Brife Introduction
GST201X is GPRS/GSM Model GPS intelligent terminal (Mobile user terminals) Built-industrial level GPRS/GSM communication module and the newest SIRF-Star III High-sensitivity GPS receiver module positioning, adopts GPRS and SMS Dual-mode communication, terminal run stable and reliable, Function-wide, multi-interface, the terminal can be applied to concrete, rental, logistics, public transport, bus and other fields, but also according to different industries, tailored to different users.

Main Features
1. Small and compact size, and easy to install;
2. Accurate GPS positioning dynamic positioning deviation is less than 5 m;
3. In support of GSM voice, SMS functions, and UDP / TCP protocol communications in state of GPRS;
4. Support GPS data uploading at interval and Rollcall function;
5. Support mute function;
6. Support authorized tapping function;
7. Support protection from high or low level voltage function;
8. Support high, low-level signal detection function;
9. Support the data re-sent from signal dead zone function;
10. Support remotely locking vehicle function;
11. Support emergency alarm function;
12. Support the power-off alarm function;
13. Support the high-voltage under-voltage alarm and alarm functions;
14. Support over speed alarm function;
15. Support parking alarm function;
16. Support illegal door-open, illegal engine-start alarm function;
18. Support mileage statistics;
19. Support Geo-fence alarm;
20. Support fatigue driving alarm;
21. Support SMS for alarm notice;
22. Internal flash memory 16MB: When the GST201X is disconnected to the system (for example, the GPRS signal is weak), the position data will be storing in the flash, and then it will upload again after it reconnect to the system (the GPRS signal is ok).
