Updating the RAC Firmware with SUSI 8-3
7. Power up the RAC.
The “Online” button should now become clickable (not greyed-out),
indicating that SUSI has found a device to connect to:
The LED icon next to the button will remain grey, as no connection
has been made yet.
8. Click to connect to the RAC.
The LED icon should now change to orange and the status line
should read “Connected with RAC Bootloader”.
Upon connecting, SUSI opens the update tab:
The update tab provides file browsers to select firmware update files
for the Rudder Angle Calibrator’s system software (“MCU-Applica-
tion”) and the RAC’s bootloader (“MCU-Bootloader”).
The option to update program code for an FPGA (“FPGA-Applica-
tion“) is greyed out, as the RAC does not contain an FPGA.
9. Depending on whether you intend to update the RAC’s MCU boot-
loader or its MCU application, click the respective button to
call up the file open dialog. Then, navigate to the firmware update
file, select it in the dialog and click .
