8-2 Updating the RAC Firmware with SUSI
Firmware files issued by Sperry Marine will usually be named such that
the filename identifies the device type and the firmware revision. The
file extension used for firmware files is “.upd”.
To update the Rudder Angle Calibrator firmware:
1. If the RAC is currently powered up, switch off the power first.
2. Open the RAC housing and locate the USB service port receptacle,
J3, on the PCB. Make sure that the port is freely accessible for plug-
ging and unplugging the USB cable.
3. At the PC, start up the SUSI application.
A login dialog pops up:
4. You may either:
– Enter the PIN “ 20097 ”.
This will start up SUSI in the service mode.
Or:
– Leave the PIN empty.
This will start up SUSI in the “unknown login” mode.
In this mode, you may update the RAC firmware, but will not be
able to access the RAC’s configuration parameters without quit-
ting and restarting SUSI in the service mode.
Click to continue.
5. SUSI’s main window now opens, with the “Application” tab display-
ing a list of supported devices:
6. Plug in the USB cable at the PC and at the RAC’s service port.
