Henry, I can answer the second one. No other Maretron stuff is required to use a DSM 410. I have a standalone and use the Yacht Devices gateway. As shown above, the Maretron will read/display any and all data on the NMEA 2K network.
Maretron DSM410 / J2K100 / J1939 Onan programming
- Thread starter ocgrant
- Start date
I'll adhoc
First you must set up the alarms in the main menu to include the anchor watch. I have alarms for bilge pumps, generator fault, anchor watch, and a host of other things. The Maretron system must also be integrated with the GPS data on the boat.
Make the anchor watch one of the active screens.
Once that screen is active and showing press the Enter Key and hold for a couple of seconds - the screen will enter what is called "control mode". Note that Control Mode is used for several things on the DSM.
At the point the anchor is dropped press the Power Key. A popup will come up to check for sure that is the anchor drop location - press yes button.
Then exit the control mode by pressing the "Lights" key.
Now the trigger needs to be set up which is the radial distance in feet from the drop point or you can set the point of reference where you have backed the boat down against the anchor at however it's best to add extra feet. I think I default at 100 feet but have changed it occasionally.
The issue I have is exiting the anchor watch properly and having the darn thing alarming continuously when we leave...
Got go back in Command Mode and remove the active watch...
That reminds me of the alarm and how loud it is - it isn't.... So, to make the anchor watch effective I installed Maretron ALM100 alarm modules in the helm and in the solon. Spending the night on the boat is much nicer knowing the system will alarm and it will wake me up. I still have my trusty Drag Queen on the Ipad running also if things are windy or storms are predicted during the night.

The exact reason I don't even try and use it anymore and why I am getting the Vesper 8000. They have an anchor watch program that runs on your cell and doesn't have to be active to alarm. But man Maretron could have made it a little easier to switch modes.

Henry,
I used a Maretron J2K100 to convert the J1939 to N2K. It plugs into the Nim board that was already in my genset. Used the dsm410 to program and display.

Is the NIM board also feeding the Onan remote, or are they separate bits of hardware?

Replaced with ultrasonic. The lightning strike the boat took almost two years ago now fried all of those sensors. It was far cheaper, easier, and better solution to use the TLM100 Maretron sensors rather than try to find and reinstall the OEM.

Grant - I am surprised you get stable J1939 data without a terminating resistor on the end of the cable that connects to the Maretron unit. Or is the resistor included in the cable assembly?

This is what I used and data seemed to be rock solid.

Simple installation, I like it; by reconnecting W5 on the NIM you put the required 120 ohm load on the NIM side of the cable so that cable must have the other 120 ohm load integrated within it on the other side.
Henry, here's an Onan document that shows placement options for the NIM based on what model gen you have.
Grant, are you seeing generator engine hours on the new setup?

Henry,
I think you typo'ed your gen model is it MDKBL? Anyway here is the accessory sheet from Onan

Grant,
Yes, MDKBL is correct, apparently I have not outgrown my dyslexia...
Talk about a picture being worth a thousand words. I have been trying to get a straight answer on whether my MDKBL had a NIM from Cummins and the local dealer and the answer has been right in front of my face.
Grant, Your NIM has a Smartcraft decal, but the W2 jumper is cut making it a J1939 unit. Was it installed that way, or did you make the jumper conversion?
My interest in connecting the gen to the N2K net was to get the data at the helm. With the apparent ease of installing a second Onan remote panel on the helm, what is the generator specific advantage to adding the DSM410? I see its value for the whole slew of other applications. In a semi related vein, what was the cost difference between the remote control display and J2K100/DSM410?
ALNAV, I was fine with what Grant did with the J2K100 device until I reviewed the document you just supplied above in post #32 that suggests all one needs to do is plug a Onan cable into then NIM with a Devicenet plug on the end to get N2K connectivity. Is the J2K100 necessary, or is the answer it depends on year of gen manufacture as some were built Smartcraft/or J1939 and some are Smartcraft/N2k?

Henry,
If you want just the Onan panel this guy in Canada has them cheap brand new in the box, that where Shaps and I got ours. You will need a cable kit to get it to where you want and maybe the "Y" connector depending on your application if you are not daisey chaining.
https://www.ebay.com/itm/254816319517?ViewItem=&vxp=mtr&item=254816319517
The DSM 410 was added to both program the Onan J1939 to N2k so i could have it on my N2K network and my MFD's as a redundant viewing source. The DSM 410 is really just a great programmer and visualizer for furture N2K add on's that I plan. As you can see I love to tinker so this gives me a whole new ave to play with adding N2K devices. Not to mention Tom is a bad influence...LOL.
I guess the big question is do you have a NIM now or not? Have you poped the cover to see?

Henry, the document I posted is for a kit that supplies both only a J1939 converter; it presupposes you already have a NIM. If you look closely at or blow up Figure 1, the supplied converter is the Maretron J2K100.
I believe older Smartcraft boats (like mine) only came with a NIM as it could be directly connected to the existing SC components. At some point in the early 2010's Mercury stopped supporting CAN connections to Smartcraft other than for engines, DTS and Zeus. Newer VesselView units can read and display generator info only if it comes in over N2K. So, newer Smartcraft boats (and perhaps others) seem to have the NIM+converter setup in place at delivery and show generator info coming in over N2K. One way or another, the J2K100 (or similar J1939 converter) is needed.

From what I can tell and infer, is that if one has the lcd remote, or large lcd on gen display, one has the NIM. I have the same remote that you installed. So it looks like I’m good on that score. But as far as the gen is concerned I think I’m going to use your source, and just add a second remote at the helm. If I can daisy chain off the remote in the salon it will be a snap as the electric panel on the inside of the cabin is literally under the helm.
A DSM is in the future, but no need to add the J2K100. I can tap into either end of the existing N2K network. The DSM display seems to have more flexibility than the Raymarine four inch display that I had been planning to add.
Before I starting spending money I need to get back to the boat and drop the master electrical panel where the gen remote is mounted to check for a pigtail to daisy chain off. And then I’ve got to pull the front panel to double check the NIM situation. I can do the former next week when I go to see how the exterior teak revarnish is progressing. The latter is a bit more involved as bodily contortions will be required.

Got it. The cable in Fig 3 is actually J1939 and goes to the Maretron box input side despite being labeled as N2K in the fig 3 Parts block. I’m pretty sure mine does not have the Maretron box as there is only a wire bundle coming out of the side of the case for the remote. In any event, now knowing the remote can be added means I don’t have to mess with the gen. If I’m lucky I can just daisy chain a second remote of the existing and DSMs can be added anywhere on the N2k network.
Guys, thanks for all the help on this.
