IoT Products

The rugged D80 Serial to IP 3G Modem  (called DTU as well) is a cellular modem developed especially for M2M applications.

It provides RS232/RS-485/RS-422/TTL interface and supports PPP, TCP/IP and DDP protocol, can convert user data into HSPA+/HSDPA 3G network and transmit data to customer’s data service center through complete transparent data channel, allows a simple and rapid integration of cellular network connectivity into M2M applications.


With 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.
