If you are running RealDash on same computer with the game, see this post first:
[Localhost connections on Windows 10/11]( Localhost connections on Windows 10/11 - General / Bugs and troubleshooting - RealDash Forum)
- 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 UDP protocol’
- Address: REALDASH DEVICE IP or leave to 127.0.0.1 if RealDash is running on same machine with BeamNG.
- Port: Use same port as in RealDash connection settings (default is 4444)
- Uncheck ‘MotionSim enabled’ option, or use different port. Otherwise MotionSim packages will intervene with OutGauge data.
BeamNG Drive will start sending the telemetry data when the game starts.
