4.6.1 Primary J1939 Data Link (CAN1)
The Primary J1939 Data Link is supported by all of the PowerWizard controls.
The Primary J1939 Data Link is used for local communication among modules associated with a single generating set. The
PowerWizard can interface with both Electronic Engines (EUI) and Mechanical Engines (MUI). In MUI engines, the engine
sensors are wired directly to the PowerWizard. The Primary J1939 Data Link utilizes the Society of Automotive Engineers (SAE)
J1939 protocol and requires hardware compliant to the high-speed Controller Area Network (CAN) 2.0B protocol dened in the
International Standards Organization (ISO) 11898-2 document, running at 250k bits per second.
The Primary J1939 Data Link supports appropriate SAE J1939 Broadcast Parameter Group Numbers (PGN) and Suspect Parameter
Numbers (SPN) for engine and generating set data and diagnostics.
