Radio Isolation / Isolation Group
In many cases there is a requirement to “radio isolate” or segregate specific Gateways and monitors
from other Gateways and monitors sharing radio proximity. This is achieved by designating a specific
group of Gateway and monitors to an “Isolation Group” (2). Note that both the Gateway and nodes
must share the same radio isolation group for successful communication. Modification of radio
isolation groups should only be done with guidance from Hubbell.
Node Firmware Update
The Node Firmware Update feature allows the Gateway to wirelessly broadcast firmware updates to
all monitoring nodes communicating with a given Gateway. This is an inherently safe feature since
firmware is transmitted redundantly over time and is not actually deployed until a complete image has
been received and verified to be correct. Due to the variability of the radio connections and network
load, firmware updates may take from a few hours to a day, depending on the size of the network.
During the update process the monitors will continue to function normally. When completed, the
monitors will automatically reboot and switch to new firmware.
Note that different monitoring node types use different firmware images. In a firmware version
designation the first number (e.g. "5" in 5.28) denotes node type and the second number (i.e. "28")
denotes the firmware version. Nodes of a given type will only receive firmware images of the
matching type. If multiple firmware images need to be upgraded (e.g. upgrading 5.28 to 5.29 and
23.12 to 23.14), upgrades have to be done sequentially (initiate one upgrade, wait for it to complete,
then initiate the next upgrade).
Updating firmware on monitoring nodes:
1.
Select the appropriate firmware version from the “Firmware” drop down menu (1). A list of
firmware updates can be found
here .
2.
Click the “Start Broadcast” button (2)
