Updating the Firmware
Whenever it is necessarry to upgrade the on-board software, the new firmware can be
downloaded using the serial port COM0.
If the on board boot key is pressed during at power up reset, an internal bootstrap-loader
is activated and waits for instructions from the serial port COM0. A loader program will
be shipped together with the file containing the image of the new firmware. The current
fimware is retained in the flash memory until the download program sends a command to
erase the flash. So if the boot sequence was initiated erroneously, the program memory is
not deleted accidently. The system is ready to go after the next power up.
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 pro-
posed by the manufacturer of the battery.
