CAN Acquisition tab
The CAN Acquisition tab is where incoming CAN signals are defined. These signals can be viewed in real time
along with the RT’s native data using NAVdisplay, or later using NAVgraph.
Note: A CAN isolator must be used when connecting the RT directly to a vehicle’s CAN bus.
Channels are added to the acquisition list by clicking on the ‘Load DBC file’ button and selecting a valid CAN
DBC file. The top 12 messages in the list acquisition list are logged at the INS update speed of 100 Hz or 250
Hz. This is not adjustable.
The Message name, Signal name and Units can be edited in the CAN Signal Properties window (Figure 30). This
is opened by double-clicking any signal. Changes made using NAVconfig are independent of the DBC file and
will not affect it or be saved.
