The Quad-band G-4500 series provided by ICP DAS are M2M (Machine to Machine) mini programmable controller are widely recommended in the market. They are widely applied in various applications like hydrographic monitoring, intelligent power, flow meter report system and GPS car-tracking system. ICP DAS announces the Quad-band G-4500 series to meet the requirements of more customers. Most GSM networks operate in the 900 MHz or 1800 MHz bands. Some countries in the Americas (including Canada and the United States) use the 850 MHz and 1900 MHz bands because the 900 and 1800 MHz frequency bands were already allocated. However, Quad-band G-4500-2G series is supporting GSM 850/900/1800/1900 MHz more than tri-band G-4500-SIM300 series. They can be achieved that roam the world’s GSM system. In addition, ICP DAS also introduces the Quad-band G-4500 Series of plastic casing.

The G-4500-2G series feature GPRS/GSM module, Ethernet interface, optional GPS module, 3 digital inputs, 3 digital outputs, 8 analog inputs, 2 RS-232 and 1 RS-485 port. That can be used in various application fields to transfer data by GPRS, SMS, Ethernet or serial bus. In traditional application, users need a master controller to integrate a GPRS/GSM modem with developing GPRS or SMS programs into the host. That would waste much time to integrate the various communication interfaces. Now, we have G-4500 series to solve the hardware integration problems with easy-to-used libraries. The G-4500 series built-in MiniOS7 provide the same development environment with I-7188/I-7186 series. It is more easy for I-7188/I-7186 users to apply the G-4500 series.

By using G-4500 series, a machine can be installed virtually anywhere but still be connected to a support centre to signal performance or need for service. M2M data will improve the service quality and reduce operating costs. Many application areas can be improved by using GD-4500-2G.

    Software Solutions

    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.
