The G-4500 series provided by ICP DAS are M2M (Machine to Machine) mini programmable controller are widely recommended in the world. They are widely applied in various applications like hydrographic monitoring, intelligent power, flow meter report system and GPS car-tracking system. The G-4500 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.

Therefore, the G-4500 series applications can be divided into 2 parts: One part is the fixed intelligent remote management equipment such as water monitor system, vending machine system, remote machine monitor, home security, POS system, power measurement system and etc. Another kind of application is movement management equipment such as vehicle management system, maritime system, taxi dispatch system, and etc.
