The procedure below outlines the procedure for IMU04 firmware upgrade, IMU03 firmware upgrade and YAW03 firmware upgrade.
It is recommended to check the web site periodically for updates. To upgrade the IMU / YAW firmware, download the following from the RL website:
Connect the IMU/YAW to the PC via the supplied RLCAB030-S serial cable, and apply power to the unit.
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 IMU/YAW unit off and back on will complete the process.
Note: To confirm which COM port is assigned to the unit, check device manager.
Ensure that other software which may try and use the COM port communications, such as VBOX Tools and VBOX Setup, is closed.
