The rugged D80-1 series serial to IP GPRS/EDGE modem (called DTU as well) is a cellular modem have been developed especially for M2M application. It provides RS232/RS-485/RS-422/ TTL interface and equipped with PPP, TCP/IP and DDP protocol, it could convert the user data into EDGE or GPRS network and transmits the data to the customer’s data service center through complete transparent data channel, allows a simple and rapid integration of cellular network connectivity into M2M application. With the robust, reliable, long life and compact metal case design, the D80 DTU ideally adapts to onboard standard, easy to deploy and maintenance, it has been widely applied in many fields worldwide, such as power SCADA, oil field, coal mine, weather forecast, environment protection, water conservancy, heating, natural gas, petroleum and so on.
