Help with Seatalk

[olam]

Hi All,
My new (to me) boat has Raymarine with Seatalk etc.
I am moving the plotter up to the cockpit and need to get a seatalk 1 feed up there .
Can i splice into a cable on the ST60+ instruments or can i just get a cable to plug into the NG block
with a Seatalk 1 plug on the other end ? If so which outlet/colour cable?

I think I've added a photo

Thanks in advance

No.

If you are just moving the plotter, why not just get a longer cable, or extend the one you have ?

You have a Seatalk 1 to NG converter there, where does that go? I’m assuming the chart plotter by 1 of the 2 black/white cables? Or maybe you have a new AP operating Seatalk NG?

I do have a longer cable i could run there but then figured the Seatalk must be connected
to the ST60 already.I presume it can just be picked up with the right cable.

I think the Ng is there for the newer Raystar gps ariel ,I guess it converts to seatalk 1

Seatalk 1, whilst I hate Raymarine stuff with a passion, is actually quite good because you can set it up in multiple ways and use different ways at the same time. So you can do a bit of daisy chain, add a spur, splice into it or make a star type arrangement.

So I’d say if you have a suitable Seatalk 1 feed by the way of another instrument next to where you’d like the chart plotter then splice it? If you’re doing the job properly you’d add a D244 junction block with a few short tail cables.

Remember to remove or make the dead end safe from where the plotter used to plug in.

Seatalk 1, whilst I hate Raymarine stuff with a passion,<snip>

You and me both. Just organising the installation of some new Raymarine kit, supplied by the customer. Axiom 9 plotter, under deck AP, i50 and i60 Depth/wind. Everything on NG, except the plotter, which is N2K only (no seatalk of any description and no 0183). Converters, tees and all manner of spur and backbone cables abound. No 0183 on the plotter means no GPS feed for the VHF, without another converter. What a pigs ear !

Fortunately he left the choice of AIS to me, so i'm fitting an em-track, which will supply N2K AIS to the plotter and 0183 GPS to the VHF simultaneously :encouragement:

Yes, if the plotter needs Seatalk1 then you can connect it to the instruments. You can't use the spare white connector on the SeatalkNG block as that's SeatalkNG/NMEA2000/CANbus, not 4800baud Seatalk1, but you can tee into any of the wiring emanating from the yellow connector and the ST60s.

The "official" Raymarine way would be to unplug one of the flat connectors on an ST60, plug it into a 3-way connector block, then plug in a short SeaTalk1 cable back to the ST60 and another one of whatever length you need to reach the plotter. However, it's also perfectly acceptable to cut and join the cable using any respectable method like crimping, spring terminals in a junction box, or even solder and adhesive heatshrink (though I probably wouldn't do a tee that way).

The ST1 in the picture goes from the converter block, daisy chains through the two instruments, then heads out of the picture to the right. Do you know what that goes to? If it's just heading down below to the old plotter position then you can reuse that output from the instruments without any new tee - either pulling up and reusing some or all of that cable, or just plugging a new cable onto the instrument.

That seems a rather extreme way to describe the need to make a single mechanical conversion from one type of plug to another

Raymarine sell cables with SeatalkNG at one end and DeviceNet at the other, that's all it takes to make the combination work. And while you as a professional obviously aren't going to fanny around home-making them, it is perfectly straightforward for a stingy DIYer to do so to save the £20.

So you needed to convert to DeviceNet anyway

Not as neat as a pure N2K network Pete.

We have one of those connector cables. very short devicenet to NG, will collect at the plotter to convert it to NG, then route to the switch panel area.

Yup, and we need to convert devicenet to NG again to feed the AIS data into the network.

A straight N2K network is tidier. Raymarine seem to be making some of the later plotters with N2K connections, but other kit is still NG. Simrad did the same with Simnet, now seem to be changing over to N2K.

Thank you all,I'll prob just splice into the seatalk .
