Descripción del producto

The rugged D803 Serial to IP 3G modem  (called DTU as well) is a cellular modem which have been developed especially for M2M application. It provides RS232/RS-485/RS-422/TTL interfaces and equipped with PPP, TCP/IP and DDP protocol, it could convert the user data into IP data and transmit the data to customers data center via HSPA+/HSDPA 3G network in a complete transparent data channel, allows a simple and rapid integration of cellular network connectivity into M2M application.
With 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.
