Interfacing EV-400 autopilot to E 80 classic

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum wlector,

The upgrade should begin by ensuring that the E-Series Classic MFDs have been updated with v5.69 E-Series Classic MFD software.

The SeaTalk bus should be disconnected from the E80's SeaTalk/Alarm Cable. Instead, a SeaTalk to SeaTalkng Converter will need to be installed as a backbone component within the NMEA 2000 backbone. For more information on interfacing the SeaTalk devices to the SeaTalkng/NMEA 2000 backbone, click here. Should the NMEA 2000 backbone be constructed from third party products featuring DeviceNet Micro-C plugs and sockets, then the adapters found here may be used to mate the SeaTalkng interface of Raymarine products to such plugs and sockets. It is also possible to splice a SeaTalkng backbone cable to a third party backbone cable to created a blended backbone. Doing so may make it easier (fewer adaptations) for you to install the Raymarine products.

Regarding your heading question, heading from the Evolution autopilot will be received by the MFD via its SeaTalk2/NMEA 2000 socket and will be used by the MFD.
