GT47/GT48 Control Terminals2.1 DescriptionTwo Control Terminals make up the family; GT47 and GT48, for use in the E-GSM900/GSM1800 and GSM850/GSM1900 bands respectively. The Control Terminal has a radio device embedded in it. The GT47 incorporates the GR47 radio device; the GT48 incorporates the GR48 radio device.Note! This manual refers to the GT47 and GT48 as Control Terminals. If there is a difference in the functionality of the Control Terminals the GT47 and GT48 information will be listed separately.The Control Terminal 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 Control Terminal 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 Control Terminal also has an audio interface allowing an analogue handset to be connected. When the Control Terminal is integrated into an external application, a wireless communications system is created.A typical end-to-end system consists of a micro controller in an external application communicating, via the Control Terminal, with a remote terminal or host using the GSM network. The micro controller uses a set of AT commands to control the Control Terminal, and to set up the end-to-end communications link, via its 9-way RS232 serial interface.These Control Terminals 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 Management2.2 Highlights• Intelligent, versatile GSM/GPRS Control Terminal• Dual band, EGSM 900/GSM1800 (GT47); GSM 850/GSM1900 (GT48)• Customised applications can be embedded and run independently• Self contained terminal with standard connectors

Additionally there are several extended input/output signals available that can be used to control or interface external systems and devices.General signal description: 1 VIN2 OUT-2 3 IN-1 4 TO_IN 5 OUT-1 6 GND
5. ELECTRICAL DESCRIPTION23LZ T 123 7605 P1CThe power connector electrical characteristics are listed below:Note! Signal OUT-2 on the RJ12 connector is switched in parallel to signal OUT-4 on the 15-pin high density socket. The individual output signals are generated by two different low side switches inside the module driven from a common control signal.5.1.1 Power Supply InterfaceThe supply voltage VIN and GND are protected against polarity reversal and over voltage.The Control Terminal switches on automatically once the VIN voltage is applied. Note! The Control Terminal will not switch on if TO_IN is shorted to ground when the dc supply is applied.Note! For more information on switching the Control Terminal on and off please see section “Operation”, page 39Note! Please be aware that the total current carried via either the VIN or GND pins will be the sum of the intrinsic power consumption of the Control Terminal and any drive current supplied via OUT-1 or OUT-2 (or other IOs). The current on either of the VIN or GND pins must not exceed 1.5A.Caution! It is recommended that the system integrator provides appropriate fusing otherwise the Control Terminal may be damaged. See “Current Consumption with external +4.8V Supply Active”, page 53 for more details.Pin Signal Dir Limits Description1 VIN I5 to 32V Positive power input2 OUT-2 O 32V, 0.25A Low side switch, short circuit protected3IN-1 I–0.5 to 32V Digital InputVIH > 3V, VIL < 2.8VInternal Pull Down of 40kΩ4 TO_IN I –0.5 to 32V Active low control line used to switch the GT47 off/on.VIH > 5V, VIL < 2VPower off/on: t > 0.2sInternal Pull Up to VIN of 20kΩ5OUT-1 O VIN, 0.4A High side switch, short circuit protected6 GND I - Negative power (ground) input and return path for TO_IN and the extended inputs and outputs

Its state is detected by IO5 of the embedded Radio Device engine, see Control Terminal-Radio Device signal cross reference table, page 30.The distinction between low level and high level signals is at the voltage level of 3 V. Voltages above 3 V are detected as high level voltages and voltages below 2.8 V are detected as low level.Digital OutputsThe RJ12 power supply connector has two different output drivers:• OUT-1 is driven by a high side switch that applies VIN to pin 5 of the RJ12 connector. IO1 of the embedded radio device is used to activate the OUT-1 signal, see Control Terminal - radio device signal cross reference table, page 30.• OUT-2 is driven by a low side switch that shorts pin 2 of the RJ12 connector to ground when activated. IO3 of the embedded Radio Device engine is used to activate OUT-2, see Control Terminal - Radio Device signal cross reference table, page 30.VIN MonitoringThe voltage, VIN, can be monitored internally by the Control Terminal, for example if the Control Terminal is supplied from an external battery. ADC1 on the Radio Device is used for this purpose, see Control Terminal-Radio Device signal cross reference table, and is calibrated to operate in the voltage range 0 – 31.875 V. The resolution of the 8 bit converter, ADC1, provides a measurement accuracy of approximately 3%. IMAGE -TBD

5. ELECTRICAL DESCRIPTION27LZ T 123 7605 P1CSerial Data To Control Terminal (TD) Pin 3TD is an input signal, used by the external application to send data to the Control Terminal.5.2.4 Control Signals - RTS, CTS, DTR, DSR, DCD, RIRequest to Send (RTS) Pin 7Used to condition the Control Terminal for data transmission. The default level is inactive by internal pull down.The exact behaviour of RTS is defined by an AT command. Software or hardware flow control can be selected. Hardware flow control is the default selection.The application must pull RTS high to enable transmission from the Control Terminal. Clear To Send (CTS) Pin 8CTS indicates that the Control Terminal 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.Data Terminal Ready (DTR) Pin 13DTR indicates that the DTE is ready to send and receive data. It also acts as a hardware ‘hang-up’, terminating calls when switched low. The signal is active high. You can define the exact behaviour of DTR with an AT command.Data Set Ready (DSR) Pin 6An active DSR signal is sent from the Control Terminal to the application (DTE) to confirm that a communications path has been established. DSR has two modes of operation, use the AT command AT&S to set the mode.Data Carrier Detect (DCD) Pin 1DCD indicates that the Control Terminal is receiving a valid carrier (data signal) when high. You can define the exact behaviour of DCD with an AT command.Ring Indicator (RI) Pin 10RI indicates that a ringing signal is being received by the Control Terminal when high. You can define the exact behaviour of RI with an AT command.
5. ELECTRICAL DESCRIPTION28LZ T 123 7605 P1CAlternative ConfigurationIt is possible to reconfigure one or more of the signals in this section (RTS, CTS, DTR, DSR DCD and RI) to be used as digital inputs or outputs if the full RS232 serial interface is not required. Configuration is achieved using AT command (AT+E2IO) or via embedded application intrinsic functions, please refer to Control Terminal-Radio Device signal cross reference table, page 30. To be reconfigured as a digital IO, each signal must retain the direction and the logic voltage levels attributed to it when used as an RS232 signal. For example DSR can only be reconfigured as a digital output with Vout ≥ ±5V.5.2.5 Extended I/O SignalsPlease refer to Control Terminal-Radio Device signal cross reference table, page 30, for more information on the relationship between signal names and pin numbers of the Control Terminal and the embedded Radio Device engine.Digital Inputs Pin 4 & 11Digital inputs IN-2 and IN-3 are available on the HD15 connector via pins 11 and 4 respectively. The inputs are detected via signals IO4 and IO7 of the embedded Radio Device engine.Note! As an alternative configuration signals IN-2 and IN-3 can be used to support a second RS232 serial interface as RTS-2 and TD-2. Further information is given below.Analog Input Pin 15The signal ANA_IN can be used for measuring analog input values in the range 0 to 12.75V. ADC2 of the embedded GR47 is used to detect ANA_IN.The resolution of the converter is 8 bit with an measurement accuracy of about 3%.The input impedance of the ANA_IN pin is 50 kΩ.Digital Outputs Pin 5 & 12Digital outputs OUT-3 and OUT-4 are available on the HD15 connector via pins 5 and 12 respectively. The outputs are controlled via signals IO8 and IO3 of the embedded Radio Device engine.Signal OUT-4 on the HD15 connector is switched in parallel to signal OUT-2 on the RJ12 connector. The individual output signals are generated by two different low side switches inside the terminal driven from the common control signal, IO3. All Control Terminal output signals

This allows the external application hardware to determine the desired logic voltage levels with the appropriate pull-up.The output drivers are low side switches which short the pin to GND if they are activated.Note! As an alternative configuration signals OUT-3 and OUT-4 can be used to support a second RS232 serial interface as RD-2 and CTS-2. Further information is given below.+4.8V Output Supply Pin 9There is a voltage regulator implemented inside the module that is capable of supplying an external voltage source of +4.8V with a maximum current of 75 mA.The voltage source can be switched on/off with the DAC signal of the internal Radio Device GSM engine.By default the voltage source is switched on. A high level of 2.75V at the DAC output of the Radio Device GSM engine will switch the voltage source off.Note! The +4.8V source may be switched on/off via an embedded or external application and so may be used as an optional digital output with levels of +4.8V and open circuit.5.2.6 Second RS232 Serial InterfaceIN-3 and OUT-3 can be automatically reconfigured as signals TD-2 and RD-2, of a second serial interface, by enabling UART3 of the internal Radio Device. UART 3 may be enabled using AT command or intrinsic function.In addition, IN-2 and OUT-4 can be automatically reconfigured as signals RTS-2 and CTS-2 of the second serial interface by enabling hardware flow control for UART3 on the internal Radio Device. Hardware flow control can be enabled using intrinsic function only.Note! The signal level thresholds for each of the digital inputs of the second serial interface are: 3V<VIH<32V and VIL< 2.8V.An external RS232 transceiver component may be used to convert the serial interface to standard RS232 electrical levels. The Control Terminal's +4.8 V output can be used to provide power for the transceiver.

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 incorporates a SIM presence switch which detects whether a SIM card is inserted. The full operation of the Control Terminal relies on a SIM card being inserted.Caution! Some Control Terminal functionality may be lost if you try to operate it without a SIM card.The SIM presence switch also ensures that when a SIM card is inserted or removed the unit is reset, as long as the Control Terminal is switched ON.Loggin with the SIM InTBALogging with the SIM OutTBD
5. ELECTRICAL DESCRIPTION35LZ T 123 7605 P1C5.6 Real Time ClockThe module 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 Control Terminal is turned on. When the Control Terminal is powered off, a storage energy device within the module provides back-up power to maintain the RTC for several hours - please contact Sony Ericsson Customer Support for more information.The RTC back-up is fully charged after approximately 10 hours with the control terminal turned on. Once fully charged the RTC back-up will maintain the Real Time Clock for at least 8 hours.5.7 Software UpdatesIt is possible, and sometimes necessary, to update the module software. Updates must be carried out by a Sony Ericsson approved technician. Please contact your supplier for details (see “Service and Support”, page 9).
6. EMBEDDED APPLICATIONS36LZ T 123 7605 P1C6. Embedded ApplicationsThe module has the capability to store, and run customer written code in the form of a script during the processors idle time, through the use of an on board interpreter.6.1 FeaturesMain features of embedded applications are as follows.• C based scripting language (Sony Ericsson specific)• Over the air upgrade of scripts (NOT GSM software)• Library of intrinsic functions• Two radio device scripts can be stored, but only one can run at any one time.6.2 ImplementationThe module has up to 44kbytes of space available for storage of two scripts in the scripting language and 25kbytes of operating RAM. Structures included in this language are:• If - then - else statements• While loops•For loopsAll hardware interfaces that are normally available to the module through the AT commands are available to the embedded application. Further drivers have been written such as M bus and I2C for use by the embedded application (EA) through the use of the I/O pins.6.2.1 LimitationsSince the module is processing the script using its own memory, limitations are placed onto the scripts that are run.• A direct comparison cannot be made to a fully compiled C program in terms of size but a gauge of script size is that if each line were 128 characters long in the script then the script could be 350 lines long. • Processing power is something that needs to be considered as the script is run as a low priority process within the software. However, controller mode stops GSM operation and provides all the processing power for the script to be run. See the M2m Power Application Guide for more details.• Code cannot be ported directly from an existing application and loaded directly onto the radio device. It must be re written in the Sony Ericsson Mobile script language so that the radio device interpreter can function correctly.
6. EMBEDDED APPLICATIONS37LZ T 123 7605 P1C6.2.2 M2mpower IDE (Integrated Developers Environment)The IDE is a windows based package which allows the user to write, simulate, debug and download the application into a radio device with the embedded application (EA) software. The standard version is designed to run on Windows XP and 2000, other versions are available for 98 if required.A M2m Power application guide is available for implementing applications using the developers kit and the embedded application (EA) functionality.This is a required package to be able to implement an embedded application (EA).For further information please contact SEM customer support.
7. TCP/IP STACK38LZ T 123 7605 P1C7. TCP/IP StackAn on board IP/TCP/UDP stack has been integrated into the software negating the need for the customer to implement one in their own code base.This is available through the embedded applications (see previous section) using intrinsic functions and also through AT commands (see GR47/GR48 AT commands manual).7.1 ImplementationThe following types of commands allow various functions:• Open/closing IP connection - Negotiates/closes a dynamic IP address with the web server.• Send/Receive TCP packets - Performs all TCP operations to send and receive packets.• Send/Receive UDP packets - Performs all UDP operations to send and receive packets.• Resolve URL to an IP address - Similar to lookup command in DOSWhen the unit is set up and controlled using the embedded applications either the embedded applications or an external application can generate data to be sent and pass it to the radio device for transmission.This effectively provides a transparent communication link to an internet server from the application over GPRS.
8. OPERATION39LZ T 123 7605 P1C8. Operation8.1 Switching On the Control TerminalThe Control Terminal is turned ON automatically once DC power is applied. If the Control Terminal is turned OFF, using one of the methods described in 8.2, the Control Terminal can be turned ON again through one of two methods:• pull signal TO_IN to ground for t >0.2s, then release. • activate the main RS232 control line DTR, low to high for >0.2s The Control Terminal is fully operational after 4 seconds. Logging onto a network may take longer than this and is outside the control of the Control Terminal.Note! The Control Terminal will not switch on if TO_IN is shorted to ground when the dc supply is applied.8.2 Switching Off the Control TerminalThere are two ways to switch off the Control Terminal as described below.• Use the appropriate AT command (AT+CFUN);• pull signal TO_IN to ground for t >0.2s, then release.8.3 Resetting the Control TerminalA full system reset, independent of the status of the software, may be applied to the Control Terminal as follows:• assert HR_IN high for > 3.5s.8.4 Operating States/LEDThe Control Terminal has a green LED, as depicted below, which is used to indicate various operating states. These states are described in following table.LE D
8. OPERATION40LZ T 123 7605 P1C8.5 Power Save The Control Terminal can power down the main RS232 IC when not needed in order to minimise power consumption. The IC is powered up automatically at start-up but can be powered down by setting the output of IO2 on the embedded Radio Device (pin22) to low via AT command or embedded application. Once powered down, the IC can be woken up by setting the output of IO2 high on the Radio Device via AT Command. Even when powered down the IC is able to pass a DTR signal received on the serial interface. Therefore an embedded application that monitors DTR, while the IC is powered down, can be made to wake up the IC, if a signal is received, by setting IO2 on the Radio Device high.8.6 Controller ModeThe Control Terminal, when powered up, will normally start up its GSM signalling software and look to register on the GSM network. Any embedded application script runs as a background process as and when the GSM software is idle. A feature available via embedded applications allows the Control Terminal to be placed in ‘controller mode’ whereby the Control Terminal powers up with a minimal subset of radio functionality. The GSM signalling software is halted and the embedded applications script has full control of the processor.Controller mode allows an application to run with more predictable response times.Operating state LEDAfter switching on the Control Terminal On after 4sControl Terminal switched off or power removed from the moduleOffStandby or talk FlashingNo network, network search, no SIM card, no PIN entered On
9. SAFETY AND PRODUCT CARE41LZ T 123 7605 P1C9. Safety and Product CarePlease read the information in this section and the information in “Installation of the Control Terminal”, page 44, before starting your integration work.9.1 Safety InstructionsPLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM.• Always ensure that use of the Control Terminal is permitted. The Control Terminal may present a hazard if used in proximity to personal medical electronic devices. As a rule, the Control Terminal must not be used in hospitals, airports or planes.• Never use the Control Terminal at a gas station, refuelling point, blasting area or in any other environment where explosives may be present.• Operating the Control Terminal close to other electronic devices, such as antennas, television sets, and radios may cause electromagnetic interference.• This product is intended to be used with the antenna or other radiating element at least 20cm away from any part of the human body. In applications where this rule cannot be applied, the application designer is responsible for providing the SAR measurement test report and declaration.• You are responsible for observing your country's safety standards, and where applicable, the relevant wiring rules.9.2 General Precautions• The Control Terminal as a stand alone item is designed for indoor use only. To use outside it must be integrated into a weatherproof enclosure. Do not exceed the environmental and electrical limits as specified in “Technical Data”, page 49.• Avoid exposing the Control Terminal to lighted cigarettes, naked flames or to extreme hot or cold temperature.• Never try to dismantle the Control Terminal yourself. There are no components inside the Control Terminal that can be serviced by the user. If you attempt to dismantle the Control Terminal, you may invalidate the warranty.• The Control Terminal must not be installed or located where the surface temperature of the plastic case may exceed 85°C.• All cables connected to the Control Terminal must be secured or clamped, immediately adjacent to the Control Terminal's connectors, to
9. SAFETY AND PRODUCT CARE42LZ T 123 7605 P1Cprovide strain relief and to avoid transmitting excessive vibration to the Control Terminal in the installation.• Ensure the d.c. cable, supplying power to the Control Terminal, does not exceed 3 metres. For longer distances please contact Sony Ericsson Service and Support.• To protect power supply cables and meet the fire safety requirements when the unit is powered from a battery or a high current supply, connect a fast 1.5A fuse in line with the positive supply. An appropiate fuse should be used see section “Power Supply”, page 45• Do not connect any incompatible component or product to the Control Terminal.Note! Sony Ericsson may refuse warranty claims where evidence of product misuse is found.9.3 SIM Card Precautions• Before handling the SIM card in your application, ensure that you are not charged with static electricity. Use proper precautions to avoid electrostatic discharges.• 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 Control Terminal 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. This will ensure that the SIM card cannot be used by an unauthorized person.9.4 Antenna Precautions• If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided by the antenna manufacturer.• Never connect more than one Control Terminal to a single antenna. The Control Terminal can be damaged by radio frequency energy from the transmitter of another Control Terminal.• Like any mobile station, the antenna of the Control Terminal emits radio frequency energy. To avoid EMI (electromagnetic interference), you must determine whether the application itself, or equipment in the application’s proximity, needs further protection against radio emission and the disturbances it might cause. Protection is secured either by shielding the surrounding electronics or by moving the antenna away from the electronics and the external signals cable.
9. SAFETY AND PRODUCT CARE43LZ T 123 7605 P1C• The Control Terminal and antenna may be damaged if either come into contact with ground potentials other than the one in your application. Beware, ground potential are not always what they appear to be.
10. INSTALLATION OF THE CONTROL TERMINAL44LZ T 123 7605 P1C10. Installation of the Control TerminalThis chapter gives you advice and helpful hints on how to integrate the Control Terminal into your application from a hardware perspective.Please read the information given in “Safety and Product Care”, page 41 and then the read the information in this section before starting your integration work.10.1 Where to Install the Control TerminalThere are several conditions which need to be taken into consideration when designing your application as they might affect the Control Terminal and its function. They are:10.1.1 Environmental ConditionsThe Control Terminal must be installed so that the environmental conditions stated in the Technical Data chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical specifications in the Technical Data section must not be exceeded.10.1.2 Signal StrengthThe Control Terminal 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 Control Terminal is to a radio base station. You must ensure that the location at which you intend to use the Control Terminal, is within the network coverage area. Degradation in signal strength can be the result of a disturbance from another source, for example an electronic device in the immediate vicinity. More information about possible communication disturbances can be found in section 10.3.5, page 47.When an application is completed, you can verify signal strength by issuing the AT command AT+CSQ. See the GR47/GR48 AT Commands Manual for more details.Tip! Before installing the Control Terminal, use an ordinary mobile telephone to check a possible location for it. In determining the location for the Control Terminal and antenna, you should consider signal strength as well as cable length
10. INSTALLATION OF THE CONTROL TERMINAL45LZ T 123 7605 P1C10.1.3 Connection of ComponentsThe integrator is responsible for the final integrated system. Incorrectly designed or installed, external components may cause radiation limits to be exceeded. For instance, improperly made connections or improperly installed antennas can disturb the network and lead to malfunctions in the Control Terminal or equipment.10.1.4 Network and Subscription• Before your application is used, you must ensure that your chosen network provides the necessary telecommunication services. Contact your service provider to obtain the necessary information.• If you intend to use SMS in the application, ensure this is included in your (voice) subscription.• Consider the choice of the supplementary services described in section “Short Message Service”, page 11.10.2 How to Install the Control Terminal10.2.1 Power Supply• Use a high-quality power supply cable with low resistance. This ensures that the voltages at the connector pins are within the allowed range, even during the maximum peak current.• When the unit is powered from a battery or a high current supply, connect a fast 1.5A fuse in line with the positive supply. This protects the power cabling and Control Terminal.10.2.2 Securing the Control Terminal• Before securing the Control Terminal 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 Control Terminal prior to securing it in the application.• Securely attach the Control Terminal to the host application using two 3mm diameter pan-head screws of appropriate length as shown below.Caution! Do not exceed a torque of 25Ncm when tightening the fixings screws. Excessive torque applied to the screws can crack the plastic case.
10. INSTALLATION OF THE CONTROL TERMINAL46LZ T 123 7605 P1C10.3 Antenna10.3.1 GeneralThe antenna is the component in your system that maintains the radio link between the network and the Control Terminal. Since the antenna transmits and receives electromagnetic energy, its efficient function will depend on:• the type of antenna (for example, circular or directional);• the placement of the antenna;• communication disturbances in the vicinity in which the antenna operates.In the sections below, issues concerning antenna type, antenna placement, antenna cable, and possible communication disturbances are addressed.In any event, you should contact your local antenna manufacturer for additional information concerning antenna type, cables, connectors, antenna placement, and the surrounding area. You should also 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.10.3.2 Antenna TypeMake sure that you choose the right type of antenna for the Control Terminal. Consider the following requirements:• the antenna must be designed for the dual frequency bands in use: EGSM 900/GSM 1800 for GT47, GSM 850/ GSM 1900 for GT48• the impedance of the antenna and antenna cable must be 50Ω • the antenna output-power handling must be a minimum of 2W;• the VSWR value should be less than 3:1 to avoid damage to the Control Terminal.10.3.3 Antenna PlacementThe antenna should be placed away from electronic devices or other antennas. The recommended minimum distance between adjacent antennas, operating in a similar radio frequency band, is at least 50cm.If signal strength is weak, it is useful to face a directional antenna at the closest radio base station. This can increase the strength of the signal received by the Control Terminal.The Control Terminal’s peak output power can reach 2W. RF field strength varies with antenna type and distance. At 10cm from the antenna the field strength may be up to 70V/m and at 1m it will have reduced to 7V/m.
10. INSTALLATION OF THE CONTROL TERMINAL47LZ T 123 7605 P1CIn general, CE-marked products for residential and commercial areas, and light industry can withstand a minimum of 3V/m.10.3.4 The Antenna CableUse 50Ω impedance low-loss cable and high-quality 50Ω impedance connectors (frequency range up to 2GHz) to avoid RF losses. Ensure that the antenna cable is as short as possible.The Voltage Standing-Wave Ratio (VSWR) may depend on the effectiveness of the antenna, cable and connectors. In addition, if you use an adapter between the antenna cable and the antenna connector, it is crucial that the antenna cable is a high-quality, low-loss cable.Minimize the use of extension cables, connectors and adapters. Each additional cable, connector or adapter causes a loss of signal power.10.3.5 Possible Communication DisturbancesPossible communication disturbances include the following:•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.•Multi-path fading is a sudden decrease or increase in the signal strength. This is the result of interference caused when direct and reflected signals reach the antenna simultaneously. Surfaces such as buildings, streets, vehicles, etc., can reflect signals.•Hand-over occurs as you move from one cell to another in the GSM network. Your mobile application call is transferred from one cell to the next. Hand-over can briefly interfere with communication and may cause a delay, or at worst, a disruption.10.4 AccessoriesThe Control Terminal has been type approved together with a range of accessories including:Power Supply (GT47 only)1.
