Raymarine interfacing

[fireman181]

Electronic gurus.......I have an ST 60 wind instrument linked by sea talk to an ST 60 speed/dist/temp instrument, and also have a seperate Garmin GPSmap 392. The Power data cord to/from the GPS unit has NMEA Out and In wires.
Question......can I connect the two systems together, and how?, I can not find any terminals on the back of the ST60 instruments that would work, I think I need to interface with the sea talk line, but how???

Any info appreciated......Buck

Raymarine sells a SEA TALK / NMEA adapter...somewhere around $100 I think....converts one to the other and vice versa. You'll have no difficulty connecting it.

What are you trying to do??? The ST60 wind instruments gain nothing by being connected to the Garmin GPS... and the Garmin GPS doesn't really gain anything from being connected to the wind instruments.

If you're trying to get data from the instruments and the GPS for something else, then you'll probably want a NMEA/SeaTalk multiplexer.

I don't see how connecting GPS to Wind & Speed Instruments does anything. You should connect the GPS to NMEA input of you Autopilot (if you have one).

I thought connecting the two would give True wind direction while under way, and also tacking angles, useful while racing,...........but not worth $100 ...........Thanks

If you have the ST60 Tri-data, then you'll get true wind angles, based on the knotmeter readings... of course, if there's a strong current, it won't be 100% accurate...but close enough for most people.

Connecting Wind to Speed instrument will gives True Wind speed and direction. I doubt there's NMEA input on ST60 Wind and Speed. Also, don't see how GPS/NMEA adds any value. Of course, I could be wrong about GPS. I'm happy to learn new things.

fireman181,

Since you're already connected to the ST-60 speed log, all you need to do to see true wind speed is select it from your wind instrument display. Press the true/app button to toggle between the two. Pressing the tack button will show the tack heading info on the digital display (the analog pointer will still show the true/apparent wind angle)

You know what they say: RTFM

(If you don't have the manual, it's available at the Raymarine website)
