EV1 FAILING

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum ifmdlvey,

It is recommended that you verify that the Evolution autopilot components (EV-1, ACU, and p70/p70R have been updated with the latest available Raymarine product software updates, as early software for the EV-1 may produce the symptom reported when inaccurate speed data is supplied to the autopilot. After doing so, it is recommended that the location of the EV-1 Sensor Core be inspected to ensure that all objects capable of producing a magnetic field (ex. ferrous materials (anchor, tools, tin cans, etc.), electric motors (mascerators, pumps, winches, refrigeration compressors, etc.), high current carrying conductors, etc.) have not been located within at least 3' of the heading sensor. Updating the Evolution Autopilot's software will necessitate that a Pilot Factory Reset (MENU->SET-UP->AUTOPILOT CALIBRATION->COMMISSIONING->PILOT FACTORY RESET) be performed, followed by the Dockside Wizard. The Evolution autopilot software update and subsequent Pilot Factory Reset will cause deviation data stored within the autopilot to be deleted, necessitating that the autopilot once again create its deviation table and report the maximum detected deviation.

Should the autopilot problem persist following the software update and the EV-1 Sensor Core not be affected magnetic fields from objects such as those specified above, then it would be recommended that the EV-1 Sensor Core be sent to Raymarine’s Product Repair Center to be bench checked / serviced.

Regarding the reported AIS issue, unlike the i70 MFIDs, the E-Series Classic MFDs are not designed to process SeaTalkng/NMEA 2000 PGNs featuring AIS data. Correspondingly, the 38400 BAUD NMEA 0183 lead/terminals of AIS receivers/transceivers must be interfaced to the MFD's NMEA 0183 Cable, the MFD's Port 1 must be configured to "AIS 38400", the Chart application's AIS Objects Layer must be configured ON, and the MFD must be receiving a GPS position FIX.
