NMEA 2000 - N2K

Rossjo, just for you... And for you Paul, its closer, not bigger

So, here is a better picture of what I'm currently monitoring.

There is an option to monitor N2K messages and do alarms, but I have not yet configured this option yet. I'll keep you posted when I have time to get that going.

Love it. You're a politician (hope that wasn't an insult) - I suppose you do you need to run to be King.

That setup is awesome - does it record His and Lows as well?

Connected to your Flo-Scans as well? Nice!

Last comment (let me be 1st) - 70PSI Oil Pressure @ 900RPM?

The PSI is pretty close. I run 40W oil and took this picture about 10 seconds after start-up. After about 5 min, she settles down around 40. I do need to do a little bit more calibrating though.

Software in the Lowrance display does not record highs and lows. I also need to do a software upgrade on the displays apparently to allow more "alarms" Hopefully, I'll get some more time this weekend or next.

I like it.

Did you varify pressure with a mechanical gause at engine?

Just back from another two day NMEA 2000/electronics lecture, and I must say some of the stuff coming out on the market is pretty impressive. Amazing what you can do or have your boat do from an iPad/Phone remotely. We're pretty much limited by our imagination. More and more coming out for converting existing analog outputs from current sensors to digital for interfacing to new NMEA 2000 devices/monitors. More manufacturers are recognizing the need to display analog engine functions such as those on our older engines, and tank sensors etc. The big thing now is remote connectivity and networking. Pretty amazing stuff. How about turning on the air conditioner in your boat while you're driving to it!! Or being notified on your phone of a high bilge water condition. I mean you name it. With the controllers, switches and sensors available today, you can put together just about anything you want to monitor or control equipment on board. With its popularity though, a lot of manufacturers are marketing their product as "Works with NMEA 2000" or "NMEA 2000 Compatible". Unless the manufacturer is NMEA 2000 Compliant, and has done due process with NMEA following their script for which they must pay big bucks for, there is no guaranty of compatibility and will most likely create subtle faults that will have you chasing ghosts. You can check to see if the manufacturer of a piece of equipment is truewly compliant by going to the NMEA web site

I love this stuff. Makes you realize just how much the industry is changing to accomodate what the modern consumer wants, and that if you're in the business, you better keep up or you'll be left behind.

Good info

I should mention Paul that there are now converters for anybody running J1939 networked engines and generators so you can monitor those systems on today's new displays. We've had a couple of older deisels converted. Nothing changed on the actual engines, just converted the J1939 data to digital NMEA 2000. Some people like all the gages and switches, these guys had helms with two screens, that's it, no gages no switches. Any switching and readings was done off the screens. Very clean helms, no clutter. Not my style but it's impressive to see everything controlled from vitual switches on a couple of screens. We may as well get used to it, it's here to stay. I see Furuno has gone touch screen now, something they said they would never do! It's a very nice display that you can manipulate with two fingers like a phone or iPad. No more need to push a button to zoon in or out, you simply use your thumb and index finger, cool stuff. Like I said before, it's the consumer that drives the product, not the manufacturer.

It is amazing for sure , Now is the could come up with a diesel "flow scan "type unit that costs a few hundred

If you had a NMEA 2000 network already installed, Maretron sells fuel flow monitors for deisels up to 3000 HP that hooks right into the system and displayed on compatible monitors. These things have temp sensors embedded in the meters for temp compensation due to higher temps of returning fuel. Without this type of compensation, your readings of fuel consumption can be off as much as 5%. They will also account for reverse fuel flow due to fluctuating pressure caused by the injection pump. You also don't need additional external hardware that you need with other brands to condition the flow like straighteners and pulsation dampers. There are also water and oil flow sensors that can be connected to the same control box. And once you have this data, you can do anything you want with it, even chart comparison a flow to rpm, with trim tab position, vessel attitude, speed etc, and record it all. They're even coming out with a "Black Box" (it'll actually be orange) that records all monitored data that you can download to a stick and check it all out on a computer for diagnosing a problem of just keep it as a log. Wish I won the loto

Even with NMEA 2000 network , its $395 per sensor and you need 2 sensors per engine . and then you need to have the corect software am I correct on this ?. Not to simple or cheap to me . I belive some of my stuff is NMEA 2000 but will have to recheck .

what would it take to do a stand alone fuel system ?

Not a cheap endeavour for sure. Unless you are very well off, doing a complete retrofit at once is beyond the average boater's ability cost wise. But there are a lot of average boaters with the insight to start with the very basics; a backbone and display, and add a sensor or two every year. That's part of the whole idea and what makes NMEA 2K so versatile and easy. It doesn't get any easier than a one cable install throughout the entire boat to which all other sensors hook up to.

In the case of Maretron, you would need the Fuel/Fluid Flow Monitor FFM100 controller, and the sensors. You do not need special Maretron software unless you want to get real creative with the data on a computer, internet, switching etc etc. The only thing you need to assure is that your current NMEA 2K compliant display will handle flow data. If it doesn't at present, it's usually a simple matter of a software upgrade download from the OEM. That's why software upgrades are so prevalent these days, more and more hardware/accessories keep hitting the market. If you have a Furuno Paul with a telephone type network jack/cable, that is pre NMEA 2K tech.

Not really spot on topic, but a cool thing about some of the new electronics... The Garmin 4200/5200 series has a 15 pin monitor plug on the back of the MFD. Buy a $150 monitor, and an 8' cable, and you can have a large repeater screen that can easily be seen all the way from the back of the cockpit.

Nice when your fishing or whatever, and someone else is piloting.

Big D I have a Koden set up and some older garman

the backbone is the main thing working on that now have most of the upper helm done starting the lower one now, putting a HDS 5 in place as a lower repeater and then on to the engine room and flow sensors ...temp, pressure etc...NEMA is some great stuff...but some of the things are just toys..like kicking in the AC if you've got the funds for it great....but it's a toy. know what I mean now the bilge and anchor alarm app for your phone that's nice..
