I Rewriting the Flash RoMs on system control Microprocessor and AÂy' control Microprocessor
l.
Preparation of the personal computer side
The "RS96" directory musr be copied to the "Desktop" directory of the PC that is used for rewriting, as an entire directory.
@Note: If the "RS96" directory is copied to any locations other than the "Desktop" directory, rewriting will not be performed.
2. Preparation of Files
When the "RS96" directory that was copied in step 1, is opened, the follow files appear:
rs96. exe
Serial command software
SortAV
Sort SYS
A file that creates the binary file of the A,/V control microprocessor
A file that creates the binary file ofthe system control mtcroprocessor
r rs96. log
Log frle of RS96
x Exe
The directory in which execution file is located
The files marked by the asterisk mark (x) are the hidden files that are not necessary to look at. They can be seen only when "all files display"
that is an option of the Explorer is set.
To rewrite the firmware via serial communication, the "mboof'binary file must be created from the "x*x. 1e1" file because the binary
file is used instead of the "**x. mot" S format file.
a. How to create the system control binary file
Drug and drop the ***. mot file of the version which you want to rewrite, to the SortSYS file'
b. How to create the A,/V control binary file
Drug and drop the *r<r< mor file of the version which you want to rewrite, to the SortAV file.
When the srep "a" or "b" is performed, the file named "mboot" is created. (The A/V and system controls have the same file name.) The
file name is set by default and the names other than "mboot" cannot be used.
3. Preparations at the Board Side
Connect the personal computer ("RSg6" is copied from the server) in which the mboot and the RS9t5. EXE are located in the same
directory as prepared in steps I and2,to the circuit board which you want to upgrade the version with a serial interface cable. Select
the
version upgrading mode.
Conditions to enter the version upgrading mode
While the OPEN switch: HIGH, the OPEN key: LOW, and the TEST mode: LOW, the DC-IN is applied (or system control reset).
In actual operation, open the shorting taps of the OPEN switch (this switch is normally open), shorts the shorting taps of the TEST mode
tap, and while pressing the OPEN key, connect the DC-IN power (or reset the system control microprocessor).
When the machine enrers the version upgrading mode, the POWER LED flashes to indicate that it is in the version upgrading mode.
