CAN Bus Interface
These terminals provide communication using the SAE J1939 protocol and provide high-speed
communication between the Analog Expansion Module and the DECS-250. Connections between the
AEM-2020 and DECS-250 should be made with twisted-pair, shielded cable. CAN Bus interface terminals
are listed in Table 32-3. Refer to Figure 32-9 and Figure 32-10.
