Adding EV100 to Seatalk network

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum James,

The Evolution autopilot cannot be interfaced to the legacy SeaTalk devices in the manner which you have described. The Evolution autopilot components will each be interfaced as spurs to a powered and properly terminated SeaTalkng backbone which will include a SeaTalk to SeaTalkng Converter as a backbone component. The unpowered SeaTalk bus containing the legacy SeaTalk devices will then be interfaced to the SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter. As the Garmin 441S manual indicates that it supports NMEA 2000 communications, it too will be interfaced as a spur to the SeaTalkng backbone. As you have suggested the SeaTalkng will need to be powered, as will the ACU100. Please click here to view a Raymarine Forum thread in which a I had addressed a compatibility issue between the latest Evolution autopilot software and how it may be resolved by downgrading the software within the Evolution autopilot components.
