4.2 PROGRAM DOWNLOAD
4.2.1 OVERVIEW
Here are some important points to keep in mind when downloading software:
• If an error interrupts download processing, the machine cannot operate normally
with the program software only partially downloaded.
• When download processing execution starts, "Downloading..." is displayed and
when downloading has completed successfully, the message is cleared.
• If the download is interrupted when the "Downloading ..." message is displayed,
the machine does not attempt a re-try.
• The program that downloads firmware from an IC card is part of the GW
controller software. If downloading this software is interrupted, the program
stored in the machine may be corrupted. Because of this, it may not be possible
to restart the downloading program. (In addition, if the GW controller software
cannot be downloaded, other software on other IC cards cannot be downloaded.)
However, it may be possible to restart the program without replacing the board
by setting DIP SW 1 on the controller to ON, and re-starting.
