Each "FF" represents a blank 32k bank of memory. The bar in the top right hand corner spins to show
communications are continuing, and the bar on each bank in turn spins first clockwise as information is
loaded from the PC, then anticlockwise as the bank is programmed. When each bank is complete it shows
either a tick "
" when complete, a "-" if it is intentionally left empty, or an "X" if it fails to program. Any failure
/
to program is automatically retried, and an "X" should never reman on the screen.
Whilst the programming continues the PC report the status as messages are transferred, and displays the
percentage of the file that has been transferred. When the programming is complete, the unit prompts the
operator as follows, and the PC returns to the DOS prompt:
At this point the processor re-boots. The first reboot with a new main code the unit performs a checksum
test on each bank, displaying the results as follows:
Finally, when the checksums are verified, the processor jumps into the new Flash code, and begins
execution of the latest version of the embedded M&C code. Should the code fail to execute properly, hold
down the No/Prev key to clear the memory.
Should the program ever crash, or be otherwise reset (other than from power up), it will automatically do
an extensive checksum test as above. However from a normal power up, where it may be critical to restore
the service as quickly as possible only an abbreviated test is performed, and the screen above will not be
displayed.
