AR-C260/C260M  ROM VERSION UP  12 - 2

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.

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)

In this method, the Flash ROM on the writing side needs capac-
ity 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.) 

In this method, the Flash ROM (source ROM) made by the method
of using a computer and writing the program to the Flash ROM is
required.

(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).

AR-C260/C260M  ROM VERSION UP  12 - 4

(2)

Method of copying with two Flash ROM sockets on the ICU MAIN PWB
The program for each PWB in the Flash ROM (Source ROM) on the Read side Flash ROM socket is copied to a Flash ROM on the Write side
socket.

*1: This Flash ROM was made by writing the program data from PC to the ICU MAIN PWB Flash ROM.

NOTE: Besides this method of Flash ROM version up, there is another method by use of a machine of the AR-350/450 series.

This method, however, allows the version up work in a shorter time.
For details, refer to Technical Report ARE-352 (ARJ-390).

The desk unit control program is installed in the Flash ROM in the CPU
of the desk unit control PWB.

Therefore, this Flash ROM cannot be replaced physically.

The PC is connected with the desk unit control PWB, and the Flash
Rom program is written from the PC to the Flash Rom in the CPU.

When making version up of ROM, check the combination with the ver-
sion of ROM installed to the other PWB including options.

In some combination of ROM versions, the machine may not operate
normally.

If all the ROM's are of the latest versions, there is no problem.
