4.1.22 SOFTWARE DOWNLOAD (FUNCTION 12)
Instead of replacing an EPROM to update the machine’s software, use this
procedure to update the software in the Flash ROM.
This function copies software from an external medium to the Flash ROM on the
FCU inside the machine. The external medium for the new software can be another
FCU or an EPROM board.
1. Turn off the machine.
2. Insert the Flash/SRAM Copy Tool into the IC card slot, then connect the FCU
or EPROM board with the new software as shown in the above diagram (the
EPROM board is shown here).
NOTE:
The switch on the tool must be at the
ON
position.
