3.9 COMMUNICATION PORT USAGE
3.9.1 CAN INTERFACE
Modules are fitted with the CAN interface as standard and are capable of
receiving engine data from engine CAN controllers compliant with the
CAN standard.
CAN enabled engine controllers monitor the engine’s operating
parameters such as engine speed, oil pressure, engine temperature
(among others) in order to closely monitor and control the engine. The industry standard
communications interface (CAN) transports data gathered by the engine controller interface. This
allows generator controllers to access these engine parameters with no physical connection to the
sensor device.
NOTE:- For further details for connections to CAN enabled engines and the functions
available with each engine type, refer to the manual Electronic Engines and DSE Wiring.
