    The GRP-540M provided by ICP DAS is a 4G gateway for Ethernet, Wi-Fi, serial port, and CAN. With GPS function, the GRP-540M can also be a GPS tracking system. It can be used in M2M application fields to transfer the remote I/O, Modbus data or video of the camera via 4G/3G/2G. Within the high performance CPU, the GRP-540M series can handle a large of data and are suit for the hard industrial environment. The GRP-540M have 4G module, Ethernet interface, Wi-Fi interface, and GPS module.

    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.

    • Easy to Establish GPRS Network Applications
      It is a big headache for engineers to establish the GPRS applications because the dynamic IP management is required. Applying the GT-540 and M2M RTU center software, the dynamic IP addresses can be managed between them. The remote GPRS RTU product would connect to M2M RTU Center automatically. Therefore, all remote GPRS RTU devices can be managed by s single centralized M2M GPRS RTU Center software with a fixed IP address. Moreover, there are M2M API tool and OPC server for engineers to develop the GPRS applications by VB, VC or SCADA development tools conveniently without any IP address management effort.
    • Active data transmission
      The GT-540 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 GPRS in the fixed time.
    • Modbus RTU device connectivity
      The GT-540 is built-in Modbus RTU protocol. That can make any Modbus RTU device connect to the GT-540. By the way of GT-540, Modbus RTU devices can be used in GPRS remote system. The max Modbus RTU device can be connected to the GT-540 is three.
    • Simple Local I/O link Control
      There are I/O built-in GPRS RTU devices of ICP DAS. Therefore, these products can be the 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
      The GT-540 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.
