Nmea 2000 SeaTalk Wifi converter ATM105-A3

The most complete multiplexer and gateway on the market. It works over three protocols: NMEA0183, NMEA2000 and Seatalk simultaneously with Wifi. Compatible with OPENCPN, MaxSea, Weather 4D and others.

​It supports the Ocenav ATM105B remote control (not included) for Raymarine, B&G and Simrad autopilots.

It is intended for boats with mixed navigation equipment based on NMEA0183, NMEA2000 and Seatalk busses.

A very attractive option, it enables the integration of new NMEA2000 devices with the traditional NMEA0183 and Seatalk ones, improving the functionality of the old electronic equipment. It is therefore useful to replace old or non-functional equipment.
