GV200 User Manual
1. Introduction
The GV200 is a powerful GPS Locator designed for vehicle tracking or asserts tracking. With
superior receiving sensitivity, fast TTFF (Time to First Fix) and Quad-Band GSM frequencies
850/900/1800/1900, its location can be monitored in real time or periodically tracked by a
backend server or other specified terminals. The GV200 has multiple input/output interfaces
which can be used for monitoring or controlling external devices. Based on the integrated
@Track protocol, the GV200 can communicate with a backend server through the
GPRS/GSM network to transfer reports of Emergency, Geo-fence boundary crossings, Lower
Battery or scheduled GPS position along with many other useful functions. Users can also use
GV200 to monitor the status of a vehicle and control the vehicle with its external relay output.
System Integrators can easily setup their tracking systems based on the full-featured @Track
protocol.
