Introduction Highlights 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.
Installation Securing the Modem Safety and Installation Information NOTE! Before securing the modem take into account the amount of additional space required for the mating connectors and cables that will be used in the application. [Needs to be checked and re-written] • The Terminal 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 protect the Terminal.
Electrical Connections RJ11 Power Connector 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 (audio connector) • SIM card reader • FME male coaxial jack (antenna connector) • Sub-D socket, 9 pin (RS232 serial port) 6 5 Connect positive power to VCC (pin 1) and the ground or negative to GND (pin 6).
Audio Connector Antenna Connector A 4-way RJ9 connector, as shown below, allows a telephone handset to be plugged into the modem, giving access to the microphone and earpiece signals. The connector may also be used to drive other analogue audio sub-systems or devices. Connect a GSM antenna to this port. Single (900 or 1800MHz) or dual band (900/1800MHz) antennas may be used. The modem is fitted with a 50 Ω, FME male coaxial jack. FME Connector The GM29 is configured to work with a range of handsets.
RS232 Serial Port Sub-D 9-pin Connector 6 7 8 9 The modem supports a standard RS232 serial interface (EIA/TIA 574) via its 9 pin Sub-D connector, shown below. 1 2 3 4 5 Link the GM29 to a microcontroller or computer in the host application, via the RS232 serial port. AT commands are used by the host-application software to communicate with the GM29.
SIM Card Reader The GM29 is fitted with a SIM card reader in which 3V and 5V SIM cards will operate. The type of card fitted is automatically detected by the modem. 5. Orientate the SIM card and slide into the holder as shown below; To operate the modem a SIM card must be fitted as follows: 1. Disconnect power to the GM29; 2. Remove the cover panel by applying light downward pressure and sliding outwards as shown below; 3.
Operation Operating States/LED Before the GM29 can be operated the following conditions must apply: • SIM card inserted (with the modem unpowered); • antenna connected; • RS232 port connected to the application computer; • power applied. The GM29 has a green LED, as shown below, used to indicate various operating states. These states are described in the following table. LED Operation is not dependent on a handset being fitted. The type of application will dictate whether a handset is necessary.
Accessories Certification A range of type approved and recommended accessories for the GM29 are available through Sony Ericsson's distribution channels. Tested and certified according to: AT Commands The GM29 is controlled and programmed by means of AT commands. For a complete list and detailed description of each command please refer to the Integrator’s Manual on the CD accompanying this product. Type Approval Troubleshooting Do not attempt to repair a damaged modem.
