4.2.2 Data Alias Definitions
The names of data the sensor network produces and the WSDA can push onto the CAN bus are
defined below. All data is in big-endian format unless otherwise noted. Some data channels have
fixed sizes or depend on the node settings. Note: The Payload field of the Broadcast Message
Menu will also suggest values based on user-set configurations. To view the full list, select Payload
and hold while pressing the down arrow on the keyboard ( See CAN J1939 Output on page 22 ). For
Packet definitions and details on the data included in each packet, go to: Github.
