The Messenger is an industrial monitoring system that combines, GPS, GSM, CDMA cellular or satellite modem, Controller Area Network (CAN) bus communication and alarm notification. Enclosed in a Deutsch industrial watertight enclosure, the Messenger is small enough to fit in the palm of your hand. Typical monitored conditions are: diagnostic messages, rpm, engine hours, oil and coolant temperatures and pressures, location, and fuel level. Sample-computed values that are reported include engine service interval and daily run time.
