looking at an interface between the kad 44 and my ipad

i dont have a seatalk setup, v unlikely to ever install this

which of the two interfaces would be more future proof ?


this is from the dutch supplier who can ship to the UK:

Link to the engine gateway:

Since SeaTalkng is a bespoke solution by a single company then the DeviceNet solution is theoretically more future-proof. However, as the difference is purely connector geometry, I would expect both to outlast the application.
 
I agree 100% with Sir Dougal. Get the generic nmea2000 connector aka devicenet. No point using seatalk ng connectors if you don't want a raymarine stng network for other purposes.
 
tnx guys.
i dont have any other interefaces on the boat, only wifi, which way would be simpler / more reliable ?


here is the reply from the dutch supplier:

Do you have an NMEA2000 bus on your vessel? If not you need to create one, best with a starter Kit. It consists of a power lead, a few T connecters, two Resistors and in most cases one or two backbone cables.

I do not sell these but here you can find an example (I just searched for “NMEA2000 starter kit UK” in google and picked the first one:
https://www.force4.co.uk/navico-nmea-2000-network-starter-kit-uk-version.html

This one connects more devices:

And here is a normal T piece:

https://www.force4.co.uk/navico-nmea-2000-tee-connector.html?sqr=NMEA2000&

For each device you will need a T piece so wou will need three in total, One for the Wifi adapter, one for the engine interface and one for the power cable.


SeaTalkNG is NMEA2000 with different connectors. If you need a starter kit, every boat shop has these.

(i would need 3 seatalkNG connectors ??)

I agree with the previous two posters, going afresh into something and going proprietary is imho wrong
check the topology of a NMEA2000 network (it's easy!) and mentally organise where you want each device and check routing from one to another.
Then you buy the bits you want:
I power cable (typically yellow)
3 tees or a 4way tee which is probably cheaper than 3 individuals but limits you in having them all together with no patch cords in between (effectively a zero length bus which is not a problem)
2 terminators
and whatever you want for connecting in between.
If it's convenient you can have the three tees together and have patches running from them to the 2 devices plus the power cable. In which case it would make sense to have all that near the el.panel.
