4 into 1 NMEA

[KAM]

Anyone found a neat solution to this without spending a fortune on connectors. I currently have a Raymarine Seatalk converter with those horrible spring terminals. 4 wires in works but its a bit messy to work on.

Assuming you mean 4 wires into one terminal, use a Wago 221 - has a 5-way version.

Thanks they look worth actry. Can you confirm the 5 ways are connected internally it's not obvious from the literature. Are there any mounting holes to hold them down.

 

[MikeCC]

Yes, they are all common. There are a variety of mounting plates available that the connector block can clip in to. Try CPC.co.uk to see what's available.

Great thanks. I've usually avoided that sort of thing like the plague. Everything is soldered but I think those look like a more practical solution in this case. Look a bit better than the ones Raymarine used.

The Wago 221 connectors are perfect for this job. You can often include them in bundles of wiring with cable ties for support, they aren't very big or heavy. You can also key the underside of the connector with some course sanding paper and stick them down with a blob of rapid epoxy (Araldite etc).

Just got a box from screwfix. Surprisingly elegant despite my misgivings. Just need to work out which mounting plates to get.

wago holes big enough to take more than one NMEA strand imo

I can get 4 wires into the Raymarine connector but it's pretty horrible if you need to work on it.

Hold up! What’s this magic trickery you’re talking about?!

Is it really that easy to get multiple NMEA 0183 feeds into the one wire by simply using a wago block? Don’t the sentences just combine into jiberish and talk over one another?

I thought you needed to use a mega expensive multiplexer?!

Mind blown if true!

It's easy to multiplex with an Arduino FYI.... really easy....(it's always the power supply/wiring bit that's tricky to get decent)

You can only connect multiple listeners to a single talker, or it would result in failure as you describe.

That said, i suspect the OP may have a E85001 Seatalk 1 to NMEA 0183 Converter and is possibly connecting multiple Seatalk devices.

 

[KAM]

Yes it's a seatalk converter. Nmea out feeds 4 devices. On the input side I have 2 connections one in the cockpit one in the cabin but only use one at a time. The 7 devices on Seatalk side don't seem fussy about how they are connected.
