Product Description


                               F2114 gsm/gprs modem (DTU) with I/O


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, 1ower than 1mA@12VDC. It has compatible digital I/O channel, ADC, input pulse counter and pulse wave output function.

Ideal for M2M fields, smart grid, industrial automation, telemetry, finance, POS, water supply, environment protection, post, weather, etc.
