The G-4500 RTU is an intelligent Active GPRS Remote Terminal Unit which is built-in the specified firmware in G-4500 series. Within the high performance CPU, the G-4500 RTU series can handle a large of data and are suit for the hard industrial environment. They 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 ports. That can be used in various application fields to transfer data by GPRS or Ethernet. G-4500 RTU firmware is designed for communicating with Modbus RTU devices and provides active data transmission via GPRS connection. Except for the Modbus RTU’s data, the built-in I/O and GPS data also can be transferred to RTU Center software by the defined period or DI/AI trigger. With the built-in redundancy communication paths of GPRS and Ethernet in G-4500 RTU, the data would be guaranteed to transfer to host. When GPRS or Ethernet connects failed, it will immediately switch to a different connection method in order to achieve data monitoring sustainability. Furthermore, G-4500 RTU provides simple I/O linkage control and the built-in I/O recorders in SD card.
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 G-4500 RTU 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
G-4500 RTU devices with active I/O transmission mechanism can raise the communication. Unlike the traditional poll communication, G-4500 RTU 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.
Redundant communication paths in GPRS and Ethernet
There are GPRS and Ethernet communication interfaces in G-4500 RTU. Through the setting in G-4500 RTU Utility, you can set the primary and backup paths to communicate with M2M RTU Center. When the primary path is failed, G-4500 RTU can use the backup path to communicate to M2M RTU Center to ensure the data can transfer to PC. That can raise the reliability of communication effectively.
Modbus RTU device connectivity
The G-4500 RTU is built-in Modbus RTU protocol. That can make any Modbus RTU device connect to G-4500 RTU. By the way of G-4500 RTU, Modbus RTU devices can be used in GPRS remote system.
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
G-4500 RTU 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 |
