About NMEA 2000

NMEA 2000 is an open protocol used by a number of different gauge and systems manufacturers - a combined electrical and data network for communication between marine electronic devices such as depth finders, nautical chart plotters, navigation instruments, engines, tank level sensors, and GPS receivers. This "gateway" benefits you by allowing you to purchase NMEA 2000-compliant devices, such as chart plotters, and show engine data on these devices. The gateway also allows NMEA 2000 devices, such as trim tabs, to be shown on the digital engine gauges. Mercury's MercMonitor - used as a gateway between the SmartCraft proprietary protocol and NMEA 2000-compatible devices - is also compatible with the NMEA 2000 protocol.
