Yamaha LowranceNET

[Lw1991]

Anyone know where the Lowrance Engine Interface EP sensor plugs into the VX225 HPDI? I have the correct one from Lowrance for the Yamaha 225 HPDI, but no instructions came with it
Thanks

[BuzzB8]

Anybody got an answer?

[Eric E]

Are these for the new Yamahas only, or do the work on older model HPDIs?

[MN Phoenix]

Anyone know??? I'm interested in getting one also.

THis is the link I found. I think this will help you in finding the information you need.

If your engine supports Yamaha's Command Link, it will work on LowtanceNet. They both use NMEA2000. Most 2005 and almost all 2006 motors support Command Link/LowranceNet.

The connector you are looking for is white and has 2 wires going to it, one Blue wire and one white (it is a 4 wire connector but 2 wires are not used). I found mine tucked under the engine where the pitot tube comes into the cowling. I have seen other Yamaha models that have it in the wire bundle on the side of the engine.

I have had my engine connected for over a year and it works great. The engine puts the fuel rate, RPM, Temp, fuel pressure and a few other things on the bus.

What do you need to hook it up. I have a 2005 hpdi and a LMS 332 C. Is this a cable i can get and net work in.

[okie185VS]

Lowrance was working on an adapter cable to connect Command Link to LowranceNet. I have a prototype cable. From the post above it sounds like Lowrance is selling them and calling them engine interface cables.

Make sure and look at your engine to see if you have the white connector with a blue and white wire going to it. 2005 was the switch over year for Yamaha. Some models were Command Link Ready and some were not. Yamaha claims my engine is not Command Link ready, but I found the connector on accident and it works fine. I also have an LMS-332. I added some of the Lowrance LMF-400 digital gauges also.

Thanks. I will check the eng. and see about the conector and check Lowrance web site for the cable.
Thanks again.

It's not obvious from the lowrance website as to what is the model number of the cable. What is it and where can I purchase one?

Thanks.

What is the part number for the Lowrance Engine Interface EP senor? We called them and they don't know anything about it

I looked into the Lowrance part number and it is:

120-31 Yamaha Engine Interface Cable

It is a new product and not on their website yet. I don't think it is in there catalog yet either. I guess you would have to call them to get one.

A few more things on the Yamaha:

- If you want engine trim to be placed on the bus, there are 2 disconnected pink wires that need to be connected. I think this causes your analog trim gauge to stop working (not positive though). Connecting these wires sends the trim voltage to the ECU. Should be in the shop manuals. If these wires are not connected, you will still see trim data on the bus, but it will always read over 100%.

- If you want water pressure and pitot speed over the bus, Yamaha sells sensor packages for this. There are 2 unused connectors in the motor, one labled 'W' and one 'S'. This is where the Yamaha sensors connect. Once they are installed, the ECU will put water speed and water pressure on the bus.

With these 2 mods, you can get rid of all your analog gauges if you wish.

Ok I got the cable now where do you hook it up and is there anything else needed?

[okie185VS]

All you need is the cable. Connect one end to the NMEA 2000 bus that goes to your Lowrance sonar and LGC-2000 sonar module and the other to the white connector with the blue and white wire in your engine. They make Tees that allow you to do this. Maybe this will help:

LowranceNet/NMEA2000 bus:

Terminator----tee-----------------tee------------------tee-----Terminator
| | |
| | |
Lowrance LGC 2000 Yamaha
Sonar GPS Engine


After it is connected, go into second menu and look under 'Bus Setup' and you should see your engine (engine ignition must be on). Select your engine and you will see all the data it is sending. You can then overlay the data you want on your sonar/GPS pages. Fuel rate and engine hours are very handy.

Let me know if you have any more questions.

I guess I cannot print spaces. Ignore the . and this is what your Lowrance Bus should look like.

Brian thanks for the info we have hooked the network system up about a year ago and understand how it works but was not sure were to hook the 120-31 engine cable at on the motor. But you told me the white plug with blue and white. Thanks
Talk to the Lowrance folks in B'ham at Bass master Classic but they did not know witch plug to plug the cable into. Yamaha guys didn't know if it would work or not. They wanted to sale their system

[okie185VS]

It uses the same plug as the Yamaha's Command Link. They are both NMEA 2000 certified systems so both of them work. Of course Yamaha costs more and if you already have a Lowrance sonar or GPS with LowranceNet (with updated software available on Lowrance web site) , all you need is the adapter cable. Can't beat that.
