Just got mine back today. No questions asked. I never talked to anyone at Lowrance. I went to their website, obtained an RA number, explained the problem to them and sent it in. Less than two weeks, they sent a whole new unit and sender. So if anyone would like to buy a LMF 200, display only, brand new, I will give you a good price. I'm keeping the EP60!

i finally got the boat in the water this past weekend. i have one of my three EP's sent back and a new one coming. when trying the two and the LMF-400, only one EP worked. the 400 recognized both but only one had a fuel flow reading. now i guess i have to get back in touch with Lowrance and see what they say this time.
when you used the RA request on Lowrance's site, what choices did you make on the troubleshooter? it appears to be for sonar and/or GPS only. i may try that over calling again.
thanks
Lowrance called me today after having the unit for two weeks (i tracked it) and was told the unit works fine, they are sending it back. He then said it is either the T's or the sensors, most likely the sensors. I quietly challenged them on all the trouble there is out there with these things and asked if they would send three new sensors back with italong with new T's. He said he would, then hung up, we shall see.
i got the replacement EP60R yesterday with a new Tee. the Tee and connector is black with a black connector on the EP. Lowrance did send instructions on how to get the EP with a zero reading to work earlier from a question i asked. i'll try that and then install the replacement EP. if the new EP works i guess i'll try the RA again with the one reading zero.
The force is not with me on this project. I finally got my replacement EP-60 a few days ago and it works.
I ordered a EP-65 at the same time, but the box I got contains only an extension cable for a totally different system. Another round of returns, great .....
Hi Everyone,
I just installed a new LMF 200 with EP-60R and I am having the same problem. It worked initially, then I unconfigured it, and now all I get is the No Device On Bus message. What the final solution here? All of my T's are all black and the the network connectors are either black or red.
Send it back I guess...??
All the posts on this thread came to a screeching halt last May, it looks like. Did everyones' problems with losing the EP-60R off the bus get fixed?
If so, please post what the solution to this is. My LMF-200 with EP-60R worked fine for over a year and then, while cruising along in the middle of a trip, the FF stopped and instead of numbers I get "--" flashing. Once home I went through resets, hard and also by choosing "reset" on the sys setup menu. The LMF-200 is not seeing the EP-60R.
I've unplugged all the connectors and connected them back up. I've done all the obvious things, including calling Lowrance three times. The only knowledgable-sounding person I talked with of the three calls ruined his credibility by arguing with me that the EP-10 looks exactly like the EP-60R except for the color of the connectors. Unless I'm very mistaken, the EP-10 was long and skinny and the EP-60R is boxy. Both are very different in appearance - no possibility of mixing them up. Yet this fellow was certain they looked the same. And this was the best of the bunch. Their only "help" was to recommend I buy a new sensor - however I'm concerned that it may be a problem with something other than the sensor since the control unit cannot see it on the bus.
Is there a software upgrade for the LMF-200 and, if so, how does one do the upgrade? Send it in to Lowrance? I read somewhere in researching this problem that they've upgraded the software for the LMF-200.
Anyway, I was doing nothing when it quit. Not touching anything.
I installed the lmf-200 with the ep-10 unit. It worked for one or two trips out then started acting up weird. Called lowrance and they said its my ep-10 sensor. They sent out a new ep-60R sensor and a adaptor cable for me. Reconfigured everything back in and everything is now good.
The EP-10's were apparently bad news. I had to wait three or four months after ordering my LMF-200 since the EP-10's were on their way out and the EP-60R's were not in stock yet.
My set up worked fine for almost two years until this sudden problem which occurred for no apparent reason. If I was sure the sensor was bad I could fix things with a new sensor, but I'm afraid of wasting the money since it may be connectors or control head or one of the "T's". Don't know.
Some guru from West Marine was supposed to call me back but never did.
Lowrance products are fine when they work but when you have trouble and you are beyond the warranty period, nobody wants to hear about it. "Buy a new one." is what I hear. Right.
I think I'd go with a Navman if I do buy a new one.
Anyway, I'm still fiddling with this thing. If anybody has gone through this I'd sure like to hear what you did.
once you unconfigure them they are toast. Throw them away because the bus will never see them again. The ep's have a chip in them to record total fuel burned and once you unconfigure it its over... thats why they gave you new ones. if you get the right person on the phone they will admit it .
In my case I didn't unconfigure anything . . . until after it stopped reading out, at which point I tried everything. Re-configure, re-set, etc. I was just flying along when it just stopped working.
When this happens, is it the EP-60R or is it the LMF-200 that fails?
If I knew that I might consider replacing one or the other instead of buying an all-new unit. If I do that I'll probably just buy a Navman.
alright so i recently had the same issue with the LMF-400 not showing all the bus devices. It was an easy fix. Just go in to the bus devices that are shown and unconfigure them. then refresh your bus list and you should see all the devices so reconfigure them.
At first I used a small (4Ah) sealed lead battery. This worked well for an hour or two, until I tried that stupid unconfigure function(to me, this is the strangest part).
Later I have tried a regular 60Ah battery and a high quality lab supply (tried 12, 13and 15V)
What I meant to say was that there is no noticable drop.
I've measured at the terminals using a digital multimeter. I didn't want to cut the cables to mesure other places. Anyway, I can't imagine a short cable like that and low currents would cause a >2Volt drop.
I've refreshed MANY times. It seems strange that something like this would just break under normal use, but right now I can't think of any other explaination.
I think I'll try to find a working network that I can connect my stuff to.
If you look a the diagram that is supplied with the unit you will see the power cable gets plugged into the same part as the display therefore you need a 3rd 3 way connecter that is not included in the kit.
If you do happen to unconfigure a flow meter, there is a way to get it back...you will need something a little more than the LMF series gauge. I had a similar issue and hooked my EP-60R to my HDS5 when I got it, and after some digging, was able to find the sensor. It seems the "unconfigure" function of the LMF200/400 sets the address of the sensor to 255. The LMF is not able to see devices above a certain address (be willing to bet it is 32) and I guess Lowrance thought it would be a good idea to be able to stop communication with one of these sensors. NMEA 2K is still serial communication; hence the end of line resistors. I was able to use the HDS to write to the address of the sensor and set it to "1," which the LMF could "see." If anyone needs any more info, I can try and get some screenshots of what I'm talking about.
Please send some screenshots if you can or describe the procedure step-by-step. I'm stuck with two "nonexisting" EP60s and a LMF-400.
The importer of Lowrance here in Finland completely ignores any requests for assistance and will not even answer e-mails, "buy a new one" seems to be the widely accepted solution.
I'm abslolutely positively sure the one time was the only time i purchased anything made by this company and I will do my best to see to it that no-one i know does the same mistake. It's quite worrying that a company that manufactures navigational equipment has "bugs" of this caliber in the firmware of their products and do not acknowledge it or even try to correct it, just to save a few bucks they "have never heard" of such a problem... I'd never feel safe having to rely on a Lowrance -produced plotter or even echo-sounder just because of their attitude to this EP60/LMF* -problem.
