Random Quote: Catch them all and let the wife sort them out
Looking to add a fuel computer to the boat and would be awesome to have it read MPG. To do this it needs data from a GPS. Well, my GPS protocol is NMEA 0183 and the Lowrance LmF-200 uses NMEA 2000.
I searched THT and did not find anything on it but two related threads that did not yield anything useful.
To those who may post it, no I'm not going to be buying a new NMEA 2000 GPS or LowranceNet to do this, if I have to, I'll just use GPH readings and figure manually.
Is there a way to convert my 0183 signals into 2000?
THANKS!

I think that the NMEA 2000 can read some 0183 sentances, but not visa versa. Go with Navman, which is 0183 all of the way. The units are very similar and Navman is well proven.
Bob,
Are you referring to the Navman 3100 or 2100? I want a smaller gauge if possible....will either one show MPG?

My original subject line should be the opposite, convert 0183 to 2000 as it is the GPS that will be giving the fuel computer the data.

no not possible w/anything on the market, it would probably be more expensive than the lowrance nmea2000 paddle wheel ($50) if a converter was available anyway.
About the only thing you can do is to buy the Lowrance LMF 200 AND buy a Lowrance GPS antenna. This will feed the speed reading to the gauge and it will calculate the MPG for you. You would have a GPS antenna for your existing GPS and another just for the Lowrance LMF 200.
I looked at this option and went with the Yamaha Fuel Management Gauge for my boat and it connects to my NMEA 0183 GPS.
Decided to do some digging on the Lowrance site and downloaded a few info pdfs.
Taken from the horses mouth:
NMEA 2000, which is a radical departure from NMEA 0183. NMEA 2000 devices will
not communicate with NMEA 0183 devices. The NMEA 2000 was planned from the beginning to be a consistent system capable of incorporating future growth.
Looks like it will be hand calc of NMPG as I really don't want to fool with the paddlewheel. I want to maximize cruising economy and see how exactly what my boat burns under different conditions, etc. Also a night day difference from the bouncy analog fuel gauge.

Just remembered something... The LMF 200 will not show MPG even with speed sent to it by a GPS. Only the LMF 400 will do this and again, you can simply connect the GPS antenna to the network and the LMF 400 will pick up the speed data. No need for a paddle wheel thingy.

Firefly, please don't tell my LMF200 that. Here's a photo of my LMF200 showing MPG. It works using the NMEA2000 output from my C80 and it works using the NMEA2000 GPS output from my Lowrance GPS puck but it won't work well using both at the same time and it won't work at all with 183.
C-Dory 22 Cruiser w/trim tabs, Yamaha 75. Skating rink flat water, empty boat 'cept me and a 6 pack and only 10 gallons of fuel aboard. That's the best mpg I've had so far at that rpm. Still calibrating but it appears to be accurate.
I actually prefer using the Lowrance GPS puck for my NEMA2000 bus. It gives me a complete backup GPS system for my C80. Sure I have to manually plot position if the C80 craps out, but I'm used to that. I'd like to be able to switch position inputs to my VHF radio but my VHF doesn't do NEMA2000.
I am running a Lowrance NEMA 2000 system (lmf 400, lcx111hd, etc.) and it does have wiring for 0183. I never bothered integrating my old gps, though. The manual (you can download it from lowrance) specifies whether 0183 is received or transmitted--it is one or the other and I don't recall. By the way, a Lowrance gps puck is pretty darn cheap. You'll probably do ok if you buy the lmf200 and the puck, plus you'll have some redundancy.
I'll look into the puck for the LMF-200, that does seem like a good idea, but since ltbrett has it on a LowranceNet bus anyway, I don't think it is as simple as hooking up a puck antenna to the LMF-200 and have it work.
Feel free to fill me in on this hookup, I would think the proper GPS would be needed to process the data from the ant, and then transpose to NMEA 2000 data so the gauge could understand it.
Thanks

It's that simple!
If you already have the fuel sensor hooked up to the LMF-200 using the LMF-200/sensor kit and it reads fuel flow, when you open the box containing the puck you will find everything needed (and a little more) to plug the gps puck into the NEMA2000 bus you just created. NOTHING else is needed. Plug it in, lay the puck somewhere topside, tell the LMF-200 it has a new device and like magic everything works.
Oh it might take you a few minutes to get the first "fix" but the only difference between a LowranceNet and a NMEA2000 net is the little decal and the proprietary Lowrance plugs and sockets. Even the wires are color coded the same.

LOL! No, ScottK, it ain't that simple. You need the Lowrance LGC-2000 which is their NMEA2000 compatible puck. Froogle around. I got mine a while back for $149.
I won't go quite that $$ far. I'll stick with GPH for what my simple needs are.
I Froogled the Navman F2100 for as low as $112.00, so that's how I'll go.
MPG would have been nice!
Thanks for all the help THTer's!

I don't think the LMF can be connected to a NMEA 0183 device. The manual says it can only be connected to a NMEA 2000 network.

To quote myself from above, 0183 and 200 don't mix it seems, and no converter is available.

I know price wise it's a tough pill to swallow but the LMF 400 and a Lowrance NMEA 2000 puck seems like a good deal. Why? Because the LMF400 will display a variety of data and if you start with the NMEA 2000 network now there may be other sensors you'll want to add to the system down the road.
Wish I went this route! Anyone want to buy a slightly used Yamaha FMG with 2 sensors??
Is it possible to convert NMEA 2000 to 0183?
