Integration Guide  Draft EDG0208IG001  Page 8  Rev. 1.03 –4/19/07 4.5 General design guidelines for utilizing Enfora GSM modules  The following guidelines are provided in an effort to allow Enabler IIE module users to successfully implement their PCB layout to obtain the best performance.  This includes the lowest possible EMI emissions, maximum thermal conduction, mechanical integrity, and voice quality.  The Enabler IIE module is a very compact, high performance design, yet it is easy to interface into the final product.  In order to realize its full potential, designers should pay close attention to ground structures, the routing of RF and Digital traces, and the size of the power supply lines.      These design tips are strictly guidelines and are not meant to be a complete list of items that guarantee  actual performance.  Each application is different and may require variation from these guidelines, however, care should be given to utilize these sound engineering principles whenever possible.
Integration Guide  Draft EDG0208IG001  Page 9  Rev. 1.03 –4/19/07 4.6 Advanced tips for an RF friendly layout  Ground Plane  To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is recommended that all metal tabs on the GSM module shield must be soldered down onto a continuous ground plane that runs under the entire module.  Ample ground vias should be provided around the metal tabs to create a low impedance ground.  It is recommended to minimize the number of I/O and power traces and vias under the GSM module to allow for as much ground plane as possible. If the integrated unit includes more than one board, the design must guarantee a good RF ground connection between the boards in order to make sure the ground planes are at the same RF potential. An example of a good ground structure and pad layout is shown below in Figure 1.   Figure 1 - Example of good ground plane for GSM modules
Integration Guide  Draft EDG0208IG001  Page 10  Rev. 1.03 –4/19/07 Thermal Relief  Because the ground plane acts as a large heat sink, it can affect the solderability of components.  A common method to reduce this effect is to use thermal relief around the pad in question.  However, great care must be taken when using thermal relief for high current or high frequency applications  For example, a large thermal relief like the one shown in Figure 2 can serve the purpose for general applications such as low current, low speed data lines, DC connections and audio frequency applications.  Such thermal relief structures should be avoided for applications where high current and/or high frequency is involved, such as those using the Enabler Module.  Depending on the frequency of operation, the long narrow thermal relief traces between the pad and the ground plane act like an RF choke.  These RF chokes become higher impedance at harmonics of the fundamental frequency making it problematic for high frequency suppression.  This can make it difficult to pass type approval testing.   Figure 2 - Example of a POOR RF Thermal Relief  If thermal relief is necessary, it is recommended that you use short, fat traces similar to those shown in Figure 3.  This will still provide a solderable connection, while providing a better RF connection.  Making them shorter also allows for a more continuous ground plane due to less copper being removed from the area.  It is also recommended to have ground vias around all thermal relief of critical ground pins such as the five Enabler shield tabs.   POOR RF thermal relief
Integration Guide  Draft EDG0208IG001  Page 11  Rev. 1.03 –4/19/07  Figure 3 - Example of a GOOD RF Thermal Relief  Antenna and RF Signal Trace  The PCB trace that feeds the RF output port must be designed for a 50 ohm characteristic impedance, coplanar, or routed into internal layers to keep the top layer continuous around and underneath the Enabler module. Ample ground vias should be provided around the RF contacts, the RF trace and launch pad. If possible, keep I/O and power traces away from the RF port.  This includes traces running parallel or orthogonal to it.  Thermal relief should not be used on the antenna output port ground pads.  The designer must pay close attention to the size of the pad and thickness of the dielectric beneath the signal pad and trace.  Most PCB manufacturers can adjust the trace width to maintain 50 ohms impedance if the traces are identified and instructions are included on the FAB drawing.  This service is typically provided at no or minimal additional cost.  For minimum RF emissions due to the fundamental frequency of operation, the Enabler module works best with an antenna load that has a VSWR of 1.5:1 or better.  The antenna should not have gain at the harmonic frequencies, otherwise, the conducted harmonics could get amplified to a point where the product no longer passes type approval.  However, for applications where antenna quality is less than ideal, it is recommended to have a low pass filter (Pi structure with N=3) in the RF path to the antenna.  This is a secondary plan should there be a need to lower harmonic levels at frequencies above the PCS band.  The pad structure may also be used to match the antenna load impedance, if required.  If it is not needed, a capacitor of low reactance may be used to bridge the Pi structure.  The RF cable going between the Enable module and the antenna is very lossy, therefore, the length of this cable should be kept as short a possible.  If multiple antennas are used in their design, care should be taken during placement selection to minimize the coupling between the GSM antenna and the other antennas.  GOOD RF thermal relief
Integration Guide  Draft EDG0208IG001  Page 12  Rev. 1.03 –4/19/07 Vbat Input  The Enabler Vbat input can have a relative high current draw that can fluctuate rapidly, especially when transmitting at max power and burst mode.  The Vbat interface must be designed to provide the required instantaneous voltage and current with minimal voltage droop.  This includes both sufficient bulk decoupling capacitance as well as adequate layout provisions.    When laying out the connections to the Enabler interface connector, it is tempting to use traces of the same width as the connector pins.  However, this is a very compact connector and traces of that width will not have sufficient copper.  Similar to the discussion on thermal relief, the use of narrow traces to connect the Vbat pins to the source voltage can act like a high impedance and cause a significant voltage droop when higher currents are required as shown in Figure 4.       Figure 4 - Example of Vbat Voltage Droop  If the Vbat drops too low, the Enabler modules will reset.  To minimize the trace loss, it is suggested to use a larger trace that spans several pins as shown in Figure 5.  Any concern about solderability can be mitigated by using solder mask with cutouts for the individual pins as shown by the blue lines in the figure.  The layout should provide sufficient trace width over the entire trace from the Enable modules all the way to the source of the Vbat voltage.  Any transitions between layers for this trace should utilize multiple vias.  Since even the best layout will have some impedance from the source to the Enabler module, sufficient bulk decoupling capacitance is required at the Vbat input to the Enabler module.  It is suggested to use at least two 1000 uF, low ESR, tantalum capacitors located very close to the Enabler interface connector Vbat pins.  Any thermal relief used on these capacitors should comply with the information given above in order to provide the lowest impedance possible.  The grounding of these capacitors is critical.  Therefore, it should be a low impedance and should utilize multiple vias to the internal ground plane close to the capacitor as well.

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 ) 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 EDG0208 from electrical disturbances and excursions that exceed the specified operating parameters.   6.6 Antenna   The Enabler EDG0208 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.

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 2500 F 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  Draft EDG0208IG001  Page 30  Rev. 1.03 –4/19/07 6.7.2 Ring Indicate   The Enabler EDG0208 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 EDG0208 can be configured to send or not to send URCs upon the receipt of SMS.  See Enfora Enabler-IIIE AT Command Set Reference - EDG0208AT001.

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.

The data interface operates at CMOS level.            The Enabler EDG0208 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 17 Enabler EDG0208 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 9600, 14400, 28800, 38400, 57600, 115200, 230400, 460800.  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.

This information consists of a microprocessor and memory installed on a plastic card.  Note:  The SIM is not provided with the Enfora Enabler EDG0208 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 EDG0208 Module  The Enabler EDG0208 default configuration does not include an on-board SIM carrier.  Enfora provides a separate product SKU for the Enabler EDG0208 module with the integrated SIM carrier.  6.8.2   Using a Remote SIM with the Enfora Enabler EDG0208 Module  The Enabler EDG0208 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 EDG0208 to the remote SIM connector must not exceed 25.4 cm (10 inches).

Integration Guide  Draft EDG0208IG001  Page 38  Rev. 1.03 –4/19/07  7.0  Modes of Operation  GSM/GPRS/EGPRS supports many optional services and modes.  The Enfora Enabler EDG0208 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 EDG0208 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 - EDG0208AT001 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 EDG0208 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 EDG0208 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 EDG0208 module can be configured to switch automatically to Non-Transparent mode.  This capability depends on the settings in the AT+CBST command.
Integration Guide  Draft EDG0208IG001  Page 39  Rev. 1.03 –4/19/07 7.4 SMS: Short Message Services    Short Message Services (SMS) is a feature-rich GSM service.  The Enfora Enabler EDG0208 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 EDG0208 Module  The following list details the key characteristics and assumptions regarding the form of SMS supported in the Enfora Enabler EDG0208 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   Replace SMS
Integration Guide  Draft EDG0208IG001  Page 40  Rev. 1.03 –4/19/07 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 EDG0208 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 EDG0208 Module  The Enfora Enabler EDG0208 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 EDG0208 Module  The Enfora Enabler EDG0208 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 EDG0208 Module  The Enfora Enabler EDG0208 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;    Quality of Service Options;

Integration Guide  Draft EDG0208IG001  Page 42  Rev. 1.03 –4/19/07  9.0 Software Interface  9.1 Software Interface  The application sends commands to the Enfora Enabler EDG0208 module via the I/O signal connector. These commands use the Enfora AT Command Set.  The Enfora Enabler EDG0208 module operates in one of the following modes:    Command mode: Used for configuring the Enfora Enabler EDG0208 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 EDG0208 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 EDG0208 module in Command mode but does not terminate the circuit-switched data call.)  The AT command driver of the Enfora Enabler EDG0208 module never exits the Command state, that is, it never enters the “On-line” mode.      In the Command state, characters that are received from the Customer Premise Equipment (CPE) are treated as AT commands by the Enfora Enabler EDG0208 module.    In response to the commands received from the CPE, the Enfora Enabler EDG0208 module sends characters (AT commands) to the CPE.    Various events can also trigger the Enfora Enabler EDG0208 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 - EDG0208AT001.    9.3 Enfora AT Command Set  For a full description of the AT commands, refer to the Enfora Enabler-IIE AT Command Set Reference - EDG0208AT001.  Note: A command description that includes an asterisk (*) denotes that the GSM service provider must enable supplementary services functionality before the command is available.
Integration Guide  Draft EDG0208IG001  Page 43  Rev. 1.03 –4/19/07 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 the power supply, connect the antenna, and install the SIM into the modem.  10.1.1  HyperTerminal Configuration for Enabler EDG0208  The following provides an example for setting up a Windows HyperTerminal session that can be used to experiment with various configurations on the Enabler EDG0208 for controlling computer:  1. Select the connection interface, Direct to Com 1 (or whatever port is the serial port).   Figure 20 HyperTerminal Definition
Integration Guide  Draft EDG0208IG001  Page 44  Rev. 1.03 –4/19/07  2. Configure the COM port as displayed below.  Figure 21 COM Port Settings  10.1.2  Initialization (AT Command Interface)  In the GSM vocabulary, a call from GSM mobile to the PSTN (Public Switched Telephone Network) 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 EDG0208 module is designated as:  Entry    The data exchange from the Enfora Enabler EDG0208 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  Draft EDG0208IG001  Page 45  Rev. 1.03 –4/19/07 10.1.3  Initial Response to the AT Command  After power is applied to the Enfora Enabler EDG0208 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 EDG0208 module responds with one of the following result codes:    “OK” signifies that the Enfora Enabler EDG0208 module is ready, that it correctly interprets the AT command, and that it has executed the command.    “ERROR” signifies that the Enfora Enabler EDG0208 module does not understand the command or that the command is invalid.  Entry  AT  Response  OK  Command valid: module is ready  The Enfora Enabler EDG0208 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 EDG0208 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.

Integration Guide  Draft EDG0208IG001  Page 47  Rev. 1.03 –4/19/07 11.0 Integration and Testing  The Enfora Enabler EDG0208 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 EDG0208 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  11.1  Integrating the Enfora Enabler EDG0208 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 EDG0208 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  RecommendationsSIM  The maximum line length of the SIM interface is 25.4 cm (10 inches). The Enfora Enabler EDG0208 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 EDG0208 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 EDG0208 module when tied low.
