CANbus Interface
These terminals provide communication using the SAE J1939 protocol and provide high-speed
communication between the Analog Expansion Module and the DGC-2020. Connections between the
AEM-2020 and DGC-2020 should be made with twisted-pair, shielded cable. CANbus interface terminals
are listed in Table 10-3. Refer to Figure 10-5 and Figure 10-6.
