The Quad-band G-4500 series provided by ICP DAS are M2M (Machine to Machine) mini programmable controllers. They are widely recommended in the market, and widely applied in various applications like hydrographic monitoring, intelligent power, flow meter report systems and GPS car-tracking systems. ICP DAS created 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, the Quad-band G-4500-2G series supports GSM 850/900/1800/1900 MHz, more than the tri-band G-4500-SIM300 series. They can roam the world's GSM system. In addition, ICP DAS also introduced the Quad-band G-4500 Series with plastic casing.
The G-4500-2G series features a 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. This can be used in various application fields to transfer data by GPRS, SMS, Ethernet or serial bus. In traditional applications, users need a master controller to integrate a GPRS/GSM modem with developing GPRS or SMS programs into the host. This would waste a lot of time to integrate the various communication interfaces. Now, we have the G-4500 series to solve the hardware integration problems with easy-to-use libraries. The G-4500 series's built-in MiniOS7 provides the same development environment with the 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 for 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.
