Upgrade Menu

This menu is used to upgrade the software to a newer version. If a new version of the software is
available, an upgrade file will be posted on our web site. Save this file to a USB flash disk drive. It
needs to be the only upgrade file stored on the root directory of the stick. Press the Enter key to import
the software upgrade file from the stick to the controller.
The controller will display the progress of the file import process. If the file was successfully imported
from the USB disk the controller will display Transfer Success. The controller will automatically reboot
and come up with the new software installed.
Upgrade
To check that it was successful, turn off power to the controller, then press the Enter key while turning
power on. The controller will show the software version, which should match the name of the upgrade
file that you used.
