D-sub cables shipped with Fusion are color coded according to the following table.
These D-Sub cables are marked with "Art.-Nr 1420531". DO NOT use the color
coding if the cable is not marked accordingly. Use a continuity tester instead
to determine the assignment.

Yellow Pin 2: TX, Fusion sends (RS-232)
Green Pin 3: RX, Fusion receives (RS-232)
Brown Pin 4: Do not connect

Audio Out

PowerFLARM Fusion emits an intermittent 1 kHz waveform on Audio Out (Pin 1 on
the D-sub connector) whenever a collision warning is issued. The frequency of the
beep depends on the time to collision. In addition, a test beep is emitted during
power-up if Audio out has been activated in the configuration.
Many FLARM Compatible displays have their own audio warnings. Audio Out only
needs to be connected when the audio warning of the connected FLARM
Compatible display is absent or not loud enough in loud cockpit environments.
Note: Audio Out is configured OFF by default. If connected, it must be enabled
during configuration.
