Messenger is an electronic monitoring system with real-time, visual feedback on engine operating conditions. The Messenger display system is designed for use with electronically controlled Caterpillar marine propulsion engines that have J1939 data link support. Messenger’s purpose is to display current engine and transmission data, trip data, historical data, and diagnostic information. It may also interface with vessel global positioning systems to display vessel position and speed. The Messenger system displays all of the available information on a graphical LCD (Liquid Crystal Display). The Messenger display uses transflective LCD technology along with the existing SAE J1939 data link to provide real-time performance and operating information.
