[CA] No communication E7 and instruments

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Glenda,

It appears that at least the e7 MFD and possibly the Wind instrument may now have communications circuitry failures. Should an Evolution autopilot be installed onboard, then we may be able to use the diagnostics feature of the p70 autopilot control head to poll the SeaTalkng / NMEA 2000 backbone to list any SeaTalkng / NMEA 2000 devices sensed (MENU->SET-UP->DIAGNOSTICS->ABOUT SYSTEM). I two or more devices are listed, then any devices listed would then be deemed to have operational SeaTalkng / NMEA 2000 communications interfaces. Any devices not listed would then be deemed to have suffered a failure of their SeaTalkng / NMEA 2000 communications circuitry and should be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
