Description

The dual band EGSM900/1800MHz GM29,is a GSM/GPRS serial modem. The modem is a powerfuland flexibledevicethat can be used in a wide range of telemetry and telematics applicationsthatrely on theremoteexchange of data,voice,SMS or faxes via the GSM cellular network.

Small and lightweight, the GM29 has standard connectors and an integral SIM card reader makingit easyandquickto integrate.Aswella s providinga standard RS232 serial communicationinterfacetheGM29 alsohas an audiointerfaceallowing an analoguehandset to be connected. When the GM29 is integrated into an external application, a wireless communicaions system is created.

A typicalend-to-end systemconsists of a micro controller in an external application communicating, via the GM29 modem, with a remote terminal or host using the GSM network.The micro controller uses a set of AT commands to control the modem, and to set up the end-to-end communicationslink, via its 9-way RS232 serial interface.

GM29serial modemsare intendedto be usedby manufacturers, system integrators, application developers and developers of a wide range of equipment and business solutions,typicallyin the following fields:

• Security and alarms

• V ending

• Monitoring and control

• Utilities

• Fleet Management SimplyconnecttheGM29intoyour application

as described later in this guide.

Safety and Installation Information

[Needs to be checked and re-written]

• TheTerminal should be installed and setup only by qualified personnel.

• Connect a fast 1.25A fuse to the incoming line for the positive supply voltage to protectthe Terminal.

• If a power supply unit is used to supply the GM29 modem, it must meet the demands placed on SELV circuits in accordance with EN60950. When using batteries and accumulators,adhere to the relevant regulations.

• The maximum permissible connection length between the GM29 Modem and the supply source is 3m.

• Your supplier will be pleased to provide you with a detailed technical description and technical support for the GM29 Modem.

Securing the Modem

NOTE! Before securing t he modem take into

accountthe amountof additionalspace requiredfor the mating connectorsand cables that will be used in the application.

NOTE! Where access is restricted, it may be

easierto connect all the cables to the modem prior to securing it in the application.

Securely attach the GM29 modem to t he host application using two 3mm diameter pan-head screws of appropriate length as shown below.

CAUTION! Do not over tighten the fixings

screws. Excessive torque applied to the screws can crack the plastic case.

Electrical Connections

All electrical connections to the GM29 are protectedin compliance with the standard air (4 kV) and contact (8 kV) discharge ESD tests, of EN 301 489-1.

The modem uses the following industry standardconnectors:

• RJ11 6-way (power connector)

• RJ9 4-way (audio connector)

• SIM card reader

• FME male coaxial jack (antenna connector)

• Sub-D socket, 9 pin (RS232 serialport)

Power Connector

An RJ11 6-way connector, as shown and describedbelow, serves as a means of supplying and controlling d.c. power to the modem.

Connectpositivepower to VCC (pin 1) and the ground or negative to GND (pin 6). VCC and GND are reverse polarity and overvoltage protected

NOTE! Application of the supply voltage

VCC, does not automaticallyswitch on the modem.

Switch on is usually achieved by use of the TO_IN signal, which can be supplied by the host application. Alternatively t he modem can be switched on at the same time that power is appliedbyhard-wiringTO_INtoVCC.Refer to “Switching On the Modem” on page 10 for information on switch on methods.

Similarlythe host application can be designed toswitchofftheGM29or performahardreboot of the modem's software by use of the HR_IN signal.Refer to “Switching Off the Modem” and “Resetting the Modem” on page 10 for additional information.

TO_IN and HR_IN are referenced to GND.
