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 ca sing 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 accessori es av ailable 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.

z The modem generates radio frequency (RF) power. When using the modem care must be taken on

safety issues related to RF interference as well as regulations of RF equipment.

z Do not use your phone in aircraft, hospitals, petrol stations or in places where using GSM products is

prohibited.

z Be sure that the modem will not be interfering with nearby equipment. For example: pacemakers or

medical equipment. The antenna of the modem should be away from computers, office equipment, home appliance, etc.

z An external antenna must be connected to the modem for proper operation. Only uses approved
