UK-based Actisense, using their knowledge of NMEA product designs, unveils its EMU-1 electronic engine monitoring unit. The demand for greater speed and the ability to share information across a greater volume of instruments led to the development of the newer NMEA 2000 standard which has been developed to supersede the NMEA 0183 serial data bus. This standard is able to connect various instruments along a single backbone, allowing one display unit to show many different types of information.
