Optional J1939 Interface
1.
The integrated J1939 interface makes it possible to connect the generator’s ECU to
a vehicle multiplexing system for monitoring, control and real time diagnostic
information. Everything available via the Command and Control Center, and more,
is available through the J1939 interface.
2. Multiplex developers who have worked with Smart Power Systems
®
will be able to
supply database information, and screen layouts to their OEM customers. Potential
display screens and available information can be seen in Figures 26 and 27, below.
For independent development please contact Smart Power Systems

3. Generator systems equipped with the J1939 interface have a three pin harness as
shown above in the interface drawing, Figure 11. The connector pinout can be
found in the electrical schematic in Figure 2, above. A 120 Ohm termination must
be added if the generator’s ECU is a single network node.
