1. INTRODUCTION
1. Introduction
1.1 Description
The dual band EGSM 900/1800MHz GM29 is a GSM/GPRS serial
modem. The modem is a powerful and flexible device that can be used
in a wide range of telemetry and telematics applications that rely on the
remote exchange 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 making it easy and quick to integrate. As well
as providing a standard RS232 serial communication interface the
GM29 also has an audio interface allowing an analogue handset to be
connected. When the GM29 is integrated into an external application, a
wireless communicaions system is created.
A typical end-to-end system consists 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
communications link, via its 9-way RS232 serial interface.
GM29 serial modems are intended to be used by manufacturers, system
integrators, application developers and developers of a wide range of
equipment and business solutions, typically in the following fields:
• Security and alarms
• Vending
• Monitoring and control
• Utilities
• Fleet Management

1.3.7 Serial Communication
The GM29 enables an end-to-end communication path to be established
between the external telemetry/telematics application and a remote
terminal or host, via the GSM network. Once a path has been set up,
voice or data communication can take place. Serial data with flow
control according to the RS232 signalling protocol operates between the
modem and the external application.
Control of the GM29 is by the external application, via the RS232 serial
interface, using a set of AT commands. The GM29 supports the full set
of AT commands according to GSM 07.05 and GSM 07.07. It also
supports an extended set of Ericsson proprietary AT commands to add
extra functionality.
AT commands are used to operate the modem and have a broad range
of functions including:
• configuring general parameters of the GM29;
• setting up and controlling communications to and from the GSM
network;
• configuring the modem to communicate across the RS232 serial
interface;
• and obtaining GSM network status information.
For more detail on the AT commands supported by the GM29 see “AT
Command Summary”, page 27.

3. ELECTRICAL DESCRIPTION
3. Electrical Description
All electrical connections to the GM29 are protected in compliance with
the standard air (4kV) and contact (8kV) discharge ESD tests, of
EN 301 489-1.
The modem uses the following industry standard connectors:
• RJ11 6-way (power connector)
• RJ9 4-way (handset connector)
• SIM card reader
• FME male coaxial jack (antenna connector)
• Sub-D socket, 9 pin (RS232 serial port)
3.1 Power Connector
An RJ11 6-way connector, as shown and described below, serves as a
means of supplying and controlling d.c. power to the modem.
The supply voltage,VCC, required by the modem is in the range 5V 32V d.c. Application of the supply voltage does not switch the modem
on. To do so an additional active-high control signal, TO_IN, must be
applied for > 0.2s.
A second active-high control signal, HR_IN, can be used to switch the
modem off when applied for 1 - 2 seconds, or can be used to perform a
hardware reset when applied for > 3.5s.
TO_IN and HR_IN are referenced to GND (pin 6 on the connector).
VCC and GND are reverse polarity and overvoltage protected.

3. ELECTRICAL DESCRIPTION
3.5.1 Serial Data
The modem supports the standard data character format of 1 start bit,
8 bit data, no parity plus 1 stop bit, in total 10 bits per character.
3.5.2 Serial Data Signals - RD, TD
The default baud rate is 9.6kbps, however higher bit rates up to 460kbps
are supported and can be set by AT commands. At start-up the GM29
transmits and receives data at the default rate of 9.6kbps in either
standard AT mode or binary mode (the first received data - AT or binary
format - determines the operating mode).
Serial Data From Modem (RD)
RD is an output signal that the modem uses to send data to the
application.
Serial Data To Modem (TD)
TD is an input signal, used by the application to send data to the modem.
3.5.3 Control Signals - RTS, CTS, DTR, DSR, DCD, RI
RTS and CTS are capable of transmitting at 1/10th of the data
transmission speed for data rates up to 460kbps (byte-oriented flow
control mechanism).
Request to Send (RTS)
Used to condition the DCE for data transmission. The default level is
high by internal pull up.
The exact behaviour of RTS is defined by an AT command. Software
or hardware control can be selected. Hardware flow is the default
control.
The application must pull RTS low to communicate with the modem.
The modem will respond by asserting CTS low, indicating it is ready for
communication.
Clear To Send (CTS)
CTS indicates that the DCE is ready to transmit data. The default level
is high. You can define the exact behaviour of CTS through an AT
command, and can select software or hardware flow control.
19
LZT 123 7359 R1B
GM29 TECHNICAL DESCRIPTION
Data Terminal Ready (DTR)
DTR indicates that the DTE is ready to transmit and receive data. It also
acts as a hardware ‘hang-up’, terminating calls when switched high.
The signal is active low. You can define the exact behaviour of DTR
with an AT command.
Data Set Ready (DSR)
An active DSR signal is sent from the modem to the application (DTE)
to confirm that a communications path has been established. DSR has
two modes of operation, settable using the AT command AT&S.
Data Carrier Detect (DCD)
DCD indicates that the DCE is receiving a valid carrier (data signal)
when low. You can define the exact behaviour of DCD with an AT
command.
Ring Indicator (RI)
RI indicates that a ringing signal is being received by the DCE when
low. You can define the exact behaviour or RI with an AT command.
3.6 Real Time Clock
The GM29 contains a real time clock (RTC) to maintain accurate
timekeeping and to enable “timestamping” of messages.
The RTC is powered all the time that the modem is turned on. When the
modem is powered off, a stored energy device within the GM29
provides back-up power to maintain the RTC for at least 7 hours.
3.7 Software Updates
It is possible and sometimes necessary to update the GM29 software.
Updates must be carried out by a Sony Ericsson approved technician.
Please contact your supplier for details (see “Service and Support”,
page 9).

4. OPERATION
4. Operation
4.1 Switching On the Modem
There are two ways to switch on the modem, once power is applied.
• either assert TO_IN high for > 0.2s;
• or activate the RS232 control line DTR, high for > 0.2s.
The modem is fully operational after 4 seconds. Logging onto a network
may take longer than this and is outside the control of the modem.
The modem can be configured to start up at the time power is applied
by permanently tying power connector signals TO_IN (pin 4) and VCC
(pin 1) together. In this case DTR must be used to switch the modem on
again after it has been switched off or reset, while power is still applied.
4.2 Switching Off the Modem
There are two ways to switch off the modem as described below:
• either use the appropriate AT command;
• or assert HR_IN high for 1 - 2 seconds. A delay of up to 10s is
experienced as the modem logs off the network.
4.3 Resetting the Modem
A full system reset, independent of the status of the software, may be
applied to the modem as follows:
• assert HR_IN high for > 3.5s.
4.4 Operating States/LED
The modem has a green LED, as depicted below, which is used to
indicate various operating states. These states are described in
following table.

6. AT COMMAND SUMMARY
6. AT Command Summary
The AT standard is a line-oriented command language. AT is an
abbreviation of ATtention and it is always used to start sending a
command line from the terminal equipment (TE) to the terminal adaptor
(TA).
The command line consists of a string of alphanumeric characters. It is
sent to the modem to instruct it to perform the commands specified by
the characters.
As the list of AT commands supported ocassionally changes, it is wise
to check the latest listing with Sony Ericsson before starting any
software development (see “Service and Support”, page 9).
