Configure CAN network-level parameters
Platform: OEM729, OEM719, OEM7700
Use this command to configure the CAN J1939 network-level parameters (NAME, etc).
Issuing this command may initiate a CAN 'Address Claim' procedure. The status of the node and
address claim are reported in the J1939STATUS log (see page 112).
Once a "node" is configured using J1939CONFIG, and the "port" is configured to ON using
CANCONFIG "port" ON, J1939CONFIG "node" cannot be entered again until the "port" is con-
figured to "OFF" using CANCONFIG "port" OFF. (See the CANCONFIG command on page 16
