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 serial port COM0. There is no need
to remove the board to insert a new EPROM.
If both buttons Menu and Set in the front panel are pressed concurrently or the pin
'/BOOT' at the blade-connector strip is held at TTL-low level while the system is
powered up, a bootstrap-loader is actived and waits for instructions from the serial port
COM0. The new firmware can be sent to PZF600 from any standard PC with serial
interface. A loader program will be shipped together with the file containing the image of
the new firmware. The process is independently from the content of the program
memory, therefore it is possible to start this action again in case of a failure.
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.
