Is it worth the hassle converting Seatalk 1 to N2K

I don’t have first hand experience, but it’s one of the examples Raymarine give:
View attachment 102973

All the transducer data in that network has arrived over N2k, but some of it is being displayed on ST1 instruments.

That’s brilliant, thanks loads for digging that out Pete. Thanks to all, another great forum result!

Definitely works very well converting from ST1 to NG/N2K, i hadn't considered it converting back the other way when i typed post #6. It does make some sense that it would work, but a call to Raymarine would confirm. If it does, then option 2 in post #6, whist retaining the ST60s would be a good choice, IMO.

Hi Paul

Correct me if I'm wrong, but AFAIK the Seatalk to STNG e22158 converter is just a cable converter as the STNG cable carries an extra cable for Seatalk.

This kit will NOT convert Seatalk1 to NMEA 2000. If you remember, this is the problem I had, which is why I needed an E85001 and an Actisense NGW1 to get the Seatalk Data to NMEA2000 ( and back again so the autopilot to get waypoints ).

Edit: Just looked at the specs and apparently it does have a processor that will convert the data. When I spoke to Raymarine ages ago they said it was just a cable, so I was confused. I can't find a complete list of the messages it will translate though.

I've fitted a few of these kits Dave and they work well. I've used them where there is an existing ST bus (mostly ST60 displays etc) and i've fitted newer MFDs.

I thought yours was a different issue. Didn't you want to retain the analogue transducers but replace the displays, or have i got that wrong ?

Hi Paul, I had to keep the transducers and use the displays to be able to to calibrate and get the info onto seatalk.

An E85001 now converts that to NMEA 0183 and then an Actisense to NMEA 2000. I've just ordered one of the Raymarine converters to see if that will work to replace the other bits, but I have a feeling there was a reason we couldn't use that ( other than raymarine telling me it wouldn't work )

Methinks Raymarine told you wrong Dave. If the analogue transducers are connected to the ST60s, leave the ST bus intact but disconnect the ST bus power supply. Fit the ST-STNG converter kit. If you only have a B&B MFD connect it to the ST-STNG converter with a converter cable. If you have more than one N2K device you can link the N2K network with the STNG network with the ST-N2K adaptor cable. Be aware, the old ST network should not be powered and it's best practice to only have a single power supply for the STNG and N2K networks.

Thanks Paul... the power to the ST network might be an issue as it goes all over the place.

It all comes off the same switch on the panel though from what I remember. In fact I've got a feeling it get's it's power from the autopilot. I'll have a play when I'm next allowed at the boat

Common way to disconnect the ST power is it open the insulation on the first device in the bus and snip the power line.
