How NMEA 2000 Works

[@chrclmnky]

I was a little out of knowledge about NMEA2k components, now after watching the video, all things are now getting easier. Thanks.

[@jeffreyvanderklip6769]

As a retired electrician I found this video most informative. Very precise and clear I understood all your details. Keep up the good work.

[@BornAgainBoating]

Thanks, will do!

[@burnedagain6187]

Have to agree!

[@Wayno228]

I'm a boataholic and a fishaholic and I love this channel

[@chiphill4856]

Great explanation! I've only installed 3 NMEA networks so far. Not too tough to assemble but I had no idea how straightforward trouble shooting is as well. I also enjoyed your walk through the boat show ✌🏼

[@Devoguy84]

Haha , I was working on a fuel issue on a engine ( was indeed needle valve stuck) while playing this on my phone. Another tech asked me why I was talking about nmea...till he saw the phone playing YT , good laughs all around. Keep up with the good videos !

[@BornAgainBoating]

Too funny lol

[@arnomaas6452]

Great video ! It couldn't get more explanatory and useful , thank you guys !

[@mercmanwon]

Always good to have good terminators

[@iFixJunk]

Quick, clear, and to-the-point. Thanks; I found it useful.

[@BornAgainBoating]

Thank you

[@TomyTekOutdoors]

Great video. This should help me troubleshoot an issue I have with my NMEA network.

Там и так темно ты ещё и очки одел))) а проводку уложили норм 👍😄да очень полезные советы по выявлению неисправности тройников. Спасибо 🤝

[@steverichardson6920]

After this system test would you think it worthwhile to spray all of the connections with Inox and tighten accordingly?

You're an amazing mechanic Aaron! Keep the Faith brother!

[@lawman390]

Enjoy watching your channel. Do you travel to other cities in Fla to work on boats?

[@chiphill4856]

Is it safe to apply dielectric grease to the tee joints?

[@SeansLittleBayofHorrors]

It sounds like you cleaned up some fretting corrosion by working the connections. We get a lot of these issues in under-seat connectors on cars and trucks. Leads to a lot of airbag lights.

[@bigdghost3319]

Thank you so much for this video- now, if needed troubleshoot my network..

[@CarlosRomero-gk1cs]

I work in automotive, and man do I wish they would incorporate a central hub like that in cars.

[@lustfulvengance]

They do, it's called the gateway module. The thing with Marine is that it has to be kind of universal and easy to install because lots of different manufacturers with all different setups use it. When you design a vehicle from the ground up like a car you can cut cost by not making things universal and making it all custom tailored to the vehicle.

[@CarlosRomero-gk1cs]

@@lustfulvengance thats a GM specific thing am I right? I haven’t seen any other manufacturer with some sort of hub. It would just be nice for communication diagnostics to go to one place and eliminate modules there, versus having to go to the separate modules. Then you have the heavy duty side with their J1939 network, that can be a cluster.

[@chiphill4856]

People ask me why boats have more failures than cars? Your example is spot on. They are designed and manufactured differently.

[@chiphill4856]

Sorry with the hat trick question! That is a really sweet wiring job. What make of boat is that?

[@gatgolf]

but did you solve the issue?

[@Jcoop21]

Do you not work for the big marina anymore?

[@outboardfinatic]

Great video. Love the channel man. Wanna see some engine vids if you have any planned. Keep it up

[@markwebb8013]

Nice explanation 👌.

[@anthonycaffarini5687]

Yeah, I try to stay away from those individuals T’s as much as possible. Too much room for error. For the DIYer, I like to cut an old NMEA cable’s s ends off and add butt connectors for my meter leads. That way I can read voltage at all the drops and easily read total network resistance from any where on the network. The N2K meter works great, but it’s $800+ bucks

[@chiphill4856]

So, you insert it anywhere in the back bone to measure resistance at the uncrimped ends of the butt connectors? Is that correct?

[@anthonycaffarini5687]

@@chiphill4856 Yes, with the voltage removed. When you peel back the wire insulation on your test leads, you’ll see blue and white wires,that’s your network wires. You should see 60 ohms on a good network.

[@austinhall7514]

​@Anthony Caffarini will you see 12 volts on a red and black wire

[@anthonycaffarini5687]

@@austinhall7514 yep, that’s a good way to see if you have good voltage going to whatever device you have on the backbone

Shades of 10-base-2 networking! Named for the 2 conductors (shield and core) of the coaxial cable used. Operating at the BLAZING speed of 10Mbits per second. Note, that is BITS, not bytes . . .

[@redseaunderwaterworldsheri5664]

I would like to share my quick question how the radar network signals pass through nema 2k ? how it possible?

[@Gggggh580]

Great!!! when I see the assemblies in the United States I am excited by the organization. I currently live in Brazil and it's difficult to find qualified professionals to make an assembly like this (although there is a lot of demand) do you normally follow any technical standards? can you share? thanks

[@chiphill4856]

ABYC standard covers wiring and other stuff. American Boating and Yacht Council.

[@Gggggh580]

👍

[@BornAgainBoating]

Yes we try to adhere to industry standards, we talk about this a little on our podcast: kzbin.info/www/bejne/rHKzlHiYjsx3oM0&ab_channel=TheBoatersPodcast

[@lb7wade518]

Do you think that Furuno is the best electronics for a boat

[@j.d.saccociates3313]

Use maretron or actisense n2k components! They cost an arm and leg, but make up for it by being skookum as hell

[@gbass7328]

Slight resistance increase due to connector terminal resistance. It can't be expected to be zero for every connector. Apply Deoxit spray to every connector. Video says nothing about NMEA operation just backbone connector/terminator resistance.

[@austinhall7514]

I've encountered something plugged into nmea systems on some of our Coast Guard boats before labeled "STRG DVC." Any idea what it is and what it is for? Onetime, I unplugged it and plugged it back in, and it fixed a no start problem.

[@hectorgarcia2938]

Hello there good morning, I’m one of you subscribers, I found to be your videos very good, in this particular video, at this time I do have the same issue, however I’m unable to fixed, I live in homestead, would you be interesting in this job?, please let me know, thanks

[@BornAgainBoating]

Hello, thank you and sorry, unfortunately we've got too much going on. But, I would say to look up Honesty Mobile Marine and give him a call, he knows people in Homestead that might be able to help :)

[@es1brd787]

How to check the antenna vhf on a yacht if there is nmea?

[@BornAgainBoating]

Depends on a few things, is the antenna a digital antenna or a regular antenna? But the NMEA 2000 is something else outside of the antenna. The antenna will hook up to something that then communicates with everything else using the NMEA 2K. The antenna could be checked with your ohmeter or just get another antenna and then hook it up and see if it works, that's the easiest way to see if it's the antenna or not :)

[@WellsLarry]

Holding my breath thinking why doesn't he just measure the bus for 60 ohms, which you did at the end.

[@BornAgainBoating]

Lol yeah, I wanted to make sure the video covered the whole process lol :)

[@akadcp82]

Why not power components individually?

[@BornAgainBoating]

All components are powered individually, but the communication network needs to have it's own power to allow the data flow :)

[@akadcp82]

@@BornAgainBoating Thanks for the reply. That makes sense, I didn't consider that.

how did nmea get called "NEMA" though?

I'd rather have those 4ways, that's what we usually use

@@BornAgainBoating Definitely makes it easier haha

[@BBD40]

Easier to pronounce, nothing more

Why is it that you only see 60 ohms when you have both terminators on?

It is called a CAN bus not a backbone. Controller area network.
