Brief

We short name Serial to GPRS Gateway as GPRS DTU IP Modem. And Serial to CDMA Gateway as CDMA DTU IP Modem.
D120 Series rs232 modem enables various kinds of legacy devices with serial port to communicate over cellular network and the Internet easily and freely. It not only works as a cellular modem, but also can construct a smooth "cellular Data Tunnel" between Host and Remote side, ensuring an efficient communication for data transmission and remote device management.
With the selectable RS232/TTL/RS485/RS422 serial port, D120 Series DTU modem is an ideal solution for factory automation, environmental monitoring and remote device management etc. Meanwhile, it is supplied with simple Software interface that streamline application development process, freeing system integrators from dealing with complex communication protocols of GPRS/CDMA and the Internet. Users do not need to change the existing system, saving cost and time for field maintenance, and making it a perfect solution for data transmission.
