These modules utilize the GSM/GPRS network for convenient and inexpensive data transfer from remote instruments, meters, computers or control systems in either live data or packet data. I-8212W have the integrated TCP/IP stack so that even simple controllers with serial communications ports can be connected to the modem without the need for special driver implementation. With the features of I-8212W, the systems can be SMS and GPRS connection applications with our PAC series like iP-8000, WinPAC, LinPAC or XPAC.
