Industrial Smart Cellular Modem for GSM/GPRS/EDGE/UMTS Networks

Enabling effortless M2M communications solutions that significantly reduce costs, save time and enhance services

:: Introduction

Industrial cellular modem is a rugged smart cellular modem offering state-of-the-art GSM/GPRS/EDGE connectivity for machine to machine (M2M) applications.

Key Features

Control via AT commands (Hayes 3GPP TS 27.007 and 27.005).

GPRS, TCP/IP, SMS, CSD access via AT commands.

Featured SMS Direct mode which can transparently convert serial data to SMS or vice versa without using AT Commands. Verification of incoming Caller ID is implemented to block un-authorized users.

Supports Modbus RTU slave protocol, converts alarm to SMS without using AT commands.

Auto reboot via SMS/Caller ID/Timing.

Remote configuration via SMS.

RS232/RS485 selectable by software, 1DI/1DO.

Six LED indicators provide signal strength (RSSI) and status.

Wide range input voltages from 9 to 36 VDC and extreme operating temperature.

The metal enclosure can be mounted on a DIN-rail or on the wall, also with extra ground screw.

Firmware upgrade via serial interface.

The Industrial series GSM modem HMI has Dial Up Networking and rudimentary routing capability built into the unit.

This makes it possible to program the GSM Modem across the Dial Up connection using TCP/IP Ethernet, to route through the GSM modem to an Ethernet enabled PLC and to program/monitor a serial PLC connected to the HMI using Transparent mode through the HMI.

This last mode requires virtual port emulation software such as Serial-IP, which is available from, to be installed on the host PC. It is also possible to remotely view the HMI screen using VNC and access trend data via the built in FTP server.
