Welcome back to the Raymarine Forum ray18,

Please additionally note that the release of LightHouse 3 v3.11 is imminent and it would be recommended that any testing be held off until this software has been released and installed within the MFD.

It is not recommended that the engine system be interfaced to the MFD in the manner shown within your diagram ... engine systems should not be interfaced to a marine electronics backbone without an engine gateway bridging the engine system to the marine electronics backbone. Were a technician to visit the vessel, fault isolation would be initiated by using the MFD's diagnostics features list other devices which have been interfaced to the system's powered and properly terminated marine electronics NMEA 2000 backbone. Should no devices be detected, then a NMEA 2000 analyzer (ex. Actisense NGT-1 & free Actisense NMEA Reader PC software, etc.) would be interfaced to the marine electronics backbone. The technician would then use the analyzer to verify that data from the MFD as well as data from the engine system was present on the backbone. Engine data is an all or nothing affair. That said, while a PGN may feature several different engine data items, the list of which engine data items will be populated will vary based upon the engine make, model, and serial number (consult engine manufacturer for specifics). NMEA 2000 PGN 127489 Engine Parameters, Dynamic is the NMEA 2000 PGN in which engine hours is transmitted. Within MFDs running LightHouse 3 v3.10.71 and later software, NMEA 2000 PGNs may be monitored within the MFD's diagnostics features (HOME->SETTINGS->NETWORK->DIAGNOSTICS->NMEA DEVICES & MESSAGES->NMEA MESSAGES).

Should the NMEA 2000 analyzer indicate that PGN 127489 Engine Parameters is being populated with engine hours and the MFD is reporting dashes for engine hours, then please respond accordingly.
