EV1 FAILING

Ian,

Q1: No sure i fully understand the MFD connections bit. Presently i have two things that need connection to the backbone via STNG convertor, the E120 and a S100 remote for the pilot.
A1: The E-Series Classic MFD will not be connected to the SeaTalk bus (i.e. its SeaTalk/Alarm Cable will not be used unless you desire to interface an external alarm to the MFD. The MFD's SeaTalk2/NMEA 2000 port will instead be interfaced as a spur to the powered and properly terminated SeaTalkng backbone which includes the SeaTalk to SeaTalkng Converter. The wireless autopilot base station will be interfaced to the yellow SeaTalk port of the SeaTalk to SeaTalkng Converter.

Q2: I am not running any 0183 wiring and don't intend to do so. Does this setup preclude the display of AIS on the E120?
A2: As indicated within the previous response, the E-Series MFDs will only process AIS data received via the MFD's NMEA 0183 port. As such, should you not interface the MFD to the Ray70 via NMEA 0183, then the MFD will be unable to display AIS target data.
