It is an NMEA 2000 Seatalk to WiFi smart gateway data converter that enables PC’s, tablets, and other mobile devices to connect to GPS, AIS, and existing instrument systems on board.
Includes remote control for autopilot and wireless charger.
Both models, ATM105C2 (without Nmea 2000) and ATM105C3 (with Nmea 2000) operate directly with any Raymarine ST1000 to ST7000 autopilots and S1/S2/S3 Smartpilot computers.
The ATM105C3 can also operate directly the Evolution autopilot series, Simrad and B&G pilots (Simnet based).
The Raymarine Seatalk-SeatalkNG converter is not necessary.
