 GSM0128IG001  5  Revision Draft – 9/22/08 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 IIG 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 IIG 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 IIG without additional FCC certification approvals, the installation must meet the following conditions:    Maximum RF output power and antenna gain to meet Maximum Permissible Exposure Requirements: GSM850 mode:  Power at antenna port is +33 dBm.  The maximum gain is 1.4 dBi. GSM1900 mode:  Power at antenna port is 30 dBm.  The maximum gain is 7 dBi in order to meet the requirements of maximum 2 watts EIRP for mobile transmitters. If RF power and/or antenna gain is desired, a separate FCC certification is required.    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).
 GSM0128IG001  6  Revision Draft – 9/22/08   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: MIVGSM0128 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: MIVGSM0128 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.

 GSM0128IG001  17  Revision Draft – 9/22/08  4.7 General layout guidelines for Enfora GSM modules  To ensure lowest possible EMI emission, maximum thermal conduction and mechanical integrity, all metal tabs on the GSM module shield must be soldered down on to a continuous ground plane. The PCB trace that feeds the RF output port should be 50ohm characteristic impedance, coplanar, or routed into internal layers to keep the top layer continuous around and underneath the device. Provide ample ground vias around metal tabs, the RF trace and launch pad. If possible, keep I/O and power traces away from the RF port.

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/Transorb devices) should be added to all signals that leave the host board.  This includes VBAT/VCC.  Series resistors (typically 47 ) 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 IIG from electrical disturbances and excursions that exceed the specified operating parameters.   6.7 Antenna  A custom tri-band antenna can be attached via the on-board connector or soldered directly to the modem.  Each antenna direct-connect solder pad is 1.02 x 2.54 mm.   6.7.1  Antenna Solder Pads  Pads are provided to solder a cable or antenna directly to the Enabler IIG board.
 GSM0128IG001  28  Revision Draft – 9/22/08 6.7.2 RF Connector  The Enabler IIG utilizes an 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.  6.8 Control Connector Signal Descriptions and Functions  6.8.1 Input Power  The Enfora Enabler IIG 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.
 GSM0128IG001  29  Revision Draft – 9/22/08 6.8.2   Ring Indicate (Pin 49)  The Enabler IIG 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 three (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 IIG can be configured to send  or not to send URCs upon the receipt of SMS.  See Enfora GSM0128AT001 – Enfora Enabler IIG AT Command Set.

 GSM0128IG001  30  Revision Draft – 9/22/08 6.8.3  Radio Power/Reset (Pin 22)   The Reset signal is used to force the modem to start at a known state. When the Reset is pulled low the modem will immediately suspend any function and will not exit the reset state until the Reset signal is released to be pulled high. Once the transition from low to high is complete, the modem will boot. The Reset signal is falling edge triggered, so the reset function is set immediately when the signal is pulled low.  When using Reset, it will immediately detach the connection from the GSM network although this is not considered ideal. Typically during a normal shutdown, the modem will issue a detach request to the network to indicate that it is being removed. Reset must not be used to “power off” the device, but only as a last resort wherein there is no response from the module.  Controlling the Reset signal must only performed by an open collector/open drain device. Driving the Reset signal high will interfere with the normal operation of the modem power on/off sequences. Power sequencing cannot be guaranteed if Reset is being driven high by an external device. If driving from an external microprocessor, the reset can be controlled by driving the control pin low as an output, then change the pin control to be an input, this will satisfy the high impedance requirement.  The Reset pin can also be monitored as a system on/off indication. When the modem is powered on during a normal operating state,  this pin will be set high. When the modem is powered down or in the “off” state, this pin will be low. Any monitoring circuit MUST be high impedance, such as a logic gate or microprocessor input.

A failing-edge on this Active-Low input will switch ON the module or switch OFF the module after a delay*. 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, then the PWR_CTL line must be floated to allow the internal resistor to pull the line high.   Controlling the Power Control signal must only be performed by an open collector/open drain device. Driving the Power Control signal high may interfere with the normal operation of the modem. If driving from an external microprocessor, the Power Control can be controlled by driving the control pin low as an output, then change the microprocessor’s pin control to be an input (this will satisfy the high impedance requirement).
 GSM0128IG001  31  Revision Draft – 9/22/08                        6.8.4.1  Turning ON the Enabler IIG   Pulling the PWR_CTL line on the Enabler IIG LOW for at least 50ms (after Vbat is applied and stabilized) is required to turn it ON. Section 6.8.43 describes various ways to provide the signal.  Do not use a pull-up resistor on the PWR_CTL line since the line is pulled up internal to the modem.  6.8.4.2  Turning OFF the Enabler IIG  The Enabler IIG can be turned OFF by either a low pulse on the PWR_CTL line or, or by a software command (ATt$OFF - see AT command guide for further information). Section 6.8.4.3 describes various ways to provide the signal.    6.8.4.3  Using the Power Control Signal    Typical use powering module on/off with a switch:     Figure - 9 - Power Control Switch      ! *The OFF Delay is controlled by the AT$OFFDLY command. A value of 0 disables the PWR_CTL line from turning the module off. 0 is the default value.  To enable the module to switch-OFF via PWR_CTL one must set AT$OFFDLY to a value other than 0. The valid range is 100 to 1000 milliseconds.
 GSM0128IG001  32  Revision Draft – 9/22/08    Typical use controlling PWR_CTL from a microcontroller:       Typical connection of PWR_CTL to modem:        This next figure shows a typical connection to the Enabler IIG module in a machine-to-machine application using the external PWR_CTL signal, when there is not an external processor controlling the power on/off states. The RTC deep sleep functions will NOT function since the PWR_CTL pin is tied low, the processor will never stay in a “RTC Sleep” mode. To reset the module, either the RESET pin is toggled or power (VBAT) must be cycled.
 GSM0128IG001  33  Revision Draft – 9/22/08    Figure 10 – External Power Control Signal (no external processor)  Figure 10 shows a typical connection from an external processor to the Enabler IIG module, using the external PWR_CTL signal.  The Enabler IIG can be powered on by using the PWR_CTL signal, and  reset with the RESET signal.  When using the PWR_CTL, the I/O or serial lines can be at any voltage state desired.  It is recommended that the I/O and serial lines be tri-stated or set low when the modem is shutdown for an extended period of time to prevent any leakage of current from the processor to the modem.

This mode will NOT allow for the RTC sleep to function.  Figure 14 - Power On/Off using Power Control Signal tied to Ground
 GSM0128IG001  37  Revision Draft – 9/22/08 6.8.7  Serial Interface (9 Pin I/F) (Pins 41, 43, 45, 47, 49, 51, 53, 55, 57)  The modem provides a standard 16550 UART serial interface to the host.  The data interface operates at CMOS level.  The Enabler IIG 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 15 - Enabler IIG 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 , 300, 600, 1200, 2400, 4800, 7200, 9600, 14400, 19200, 28800, 33900, 38400, 57600, ,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, and connect DTR and RTS to GND.  The electrical characteristics for the I/O lines are the same as the General Purposes Input/Output (GPIO) lines. RING CTS DTR DSR RTS Rx Tx Enabler IIG UART DCD Host

 GSM0128IG001  42  Revision Draft – 9/22/08 6.10  Subscriber Identity Module (SIM) Carrier (Pins 48, 52, 54, 55)  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 IIG 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.   6.10.1   SIM Integration for the Enfora Enabler IIG Module  The Enabler IIG default configuration does not include an on-board SIM carrier.  Some versions may include an on-board SIM carrier. Enfora provides a separate product SKU for the Enabler IIG module with the integrated SIM carrier.
 GSM0128IG001  43  Revision Draft – 9/22/08 6.10.2   Using a Remote SIM with the Enfora Enabler IIG Module  Although some versions may include it, the Enabler IIG 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 IIG to the remote SIM connector must not exceed 25.4 cm (10 inches).

 GSM0128IG001  44  Revision Draft – 9/22/08  7.0  Modes of Operation  GSM/GPRS supports many optional services and modes.  The Enfora Enabler IIG module supports the following   GSM/GPRS services:    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 IIG 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 GSM0128 AT Command Doc 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 IIG module supports three vocoder compression algorithms for voice communication: Full-Rate, Enhanced Full-Rate (EFR), Adaptive Multi Rate (AMR), and Half-rate (HR).
 GSM0128IG001  45  Revision Draft – 9/22/08 7.3 SMS: Short Message Services    Short Message Services (SMS) is a feature-rich GSM service.  The Enfora Enabler IIG 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)  7.4 SMS Features Supported by the Enfora Enabler IIG Module  The following list details the key characteristics and assumptions regarding the form of SMS supported in the Enfora Enabler IIG module.   Supports both mobile-originated (MO) and mobile-terminated (MT) SMS    Delivers the message to a telephone    Supports 8-bit data    Supports Message Class 0, 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
 GSM0128IG001  46  Revision Draft – 9/22/08  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 IIG 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 IIG Module  The Enfora Enabler IIG 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    The GSM SIM can have multiple telephone numbers.   8.3 GPRS Services Supported by the Enfora Enabler IIG Module  The Enfora Enabler IIG 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
 GSM0128IG001  47  Revision Draft – 9/22/08 8.4 Selecting the Modes of Operation  When provisioning the SIM for the Enfora Enabler IIG module, enable the following modes of operation:    Voice calls: configure the SIM for both MO and MT service (to send and receive)    SMS: configure the SIM either for MT alone (to receive) or for both MO and MT (to send and receive)   Voice  SMS  GPRS  Function MO/MT  MT   Voice calls, receive SMS, make data calls MO/MT  MO/MT  Voice calls, receive / send SMS, make data calls MO/MT  MO/MT  Voice calls, receive / send SMS, make / receive data calls (requires an additional data telephone number)
 GSM0128IG001  48  Revision Draft – 9/22/08  9.0 Software Interface  9.1 Software Interface  The application sends commands to the Enfora Enabler IIG 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 IIG module operates in one of the following modes:    Command mode: Used for configuring the Enfora Enabler IIG module, for interrogating the GSM network, and for placing and receiving calls.  It uses the AT command set via the serial port for communication.    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 GSM0308UG001 - Enfora GSM-GPRS Family API Reference.  GSM0308UG001 - Enfora GSM-GPRS Family API Reference 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 IIG Integration Toolkit.  The AT command driver of the Enfora Enabler IIG 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 IIG module.    In response to the commands received from the CPE, the Enfora Enabler IIG module sends characters (AT commands) to the CPE.    Various events can also trigger the Enfora Enabler IIG 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 GSM0128AT001 – Enfora Enabler IIG AT Command Set.
 GSM0128IG001  49  Revision Draft – 9/22/08  9.3 Enfora AT Command Set  For a full description of the AT commands, refer to the GSM0128AT001 – Enfora Enabler IIG AT Command Set.  Note: A command description that includes an *asterisk denotes that the GSM service provider must enable supplementary services functionality before the command is available.  9.4 Enfora Packet Application Programming Interface  9.4.1 UDP-API Architecture  The following information provides an overview of the Enfora UDP-based API architecture.  Full details are provided in the GSM0308UG001 - Enfora GSM-GPRS Family API Reference.    Figure 18 provides the general structure for the UDP-API.

 GSM0128IG001  50  Revision Draft – 9/22/08 The following provides information related to the general construction of the UDP-API packet.  Other command structures are available and can be found in the API reference manual.    All AT commands listed in the GSM0128AT001 – Enfora Enabler IIG AT Command Set document are supported via this method.  To send an AT command via DUN or OTA, the user has to follow the following message structure.  This message structure sends the ATI command to the modem and receives Enfora, Inc. response from the modem.

UART DriverPort LibraryHost Control InterfaceMessaging LibraryModem LibraryHost ApplicationHost Modem  Figure 22 - Using Modem Library Modem Library provides the most complete modem access services.  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.
 GSM0128IG001  54  Revision Draft – 9/22/08  10.0 Setup and Initialization  10.1 General Setup  The GPRS 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 IIG  The following provides an example for setting up a Windows HyperTerminal session that can be used to experiment with various configurations on the Enabler IIG for controlling computer:  1. Select the connection interface, Direct to Com 1 (or whatever port is the serial port).   Figure 23 - HyperTerminal Definition
 GSM0128IG001  55  Revision Draft – 9/22/08  2. Configure the COM port as displayed below.   Figure 24 - 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 IIG module is designated as:  Entry    The data exchange from the Enfora Enabler IIG 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.
 GSM0128IG001  56  Revision Draft – 9/22/08 10.1.3  Initial Response to the AT Command  After power is applied to the Enfora Enabler IIG 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 IIG module responds with one of the following result codes:    OK signifies that the Enfora Enabler IIG module is ready, that it correctly interprets the AT command, and that it has executed the command.    ERROR signifies that the Enfora Enabler IIG module does not understand the command or that the command is invalid.  Entry  AT  Response  OK  Command valid: module is ready  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 IIG 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 IIG Module       The following example sequence provides the AT command and response for setting the Enfora Enabler IIG module for full phone functionality, automated operator selection, 9600 baud, non-transparent mode.    Entry AT+CFUN=1 FULL phone functionality Response  OK  Command is valid Entry AT+COPS=0 Automatic operator selection Response  OK  Command is valid Entry AT+CBST=7,0,1 9600 baud, non-transparent mode Response  OK Command is valid
 GSM0128IG001  57  Revision Draft – 9/22/08 1.1.1  11.0 Integration and Testing  The Enfora Enabler IIG 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 IIG 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 IIG 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.
