Garmin P79S NMEA 2000 > Raymarine Seatalk

[Tsuru]

Hello,
We’d like to connect a Garmin/Airmar P79 NMEA 2000 in hull smart transducer to the Raymarine Seatalk network in our current boat? If possible how is it done?
Note that I searched through the forum and gained a little incite but not an actual answer.
Thanks
Ray

Seatalk or seatalkng?

Seatalkng just buy a converter cable.

Seatalk you can buy a seatalk to seatalkng adapter kit. And then a seatalkng to nmea 2000 converter cable. As above.

Sadly I don’t know which one it is. Visual comparison is that it is probably Seatalk-ng.
Is the procedure as simple as:
1- Determine the network type
2- Purchase the right converter cable (or adapter kit & converter cable)
3- Plug it together.
4 - Power up the system
5 - Done?????

Sadly I don't think you can. The P79 normally connects directly to a chartplotter or ST60 rather than to a network.

I wouldn't call the P79 "smart" it has been around for years and used by a lot of manufacturers, but it isn't smart, just an ordinary transducer.

they make both an analog and nmea 2000 p79

if you have a seatalkng backbone, ( blue / black and white /black cables pluged into black / blue tees) and have a spare empty white port, then yes buy the stng to nmea 2000 adatper cable and plug it in. they make a mail and female cable I think so make sure it's the correct one. if you don't have any free white ports you'll need to add another tee (and backbone cable) or converter an existing tee to a 5 way block (no extra backbone cable needed)

if all the cables are black with flat 3 pin ends then you have seatalk.

Well spotted and an interesting option I may take up.

Seatalk-ng and NEMA 2000 can be interconnected by splicing cables. I have both Garmin NEMA 2000 devices and Raymarine Seatalk-ng working on one network. I used spare cables to get the right ends and spliced up cables. The internal wires use the same color code so the splicing is easy.
If you have the older Seatalk then you need a converter box.

I need to connect Seatalkng to NMEA 2000 so I bought an Ancor "NMEA 2000 Male Field Serviceable Connector".
It has the tiny connectors recessed where you can hardly get to them and they expect you to solder the wires to them.
I think you'd need to be pretty competent at circuit board soldering to get that sucker connected.
I took it back and ordered the Maretron version. It looks like it uses screws and is more in keeping with my technical skills.
