Stus-List Re: Seatalk NG / Nema 2000 device connections

[Shawn Wright via CnC-List]

We added an EmTrak B951 last spring and it has been great, more useful than
radar in most cases (although radar was great the few times we needed it -
we were even able to spot humpbacks nearby that we could hear while
ghosting along in the fog). A big advantage of AIS is being able to hail
commercial traffic by name from a safe distance if we need to. We haven't
done any night passages yet, but knowing that we are as visible as possible
was a key reason for getting the transceiver vs. a receiver. Our solar arch
came with a separate VHF antenna and wiring, so I replaced it with a
homemade AIS specific one and it will act as a spare for the masthead
antenna as well by just switching cables. Range is good, with lots of
visibility to 30+ NM in most areas around here, less in the inlets/fjords
of course.
I don't have AIS integrated with the VHF radio, but did install a new N2K
backbone with the other new gear, mainly B wind/dst/compass/gps and
plotter. Having not sailed much with accurate wind instruments, I
appreciate having them, especially when the wind comes up when going
downwind - sometimes it is easy to get complacent with a lot of sail up in
25-30kt in warm summer air, then get a surprise with a windshift or course
change!

Thanks Dwight

We do not have radar so everything we have to make them see us helps

Happy 2022

I see. I have all the Raymarine gear displayed on instruments in a pod above 
the companion way. Speed, depth, wiind speed and angle true and apparrent and 
also a graphic display that gives me digital apparent wind angle and windspeed 
readout or any othe combination of up to 4 parsmeters display. I pay careful 
attention to apparent wind angle and speed thru the water when trimming for 
performance short legs and vmg for longer hauls. I hope those big ships are 
watching for you but happy at least that you can see them. I rely on my old 
Furuno radar display in the cabin but visible from the wheel when unexpectedly 
caught in fog. I do very little after dark sailing. Sometimes it’s a nightmare 
just keeping the simple instruments i have working. More wire more connections 
more possible failure spots.

Hi Dwight

Short answer is NO – not always.

Better answer is that I want other vessels to see me when doing coastal trips 
at night and in the fog. We already receive AIS so I see the big tankers that 
will plow us under doing 14 knots and I want them to see us before that happens.

The rest of the gear?  I like knowing Speed over Water especially when racing.  
I like not hitting bottom so depth can also be important.  Smart people know 
the wind speed and direction but for the rest of us having it displayed is nice.

For the setup it turns out that Raymarine has a SeatalkNG to Nema 2000 spur 
connector and you can plug in directly to SeatalkNG backbone.

This does give me a reason to climb up the ladder in the winter to run my newly 
installed diesel heater and tinker with the boat though ..

All the best

Mike

Mike. Do you really need all that gear to sail your boat well or are you just 
interested in the challenge of seeing if you can make it all work, at least 
long enough for proof test. Hahaha Happy New Year

Sounds like I need a A06045/A06075 SeatalkNG to Nema 2000 cable and plug right 
into Seatalk NG backbone.  That is pretty simple

Now I just have to climb back into the cold dark boat to see what backbone 
currently looks like so I will know which of and how many of the other $49 each 
Seatalk NG bits and pieces I will need to add

Yes, you can buy an adaptor or make one with a field attachable connector.  
Seatalk NG is or rather was Raymarine's attempt to make the NMEA 2000 standard 
effectively proprietary.   I have a Seatalk NG backbone and a range of NMEA2000 
devices - it works seamlessly.

Likely a question for Fred Street

Currently Persistence has Raymarine i50/i60 Speed/Depth/Wind and Raymarine a65 
multifunction display/chartplotter connected via Seatalk NG network

Have just acquired Em-trak B923 AIS transponder with built in antenna splitter. 
 Wish to also connect B923 to a65.  B923 has Nema -0183 and Nema2000 
connections. A65 has SeatalkNG and Nema2000 ports.

A65 currently using SeatalkNG port to communicate with i50/i60 instruments. 
Nema2000 port unused.  Power connector has only three prongs so do not believe 
this model has the Nema 0183 wiring

How do I most easily (and cost effectively) connect the B923 to the a65 so that 
I can see AIS targets?

Can I simply purchase a SeatalkNG to Nema2000 cable and plug B923 into 
SeatalkNG backbone? 
https://www.defender.com/product3.jsp?path=-1|344|2028705|2028879=1108756#
That seems too simple a solution and too good to be true.

Alternatively do I need to set up a Nema 2000 backbone in addition to (and 
separately from) the existing SeatalkNG backbone and then connect to the Nema 
2000 ports on the a65 and the B923?  Will this cause issues since the a65 is 
also connected using SeatalkNG port to the Seatalk backbone?

This seems very complicated compared to the older Nema 0183 connectivity.
