GV200G User Manual

1. Introduction

The GV200G 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 GV200G has multiple
input/output interfaces which can be used for monitoring or controlling external devices.
Based on the integrated @Track protocol, the GV200G 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 GV200G 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.
