Updating CAN Nodes
via the Envizio Pro or
Envizio Pro II
Envizio Pro and Envizio Pro II with version 2.2 or higher software are capable of programming nodes on the
CANbus directly through the field computer and connected cabling using a USB flash drive with the CAN
Update program.
Note:
Before trying to update a CAN node, make sure the node is communicating properly over the
CANbus. If the node is not communicating properly, the field computer will be unable to update the
node.
Node updates are available by contacting the Raven customer support center at 1-800-243-5435.
Note:
Create a folder labeled “canupload” on the root of a USB flash drive (i.e. “G:\canupload” and place
the necessary .hex files within this folder.
To Update CAN Nodes
Important:
DO NOT remove power or unplug any cabling connections during the node update process. If the update
process fails to complete the update successfully, the node may become unresponsive. Unresponsive
nodes will need to be returned to Raven for repairs.
1.
Start the field computer and touch the Information icon in the upper, right corner of the Home screen.
2.
Touch the icon on the About Envizio Pro screen to display the CAN Diagnostics screen.
3.
Insert the USB flash drive with the required .hex files into an available USB port on the field computer.
NOTICE
Updating a CAN node erases the current
settings in the node. To retain settings and
calibration data, be sure to write down all
settings stored by the node(s) being updated.
