Seatalk and Garmin - Or another way

[Bigplumbs]

On my new to me Sealine S24 I have a Raytheon ST60 Tridata instrument. This gives me depth from the installed transducer.

As a chart plotter I use a Garmin Ecomap 55dv which is also a depth finder and fish finder. I swap my garmin between boats as you can do with the special mounts

My question is can I get the depth data from the ST60 to show on my Garmin in someway.

I was thinking a Seatalk cable to NMEA Connection or perhaps a seatalk cable to my Transducer plug on the Garmin

Or can you run two bits of kit off one transducer

I am sure there is a clever person on here who knows how to do this

The manual shows it supports NMEA 0183

The Raymarine will be talking Seatalk 1

There are very similar other than Seatalk is bi directional on one wire and NMEA has an IN and an OUT

The purist method would be a converter.

Given you are only looking for one way communication ( ie too listen for the depth) on a personal level I would connect the YELLOW Seatalk cable to the BROWN NMEA in line and see what happens. You will also need power ( red and black). It will work or it wont. Unless someone knows different it wont cause any damage. Its a low power signalling cable.

This would have half a punt of working ( ie is implied on a few forums I have read briefly but not explicit).

If not then buy a converter, or put in another depth transducer. An in hull one will not need drilling and you can link it to the NMEA 2000 backbone ( which I assume you are using?) which will mean less wires to connect when you move it.

If the one wire method works the plotter wont be able to control the auto helm etc or share GPS position with the Seatalk network - it wlll just listen.
