The LCX-38 has all you need as far as display capabilities. If you want more display options, something like a Lowrance LMF-400 is great. What you need to do is establish a NMEA2000 instrument bus on your boat. This involves running the NMEA2000 cable with terminators at both ends from the engine area to your helm area. Your LCX-38 will have a wire lead on it that can supply the NMEA2000 bus with the power it needs. After that, all you need to do is buy and install the ep-20 and configure it on the LCX-38.

The cables and connectors for the NMEA2000 bus are fairly pricey, but you should be able to get everything you need for under $100. The ep-20 is something like $58 from BOE Marine.

The LCX-38 manual will have details on how to use engine sensors and the Lowrance site has downloadable manuals for setting up and using the NMEA2000 bus. Start here:

BOE Marine (A THT sponsor) has all the equipment you need at the best prices I've found. Jim at BOE is very familiar with this setup and will give great advice.

Forgive me if I missed this, just read the whole thread. I see where there are references to NMEA not working on older suzis but all the literature says "some functions may not be available". All I really want to get is fuel management data. I have twin 2001 Suzi DF115's, the first year they were made. I believe the engine interface module "converts" the data from the computer connector to the NMEA format for the network. I'd love to use the SMIS gages if I can, either 2" or 4". I have the Suzi tachs with the warning lights, etc on them. My fuel gages on the C-Dory TC255 are terrible. The sending units are nearly impossible to lay a hand on (twin 75G alum tanks, one in each Cat Hull).

There seem to be some experts here, does anyone know what will/will not work? If nothing will, what gages could I use, don't really want to cut into the fuel lines, much of my time on the water is spent at low speeds and the "fuel turbines" may not be accurate at low flows!

Thanks

There are NMEA fuel flow sensors that are independent of engine type, your engines predate nmea 2000.

Thanks, I know that. I was under the impression that the engine interface takes the engine data from the laptop connector and converts it to NMEA format. If this is so, makes no difference if the engine itself is NMEA compatible or not... Not true?

sorry, don't understand your question, beyond my pay grade I guess

The output at the computer hookup is just small voltage pulses. Since it hooks up to a laptop normally, the software in the laptop makes the conversion to something useful for the diagnostic program. If the engine were truly "NEMA 2000" compatible, you wouldn't need the interface. The interface takes those small voltage pulses and converts them to a stream of NEMA 2000 data for the SMIS Gages and other things on the network. The problem with the earlier engines, I guess (that's what I need to know) is that the small voltage pulses don't contain all the data that the later model engines do, like fuel flow info, etc.

Hope that's clear (and correct)!

Default garmin 4212 and suzuki

I have been searching the net for some answers fro what i thoght was a simple question
can the Garmin 4212 be conected and work to a pair of DF200 2007 suzukis. I was sold a bill of goods by an installer and now want a fix. I have the cables, adapter tees and ep20 adapters in place.
What needs to be done or can be done?
as a last resort I would install an other screen made by loweance,
I want the pretty pictures I have seen of gages on one screen, I can dream cant I?

You will need a EP-20 and a LMF-200 or 400 gauge to configure the ingine interface.

Default Suzuki interface

Hi all,
I have just set up my Suzuki 06 DF140 to interface with the Lowrance HDS7M by using the Suzuki engine interface cable (part number 120-55) and NMEA Network starter kit (124-69) from Lowrance.
I am using the chart overlay and have the fuel rate,fuel used (trip) and fuel left (in tank) but it give you all the info from the motor if you want,oil pressure,engine temp,engine hours,voltage,
and more all on the Lowrance unit without any other gauges needed,the only thing I didn't worry about is the trim I still use the Suzuki gauge on the dash ATM when I work out where to find a Y piece to plug in both trim cables ill set that up.
I hope that helps some people out as it took me a while to find what I needed over here and even before the Suzuki dealers new what was needed to do the job.

Cheers Dennis

A LMF (or SMIS) gauge is needed if the plotter is not a Lowrance unit.

I've not been able to display oil pressure and engine temp from my 2005 DF115.

Default The Suzuki

The Suzuki/Lowrance dealer tried to sell me the gauges and more cables than I needed at first until I did some searching and from what I read on here I dug a bit deeper to find out about the Suzuki / Lowrance interface cables and it was simple to set up.
I just thought id put it out there about not needing the gauges for the Suzuki / Lowrance set up.

No oil pressure or temp info is available via NMEA2K from any Suzuki. DF300 does put out water pressure.

This is direct from the Lowrance site:

The Suzuki Engine interface can provide the following information over the
NMEA 2000 network:

Engine RPM
Alternator Voltage
Engine Hours
Fuel Flow
Engine Trim
Fuel Used
Trip Fuel Used
Seasonal Fuel Used
Speed over water (DF300 Only)
Water Pressure (DF300 Only)
Current Gear (DF300 Only)
Standard Diagnostics
o Overheat
o Low Oil Pressure
o Over Rev
o Low Battery Voltage

Hello to everybody,

this is my first Post here in this Board.

Some Words to my Person, my Name is Tom, I'm 44 Years old and I'm living in Hamburg/Germany.

I read the Post's about the EP-20 and Lowrance LMF-400 a long time, because here in Germany nobody knows this Parts for the Suzuki Outbords.

I installed these Parts a few weeks ago and I was wondering, that my Gauge shows me the Engine Temperatur under the Menupoint Eng.Tmp

It's a 2006 DF 140.

Sorry for my bad english


Greetings from Hamburg

Tom
