Note: If the Imager locks up or loses power during the
upgrade, it could corrupt the firmware, preventing the
imager from booting up normally.  If this occurs, you can
"rescue" the firmware using the following procedure:
• Rename the firmware file on the USB device to emup-

• Power off the imager (both switches) and insert the USB

• Power on the imager
• The Imager will boot up into emergency update mode.

• Power off the imager, and remove the USB device
• Reboot the imager, and go simulation 22-05 to confirm

FTP software is used to transfer the firmware data (extension “.sfu”) from the PC to the machine. The controller recognizes the firmware identi-
fier and the machine automatically switches to firmware write mode. After the firmware is updated, the machine automatically resets.
