Press any key to run
7. Pressing any key when using the system transfer tool will return you to the
main menu screen.
8. You can quit the system transfer mode and return to the RUN mode by si-
multaneously pressing any two of the four function keys on the panel of the
NT11. The same result is achieved when the NT11 receives a transfer end
instruction from the system transfer tool.
If any of the following events, or a system error, occurs during transfer of the
system program, the program will not be installed in the NT11 correctly.
• The power to the NT11 is switched off, or the NT11 is reset, during trans-
fer.
• The power to the personal computer that is running the system transfer
tool is switched off, or the personal computer is reset, during transfer.
• The cable connecting the personal computer running the system transfer
tool and the NT11 becomes disconnected or sustains a wire breakage
during transfer.
• Transfer is terminated by pressing any two of the function keys on the
panel of the NT11.
• Transfer is terminated by pressing the ESC key of the personal computer
running the system transfer tool.
In the event of any of the above, there is a possibility that the NT11 will not
operate or that unpredictable malfunctions will occur.
To prevent this, switch DIP switch SW2-6 ON to erase the system program
after the problem has occurred. For details on erasing the system program
with the DIP switch, refer to "Method for Erasing the System Program"
(page 68).
In order to erase the system program, the system program area must be
cleared. On shipment there is no data in the system program area and there-
fore the system program can be transferred without having to erase an exist-
ing system program first; however, if a system program already exists it must
be erased before the new one can be transferred.
The following is the procedure for erasing the system program.
1. Set DIP SW2-6 to the ON position and turn on the power or reset: the fol-
lowing screen will be displayed.
