AR-C170M ROM VERSION UP 12 - 2
C. Flash ROM version up method
(In the case of PCU ROM, ICU ROM, Operation control ROM, Scanner control ROM, FAX control ROM)
There are following two methods of Flash Rom version up.
1) By connecting a computer with the ICU PWB, the program
data of Flash ROM is written from the computer to the Flash
ROM on the ICU MAIN PWB.
ROM on the ICU MAIN PWB.
This method has the following two variations.
a) All data in the PWB programs and the Flash ROM copy
(ROM-ROM) program are written: (Making of the source
ROM)
ROM)
In this method, the Flash ROM on the writing side needs
capacity of 32Mbit x 2

(In order to make a source ROM, the capacity of the Flash
ROM must be as shown above.)

b) Only each PWB program is written.
2) Two Flash ROM sockets on the ICU MAIN PWB are used to
copy the program in the source ROM to another Flash ROM.
(It normally takes 30 to 60 sec.)

(Note)
To make version up of several Flash ROM's of several machines,
it is the most effective to make a source ROM by the method of 1)
-a) and copy the data to several Flash ROM's by the method of 2).
