Detailed Description
What is a GPRS Serial Gateway Modem? It's an industrial modem with RS232/RS485/TTL interface for wireless M2M solutions. We call it DTU in China, and actually it's a GSM/GPRS RS232/RS485 to Cellular Gateway IP modem. Short name for Serial GPRS Gateway, or RS232 Serial GPRS Gateway.
The GPRS DTU IP Modem is a GSM cellular modem with transparent transmission feature. Working under GSM/GPRS networks.
The GPRS DTU IP modem is a GSM modem rs232 or rs485 port. Also there is TTL interface embedded version.
2.5G mobile communication technology (GPRS) has become widely used of industrials and utilities in recent years and many customers are seeking reliable, flexible and cost-effective data channel to build their information system. Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; this brings a bright future for GPRS data networks applications.Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones.
D120g GPRS M2M modem enables various kinds of legacy devices with serial port to communicate over GPRS network and the Internet easily and freely. It not only works as a GPRS Modem, but also can construct a smooth "GPRS Data Tunnel" between Host End and Remote End, ensuring an efficient communication for data transmission and remote device management. With 1 selectable RS-232/TTL/485 serial port, D120 GPRS M2M modem is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry. Meanwhile, it is supplied with simple software interface that streamline application development process, freeing system integrators from dealing with complex communication protocols of GPRS 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.
