Features

GT-540 application

GT-540-3GWA is an intelligent Active 3G Remote Terminal Unit. Within the high performance 32 bit CPU, GT-540-3GWA is suit for the hard industrial environment. It features 3G(WCDMA) module, 6 digital inputs, 2 digital outputs, 1 analog input, 1 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 via 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, GT-540-3GWA offers the e-mail mode to transfer the data by e-mail via 3G for users to choose. The simple I/O linkage function of GT-540-3GWA 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, GT-540-3GWA 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 3G and the Internet.

  • Easy to Establish WCDMA/GPRS Network Applications
    It is a big headache for engineers to establish the WCDMA/GPRS applications because the dynamic IP management is required. Applying GT-540-3GWA and M2M RTU center software, the dynamic IP addresses can be managed between them. The remote WCDMA/GPRS RTU product would connect to M2M RTU Center automatically. Therefore, all remote WCDMA/GPRS RTU devices can be managed by s single centralized M2M RTU Center software with a fixed IP address. Moreover, there are M2M API tool and OPC server for engineers to develop the WCDMA/GPRS applications by VB, VC or SCADA development tools conveniently without any IP address management effort.
  • Active data transmission
    GT-540-3GWA with active I/O transmission mechanism can raise the communication. Unlike the traditional poll communication, it would transfer the data by the defined time, DI trigger or AI hi/lo alarm. In addition to improve the way of communication, that can also reduce the AP effort.
  • Transfer data by e-mail
    Expect for the transferring data by the general communication with the M2M RTU center, users can choose the e-mail mode to send these data by e-mail over WCDMA/GPRS in the fixed time.
  • Modbus RTU device connectivity
    GT-540-3GWA is built-in Modbus RTU protocol. That can make any Modbus RTU device connect to GT-540-3GWA. By the way of GT-540-3GWA, Modbus RTU devices can be used in WCDMA/GPRS remote system. The max Modbus RTU device can be connected to GT-540-3GWA is three.
  • Simple Local I/O link Control
    There are I/O built-in WCDMA/GPRS devices of ICP DAS. Therefore, these products can be the WCDMA/GPRS I/O devices. Expect for these local I/O data can be sent to the host PC, the I/O link function of them help users to do the simple control in local field. For example: the DI trigger or high/low AI alarm can driver the DO channel.
  • Built-in I/O Data Logging
    GT-540-3GWA provides an external SD interface. These local I/O and Modbus data are recorded in SD memory card for one day in a single file.
