Connecting Yamaha to Garmin

[SmokyMtnGrady]

I searched this site and others and I could not find the answer . I have a 2017 Yamaha 4.2 with digital controls. I am buying a Garmin 942XSplus that has the ability to interface with Yamaha using that J something or the other code.

So, is the plug at the motor or did Yamaha think it through and offer a pig tail at the helm integrated into digital command cable or then again. Is it with the command link cable ?

Garmin sells a Yamaha plug that plugs directly into the J2903 port ( I don't recall the actual number). That cable is only a meter long which gives me hope the connection is either with the binnacle or the command link system underneath the dash.

What say you guys?

You need a NMEA 2000 network which I assume you already have. I just bought a Yamaha plug to plug into the network hub (can't recall the P/N), spliced it into a standard NMEA 2000 cable (10m) that plugs into the NMEA 2000 network and the Garmins (5212s, 5208, and 94sv) all show engine data just fine. My Yamahas are 2006 F250s and 2011 F150 models. It is a standard CAN bus (auto like) and the Garmins and NMEA read it fine. No interface required. The ECU digital data output is on only two wires. The red wire is not needed if you have your NMEA bus powered and the black (common) is redundant, but I hooked it up anyway. I'm guessing the digital control is similar with the difference being the ECU puts out the same digital data.

Thanks WS,
Garmins new line of plotters has a port that is specific for engine data. It's called J1939 standards. It's not on the NEMA network, it's a stand alone engine network as it is. If I connect the plotter using this J port to the 4.2 motor, my plotter essentially becomes a one big gauge and has all the functionality of the Yamaha command link screens.

Garmin sells the plug which fire the J1939 on the plotter and connects to a Yamaha plug which feeds data to their Yamaha flat screen gauge displays. I am trying to find out where that plug is located. This is different than NEMA out which the plotter also uses.

Thanks.

Cool! Sounds like someone was thinking!

Hey Smoky unfortunately I'm new to yamaha, so I can only give you a half answer because I don't entirely understand the Yamaha bus.

I recently switched my boat from Nmea 2000 to J1939.

For me, I had one of the Yamaha 5 port hub units (6Y8-81920-01) up under the dash already. Originally the boat had the Yamaha N2K gateway which bridged this to the N2k network and displayed the yamaha info across all my devices.

However, I had seen the J1939 demos at a boat show and thought it was pretty slick. So I bought the J1939 Garmin cable on amazon for $25: https://www.amazon.com/gp/product/B07C9GYYS3

This plugs between the chartplotter and the Yamaha 5 port hub on one of the "DEVICE" ports just like the 6Y9 gauge would. J1939 worked great, the Yamaha engine page popped right up.

Now the bad news. Apparently Garmin can't SHARE the J1939 data. So now I went from having two chartplotters sharing all the NMEA engine data between them (and any other devices) to instead just having the yamaha gauge page on one chartplotter. I've ordered a second J1939 cable so I can access it on both but I will admit this seems really ridiculous.

The good news is this...I only can afford 1 new plotter at this time. Lol.
