Integration Guide  Version 0.03   EDG0100PB003  Page 5  0.03 – 4/19/05  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-E 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-E 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-E 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 0.03   EDG0100PB003  Page 6  0.03 – 4/19/05 • 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: TBD 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: TBD 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.    • 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.

The only exception is that the remote SIM lines on the main I/O connector do have additional ESD protection that should handle standard human-model contact ESD events.  Generally, ESD protection (typically TVS/Transzorb devices) should be added to all signals that leave the host board.  This includes VBAT/VCC.  Series resistors (typically 47 Ω) can also be added in series with data lines to limit the peak current during a voltage excursion.   ! Caution – It is the Integrator’s responsibility to protect the Enabler II-E from electrical disturbances and excursions that exceed the specified operating parameters.   6.7 Antenna   The Enabler II-E 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.
Integration Guide  Version 0.03   EDG0100PB003  Page 25  0.03 – 4/19/05 6.8  Control Connector Signal Descriptions and Functions  6.8.1 Input Power  The Enfora Enabler II-E module uses a single voltage source of VCC=+3.3V to 4.5V.  (exact values of the uplink currents are shown in Tables 5.3.1 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.
Integration Guide  Version 0.03   EDG0100PB003  Page 26  0.03 – 4/19/05 6.8.2   Ring Indicate   The Enabler II-E 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 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) causing the Ring line to go low for 1 second only.  Using the AT+CNMI command, the Enabler II-E can be configured to send or not to send URCs upon the receipt of SMS.  See Enfora Enabler-IIE AT Command Set Reference - EDG0100PB004MAN.

This is a hardware-controlled pin on power-up. It must be grounded momentarily or continuously to start the modem.  Subsequent signals to this pin (active high-to-low transition) will cycle power to the module.  When the modem is OFF, a high-to-low pulse of > 100 mS will turn the modem ON.  When the modem is ON, a high-to-low pulse of XXX mS will deregister from the network and turn the modem OFF.  XXX is > 100 mS and can be configured via AT Command for pulses up to 10000 mS. This input has a “weak pull-up” resistor internal to the module.  This input can be left grounded if the “RTC Sleep Function” is not required.  If RTC Sleep is required, see Section 6.8.5.

The data interface operates at CMOS level.            The Enabler II-E 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 9 Enabler II-E 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 (See AT Command Document, command AT&D).  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 0.03   EDG0100PB003  Page 33  0.03 – 4/19/05 6.9  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-E 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.  6.9.1   SIM Integration for the Enfora Enabler II-E Module  The Enabler II-E default configuration does not include an on-board SIM carrier.  Enfora provides a separate product SKU for the Enabler II-E module with the integrated SIM carrier.

Integration Guide  Version 0.03   EDG0100PB003  Page 35  0.03 – 4/19/05  7.0  Modes of Operation  GSM/GPRS/EGPRS supports many optional services and modes.  The Enfora Enabler II-E module supports the following services:  • Circuit-switched data  • Short-Message Services (SMS)  • Class B/C GPRS Functionality  • Voice communication  • EGPRS  7.1  Enabling the Transmission Modes for the GSM/GPRS/EGPRS Services  Each of the GSM/GPRS/EGPRS 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-E 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-IIE AT Command Set Reference - EDG0100PB004MAN 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-E module supports three standard vocoder compression algorithms for voice communication: Full-Rate, Enhanced Full-Rate (EFR), and Half-rate (HR) and also provides support for the Adaptive Multi-Rate (AMR) codec.  7.3 Circuit-Switched Data  In this mode, the Enfora Enabler II-E 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-E module can be configured to switch automatically to Non-Transparent mode.  This capability depends on the settings in the AT+CBST command.

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-E 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-E Module  The Enfora Enabler II-E 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-E Module   The Enfora Enabler II-E 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 10 Class of Service    8.4  EGPRS Services Supported by the Enfora Enabler II-E Module  The Enfora Enabler II-E module supports the following EGPRS (modes of operation) that must be enabled by   the operator:  • EGPRS Packet Connectivity (MO and MT) with Both Dynamic and Static IP option  • EGPRS SMS (MO and MT): uses the IP (Dynamic or Static) set by the operator  • Multiple APN Setting

Integration Guide  Version 0.03   EDG0100PB003  Page 39  0.03 – 4/19/05  9.0 Software Interface  9.1 Software Interface  The application sends commands to the Enfora Enabler II-E module via the I/O signal connector. These commands use the Enfora AT Command Set and/or Enfora’s Packet API.       The Enfora Enabler II-E module operates in one of the following modes:  • Command mode: Used for configuring the Enfora Enabler II-E 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-E 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-E 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-E Integration Toolkit.  The AT command driver of the Enfora Enabler II-E 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-E module.  • In response to the commands received from the CPE, the Enfora Enabler II-E module sends characters (AT commands) to the CPE.  • Various events can also trigger the Enfora Enabler II-E 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-IIE AT Command Set Reference - EDG0100PB004MAN.

In addition to the features already provided by the Messaging Library, the modem library maintains a modem parameter database.  In order to maintain the parameter database, the modem library requires more memory than the other libraries.  This makes the library unsuitable for some of the micro controller programming.  However, it is a good library to use by applications in a personal computer or a PDA.  It allows the programmer to develop host applications for the modem quickly.
Integration Guide  Version 0.03   EDG0100PB003  Page 45  0.03 – 4/19/05 10.0 Setup and Initialization  10.1 General Setup  The data modem is controlled through the Modem RS232 port on the development board.  Connect a nine pin straight through serial cable from the Modem RS232 connector to the serial port on the controlling computer.  Hook up power supply, connect antenna, and install SIM into modem.  10.1.1  HyperTerminal Configuration for Enabler II-E  The following provides an example for setting up a Windows HyperTerminal session that can be used to experiment with various configurations on the Enabler II-E for controlling computer:  1. Select the connection interface, Direct to Com 1 (or whatever port is the serial port).   Figure 17 HyperTerminal Definition
Integration Guide  Version 0.03   EDG0100PB003  Page 46  0.03 – 4/19/05  2. Configure the COM port as displayed below.  Figure 18 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-E module is designated as:  Entry  • The data exchange from the Enfora Enabler II-E 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 0.03   EDG0100PB003  Page 47  0.03 – 4/19/05 10.1.3  Initial Response to the AT Command  After power is applied to the Enfora Enabler II-E 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-E module responds with one of the following result codes:  • OK signifies that the Enfora Enabler II-E module is ready, that it correctly interprets the AT command, and that it has executed the command.  • ERROR signifies that the Enfora Enabler II-E 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-E 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-E 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-E Module       The following example sequence provides the AT command and response for setting the Enfora Enabler II-E module for full phone functionality, automated operator selection, 9600 baud, non-transparent mode.

Integration Guide  Version 0.03   EDG0100PB003  Page 49  0.03 – 4/19/05 11.0 Integration and Testing  The Enfora Enabler II-E 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-E 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:    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-E 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-E 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-E 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-E 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-E module when tied low. Audio/Microphone Interface Preliminary balancing on Enfora Enabler II-E module. Maximum length TBD
