2. GT47/GT48 CONTROL TERMINALS The Control Terminal supports HR, FR and EFR vocoders. The GT48 also supports the Adaptive Multi Rate (AMR) type of vocoder. 2.4.4 Data The Control Terminal supports the following data protocols: • GPRS (General Packet Radio Service). The Control Terminal is Class B, which provide simultaneous activation and attachment of GPRS and GSM services.
2. GT47/GT48 CONTROL TERMINALS 2.4.7 Serial Communication The Control Terminal enables an end-to-end communication path to be established between the telemetry/telematics application, either hosted internal or connected externally, and a remote terminal or host, via the GSM network. Once a path has been set up, voice or data communication can take place. An RS232 9-signal serial interface is available via the Control Terminal’s 15-way high density data connector.
2. GT47/GT48 CONTROL TERMINALS The drivers controlling certain outputs have been designed to carry higher currents than normal logic IOs. They can be used to activate or power external devices, for example a switch or a relay. A+4.8V output is available, if required, to power external devices. 2.4.

5. ELECTRICAL DESCRIPTION Serial Data To Control Terminal (TD) Pin 3 TD 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, RI Request to Send (RTS) Pin 7 Used 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.
5. ELECTRICAL DESCRIPTION Alternative Configuration It 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.
5. ELECTRICAL DESCRIPTION driven by low side switches return to open circuit when deactivated. 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.

5. ELECTRICAL DESCRIPTION 5.4 Antenna Connector The antenna connector allows transmission of radio frequency (RF) signals between the Control Terminal and an external customer-supplied antenna. The module is fitted with a 50Ω, FME male coaxial jack as shown below. RF Signal GND The table below shows the antenna electrical characteristics: Parameter Limit Nominal impedance 50Ω (SWR better than 2.
5. ELECTRICAL DESCRIPTION 5.5 SIM Card Reader The module 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 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.
5. ELECTRICAL DESCRIPTION 5.6 Real Time Clock The 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.
6. EMBEDDED APPLICATIONS 6. Embedded Applications The 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 Features Main 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. EMBEDDED APPLICATIONS 6.2.2 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.
7. TCP/IP STACK 7. TCP/IP Stack An 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 Implementation The following types of commands allow various functions: • Open/closing IP connection - Negotiates/closes a dynamic IP address with the web server.
8. OPERATION 8. Operation 8.1 Switching On the Control Terminal The 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.
8. OPERATION Operating state LED After switching on the Control Terminal On after 4s Control Terminal switched off or power removed from the module Off Standby or talk Flashing No network, network search, no SIM card, no PIN entered On 8.5 Power Save The Control Terminal can power down the main RS232 IC when not needed in order to minimise power consumption.
9. SAFETY AND PRODUCT CARE 9. Safety and Product Care Please 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 Instructions PLEASE 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.
9. SAFETY AND PRODUCT CARE provide 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.
9. SAFETY AND PRODUCT CARE • 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 TERMINAL 10. Installation of the Control Terminal This 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.
10. INSTALLATION OF THE CONTROL TERMINAL 10.1.3 Connection of Components The 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.
10. INSTALLATION OF THE CONTROL TERMINAL 10.3 Antenna 10.3.1 General The 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.
10. INSTALLATION OF THE CONTROL TERMINAL In general, CE-marked products for residential and commercial areas, and light industry can withstand a minimum of 3V/m. 10.3.4 The Antenna Cable Use 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.
