1. Introduction
The GTM-201 series are industrial Quad-band GSM/GPRS modems with
RS-232 and USB interfaces that work on frequencies of GSM 850 MHz,
EGSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz. The modems utilize
the GSM/GPRS network for convenient and inexpensive data transfer from
remote instruments, meters, computers or control systems in either live or
packet data. GTM-201 series 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
GTM-201, systems can be SMS and GPRS connection applications with
various PLC and PC's. With the voice interface, these modems can also be
applied to alarm systems with sounds.
