5. system connector interface 24 lzt 123 7589 r1a connect all vcc pins together in your application in order to carry the current drawn by the radio device. the electrical characteristics for vcc are shown in the table below. the radio device has no internal capacitance to supply the large current peaks during gsm burst transmission. we recommend you follow these general guidelines: fit a low esr electrolytic cap acitor close to the radio device: > 1,000 f; < 100 m ? esr. make sure power supply to radio device line resistance is < 200 m ?. 5.5 battery charging input (chg_in) for battery powered applications, the radio device has a connection to aid and support battery charging. the typical design where this may be applicable is to power the radio de vice directly from a battery source connected to vcc (pins 1, 3, 5, 7, 9) and to provide a 5v dc power source (600ma max) to the chg_in connection (pin 11). the radio device can control an internal switching fet wh ich creates a charging pathway to the battery. while power is provided at chg_in, the battery charge can be maintained. if the power should fail or be removed at chg_in, the application will be supported by the battery alone. when chg_in voltage returns, the battery charging and maintenance will commence once more.
battery charging algorithms are unique to different battery types. sony ericsson mobile communications will not accept any responsibility or liability for damage, product failures, even death or injury occurring as a result of incompatible battery and charging algorithms being applied without their prior knowledge and consent. parameter mode limit vcc supply voltage nominal 3.6 v tolerance including ripple a a. measured at system connector pins. 3.4 v - 4.0 v over-voltage limit 5.5 v maximum ripple < 100 mv @ <200 khz; < 20 mv @ > 200 khz maximum allowable voltage drop burst transmission 200 mv current drawn, at full tx power < 500 ma (average) < 2 a (peak)
5. system connector interface 25 lzt 123 7589 r1a safety considerations should be taken into account. for example, monitoring the temperature of the battery. if the temperature of the battery exceeds its specification limits , battery charging must be stopped immediately. if the battery temperatur e continues to rise the application should be suspended or the battery disconnected. when charging lithium batteries, the battery pack must have an internal protection circuit in accordance with the manufacturer?s instructions. 5.6 turning the radio device on/off and the external power signal turning the radio device on figure 5.2 on timings and vio performance on/off pulled up internally through 39k ? t on t vio t cts t pulse software running ? t prst vcc on/off vio cts t o symbol parameters conditions min. typ max unit t reference time when vcc is within working limits (1) vcc > 3.2v on/off = vcc -- - - t time after t0 when the on/ off pulse can begin vcc > 3.2v 0 - - ms

8. hints for integrating the radio device 54 lzt 123 7589 r1a 8. hints for integrating the radio device this chapter gives you advice and helpful hints on how to integrate the radio device into your application from a hardware perspective. please read and consider the info rmation under the following headings before starting your integration work: safety advice and precautions. installation of the radio device. antenna. 8.1 safety advice and precautions 8.1.1 general always ensure that use of the radio device is permitted. the radio device may present a hazard if used in proximity to personal medical electronic devices. as a rule, the radio device must not be used in hospitals, airports or planes. you are responsible for observing your country?s safety standards, and where applicable the relevant wiring rules. never use the radio device at a gas station, refuelling point, blasting area or in any other environment where explosives may be present. operating the radio device close to other electronic devices, such as antennas, television sets, and radios may cause electromagnetic interference. never try to dismantle the radio device yourself. there are no components inside the radio device that can be serviced by the user. if you attempt to dismantle the radio device, you may invalidate the warranty. to protect the power supply cables and meet the fire safety requirements, it is recommended that the electrical circuits are supplied with a power regulator. the power regulator should be placed as close to the terminals of the power supply as possible. do not connect any incompatible co mponent or product to the radio device. sony ericsson does not warrant agai nst defects, non-conformities or deviations caused thereby. the connection/disconn ection method for the development board is by means of the dc power jack. for this reason, the mains supply should be situated close to the development board and be easily accessible.
8. hints for integrating the radio device 55 lzt 123 7589 r1a 8.1.2 sim card before handling the sim card in your application, ensure that you are not charged with static electricity. use proper precautions to avoid electrostatic discharges. the radio device must be switched off before the sim card is installed in your application. 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 radio device 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. 8.1.3 antenna 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 radio device to a single antenna. the radio device can be damaged by ra dio frequency energy from the transmitter of another radio device. like any mobile station, the antenna of the radio device emits radio frequency energy. to avoid emi (electromagnetic interference), you must determine whether the application itself, or equipment in the application?s proximity, needs furthe r 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 th e external signals cable. the radio device 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. in the final application, the antenna must be positioned more than 20 cm away from human bodies. when this rule cannot be applied, the application designer is responsible for providing the sar measurement test report and declaration. even if sar measurements are not required, it is considered good practice to insert a warning in any manual produced, indicating it is a radio product and that care should be taken.
8. hints for integrating the radio device 56 lzt 123 7589 r1a 8.2 installation of the radio device 8.2.1 where to install the radio device there are several conditions which need to be taken into consideration when designing your application as they might affect the radio device and its function. they are: environmental conditions the radio device 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. signal strength the radio device 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 radio device is to a radio base station. you must ensure that the location at which you intend to use the radio device, is within the network coverage area. degradation in signal strength can be the result of a disturbance from another source, for example an electro nic device in the immediate vicinity. more information about possible communication disturbances can be found in section 8.3.5, page 59. when an application is completed, you can verify signal strength by issuing the at command at+csq. see the at commands manual for further details. before installing the radio device, use an ordinary mobile telephone to check a possible location for it. in determining the location for the radio device and antenna, you should consider signal strength as well as cable length connection of components to radio device 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 radio device or equipment. network and subscription before your application is used, you must ensure that your chosen network provides the necessary te lecommunication se rvices. contact your service provider to obtain the necessary information.
8. hints for integrating the radio device 57 lzt 123 7589 r1a 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 2.3.2 short message service, page 10. 8.2.2 how to install the radio device 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 cu rrent. an electrolytic capacitor should be placed close to the power supply pins of the radio device to supply the peak currents during burst transmission. see 5.4 vcc - regulated power supply input, page 23. see section 5.2.1 general protection requirements, page 22. grounds a ground connection is provided at the mounting hole next to the rf connector on the radio device (see figure 5.1, page 19). connect this ground point to the dgnd pins of the radio device by the shortest, low- impedance path possible. the purpose of this connection is to allow any esd picked up by the antenna to bypass the radio device?s internal ground path. it is recommended that you use a cable with a maximum resistance of 5 m ? for the ground connection. agnd and dgnd are connected at a si ngle point inside the radio device. they must not be joined together in your application. audio use a coupling capacitor in atms line if the application does not use the radio device?s bias voltage. see also figure 5.5 microphone connections to the radio device, page 31. software upgrade to upgrade the software, the system connector must be accessible in your application. the pins service, td2, rd2 and the power signals are used for this purpose. please contact cu stomer support for more details.
8. hints for integrating the radio device 58 lzt 123 7589 r1a 8.3 antenna 8.3.1 general the antenna is the component in your system that maintains the radio link between the network and the radio de vice. 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 con cerning antenna type, antenna placement, antenna cable, and possible communicat ion 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. 8.3.2 antenna type make sure that you choose the right ty pe of antenna for the radio device. consider the following requirements: the antenna must be designed for the dual frequency bands in use: e-gsm900/gsm1800 for the GR47 and gsm 850/gsm1900 for the gr48; the impedance of the antenna and antenna cable must be 50 ? ; the antenna output-power handling must be a minimum of 2 w; the vswr value should be less than 3:1 to avoid damage to the radio device. 8.3.3 antenna placement the antenna should be placed away from electronic devices or other antennas. the recommended minimum distance between adjacent antennas, operating in a similar radi o frequency band, is at least 50 cm. 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 radio device. the radio device?s peak output power can reach 2 w. rf field strength varies with antenna type and distance. at 10 cm from the antenna the field strength may be up to 70 v/m and at 1m it will have reduced to 7 v/m.
8. hints for integrating the radio device 59 lzt 123 7589 r1a in general, ce-marked products for residential and commercial areas, and light industry can withstand a minimum of 3 v/m. 8.3.4 the antenna cable use 50 ? impedance low-loss cable and high-quality 50 ? impedance connectors (frequency range up to 2 ghz) 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 cabl es, connectors and adapters. each additional cable, connector or adapter causes a loss of signal power. 8.3.5 possible communication disturbances possible communication disturb ances 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 inte rfere with communication and may cause a delay, or at worst, a disruption.
9. embedded applications 60 lzt 123 7589 r1a 9. embedded applications the radio device has the capability to store and run customer written code in the form of a script during the processor?s idle time, through the use of an on board interpreter. 9.1 features main features of embedded a pplications ar e as follows. c based scripting language (sony ericsson specific); over the air upgrade of scripts (not gsm software); library of intrinsic functions; 2 scripts can be stored in the memory at any time but only 1 can be active. 9.2 implementation the radio device has up to 44k of space available for storage of two scripts in the scripting language and 25k of operating ram. structures included in this language are: if - then - else statements while loops for loops all hardware interfaces that are normally available to the radio device through the at commands are available to the embedded application. further drivers have been written such as m bus, keypad, spi and i 2 c for use by the embedded application (ea) through the use of the i/o pins. 9.2.1 limitations since the radio device 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 need s 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 m2 m 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.
9. embedded applications 61 lzt 123 7589 r1a 9.2.2 m2 m power ide (integrated development 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. the m2 m power application guide is available for implementing applications using the developer?s 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 sony ericsson mobile communications customer support.
10. tcp/ip stack 62 lzt 123 7589 r1a 10. tcp/ip stack an on board ip/tcp/udp stack has b een integrated into the software negating the need for the customer to implement one in their own code base. this is only accessible by using an embedded applications (see section 9) using intrinsic functions. 10.1 implementation the following types of commands allow various functions: open/closing ip connection - negoti ates/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 nslookup command in dos when 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 tran sparent communication link from the application to an internet server over gprs.
