SeaTalk connectors

I have a Raymarine SeaTalk network installed that uses small round connectors. I have an opportunity to buy a S100 wireless remote for the autopilot but it has a larger flat connector. It looks like I can buy a converter cable but I donít which one. When did they change? Will it even work?

Re: SeaTalk connectors

The small round connectors are Seatalkng which is Raymarine's proprietary connector for NMEA 2000, the large flat 3 blade connector is Seatalk 1 which is a Raymarine proprietary protocol. Tthere's also a Seatalk 2 5 blade connector weirdness that even Raymarine seems to not want to admit ever having existed, best I can tell it's a limited NMEA 2000 implementation. There is a converter for Seatalk 1 to ng. I don't know that the adapter will support all devices so make sure before you layout the cash.

I am a touch confused though which autopilot? I don't know all the raymarine stuff by a long shot but how is there a Seatalk 1 remote that interfaces with a later gen autopilot?

Re: SeaTalk connectors

I expect the OP doesn't have Seatalkng but the earlier ST50 round connectors. You probably need an adaptor cable like this You should be able to plug it into a spare connector on one of your instruments

Re: SeaTalk connectors

The older devices that had a blackcase instead of gray and were often labeled "Autohelm" used a round Seatalk plug. The Seatalk 1 was changed to rectangular plug with 0183 protocol, there was an adapter as I installed one just a couple decades ago. I believe the adapter is shown on the attached website as part number A06047.

Re: SeaTalk connectors

I don't think the A06047 will help the OP as that is a Seatalkng connector ...
He probably needs an adaptor D187 like the one I linked

Re: SeaTalk connectors

Well I learned a thing then, didn't know about that earlier connector, is the protocol just straight Seatalk1? If so you can just use 1/8th inch spades to the pins on the flat connector side, no need for a Raymarine connector on that end. Obviously I don't know whats going on the round connector side but maybe a similar option?

I stand corrected, even your part number seems to ring a bell.

Re: SeaTalk connectors

Seatalk 1 is a flat 4 pin connector

Seatalk(hs): started as water'proofed' RJ45 network connections.

Seatalk(hs): Later versions of Seatalk(hs) use 'raynet' cables, which have a small round connector (like a mini Din) with a ring collar on the cable. These are usually black.

Seatalk(ng): use smaller round connectors with no collar. The end is usually blue or white and the ring collar is on the device rather than the cable.

Re: SeaTalk connectors

Why post mis-leading information?

Seatalk 1 as sold by Raymarine is a 3-pin flat connector (12v, data, 0v) and can be connected via the D187 adaptor to the earlier Autohelm ST50 instruments and st7000 autopilot controller units by their 3-pin round connections.

Both of these connector types can clearly be seen here

ps Raytheon bought out Nautech who developed and made the Autohelm range of autopilots and instruments in 1990. Later re-branded as Raymarine after a management buy-out

I believe the two communications/wiring formats of Seatalk1 (round 3 pin and flat 3 pin) are the same, so your solution of spade connectors should work. Just follow the color coding.
Where are you located?
I may have some spare flat Seatalk1 connectors on my boat in La Paz BCS.

I was just offering up an idea for the OP, thanks for the offer maybe they can take advantage, raymarine seems to make their cables out of the rarest finest materials made of magic and fairy dust for the price they charge for plastic and copper...

Re: SeaTalk connectors

I talked with Raymarine tech support. The. S100 with the flat connector is SeaTalk1 protocol. My AP is SeaTalksg which is NEMA2000 protocol. Different connectors different protocols. A converter box from Raymarine is about $90.
