Industrial dual serial port Gateway-Image


The rugged D82 series is the two serial port supported serial to IP 4G data terminal, called DTU( Data Transfer Unit) as well. It provides two RS232/RS-485/RS-422/TTL interface and equipped with PPP, TCP/IP and DDP protocol, it could convert the user serial data into IP data and then transmits the data to the customer's data service center through complete transparent data channel over 4G LTE/3G/GPRS mobile network, FDD-LTE / TDD-LTE 4G 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 D82 data terminal ideally adapts to onboard standard, easy to deploy and maintain, 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.
