AR-C170M  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).
(Desk control ROM)
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.
2. Precautions
A. Relationship between each ROM and version 
up
When making version up of ROM, check the combination with the
version of ROM installed to the other PWB including options.
In some combination of ROM versions, the machine may not oper-
ate normally.
If all the ROM's are of the latest versions, there is no problem.
