New entry”, and click “Done”.
  • Click “SAVE” and put the file in the SimVim folder in X-plane.

In this example, I connected the board to the Master board pin 2. Your pin number will change according to your setup.
