Updating Firmware Issues
NOTE:
Use KMC software to update firmware
over the network
for
versions of KMC software that support
the FlexStat.
Finding and Selection Issues
• To view and download
firmware updates
from
FlexStat product pages on the KMC Controls
web site, you must log in with a valid user
name and password.
•
Use firmware designated for over-the-
network updates
. Firmware meant for the
HTO-1104 Firmware Upgrade Kit will not work
over the network.
•
Ensure firmware for the correct model is
selected
. If firmware for the wrong model
is accidentally installed, the outputs will not
match the applications/configuration on the
display.
NOTE: Backing up
the existing settings and
firmware image
before or during the
upgrade process
is recommended
practice.
Malfunction after Firmware Update
• Restart the FlexStat.
•
Check the application configuration.
NOTE:
Restoring to the factory defaults and
reconfiguring might be needed if how
