GM29 INTEGRATOR’S MANUAL 2.4 SIM Card Reader The GM29 is fitted with a SIM card reader designed for 3V and 5V SIM cards. It is the flip-up type which is lockable in the horizontal position and is accessed through a removable panel as shown below. The SIM card reader includes a SIM presence switch. This ensures that when a SIM card is inserted or removed while the GM29 is turned ON, it will reset.
2. ELECTRICAL DESCRIPTION 2.5 RS232 Serial Port The modem supports a standard RS232 serial interface (EIA/TIA 574) via its 9 pin Sub-D connector, shown below. In line with serial communication terminology the GM29 serial modem should be considered as the data circuit-terminating equipment (DCE) and the external application or computer as the data terminating equipment (DTE).
GM29 INTEGRATOR’S MANUAL 2.5.1 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. 2.5.2 Serial Data Signals - RD, TD The default baud rate is 9.6kbps, however higher bit rates up to 460kbps are supported. 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).
2. ELECTRICAL 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. The DTR line can also be used to switch on the modem when activated for 0.2 seconds. The DTR line must be deactivated prior to switching off the modem to ensure it switches off (powers down) correctly.
GM29 INTEGRATOR’S MANUAL 3. Operation 3.1 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.
3. OPERATION 3.4 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. LED Notes! Operating State LED Status After switching on the modem On after 4s Switch off (Power down) or power removed Off Standby or talk Flashing No network, network search, no SIM card, no PIN entered On Switch off (Power Down): DC power is applied but the modem is switched OFF.
GM29 INTEGRATOR’S MANUAL 4. Hints for Integrating the Modem This chapter gives you advice and helpful hints on how to integrate the GM29 into your application from a hardware perspective. Please read and consider the information under the following headings before starting your integration work: • Safety advice and precautions. • Installation of the modem. • Antenna. 4.1 Safety Advice and Precautions 4.1.1 General • Always ensure that use of the modem is permitted.
4. HINTS FOR INTEGRATING THE MODEM • When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder. CAUTION: Do not touch these connectors! If you do, you may release an electrical discharge that could damage the modem or the SIM card. • When designing your application, the SIM card’s accessibility should be taken into account. We always recommend that you have the SIM card protected by a PIN code.
GM29 INTEGRATOR’S MANUAL Signal Strength The modem has to be placed in a way that ensures sufficient signal strength. To improve signal strength, the antenna can be moved to another position. Signal strength may depend on how close the modem is to a radio base station. You must ensure that the location at which you intend to use the modem, is within the network coverage area.
4. HINTS FOR INTEGRATING THE MODEM Securing the modem • 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. • Where access is restricted, it may be easier to connect all the cables to the modem prior to securing it in the application. • Securely attach the GM29 modem to the host application using two 3mm diameter pan-head screws of appropriate length as shown below.
GM29 INTEGRATOR’S MANUAL determine whether the antenna needs to be grounded or not. Your local antenna manufacturer might be able to design a special antenna suitable for your the application. 4.3.2 Antenna Type Make sure that you choose the right type of antenna for the modem.
4. HINTS FOR INTEGRATING THE MODEM • Noise can be caused by electronic devices and radio transmitters. • Path-loss occurs as the strength of the received signal steadily decreases in proportion to the distance from the transmitter. • Shadowing is a form of environmental attenuation of radio signals caused by hills, buildings, trees or even vehicles. This can be a particular problem inside buildings, especially if the walls are thick and reinforced.

6. DATA - GPRS The set command specifies a profile for the context identified by the (local) context identification parameter, . Since this is the same parameter that is used in the +CGDCONT command, the +CGQREQ command is effectively an extension to the +CGDCONT command. The QoS profile consists of a number of parameters, each of which may be set to a separate value. A special form of the set command, +CGQREQ= causes the requested profile for context number to become undefined.
