Encryption Key Restoration
How to restore the old encryption key to the machine
The following message appears after the controller board (PCB15) is replaced. In such a case, it is
necessary to restore the encryption key to the new controller board (PCB15).
To do this, follow the procedure below.
Prepare an SD card that has been initialized in FAT16 format.
1.
Using a PC, create a folder in the SD card and name it "restore_key".
2.
Create a folder in the "restore_key" folder and name it the same as machine's serial number,
3.
"xxxxxxxxxxx" (11 digits).
Create a text file called "key_xxxxxxxxxxx.txt" and save it in the "xxxxxxxxxxx" folder. Write the
4.
encryption key in the text file.
/restore_key/xxxxxxxxxxx/key_xxxxxxxxxxx.txt
•
Ask an Administrator to enter the encryption key. The key has already been printed-out by
the user and may have been saved in the "key_xxxxxxxxxxx.txt" file. (The function of
back-up the encryption key to the SD card directly is provided 11A products or later.)
