Troubleshooting

Common Issues

"PLT_CDU_LINE1" does not exist (CH-47 Chinook)

  • Wrong DCS-BIOS version. You need v0.11.5 or later.

"Connection failed" or CDU not responding

  • Ensure your WinCtrl CDU is properly connected
  • Try unplugging and reconnecting the device
  • Restart the application (it does not detect devices plugged in after start)
  • Check that no other application is using the CDU

"No data appearing on CDU"

  • Start your aircraft in DCS (data appears after aircraft systems are powered)
  • Check that DCS-BIOS is working — use Bort to verify
  • Verify Export.lua is configured correctly

Aircraft not detected / stuck on "Waiting for DCS…"

  • Make sure an aircraft is loaded in the cockpit and DCS-BIOS is exporting
  • Unsupported aircraft are shown in red — the bridge keeps waiting for a supported one
  • You do not need to restart when switching aircraft

Start bridge is greyed out

  • You probably launched the app before plugging your devices
  • Exit, plug all CDUs, then launch the app again

Brightness Issues

  • Mismatched brightness: Use the aircraft's brightness controls first, then adjust the MCDU
  • See each aircraft page for aircraft-specific brightness notes

Logs

All activity is logged to log.txt in the same folder as the executable.

Report issues on GitHub or on Discord.

Known Limitations

  • Cursor behavior: May appear erratic during waypoint entry (reflects DCS-BIOS data)
  • CH-47F support: Requires DCS-BIOS 0.11.5 or later
  • Brightness sync: May not perfectly match aircraft state
