Modes of Operation 4.1 Turn On/Off the unit. The D15 is powered from a single power supply in the range of 3.0 to 6.0 Vdc. The unit will not power up automatically by connecting the power and there are two ways to turn the unit On. 4.1.1 Turn On/Off the unit using the ON/OFF pin. The On/Off pin (pin no’ 14 at the ZIF connector & pin no’ 18 at the DIN connector) is used as a toggel input to turn On and Off the unit. Any drop to ground in this pin will change the status. To verify that the unit is On or Off you have to check the DSC_EN line, If it is high the unit is On If it is low the unit is Off. 14 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 The timming for this process are the follow: Turn On the unit using the ON/OFF pin Turn On and Off the unit using the ON/OFF pin 15 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 4.1.2 Turn On the unit using the TS pin. The main used of the TS line is for units connected to a mobile device in witch the current consuption is not the main consern. The TS line is used to turn On the unit. This line can’t turn Off the unit. When this line is rised up it will turn On the unit. This line is used for example to turn On the unit when power is connected to the unit. (Like Ignition line in a car kit). Be aware that if you keep this line high all the time the unit will not go to Sleep mode (current save mode), So it is recommended to turn On the unit and than drop this line. 16 Exhibit 8 APPLICANT: MOTOROLA, INC.

This mode is for computer aplication in witch an application SW “SoftGSM” is use. This alowed the D15 to work with V42.bis (data compression), transfer fax and SMS. RS232 full flow control. This is the defaul setting for the D15. In this mode we can transfer data and SMS using a full flow control (HW flow control), Xon/Xoff or non flow control. There is now FAX capability in this mode. 19 Exhibit 8 APPLICANT: MOTOROLA, INC. 4.2.1 FCC ID: IHDT6AC1 Using the SoftGSM. 4.2.1.1 SoftGSM Selection The selection of SoftGSM is done by Hardware in the user application. In order to switch to this mode the user need to connect pulldown resistors of 22Kohm in the Downlink line (pin no’23 in the zif connector or pin no’22 in the 28 pin) and the DCS_EN line (pin no’22 in the zif connector or pin no’20 in the 28 pin). In this mode the necessary lines are: TXD, RXD. An example for the circuitry to add the pulldown resistor can be seen in Pharagraph ??? EV_board design. 4.2.1.2 File / Fax / SMS transfer in SoftGSM mode. To Transfer a file in softGsm you need to: 1. connect the RX/TX lines of the D15 a a comm port of the computer. .(the levels should be converted to RS232 or use a EV board or equivqlent). 2. Run the SoftGsm Application in the computer. 3. The SoftGsm program will open a phone tools application. 4. Use the phone application to send/Receive file/Fax/SMS . 20 Exhibit 8 APPLICANT: MOTOROLA, INC.

TBD 23 Exhibit 8 APPLICANT: MOTOROLA, INC. 4.2.2 FCC ID: IHDT6AC1 Using RS232. 4.2.2.1 RS232 Selection The RS232 is the default setting in the D15 and no HW selection is needed. The RS232 can use 3 different modes of setting to the DTE device: HW (Hardware) flow control – all RS232 lines are used (DTR, DSR, RTS, CTS, TXD, RXD, DCD, RI, GND). None flow control – DTR, DSR, TXD, RXD, DCD, RI, GND are required. Xon / Xoff flow control – DTR, DSR, TXD, RXD, DCD, RI, GND are required. 4.2.2.2 work with RS232 with "sleep mode" If the D15 will have no accessories and the unit is camped the D15 will go to a "sleep mode" (current save mode). During this period of time the RS232 is not responding to any command from the DTE device(Uart is not activated).In order to make the unit to wake up when the DTE will like to communicate with the radio the user have two options: 1. Activate the RTS During all the DTE/DCE dialog. (Internaly the TS line will be activated). After the communication disable the RTS in order to go back to sleep mode. 2. Activate the TS During all the DTE/DCE dialog. After the communication disable the TS in order to go back to sleep mode. 24 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 4.2.2.3 File transfer in RS232 mode. To Transfer a file in RS232 you need to: 1. connect the relevant lines depend on the mode to a comm port of the computer.(the levels should be converted to RS232 or use a EV board or equivqlent). 2. Run Hyper terminal application or equivalent in the computer. (in the final application it will be the user program). 3. Select the flow control / Comm and baud rate. 4.

TBD 35 Exhibit 8 APPLICANT: MOTOROLA, INC. 4.3 FCC ID: IHDT6AC1 Voice connectivity. The D15 is an OEM Data & Voice module. The voice connectivity can be done in two main channels – analoge voice, Digital voice. 4.3.1 Digital voice: The Digital voice is done using the Motorola DCS bus. This bus is an Motorola Propriretry bus and details can be received after an agreement. General connections: DCS_EN User DSC Drivers + Audio Drivers DownLink D15 Uplink In case that the D15 is connected to a standard Motorola Car Kit the TS line should be connected to VCC in order to turn On the unit using the Ignition line. 36 Exhibit 8 APPLICANT: MOTOROLA, INC. 4.3.2 FCC ID: IHDT6AC1 Analog Audio. The D15 is driving out the analog audio detected by the radio. The D15 is not including any audio drivers. The user have to include the audio drivers in is application. An example for audio drivers can be seen in the EV board appendix ??. The D15 can provide the analog audio in two ways: - Analog audio to by drived to an Headset – Default. - Analog audio with Echo canceller activated – for Hands free applications. When an Headset is used in the user application than audio drivers for the headset are needed. When an external Speaker and Microphone are used drivers for them are required and activation of Echo canceller in the D15 DSP is required. To activate the Echo canceller you need to type an AT command in the Data port. ATs96=1 will activate the Echo canceller. ATS96=0 will disable the Echo canceller. The block diagram for the required drivers are shown below, But detailled example of drivers design you can see the Evaluation board design, Pharagraph ???. 37 Exhibit 8 APPLICANT: MOTOROLA, INC.

FCC ID: IHDT6AC1 Design Consideration 5.1 Power supply considerations. Current requirements in each mode. 5.2 Audio considerations.to refer to EV board chepter in appendix.Car Kit connectionsl. 5.3 Data port considerations & Levels. 5.4 SIM card considarations. 5.5 ESD considerations. 5.6 Antenna 5.7 Software 5.8 Mechanical 5.1 Power supply consideration. 5.1.1 Power Supply losses. The D15 is specified to operate from 3.0V to 6.0V. In order to be able to work in the lowest battery values it is important to verify the losses in the power supplies lines, Flat cable and in the user PCB. The D15 is a GSM phone that transmits in pulses of about 0.5mS any 4mS. The Peak current is about 1.5A. The VCC line will drop down in the TX periods: Transmit Periods TX TX TX VCC In order to minimize the ∆ it is recommended to use a short Flat cable as possible and to put a 1000uF capacitor (or maximum possible) in the D15 VCC input. 5.1.2 Current consumption in D15: In order to design the power supply correctly you need to take in account the current consumption of the D15 in the different 40 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 modes. Mode Current consumption D15 with no accessory when no call is in process <11mA Typical 10mA. D15 with no accessory but TS or RTS are ON < 50mA. D15 during searching time <180mA typical average 80mA. D15 with DSC bus accessory(like Handset) when no call is in process Typical 40 mA. D15 during a call in maximum power level <1.5A Peak, Average 300mA. D15 during a call in GSM power level #10 (for Example) <0.7A Peak, Average 175mA 41 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 5.1.3 How / When to make the unit to wakeup. If the D15 will have no accessories and the unit is camped the D15 will go to a "sleep mode" (current save mode). During this period of time the RS232 is not responding to any command from the DTE device.In order to make the unit to wake up when the DTE will like to communicate with the radio the user have two options: 1. Activate the RTS During all the DTE/DCE dialog. (Internaly the TS line will be activated). After the communication disable the RTS in order to go back to sleep mode. 2. Activate the TS During all the DTE/DCE dialog. After the communication disable the TS in order to go back to sleep mode. Note: If the RTS or TS line will be active all the time the unit will not switch to Sleep mode and the avarage current consumption without a call will be arround 50mA. Timing diagrams should be added. - TBD 5.2 Audio circuits consideration. The D15 is able to make a voice call as well as Data calls. In voice calls the audio can be routed in a few channels: Digital audio chanel - Audio is sent via the DSC bus. Analog audio channel - Drived externaly to audio devices. Analog audio channel in Hands free mode - D15 sens the audio out with the Echo canceling ON in the DSP, External drivers are required. The Selection between each one of the channels can be done according to the table XX in paragraph 4.3.2. 42 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 5.2.1 Digital audio. In case of digital audio channel a DCS drives is in used. The consideration that should be taken in this case is to be aware of the present of the hook switch. The hook switch will destinguish if the handset is In/Out of use. There are two DSC bus accessories for audio defined for the D15: External Handset. DHFA - Car Kit for Hands Free. 5.2.2 Analog Audio without Handsfree. The D15 will drive the audio out/in in order to allowed a voice call. In order to connect an Headset it is needed to amplified the speaker and microphone channels. An example for these drivers can be seen in Apendix ?? EV board. Other point to be taken in consideration is the Buzz noise existing in GSM phones due to the transmission rate (217Hz).In order to minimize this noise the D15 have a separate ground for the analog circuits. Customer side D15 Analog Circuits Analog Ground Digital Ground Digital Ground PS 43 Logic Circuits Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 The main problem causing the Buzz is drops in the Ground line because the peak current during TX mode. In order to minimize the Buzz the following acts should be done: - Use short Flat cable. - Connect the analog ground from the D15 to all the analog circuits in the customer application without connecting them to the power supply ground. - all the capacitors to ground in the audio circuits should be connected to the analog ground. - Any reference voltage that may be used should have the external capacitor connected to the analog ground. 5.2.3 Analog Audio with Handsfree The audio In/Out from the D15 for analog Handsfree are the same as for non Handsfree.All the consideration from Paragraph 5.2.2 are applicable for this mode too. The additional consideration in this case is to switch the D15 DSP to Echo cancelling mode. In oreder to switch to handsfree mode use the RS232 port by sending a switch command. ATS96=1 ATS96=0 Echo canceller is activate. (Handsfree) Echo canceller is disabled. (headset - Default) 44 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 5.3 Data port considerations. 5.3.1 Data levels. The D15 data lines are operating in 0 to 5V logic. All the In/Out signals are bufferd by an MC74VHCT244 buffer. DTR, DSR, RTS, CTS, DCD lines are "1" (active) in 0V and "0" (inactive) in 5V. The signal treshoulds are: Vih 2.0V min. Vil 0.8V max. Voh 4.4V min. @ 50uA or 3.8V min. @ 8mA. Vol 0.1 max. @ 50uA or 0.44V @ 8mA. 5.3.2 Select the data mode: The D15 can support two different modes of operation: SoftGsm - For PC applications. RS232 full flow control - General applications. The RS232 is the default mode and no action is needed to switch to this mode. The SoftGsm require hardware connection to two lines. Down link pin should be connected via 22KOhm to ground. DSC_EN pin should be connected via 22KOhm to ground. 45 Exhibit 8 APPLICANT: MOTOROLA, INC. FCC ID: IHDT6AC1 5.4 SIM lines consideration. The SIM card can be used in 3 different ways: Internaly in the D15, Externaly by connecting a socket in the customer application and remotly via the DCS bus. In case of externaly connection the customer concern should be for Full Type Approval that may require submittion for testing in case that the SIM lines will be longer than 10cm.
