Integration Guide Version 1.07 GSM0100PB001 Page 4 1.07 - 1/9/04 1.0 Safety Precautions 1.1 Important Safety Information The following information applies to the devices described in this manual. Always observe all standard and accepted safety precautions and guidelines when handling any electrical device. • Save this manual: it contains important safety information and operating instructions. • Do not expose the Enfora Enabler II-G product to open flames. • Ensure that liquids do not spill into the devices. • Do not attempt to disassemble the product: Doing so will void the warranty. With the exception of the Subscriber Identification Module (SIM), this product does not contain consumer-serviceable components. 2.0 Regulatory Compliance FCC 2.1 Integration Considerations and Installation Requirements The Enabler II-G OEM GPRS modem is designed for use in a variety of host units, "enabling" the host platform to perform wireless data communications. However, there are certain criteria relative to integrating the modem into a host platform such as a PC, laptop, handheld or PocketPC, monitor and control unit, etc. that must be considered to ensure continued compliance with FCC compliance requirements. • In order to use the Enabler II-G without additional FCC certification approvals, the installation must meet the following conditions: • For the transmitter to meet the MPE categorical exclusion requirements of 2.1091, the ERP must be less than 1.5 watts for personnel separation distance of at least 20 cm (7.9 in). Therefore, the maximum antenna gain cannot exceed +3.3dBi. If greater than 1.5 watts exists, then additional testing and FCC approval is required. • If used in a "portable" application such as a handheld device with the antenna less than 20 cm (7.9 in.) from the human body when the device is operating, then the integrator is responsible for passing additional "as installed" testing: • SAR (Specific Absorption Rate) testing, with results submitted to the FCC for approval prior to selling the integrated unit. If unable to meet SAR requirements, then the host unit must be restricted to "mobile" use (see below). • Unintentional emissions, FCC Part 15; results do not have to be submitted to the FCC unless requested, although the test provides substantiation for required labeling (see below).
Integration Guide Version 1.07 GSM0100PB001 Page 5 1.07 - 1/9/04 • If used in a "mobile" application where the antenna is normally separated at least 20 cm (7.9 in) from the human body during device operation, then an appropriate warning label must be placed on the host unit adjacent to the antenna. The label should contain a statement such as the following: WARNING RF exposure. Keep at least 20 cm (7.9 in) separation distance from the antenna and the human body. • Host unit user manuals and other documentation must also include appropriate caution and warning statements and information. • If the FCCID for the modem is not visible when installed in the host platform, then a permanently attached or marked label must be displayed on the host unit referring to the enclosed modem. For example, the label should contain wording such as: Contains GSM/GPRS modem transmitter module FCC ID: MIVGSM0108 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. or Contains FCC ID: MIVGSM0108 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Substitute MIVGSM0108 for the quad-band modem label. • Any antenna used with the modem must be approved by the FCC or as a Class II Permissive Change (including MPEL or SAR data as applicable). The "professional installation" provision of FCC Part 15.203 does not apply. • The transmitter and antenna must not be co-located or operating in conjunction with any other antenna or transmitter. Violation of this would allow a user to plug another transmitter in to the product and potentially create an RF exposure condition. WARNING The transmitter and antenna must not be collocated or operating in conjunction with any other antenna or transmitter. Failure to observe this warning could produce an RF exposure condition.

Each antenna direct connect solder pad is 1.02 x 2.54 MM. 6.6.1 Antenna Solder Pads Pads are provided to solder a cable or antenna directly to the Enabler II-G board. 6.6.2 RF Connector The Enabler II-G utilizes an ultra Miniature Coaxial Interconnect from Sunridge (MCB-ST-00T) as the on-board antenna connector. A compatible mating connector is the Sunridge MCB2-xx-xx-xxx-x series component. The cable assembly is made to order. Maximum stack height of cable connector and PCB connector is 2.0 mm. 6.7 Control Connector Signal Descriptions and Functions 6.7.1 Input Power The Enfora Enabler II-G module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the uplink currents are shown in Tables5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The VCC lines (pins 1 to 6) should be connected on the application board. The uplink burst will cause strong ripple on the voltage lines and should be effectively filtered. It is recommended that 1000 to 2000 uF of capacitance be placed as close to the modem I/O connector as possible. It should be noted that the input voltage level should not drop below the minimum voltage rating under any circumstances, especially during the uplink burst period. 50 Ground R GND Electrical power return for digital and analog grounds. 51 Serial Transmit Data 3 I TXD_RADIO Serial Data from Host. 52 SIM I/O I/O SIM_IO SIM I/O Data. 53 Request To Send 7 I RTS_RADIO RTS Signal from Host. 54 SIM Reset O SIM_RST SIM Reset. 55 Clear To Send 8 O CTS_Radio CTS Signal to Host. 56 ADC1 I ADC1 Analog-to-Digital Converter Input 1. 0 – 1.75 Vdc range. 1.709 mV resolution. 10 bit. 57 Data Terminal Ready 4 I DTR_RADIO DTR Signal to Host. 58 SIM Power O SIM_VCC SIM Power. 59 Ground R GND Electrical power return for digital and analog grounds. 60 Ground R GND Electrical power return for digital and analog grounds.
Integration Guide Version 1.07 GSM0100PB001 Page 27 1.07 - 1/9/04 6.7.2 Ring Indicate The Enabler II-G module is capable of using the Ring line to discern the type of incoming call. The indicator can be monitored via a hardware line available on the 60 pin I/O signal connector. The Ring Indicator pin is #49. The function of the Ring line depends on the type of the call received. When the module is receiving a voice call, the Ring line goes low for 1 second and high for another 2 seconds. Every 3 seconds the ring string is generated and sent over the Receive (Data Out) (Rx) line. If there is a call in progress and call waiting is activated for a connected handset or hands free device, the Ring pin switches to ground in order to generate acoustic signals that indicate the waiting call. When a Fax or data call is received, Ring goes low and will remain low. Every 3 seconds a ring string is generated and sent over the Receive (Data Out) (Rx) line. An incoming SMS can be indicated by an Unsolicited Result Code (URC) which causes the Ring line to go low for 1 second only. Using the AT+CNMI command, the Enabler II-G can be configured to send or not to send URCs upon the receipt of SMS. See Enfora GSM/GPRS OEM Module AT Command Set Reference - GSM0102PB001MAN.

Use large value pull-up resistor (up to 1 MΩ) to Vcc (Power Input/Batt). 6.7.4 Serial Interface (9 Pin I/F) (See table in section 6.5.1 I/O Connector Pin Assignments) The modem provides a standard 16550 UART serial interface to the host. The data interface operates at CMOS level. The Enabler II-G is designed to be used like a DCE device. RxData is the serial data from the modem to the host. TxData is the serial data from the host to the modem. Figure 10 Enabler II-G Serial Interface This data may contain 7 or 8 data bits, 1 or 2 stop bits, even/odd/no parity bits. The baud rate may be adjusted to 75, 150, 300, 1200, 2400, 4800, 9600,19200, 38400, 57600, or 115200 bits per second. Default settings are 8 data, 1 stop, no parity, and 115200 baud. DTR may be used to force the modem into AT command mode from online data mode. RTS and CTS may be used for hardware handshaking. DSR is always active (connected to ground) while the modem is on. RING may be used to alert the host to a variety of incoming calls. For a minimal implementation, connect RxData and TxData to the COM port serial data lines, connect DTR and RTS to GND.

Integration Guide Version 1.07 GSM0100PB001 Page 32 1.07 - 1/9/04 6.8 Subscriber Identity Module (SIM) Carrier The SIM, an integral part of any GSM terminal device, is a “smart card” that is programmed with subscriber information: • The user information consists of an International Mobile Subscriber Identity (IMSI) number, which is registered with the GSM provider, and an encryption Ki (pronounced "key"). This information consists of a microprocessor and memory installed on a plastic card. Note: The SIM is not provided with the Enfora Enabler II-G module. The SIM must be obtained from the GSM service provider and must be provisioned by the operator for data and/or voice. Always take care to protect the SIM: the GSM terminal will not operate without the SIM installed. The SIM provides the IMSI for authentication. To gain access to the GSM network, the network must recognize the IMSI number, and the terminal must be able to properly decrypt the data sent by the network. The SIM also serves as a buffer for SMS messages, storing the message for transmission until a radio link is available and buffering received messages until retrieved. 6.8.1 SIM Integration for the Enfora Enabler II-G Module The Enabler II-G default configuration does not include an on-board SIM carrier. Enfora provides a separate product SKU for the Enabler II-G module with the integrated SIM carrier.
Integration Guide Version 1.07 GSM0100PB001 Page 33 1.07 - 1/9/04 6.8.2 Using a Remote SIM with the Enfora Enabler II-G Module The Enabler II-G default configuration does not include an on-board SIM carrier. If the module is going to be integrated using a remote SIM, the following guidelines are provided: • To utilize a remote SIM, the integrator must provide a suitable SIM connector on the Application. • The maximum distance from the Enabler II-G to the remote SIM connector must not exceed 25.4 cm (10 inches).

Integration Guide Version 1.07 GSM0100PB001 Page 34 1.07 - 1/9/04 7.0 Modes of Operation GSM/GPRS supports many optional services and modes. The Enfora Enabler II-G module supports the following GSM/GPRS services: • Circuit-switched data • Short-Message Services (SMS) • Class B GPRS Functionality • Voice communication 7.1 Enabling the Transmission Modes for the GSM/GPRS Services Each of the GSM/GPRS services has two modes that can be enabled separately: • Mobile-originated (MO): allows the making of a service request (such as, making a telephone call or sending an SMS) • Mobile-terminated (MT): allows receiving a service request (such as receiving a telephone call or an SMS) Note: Contact your local GSM operator to ensure that the services and modes have been provisioned for the SIM. 7.2 Voice Communication The Enfora Enabler II-G module has full voice capabilities, provided the necessary connections have been made for the speaker and microphone pins on the 60-pin I/O connector. The Enfora Enabler-G AT Command Set Reference - GSM0102PB001MAN has the entire list of commands that can be used to control the voice functionality. The quick start guide in this manual provides a basic command set that can be used to initialize and test the voice functionality. The Enfora Enabler II-G module supports three vocoder compression algorithms for voice communication: Full-Rate, Enhanced Full-Rate (EFR), and Half-rate (HR). 7.3 Circuit-Switched Data In this mode, the Enfora Enabler II-G module supports both of the connection modes of transmission that are provided by GSM: • Non-Transparent mode delivers a constantly low error rate but with a non-guaranteed throughput or delay. The Non-Transparent service provides a performance that is closest to using a modem over a fixed Public Switched Telephone Network (PSTN) line. Note: All GSM service providers may not support Transparent mode. In those cases, the Enfora Enabler II-G module can be configured to switch automatically to Non-Transparent mode. This capability depends on the settings in the AT+CBST command.
Integration Guide Version 1.07 GSM0100PB001 Page 35 1.07 - 1/9/04 7.4 SMS: Short Message Services • Short Message Services (SMS) is a feature-rich GSM service. The Enfora Enabler II-G module can perform the following tasks: • Sending and receiving binary messages of up to 160 characters (7-bit characters) • Sending and receiving text messages of up to 140 bytes (8-bit data) • Submitting a SMS Protocol Data Unit (PDU) to a SMSC (Short Message Service Center) and storing a copy of the PDU until either a report arrives from the network or a timer expires • Receiving a SMS PDU from a SMSC • Returning a delivery report to the network for a previously received message • Receiving a report from the network • Notifying the network when the module has sufficient memory capacity available to receive one or more SMS messages (after the module had previously rejected a message because its memory capacity was exceeded) 7.5 SMS Features Supported by the Enfora Enabler II-G Module The following list details the key characteristics and assumptions regarding the form of SMS supported in the Enfora Enabler II-G module. • Supports both mobile-originated (MO) and mobile-terminated (MT) SMS • Delivers the message to a telephone • Supports 8-bit data • Supports Message Class 1 & Class 2 • Provides a status report indicator • Allows the definition of a validity period • Provides the Service Center Time Stamp • Alerts the SMSC • USSD
Integration Guide Version 1.07 GSM0100PB001 Page 36 1.07 - 1/9/04 8.0 SIM Operation 8.1 Provisioning the SIM The SIM can support optional features or services. Most operators typically configure the SIM to send/receive voice calls and to receive SMS; however, some may require an additional tariff to enable the SIM to send SMS. The transmission of circuit switched and GPRS data are also additional services that may be required to allow the service: • Mobile-originated (MO): allows making a service request (such as, making a call or sending an SMS) • Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone call or an SMS) It is imperative for the Enfora Enabler II-G module that the SIM be configured for the optional services that are required for the application. 8.2 GSM Services Supported by the Enfora Enabler II-G Module The Enfora Enabler II-G module supports four GSM services (modes of operation) that must be enabled by the operator: • Voice calls (MO and MT): requires a telephone number • SMS (MO and MT): uses the telephone number for Voice • Circuit-switched data calls (MO and MT): requires a telephone number • The GSM SIM can have multiple telephone numbers. 8.3 GPRS Services Supported by the Enfora Enabler II-G Module The Enfora Enabler II-G module supports the following GPRS (modes of operation) that must be enabled by the operator: • GPRS Packet Connectivity (MO and MT) with Both Dynamic and Static IP option • GPRS SMS (MO and MT): uses the IP (Dynamic or Static) set by the operator • Multiple APN Setting • Quality of Service Options • Multi-slot 12 Class of Service (Requested vs Granted) (Demonstrated @ MS10)

Integration Guide Version 1.07 GSM0100PB001 Page 38 1.07 - 1/9/04 9.0 Software Interface 9.1 Software Interface The application sends commands to the Enfora Enabler II-G module via the 60-pin I/O signal connector. These commands use the Enfora AT Command Set and/or Enfora’s Packet API. The Enfora Enabler II-G module operates in one of the following modes: • Command mode: Used for configuring the Enfora Enabler II-G module, for interrogating the GSM network, and for placing and receiving calls. It uses the AT command set via the serial port for communication. • On-line mode: Used after a circuit-switched data call has been established. Data is passed between the Enfora Enabler II-G module and the controlling application without command interpretation. The only AT command that is interpreted in On-line mode is the +++ command. (This command places the Enfora Enabler II-G module in Command mode but does not terminate the circuit-switched data call.) • IP Packet /API Mode: Used to read/write modem parameters, interrogate network information, and place and receive calls in real-time, multi-tasking mode. The Packet API mode is facilitated over a PPP connection and the packets can be constructed according to the information provided in the Enfora GSM-GPRS Family UDP-API Reference GSM0102PB002MAN. Enfora GSM-GPRS Family Modem Control Library Reference GSM0000PB006MAN provides detail of the UDP Modem Control Library that has three levels: port , messaging, and modem libraries. Each of the three levels contains one or more libraries. For example, the port libraries layer has UDP PPP Port, UDP Socket Port, and COM Port libraries. All libraries are provided as a part of the Enfora Enabler II-G Integration Toolkit. The AT command driver of the Enfora Enabler II-G module never exits the Command state, that is, it never enters the On-line mode. Although the host interface may not be able to access the AT command interpreter, it is always running and is available via the API Mode over a PPP connection and/or via the RF interface. • In the Command state, characters that are received from the Customer Premise Equipment (CPE) are treated as AT commands by the Enfora Enabler II-G module. • In response to the commands received from the CPE, the Enfora Enabler II-G module sends characters (AT commands) to the CPE. • Various events can also trigger the Enfora Enabler II-G module to send characters (AT commands) to the CPE. 9.2 Format for the AT Commands The general format of the command line is: <prefix> <command> <CR> <prefix> AT <command> See AT Command Manual <CR> 0X0D The prefix AT obtains synchronization, identifies the character parameters, and indicates that a command may be in the following characters. AT commands are not case sensitive: use either capital letters or lower-case letters for the AT command. Note: Some AT Command parameter values ARE case sensitive and are documented in the Enfora Enabler-G AT Command Set Reference - GSM0102PB001MAN.

Integration Guide Version 1.07 GSM0100PB001 Page 45 1.07 - 1/9/04 2. Configure the COM port as displayed below. Figure 19 COM Port Settings 10.1.2 Initialization (AT Command Interface) In the GSM vocabulary, a call from GSM mobile to the PSTN is called a "mobile-originated call" or "outgoing call". A call from the fixed network to a GSM mobile is called a "mobile-terminated call" or "incoming call." In the following examples, “Entry” refers to the application. The following convention describes the direction of the data exchange: • The data exchange from the customer application to the Enfora Enabler II-G module is designated as: Entry • The data exchange from the Enfora Enabler II-G module to the customer application is designated as: Response Note: With the exception of the +++ command (Online Escape Sequence), all commands must be preceded by the AT attention code (or command prefix) and terminated by pressing the <CR> character. In the following examples, the <CR> and <CR><LF> are intentionally omitted for clarity and space.
Integration Guide Version 1.07 GSM0100PB001 Page 46 1.07 - 1/9/04 10.1.3 Initial Response to the AT Command After power is applied to the Enfora Enabler II-G module, the module performs a power-up self-test. The self-test completes within one (1) second. When queried with the AT command, the Enfora Enabler II-G module responds with one of the following result codes: • OK signifies that the Enfora Enabler II-G module is ready, that it correctly interprets the AT command, and that it has executed the command. • ERROR signifies that the Enfora Enabler II-G module does not understand the command or that the command is invalid. Entry AT Response OK Command valid: module is ready The Enfora Enabler II-G module must be in AT Command mode (please refer to section 10.3 GPRS Packet Examples for packet mode initialization and setup) when any command is entered (with the exception of the online escape sequence). Commands entered when the module is in On-line mode are treated as data, and are transmitted as such to the receiving module. i.e. If the module is in PPP or SLIP mode, AT commands cannot be entered. 10.1.4 Sending an Initialization String to the Enfora Enabler II-G Module The following example provides the sample AT commands and responses for the following initialization tasks: • Reset the module to the factory defaults • Disable character echo • Transmit Result Codes • Set the module to Verbose mode (to display result codes as words) • Set the DCD to match the state of remote modem • Ignore the DTR Entry AT&FE0Q0V1&C1&d0 Initialization string Response OK Command is valid Entry ATSO=1 Auto answer on 1st ring Response OK Command is valid 10.1.5 Setting Up the Communication Mode for the Enfora Enabler II-G Module The following example sequence provides the AT command and response for setting the Enfora Enabler II-G module for full phone functionality, automated operator selection, 9600 baud, non-transparent mode.

Integration Guide Version 1.07 GSM0100PB001 Page 48 1.07 - 1/9/04 11.0 Integration and Testing The Enfora Enabler II-G module has been designed to minimize the amount of time required for integration and testing the application. By being fully certified by the appropriate bodies, the Enfora Enabler II-G module provides seamless integration into the GSM network. The integration issues for the application can be narrowed to the utilization of the AT commands and the use of the GSM functionality. Coverage and signal quality may be evaluated by using the RSSI commands. Additional network information can be determined by using AT commands. Integration of the GPRS Packet capabilities is more complicated than using AT command sequences to initiate the connection and begin transferring data. The following Application Notes should be used to integrate the GPRS packet capabilities: GSM0000AN001 - Enabler-G PPP Configuration for Windows 98 GSM0000AN002 - Enabler-G PPP Configuration for Windows 2000 GSM0000AN008 - Enabler-G PPP Configuration for Windows XP GSM0000AN010 - Enabler-G PPP Configuration for PocketPC 2002 GSM0000AN005 - Enabler-G Automated Network Connection Configuration and Use Integrating the Enfora Enabler II-G Module Note: Generally, all interfaces that are externally available to the end user need to be ESD-conditioned and terminated in some way. Many of these interfaces should not be connected with power applied. At the highest level, this is done using some type of GSM test equipment (such as, Racal 6103E), a computer, and a serial interface tester. The GSM test equipment must be able to simulate a GSM call and measure the key parameters related to the module. Additionally, the serial interfaces and some minimal SIM functionality can be verified by sending AT commands to the Enfora Enabler II-G module. All of these conditions need to be verified at ambient as well as extreme conditions. As part of integration, each of the following interfaces must be verified: Information Recommendations SIM The maximum line length of the SIM interface is 25.4 cm (10 inches). The Enfora Enabler II-G module takes care of the signal conditioning As a minimum, an external application with a remote SIM will require a standard SIM carrier. Filter the SIM VCC signal with a 10 uf / 10 V capacitor to help with the line length. Primary and secondary serial Interfaces The Enfora Enabler II-G module uses a 3 V digital interface. The RS-232 signals must be level-shifted to get standard levels. These signals must be ESD-protected. Reset Interface Resets the Enfora Enabler II-G module when tied low. Audio/Microphone Interface Preliminary balancing on Enfora Enabler II-G module. Maximum length TBD

Furthermore, this label must be visible to and easily readable by all persons in the immediate vicinity of the antenna WARNING To comply with FCC RF exposure requirements, a separation distance of 20 cm (7.87”) or more must be maintained between this antenna and all persons Human Exposure Compliance Statement Include the following statement in the instruction / operation manual. Enfora certifies that the Enfora Enabler II-G ™ MHz GSM Radio Module (FCC ID: MIVGSM0107 or MIVGSM0108) complies with the RF hazard requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart E of the FCC Rules and Regulations. This certification is contingent upon installation, operation and use of the Enfora Enabler II-G and its host product in accordance with all instructions provided to both the OEM and end used. When installed and operated in a manner consistent with the instructions provided, the Enfora Enabler II-G meets the maximum permissible exposure (MPE) limits for general population / uncontrolled exposure at defined in Section 1.1310 of the FCC Rules and Regulations.
Integration Guide Version 1.07 GSM0100PB001 Page 57 1.07 - 1/9/04 Specific OEM Responsibilities for Portable Products and Applications Each device or product, into which the Enfora Enabler II-G PCS-1900 GSM transceiver has been incorporated, and which is intended to be used in an application that meets the definition of "portable" MUST be separately authorized by the FCC for the purposes of determining compliance with current FCC guidelines limiting human exposure to radio frequency radiation. Portable devices must be evaluated for RF exposure based on Specific Absorption Rate (SAR) limits; further information on such evaluations are available from the FCC via the Internet. Specific OEM Responsibilities for Mobile Products and Applications Separate or additional FCC approvals are NOT required for devices or products, into which the Enfora Enabler II-G PCS-1900 GSM transceiver has been incorporated, that are used in applications that meet the definition of "mobile." For all end products, the OEM or integrator must provide instructions, warnings and labels to ensure that the product complies with current FCC guidelines limiting human exposure to radio frequency radiation. Current FCC regulations limit the EIRP of mobile devices to 2 W. Because the nominal RF output power of the Enfora Enabler II-G PCS-1900 GSM transceiver is 1.0 W (30 dBm), antenna gain for mobile products and applications cannot exceed 3 dBi. Specific OEM Responsibilities for Fixed Products and Applications Separate or additional FCC approvals are not required for devices or products, into which the Enfora Enabler II-G GSM transceiver has been incorporated, that are used in applications that meet the definition of "fixed.” For all end products, the OEM or integrator must provide the instructions, warnings and labels to ensure that the product complies with current FCC guidelines limiting human exposure to radio frequency radiation. Separate or additional FCC approvals are required for devices or end products used in fixed applications where antenna gain in excess of 7dBi is desired. Nationally Recognized Testing Laboratory (NRTL) Approval The Enfora Enabler II-G module has been tested by an NRTL and approved as a component for incorporation into OEM products. The final product and application that incorporates the Enfora Enabler II-G module will require separate verification of product safety approval.
