GT-540P

The GT-540P is an intelligent Active GPRS Remote Terminal Unit with GPS. Within the high performance 32 bit CPU, the GT-540P 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 and GPS data can also be stored in the SD card to become a remote data logger. For another communication path, the GT-540P 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 GT-540P can reach the real time control in the local field. It also supports Li-ion battery as another power source when the main power is failed temporarily. Therefore, the GT-540P is an ideal solution for environmental monitoring, remote device management and vehicle monitoring system 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.
