GV55W User Manual 1.Introduction

(Time fast TTFF to First Fix) and supports Dual-Band GSM GV55W is a powerful GPS locator designed for vehicle or asset tracking. It has superior receiver sensitivity, frequencies 850/1900, its location can be monitored in real time or periodically tracked by a backend server or other specified terminals. GV55W has multiple input/output interfaces that can be used for monitoring or controlling external devices. Based on the integrated @Track protocol, the GV55W can communicate with a backend server through the GPRS network to transfer reports of emergency, geo-fence boundary crossings, low backup battery or scheduled GPS position as well as many other useful functions. Users can also use GV55W to monitor the status of a vehicle and control the vehicle by its external relay output. System Integrators can easily set up their tracking systems based on the full-featured @Track protocol. 1.1. Reference Table 1. GV55W Protocol Reference SN Document name
