  • Connect the RTD to your computer and open RTD Flasher.
  • From the Help menu, select Resync Interface.
    If you have issues syncing the RTD with your computer, install the drivers manually. The drivers can be found HERE or on the USB memory stick provided with the RTD, using the file named "CDM21228_Setup".
