Depende de que Raymarine se trata. Los antiguos solo trabajan con Seatalk, los modernos le han añadido NMEA2000
El tacktick mn100-2 solo puede leer datos de NMEA0183.

Si tienes un instrumento de Multifuncion o un Ploter Raymarine, este tiene salida NMEA0183. Entonces puedes utilizar esta salida y conectarla al tacktick mn100-2. Luego en el menu activar y calibrar la recepcion de dao NMEA0183

" 6.2.10 No NMEA data showing on external instruments.
From any Digital instrument enter Setup and Calibration Mode (page
18) and scroll through to the Health Chapter. Check the signal level
and battery status of the NMEA Interface. If the signal level shows a
value of greater than 3 then check the data connections and the
settings of the NMEA source equipment to ensure that NMEA 0183 is
being transmitted correctly.
* The “Master Instrument” is the instrument which was used to power up
the entire system. This instrument may be different each time the
system is used. If you are fault finding and are uncertain which
instrument is the master the switch off the system and switch on again.
The instrument which you switched on is now the master"
