5.0 Upgrading Gateway Firmware
Gateway Versions 3.0.0.0 and above are remotely
upgradeable. To upgrade the SMG, you will need to
already have or download the Monnit MODBUS Sensor
Gateway software executable and possess a Monnit Serial
MODBUS Gateway to USB Programming dongle. Once
these are in place, obtain and the latest file upgrade from
Monnit Support and save the file locally on your PC.
Put the SMG in bootloader mode by opening the enclosure
and accessing the RESET Jumper. Place the jumper over
the pins and remove and replace at least 5 times.
When the jumper is placed on the RESET terminals for the
first time, the middle light will flash red while the other
lights are off. Removing and replacing the jumper twice will
then cause the all three lights to flash on and off quickly in
red. Removing and replacing the jumper four more times
will cause the top Gateway light to go solid red, while the
other lights are off. Removing the jumper for the final time
will cause all three lights to illuminate solid red. Your SMG
is now in bootloader mode.
Use the Monnit MODBUS Sensor Gateway software and
find the menu “Gateway Commands”. At the bottom, select
the option “Upgrade Gateway Firmware”. Select the
upgrade file and click on “Open”.
While the code loads, the status is displayed in the bottom
left of the Monnit MODBUS Sensor Gateway Software.
The lights on the SMG will flash red and off during the
process. Upon successful upgrade, the SMG will then
reboot. Note that all registered sensors will be eliminated
and the new firmware will be in a fresh from factory state.
If an error occurs during the process, factory reset the
gateway using the jumper and try again.
