NMEA 2000 and the 1.8L

Summers420us · Nov 26, 2016

Has anyone successfully connected the 1.8L to the NMEA 2000 network. I have read all the old threads, but I do not see anything conclusive for the newer boats like model year 2016.

Connext boats do have a N2K network. The only standard pgns are for depth and water temp from the transducer. Everything else is on proprietary pgns so the only way to read them into a standard mfd would be to buy something that translates that info into standard pgns (no such thing for the connext boats yet) or build and code something custom. I did the custom thing and decoded the connext joystick and posted a thread a couple of months ago. https://jetboaters.net/threads/connext-joystick-nmea-info.11513/

This was not easy as I had to add some raw electronic components to a Arduino Mega and code it to even pick up the proprietary pgns and their hex values to write out to my laptop in a log and realtime. I don't think it is worth the time and effort to take it further but if someone else with CANBUS or microcontroller coding knowledge wants to give it a go then hit me up in a PM.

Ultimately much of the engine info is still being sent over the custom Yamaha Canbus for the 1.8l engines. The connext screen is the hub for the radio can bus, NMEA 0183 (gps speed pick up) NMEA 2000, and the custom Yamaha CanBus. I don't think the Yamaha bus for the 1.8l is the same as their outboards which would make this easier as the outboards are supported for MFDs. Would have been great of the connext developers to at least output to standard pgns where data was availabe to do so like rpms, battery voltage, charging voltage, etc.

I swear.. reading that wad like watching a french movie with no subtitles... I have no idea what you said!

So short answer is not possible unless what works for Yamaha outboards works for the inboards as well; or you are a data/electronics geek with too much time on your hands. I have not read anywhere of someone trying the outboard methods but my guess is that would not be the same.

The question is, how do we get Yamaha to hire @Mainah as a consultant. Those would become the flashiest boats on the planet in about a year. Seriously.

If someone would make a device to connect to NMEA2000 I would be happy to throw my money at them

I have a question the Transducer you are speaking of is the N2K plug in the Stern or were you just using the N2k plugs that is part of the Deck wire harness in the Bow? Did you ever try the NMEA Yamaha Engine Interface Cable by Lowrance?

I only used the nmea plug behind the helm. I made my own plug. Even if the lowrance pkug fit it is the software that needs to interpret the data coming over the network. Since the depth, temp, and speed are standard pgns there should not be any problem with any NMEA HID reading those.

I haven't been able to get any hardware to read any engine data on my CARB version '17 212. I have a Simrad Go9 and all it will do is recognize that there's an unknown device hooked to it. I've tried reading data from both the CAN network and the low speed network with all kinds of hardware and software with no luck. Thanks Yamaha. Not. Pretty retarded that I can't even read or clear codes on this boat.

What are you connecting to your Can Network and how? (Just Curious)

Thank you.... Do you mind if I ask a couple more questions? Have you ever researched or tried NoLand Engineering - RS11 V4 CANbus Engine Data Converter or any software from actisense? Thanks in Advance..

The only thing I tried was building my own canbus reader with an arduino and a mcp chip. I used actisense software to observe the pgns and values. All of that was for the n2k network. It is my belief that the n2k network is used for communicating with the spu, joystick, transducer, and gps. I think that connext picks up the engine data over the engine canbus for each engine.

My whole purpose of communicating with the n2k network was trying to build my own gps speed control by automating the the rpm up and down from the joystick. I gave up on that project as I was not happy with my results or how much time it was consuming. I bought ridesteady instead.

Any more tinkering I do with my boat at this point will likely be limited to more common stuff like ballast and audio. With recently moving, buying a new house, plans of buying lakefront land to build custom, one college freshman and two more headed to college in the next 5 years; my toy budget has taken a hit so even those things are going to take some time.

Thanks for your help and understand, My daughter just graduated high school, she is taking the classes to get her Captains license.. I am going to buy a couple 19's she can rent, then she can take people out on the 242.. she can pay for her university with the earnings from boat business..

Do you go to Bimini with the group?

I have never been on the Bimini trip. I was not able to go this year because of moving. My whole family is excited to go and looking foward to it in 2018 provided timing allows.

I am excited.. I live next to Haulover, Bimini is 45 miles from me.. I want to buy the GPS, VHF, etc black Friday.. if you come look forward to meeting you..

Not to hijack the thread but how do you have your GO9 mounted? I was looking at one of those today. Thanks.
