Firmware Updates
Whenever the on-board software must be upgraded or modified, the new firmware
can be downloaded to the internal flash memory via the board's serial port COM0.
There is no need to open the computer case and insert a new EPROM.
If the button behind a hole in the rear slot cover is pressed for approximately 2
seconds, a bootstrap loader is activated and waits for instructions from the serial port
COM0. A loader program shipped together with the file containing the image of the new
firmware sends the new firmware from one of the computer's serial interfaces to the serial
port COM0. The bootstrap loader does not depend on the contents of the flash memory,
so if the update procedure is interrupted, it can easily be repeated.
The contents of the program memory will not be modified until the loader program has
sent the command to erase the flash memory. So if the button has been pressed
accidentally, the system will be ready to operate again after the computer has been turned
off an the on again.
Replacing the Lithium Battery
The life time of the lithium battery on the board is at least 10 years. If the need arises
to replace the battery, the following should be noted:
ATTENTION!
Danger of explosion in case of inadequate replacement
of the lithium battery. Only identical batteries or batte-
ries recommended by the manufacturer must be used for
replacement. The waste battery must be disposed as
proposed by the manufacturer of the battery.
