When I purchased my E38 last year it came with an old Magellan first generation GPS (now removed), a working Garmin GPSMAP180 old style monochrome GPS/Chartplotter using Micro G Charts, as well as a NEXUS wind/depth/speed and instrument server system. Over the winter period I installed a Brookhouse iMux wifi multiplexer, Horizon GX2200 VHF radio, ICOM-M802 HF radio, Actisense NGW-1-STNG NMEA 2000 to 0183 gateway, and finally a Raymarine EVO-100 wheel pilot.

Using the iMux multiplexer I can take NMEA 0183 data from my GPS, GX2200 GPS/DSC/AIS data, NEXUS Server sources and share that data to my chartplotting software OpenCPN or Navionics or iNavx all via wifi on my Samsung Tablet and Panasonic ToughBook. In addition I can send waypoints to the EVO-100 through the Actisense gateway.

It is very unfortunate that so many of the marine suppliers like Raymarine are using proprietary NMEA 2000 protocols that seriously limit easy networking to the use of gateway products like the Actisense.

I could easily have just spent $5000 and replaced all of wind instruments and purchased a new chart plotter from Raymarine or B&G to make the networking easier, but then I would still need to network the NMEA 01083 to the NMEA 2000 Raymarine EV-100.

So here is the schematic of my wiring to connect all of these systems together.

    This is not your father's Oldsmobile! We are using the wireless Vesper AIS as our multiplexer to get all the protocols sorted out and distributed to the various devices.

    I'm not 100% certain, but I don't believe Raymarine is using a proprietary NMEA 2000 protocol. They are using a proprietary cable and connector system to lock you into buying more of their stuff. But I am not an expert.

    Great looking graphic, really drives home how everything is innerconnected.

    i looked at the Vesper XB-6000 AIS but wasn't ready to spend the $595 and have a AIS transponder, but that is a great product too with the multiplexer and wifi feature. You may be right about the Raymarine using NMEA 2000 but it is still a challenge to interface back to legacy NMEA 0183 systems.

    How does all that stuff get along with the M802? I have a somewhat similar network, though most of the pieces are different. I'm getting significant interference from the (Shipmodul) MUX and the SeaTalk bus on the 2,4,6 and 8 Mhz bands. My troubleshooting bag isn't empty yet, but so far nothing has made a difference...

    the IC-M802 requires a GPS source for the DSC. I'm using the GPSMAP180 as the GPS source using the NMEA0183 out. For the GX2200 I'm using the radios internal GPS, but have wired it to the GPSMAP180 as well as a backup GPS source.

    I haven't had any issues of RFI from the iMux, but do have noise issues from some of my new LED light bulbs.
