Compact "Plug And Play" Quad band GSM modems can be directly connected to the serial port of a desktop or
notebook computer through the RS232 interface. A standard SIM card can be inserted in the integral card-holder
within the metal enclosure.
The modems' metal casing makes it an appropriate solution for tough industrial applications such as Telemetry,
Wireless Local Loop (payphones) or as part of a fleet management system. The small size makes it simple to
integrate in a space constraint environment. The modem is supplied with power cable. Other accessories available
are an antenna (with 1m coax cable), RS232 connecting cable with Telephone interface, DIN Rail mounting adaptor
and power supply unit.
About GPRS: GPRS stands for General Packet Radio Services. The user can remain "ON" all the time and the
data communication speed rivals that of a cable modem.
