GPRS IP MODEM (DTU)
F2114 GPRS IP MODEM is a kind of cellular terminal device that provides data transfer function by public GPRS network.
It adopts high-powered industrial 32 bits CPU and embedded real time operating system. It supports RS232 and RS485 (or RS422) port that can conveniently and transparently connect one device to a cellular network, allowing you to connect to your existing serial devices with only basic configuration. It has low power consumption states in which the power consumption could be 1ower than 1mA@12VDC. It has compatible digital I/O channel, ADC, input pulse counter and pulse wave output function.
It has been widely used on M2M fields, such as intelligent transportation, smart grid, industrial automation, telemetry, finance, POS, water supply, environment protection, post, weather, and so on.
