It is recommended to check the web site periodically for updates. To upgrade the DAC01 firmware, download the following from the RL website.

  1. The DAC01 latest firmware file (.RUF extension file)
  2. Racelogic Upgrader software

Connect the RS232 (port 3) of the DAC01 to the PC via the supplied RLCAB001 serial cable, and apply power to the DAC01.


Double click on the .RUF upgrade file, which auto runs the Upgrader software. Ensure the correct COM port is selected in Racelogic Update software, then hit ‘upgrade' to start the procedure.

When this is complete, powering the DAC01 off and back on will complete the process.


Note: To confirm which COM port is assigned to the DAC01, check device manager.

Ensure that other software which may try and use the COM port communications, such as VBOX Tools, is closed.
