Raymarine makes a device called a PC/NMEA/SeaTalk Interface Box. This unit will provide the following functionality:
When used with Raymarine's RayTech
navigation software, the E85001 enables direct SeaTalk communucation between the PC and network, supporting functions like active
route and waypoint transfer. Alternatively, the E85001 can convert SeaTalk datastreams to
NMEA 0183, and
NMEA 0183 sentences to SeaTalk, enabling other NMEA 0183 compatible
navigation devices to communicate with Raymarine SeaTalk compatible
instruments, autopilots, radars, and navigation aids. The E86001
serial data cable (sold seperately) is recommended for connecting PCs to this device.
I use a
Garmin 4212
Chartplotter & High Definition
Radar, but all of my
instruments are Raymarine. I use the above device to interface a Raymarine ST70
Wind, ST70 Tri-Data and ST70
Rudder Angle indicator via NMEA 0183 to my Garmin chartplotter. The Chartplotter has a NMEA 2000 network, however I haven't seen anything that will interface the Raymarine product
family to Garmin via NMEA 2000.
Hope this helps!!
