The Simrad autopilot uses “Simnet,” which is really N2K, so interfacing that is just a matter of wire cutters and field-attachable connectors. Scattered around the ship are sensors, instrument displays, chartplotters, an autopilot, engine interface, and even a two-layer gateway that lets the ancient B&G network sensors get translated to NMEA 0183 and thence to N2K. The first is off-the-shelf NMEA 2000 equipment (hereinafter called N2K) that is interconnected by a Maretron backbone, and available to the server via a USB interface. I’m basically thinking of this in two major zones. So with all that out of the way, and recognizing the handwriting on the wall, it is time to move forward with the ship systems. Besides, as I said, it really is good stuff, and there is much to be said for standardization and interoperability without a long shake-out period (remember S-100?) For an old geek like me, this seems self-serving in a very destructive sense, but there’s enough momentum in the industry that it will stick anyway. This discourages hobbyists, and even those who do come up with something clever at the network level are prevented from going public. What is more frustrating is that it is not really an open standard (as are the various layers that make up the Internet), so the cost of entry is high and there are substantial legal disincentives to hack, reverse engineer, productize, or even publish without paying to be in the club. This is annoying, but easy to fix once you know the game. All the latest marine equipment is designed to work with this, though some vendors still insist on forcing people to buy their own connectors and cables (going so far as to give their flavor of the standard a distinctive name to discourage shopping around).
There can be lots of talkers, it’s faster, it’s electrically robust, it carries power to all but the thirstiest loads, and it can even be hot-plugged. NMEA 2000, the new stuff, is based on the well-established industrial CAN (Controller Area Network), and is technically far superior to the vintage 0183 protocol.

The old marine “networking” standard (NMEA 0183) was little more than glorified 4800 baud serial datacomm, with various vendors producing their own variants to jockey for competitive advantage. Reads NMEA2000 data and transmits it wirelessly over 802.I have mixed feelings about this, but there’s really no choice.Wireless NMEA2000 Data server (NMEA2000 Certification Pending).

Using standard NMEA data formats, NavLink is compatible with all software applications that support TCP (single device) or UDP (multiple devices) data transfer.Ī number of Marine Navigation software packages support TCP/UDP data transfer including SmarterTrack (PC) OpenCPN (PC/Mac/Linux) SeaPro (PC) Rose Point Coastal Explorer (PC) MaxSea (PC) and Nobeltec (PC) MacENC (Macs) iNavX (iPhone/iPad) Nav Apps: iSailor and iRegatta. NavLink is a simple and cost effective wireless device that converts NMEA2000 data into a wireless data feed that can be received by any mobile wireless device. With more and more equipment now using NMEA 2000 networking, being able to easily connect the network data to mobile devices such as smart phones, tablets and laptops is becoming an important consideration.
