How To Replace and Improve the Sea Ray Systems Monitor

[Skybolt]

My system monitor is the one with the leds and the test switch

So then it's something like this:

I have this on my boat, for the most part, they are on two different terminal blocks. But yours is in that IPx module and you will need to open that or unplug the cables and figure it out one wire at a time, if it is not labeled.

If I tap off it will both systems still work

Possibly, the signals should be floating until activated then it's either a hard 12v or gnd. depending on which signal. Bilge pumps will be 12v, engine alarms will be gnd activated. So for the RIM you will need to supply the opposite polarity on the adjoining terminal.

Been waiting to do this project for months now, but the DSM410 is nowhere to be found. Everybody is out of stock and no ETA on rstock...

Perhaps they finally figured out they have manufacturing issue and are deciding to fix it.

Got tired of waiting for the DSM410 to finally be back in stock so I managed to borrow a dockmate's USB100 to do the job. Thanks to ttmott's writeup, the job was done in a matter of hours and worked perfectly. A huge det of gratitude to ttmott for doing all the legwork on this!!! Took some time to decipher the alert set delay, clear point and clear delay, but I finally figured them out.


Have a question on setting multiple Alerts/Warnings for the same instance. In this case, my bilge pumps. Both my emergency bilge pumps are set to immediately alarm upon activation. I also have both my regular bilge pumps set to alarm if they're running continuously for more than 3 minutes (call it an early warning system). Curious to know if I can also set up a simple warning on my regular bilge pumps anytime they activate, primarily for the purpose of keeping a count of how many times they activate. Simply put, I want my bilge pumps to warn whenever they activate but also alarm if they're on for more than three minutes. Just want to make sure one won't interfere with the other and the maretron will transition from a warning to an alarm at the 3 minute mark. Will do some testing next time I'm at the boat to see if it transitions..

You can setup these independently of each other and they don't interact with each other. Warning, counter, alarm and run time are all independent of each other.

One thing to note is that each display is where the alarms are stored. If you don't have a display yet, what are you creating alarms with?

Thanks. Tested it yesterday and you are correct. They are independent of one another. I'm temporarily using the USB100 and NK2analyzer on a laptop until the display becomes available..

 

[Skybolt]

Just an FYI, you can run the DSM250 emulator by itself without launching N2KAnalyzer. Configure the emulator with all of your alarms/warnings and then back them up. When you get your new display restore that backup to the new display.

Also you need to leave the display on all of the time if you want your counter etc. to work. I mounted one of my displays in the electric panel and that stays on all of the time just for the alarms.

Thanks for the advice, especially th backup and restore function! For now, I'm just using the laptop when on the boat so I have my alarms when running. Once the displays are installed, I'll be keeping one on 24/7 for the counter to function when off the boat...

Our SM display crapped out circa May of this year, and I'm still pondering solutions. I've tried simple diagnostics and the reset procedures (for the "newer" SM part numbers than what we have), no joy so far. Not unexpected. And in the meantime, I've been trying to memorize what you've done to replace/upgrade.

In the meantime, some info on "simple" replacement is here:
http://clubsearay.com/index.php?thr...vailable-at-marine-max-brick-to-order.110932/

I haven't even put eyes on our bilge interface yet, and haven't tried bypassing existing coax to see if our issue is relatively minor. Not expecting it is...

Anyway, can you describe the physical connections at the RIM100? Are the existing sensor wires all connected to the original bilge interface module with ring terminals on studs? If so, are the Maretron connections using those same ring terminals on RIM100 studs? Off the old, onto the new?

Or...?

Just for follow-up... I finally replaced our Systems Monitor with the new parts. See post #1632 in the 58DB thread, here:

http://clubsearay.com/index.php?threads/58-sedan-bridge-official-thread.90211/page-82#post-1419843

Nowhere near the capability of Tom's improved system, but it checks off another "it's broke" thing from my list.

On the NMEA 2000 buss - look to the future of your boat and where you would like it to evolve to both for what you want to add on the network but to also obsolescence and failures. Almost all marine electronics are using NMEA 2000. Route the NMEA 2000 backbone to accommodate that growth and expansion. For example I routed my backbone cabling from the bridge roof to the helm and put tees there then down through starboard side solon and put a tees there, then to the starboard side of the engine room and installed more tees, then over to the port side, more tees, and up to the circuit breaker panel in the solon where there are more tee interfaces. My boat has evolved to need and use all of these points. Secondly, use a quality NMEA 2000 cable for the backbone; spend the money on that. I think Maretron makes the best cabling for a backbone. Here you can see how mine has evolved and I didn't have to replace any component of the backbone cabling; the backbone is the blue line snaking through the boat.

I have a 2006 52 Sundancer that I want to replace the Systems monitor with the Maretron DSM410. Could you possibly help me with this modification? Thanks

Happy to help.
It seems all of the attached photos and diagrams have been lost throughout this thread. Probably when the server for the web site went through an "upgrade".
So it seems you have a 2006 52DA. Does your vessel still have the Diesel View or has it been upgraded to a Vessel View? I ask because one of the three Smartcraft networks is in play depending.

I still have the Diesel view which I replaced with a new one in 2018. It works but does not show my generator data. The screen is there for oil pressure, water temp, ac volts and battery voltage. I want to replace the systems monitor with the DSM410. I was hoping I could add my nmea2000 backbone under the helm where the junction blocks are located. Any help with information and material list is greatly appreciated. My boat has the QSM11 engines with the Onan gen. Thanks

Interesting on the Generator not showing up. The Diesel View should still show the Generator; Vessel View on the other hand will not.
Regardless, The Sea Ray Systems Monitor has nothing to do with the Smartcraft network (the multi-port boxes with the ten pin connectors under the dash). It is a stand-alone system. The only reason I asked about the Diesel View is to determine if you would like the generator integrated in the NMEA 2000 system and viewable on the Maretron DSM410.
Let's put that aside for a bit and get set up on the Systems Monitor replacement -
The Sea Ray Systems Monitor is two components - the SM Interface Module and SM Display. The SM Module is somewhere in the engine room and obviously the display on the helm. They are interconnected with a Coax data cable and power. On the SM Module is a connector with a bunch of wires; these are the wires from bilge pumps, engine ignition, engine raw water loss, and generator ignition/shutdown. The SM Module will be replaced with a Maretron RIM100; the bilge pump wires and generator ignition/shutdown wires will be landed on the RIM100. The engine ignition wires are no longer required. The display power wires are no longer needed. The coax wire is no longer needed. And, the engine raw water loss wires are not used; in fact, they are not even connected at the engines so were never used.
The Maretron RIM100 to be installed in place of the SM Module is connected to the NMEA 2000 network and powered through the NMEA 2000 network.
The Maretron DSM410 is connected and powered through the NMEA 2000 network.

So, first download the DSM410 and RIM100 manuals and read/understand the concept on how the Maretron system works and is set up / programmed.
Then, find the SM Module and take a look at that and wires. Note that most of the features that Sea Ray show are not used on the SM module.
Here are a couple of diagrams that will help get you started -

Thanks for the pictures. I'm retired now but background is in installing and troubleshooting programmable controls, mostly on plastics machinery, also a licensed electrician. I have had several cruisers over the years and do all my own maintenance and retrofits. I dont want to make mistakes with this and your changeover is very similar to mine. I have followed your post and I need your help and knowledge. Before I install the Rim100 module and fuse block my question is mount it where the old module is in the engine room or under the helm next to the junction blocks? I also want to add the oil pressure, coolant temp, ac voltage and ac frequency on the DSM410.

If you wanted to spend a few more dollars then get a Smartcraft Link which will put the engine data as well as most other data (fuel levels, rudder position, etc) that is on the Smartcraft network on the NEMA 2000 network. Now all of that data is available on the Maretron display as well as any other display on the network.
The RIM 100 and fuse block pretty much needs to be mounted where the old Systems Monitor module is; otherwise, you'd be running a bunch of wires up to the helm if located there. The RIM100 is a discrete switching monitor; it cannot work with analog (variable voltage or amperage) signals.

The display on the SR Systems Monitor had died long ago so I did quite a bit of research then retrofitted the hardware and greatly improved the entire system; All for about the price of the SR display alone. The basic pieces are 1 Maretron DSM410 display module, 1 Maretron RIM100 run indicator module, 1 NEMA 2000 backbone and drop cables, 1 Blue Sea fuse block, and some wire. This is the end result, the wire diagrams, and installation photos. The Maretron DSM410 is an impressive piece of hardware and it's capabilities are far beyond the original Systems Monitor; some of the additional features I've incorporated (the data was already on the NMEA 2000 network) include trim tab position, rudder position, navigational data, engine data, depth transducer data, and much more. But, this post is about the capability for the systems monitor features I set up....
Now, for the systems monitor, I limited the monitoring channels to six as that was the total available with one Maretron RIM100; more RIM100 modules can be added but for my purpose six channels were adequate. With that said to reduce from the nine Sea Ray monitored elements to six channels I combined the three bilge sump pumps to one input using shottky diodes to prevent one pump's "on" signal powering up another pump (see the attached schematic) and eliminated the shower sump as a monitored signal.
So, should one of the monitored systems become "active" (like the generator shutting down unintentionally) the Maretron DSM410 display line item turns red, an audible alarm sounds, and an alert indicator comes on in any of the display's screens. A press of the power button acknowledges the alarm and silences the horn. As an additional important feature an integrated counter and timer records how many times and how long an alarm occurs; this is important should the bilge pumps cycle on and off to keep a water leak at bay this data is available and a component of the alarm. A much improved and superior systems monitor.... Recommend.
The first, second, and third images show the monitor in normal (no faults) mode, one of the three bilge pumps running, and how an alert appears in another screen.
The fourth image is the installation where the original SR monitor system was installed and the installation of the new components in the lazarette.
The fifth image is the NMEA 2000 network under the helm.
And, the sixth and seventh are the wiring diag's.
