Firmware Upgrade Procedure
The firmware upgrade procedure is used to update the firmware embedded into the FASTRACK Supreme.
That procedure consists in downloading the firmware into internal memories through the RS232 serial link
available on the SUB-D 15-pin connector.
Refer to "Firmware upgrade procedure" [8] for a detailed description of this procedure.
