If you are running RealDash on same computer with the game, see this post first:
Localhost connections on Windows 10
- Connect device running RealDash into same local network where game is running.
- Verify that you are not blocking UDP traffic or ports on your network router.
- Start RealDash, go to the Garage and setup new connection to ‘Racing Simulator->BeamNG Drive’.
- Note the Port and IP address that is shown in RealDash connection settings.
- Start BeamNG.drive and go to Options->Other.
- Enable ‘OutGauge support’
- IP:
- Port: Use same port as in RealDash connection settings (default is 4444)
- Uncheck ‘MotionSim enabled’ option
BeamNG Drive will start sending the telemetry data when the game starts.
