Introduction
The GV300CAN is a compact GPS tracker designed for a wide variety of vehicle tracking
applications. It has multiple digital/analog I/O interfaces that can be used for monitoring or
controlling external devices. At the same time, it has integrated CAN and J1708 which decodes
information from vehicles digital buses (CANbus and J1708).It also includes a 1-wire interface
used for driver ID and temperature monitoring. Its built-in GPS receiver has superior sensitivity
and fast time to first fix. Its dual band GPRSsubsystem supports 850/1900 MHz
allowing the GV300CAN's location to be monitored in real time or periodically tracked by a
backend server and mobile devices. Its built-in 3-axis accelerometer allows motion detection and
extends battery life through sophisticated power management algorithms. System integration is
straightforward as complete documentation is provided for the full featured @Track protocol. The
@Track protocol supports a wide variety of reports including emergency, geo-fence boundary
crossings, driving behavior, low battery and scheduled GPS position.
