Don’t hesitate to seek professional help if need be! The connector pin-outs are as follows:īe careful not to short out any connector pins while checking voltages or signal levels! Remember, if you don’t know what you are doing then don’t do anything, lest you make things worse. The signaling lines use differential voltages and are shielded from the power pair for improved noise immunity in fact, there are three independent cable shields used on NMEA 2000 cabling. CAN-bus was originally developed by the automotive industry and is also used widely for industrial applications. NMEA 2000 is a single-bus architecture network that is based on Controller-Area Network (CAN) bus technology. Chances are good that it is implemented on board your boat/yacht, so let’s start out by describing some of its technical characteristics. It is the international standard for marine electronics interfacing adopted by the IEC (IEC 61162-3) and is the protocol of choice for AIS products. The NMEA 2000 Marine Network Standard is the key and enabling factor driving the nautical trend to digital networked shipboard electronics into the 21st century. This is due to the rapid and ongoing proliferation of networked electronics, which provide unparalleled monitoring, control, and informational display systems. The modern yacht has more in common with the fictitious Star Ship Enterprise then it has with seagoing vessels of just a decade ago.
