2.12 Upgrading the CPU Switch Smart's flash memory
The CPU Switch Smart SUN-MAC-PC uses flash memory technology which enables
the firmware code to be upgraded by the user. Upgrades are performed by
connecting a PC's serial port to the CPU Switch Smart's options port and running an
upgrade program on the PC. This upgrade program downloads the new firmware to
the CPU Switch Smart and checks that the data has been programmed correctly.
To perform a firmware upgrade on your CPU Switch Smart SUN-MAC-PC you will
need a suitable serial upgrade cable and an IBM PC compatible computer with an
RS232 serial port and an operating system that supports DOS. Upgrade cables may
be purchased from LINDY Electronics or may be made using the wiring specification
