GPRS Telemetry Data Terminal Unit v220

The GPRS Telemetry Data Terminal Unit is a wireless data transfer unit that embedded with High reliable ARM9 MCU and industrial GPRS Engine inside. The GPRS DTU is special for transparent transferring data between RS232 port and internet over GPRS wireless network. The GPRS wireless communication has become widely used of industrials and utilities and many customers are requiring reliable, flexible and cost-effective data channel to build their information system. Many applications such as Remote device monitoring, remote automatic metering system, ATM, data logging system, POS, SCADA and surveillance system will require data channels covered all country. GPRS DTU is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry. Meanwhile, it is supplied with simple and user friendly PC Configurator to configuration, easy to installation. How Does the GPRS DTU works? The GPRS DTU with dynamic IP address, if you want to create the connection between the server and GPRS DTU, must using call, SMS or Com port to activate the GPRS DTU firstly. Then the GPRS DTU will create the connection to the Server to build the tunnel, so the server can communicate to the GPRS DTU. The GPRS DTU with the heartbeat, it can keep the connection tunnel online all the time. Once the connection disconnected, the GPRS DTU will auto redial to create the connection. The server must with static IP address or DNS. Under TCP/ UDP mode, when the data length exceeds a fixed length or within the fixed time no new data received, the GPRS DTU will start to process the received data, packing the data then send to the specified IP address and Port or DNS and Port. Or unpack the data packets from the internet then transfer to the com port according to the baud rate. Functions & Features of the GPRS DTU: 1. GPRS Data Transmission, no distance limitation; 2.
