The ICPDAS GPRS Module GT-540 is an intelligent Active GPRS Remote Terminal Unit. Within the high performance 32 bit CPU, the GT-540 is suit for the hard industrial environment. It features GPRS/GSM module, 6 digital inputs, 2 digital outputs, 1 analog input, 2 RS-232, 1 RS-485 and SD interface. It can be used in M2M application fields to transfer the local I/O or Modbus device’s data by GPRS by the defined period or DI/AI triggers. The local I/O data can also be stored in the SD card to become a remote data logger. For another communication path, the GT-540 offers the e-mail mode to transfer the data by e-mail via GPRS for users to choose. The simple I/O linkage function of the ICPDAS GPRS Module GT-540 can reach the real time control in local field. It also supports Li-ion battery as another power source when the main power is failed temporarily. Therefore, the GT-540 is an ideal solution for environmental monitoring and remote device management for M2M applications. Meanwhile, it is supplied with easy-to-use API and OPC server Software that streamline application development process, freeing system integrators from dealing with complex communication protocols of GPRS and the Internet.









The M2M RTU center software with friendly Graphic interface is to manage the GPRS RTU products easily. Users can monitor the I/O data and status of GPRS RTU devise by the interface on PC. By using the GPRS RTU API tool and M2M RTU center software, any remote monitoring system can be achieved easily and efficiently. For SCADA system, the M2M.OPC server is provided to connect to SCADA by OPC interface.
