Maretron RIM & SIM, on the N2K frontier
While these screenshots (click’em for full size) are spectacular examples of what Maretron’s new system monitors can do, they are also a bit deceptive. That’s because the underlying sensor technology can scale to much more modest yachts, which don’t need a PC monitoring program like N2KView to use it. For instance the RIM100, or Run Indicator Module, is a little black box that can watch up to six AC or DC circuits, like the nav lights above, and report whether current is running through them, via standard NMEA 2000 messages…
Hence one RIM100–which retails for $299–could mind, say, three nav lights, two bilge pumps, and one engine room blower, and could prompt related info and alarms on any networked screen that’s programmed to display them. A Garmin GMI 10 or Raymarine ST70 could conceivably do the sort of detailed bilge pump cycle analysis we saw in the Blue Sea VSM 422. I’m being quite hypothetical here—heck, I’m not even sure Maretron’s own displays understand circuit run state PGNs yet—but I believe it’s just a matter of programming.
The SIM100, or Switch Indicator Module, is related and possibly even more powerful. As you’ll see, Maretron is even providing optional smoke/heat, high bilge, and motion sensors, though the SIM will purportedly mind up to six switches of most any sort, and in some cases will even know if the underlying circuit is functional. Again, at the moment the only monitoring display system that will definitely work with the SIM is N2KView, but the messages are standard, and therefore aren’t the possibilities unlimited?
