Maretron NMEA 2000 Network and Instruments Installations

Posted on Fri 06 August 2010 in Maretron, NMEA 2000, Projects, Systems - Electronics


There’s a shot of my Maretron DSM250 (in red on block mode) displaying data from my NMEA 200 network I finished roughing in last night (or I guess this morning) about 0200. I’m calling it a rough-in because I still need to go back and secure all the wiring, mount the display and the GPS, etc. but I was to plug it all together, fire it up and it worked right out of the gate!


Here’s a shot of the a “T” installed showing the backbone in blue and the drop cable in grey. The black fitting is a field installed fitting whereas the other two are factory pre-installed fittings. The field installable connector has some pretty small screws and was a tad tricky to line everything up, but that is probably due to my large meat hooks. I was able to do it just fine. The waterproof fitting that goes over it all was very tight and I’m sure it has a great seal.

right now I have the following in my system:

I plan to add a depthspeedtemperature gauge to replace my Standard Horizon DS50 depth only unit, but I’m waiting for Airmar’s DST900 to come out (it’s a year late according to rumor) which has the D/S/T and no moving parts! That will be awesome! For now, I’m going to Magruber the DS50 onto the network and maybe if that works fine I’ll just live with that (hurry up Airmar!). We also want to add a rudder angle indicator. I just haven’t gotten to that yet.

Tonight I’ll secure all the wiring and figure out where the GPS will be placed.
