Enfora Enabler IIIG BGA Modem Integration Guide 1. 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 IIIG BGA product to open flames. • Ensure that liquids do not spill onto the device. • Do not attempt to disassemble the product: Doing so will void the warranty. This product does not contain consumer-serviceable components. 2. Regulatory Compliance FCC 2.1. Integration Considerations and Installation Requirements The Enabler IIIG BGA 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. • Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. In order to use the Enabler IIIG BGA modem 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 7.0 dBi. • If used in a "portable" application such as a handheld or body worn 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 and the device will require its own FCC ID: i. 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). ii. 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). iii. ERP and EIRP measurements for FCC Parts 22 and 24, alternatively a full retest on FCC Parts 22 and 24 can be performed GSM0408IG001 Page 1 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide • 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: MIVGSM0408 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: MIVGSM0408 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. GSM0408IG001 Page 2 Rev. DRAFT – 03/10/2008

Layout Guidelines for the Enabler IIIG BGA The following guidelines are provided in an effort to allow Enabler IIIG BGA 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 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. 4.6.1. Placement When integrating the Enabler IIIG BGA into a host design, it is critical for the design engineer and system architect to take steps early on in the design to minimize the potential noise and interference issues associated with proximity of RF sources, clock sources and receivers. Carefully determining the optimum placement for the module will ensure the best performance for GSM communication. All potential sources of noise and interference should be taken into consideration before determining where each module and circuit should be physically placed in the design. A system frequency plan is recommended in order to avoid system clock frequencies with harmonics at 13MHz, 26MHz, or the GSM 850/900/1800/1900 operational bands. Please refer to Figure 1. The module should be rotated and placed such that the RF antenna trace is as short as possible. Refer to section 4.6.4 for more detail on RF routing. Bulk bypass capacitance should be placed adjacent to the power input pads as shown, and power traces should be 0.1” (2.54mm) wide as a minimum, or wider if routing is longer than 5” (127mm). Refer to section 4.6.5 for detailed discussion of power input. GSM0408IG001 Page 13 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide Figure 1 – Example of placement and ground plane for the module host board 4.6.2. Ground Plane To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is imperative that all ground balls on the Enabler IIIG BGA module be soldered to a continuous ground plane. This ground plane should cover a minimum of the RF/power quadrant of the module, as shown in the upper left area of Figure 1, and should be interconnected to ground flooding on other layers so that there are no ground loops between module pads. Ground vias should be provided under or adjacent to each ground pad to create a low impedance ground. It is recommended to minimize the number of top-layer I/O traces under the module to allow for as much ground plane as possible. An example of a good ground structure and pad layout is shown in Figure 1, and solid grounding through via interconnect in Figure 2. Figure 2 – Example of solid flooding on layer 4 with via interconnect GSM0408IG001 Page 14 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 4.6.3. Thermal Relief Because the ground plane acts as a large heat sink, it can affect the solder adhesion of the module. 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. Insufficient grounding caused by narrow elongated thermals will result in poor thermal transfer, constricted ground current return, and inadequate RF grounding. Poor RF grounding may be manifested by excessive radiated or conducted harmonics. Figure 3 shows an example of host board grounding in the RF/power area of the module. Recommended design parameters are 10 mils (.254 mm) copper flood clearance and 15 mils (.381 mm) thermal spoke width. A grounding via should be located either directly adjacent to the pad if using thru-hole vias or can optionally be located in the pad for blind via design. For blind via technology with via-in-pad, the vias must be filled and plated over to remove the dimple. See section ??? for process specifications with regard to module attachment to the host. Figure 3 – Example of thermal relief and Vbat feed 4.6.4. Antenna and RF Signal Trace The PCB trace that feeds the RF output port must be designed for a 50 ohm characteristic impedance. It should be 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 trace and launch pad. Special care should be taken when the RF trace changes layers between the module and the antenna port or connector, as such transitions can introduce an additional mismatch and degrade system sensitivity. If possible, keep I/O and power traces away from the RF port. This includes traces running parallel or orthogonal to it. The designer must pay close attention to the 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 be 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 GSM0408IG001 Page 15 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 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. 4.6.5. 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 routing connections to the Enabler Vbat pads, it would seem reasonable to use traces of the same width as the pads. However, such traces will not have sufficient copper. The use of narrow traces to connect the Vbat pads 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 Vbat drops too low, the Enabler module will reset. To minimize the trace loss, it is recommended to use a larger trace that spans several pads as shown in Figure 3. The layout should provide sufficient trace width over the entire route from the module 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 module. It is suggested to use at least two 1000 uF low ESR tantalum capacitors located adjacent to the module Vbat pads. Any thermal relief used on these capacitors should comply with the information given above in order to provide the lowest impedance possible. The design should include multiple vias to the internal ground plane, placed close to the capacitors, as grounding of these capacitors is critical. 4.6.6. I/O Routing and Fanout The Enabler IIIG BGA interface is grouped by functions, as shown in the BGA map of section 5.5.1. Each functional group should be fanned out and routed as a group from the module. It is preferred to route as much of the I/O nets as possible on internal layers in order to maintain continuous grounding. Pad spacing on the module allows for flexibility in placing vias adjacent to the pads. Figure 5 and Figure 6 are both examples of functional grouping and fanout. Note that GSM0408IG001 Page 16 Rev.

VBAT Parameter/Conditions Min Typ Max Units Main Battery Supply Voltage In Regulation 3.3 4.5 Vdc Peak Current 1000 μF on Host at module interface TBD mA The uplink burst will cause strong ripple on the voltage lines and should be effectively filtered. It is recommended that 1000 to 2000 F of capacitance be placed as close to the modem power input pads 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. GSM0408IG001 Page 32 Rev.

Enfora Enabler IIIG BGA Modem Integration Guide 5.7.2. Antenna (Pad A1) The module has one RF antenna pad on the module. The connection is for the GSM section of the module. 5.7.3. Reset Signal (Pad F6, also known as ON_\OFF) 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, which 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 should be used during network operations only when there is no response from the module. Controlling the Reset signal must only be preformed 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.

Enfora Enabler IIIG BGA Modem Integration Guide 5.7.4. Power Control (Pad K9) (PWR_CTL) The input is equivalent to a “phone ON-button”. A falling-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. See section 6.6.9 for more info on the RTC. 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). *The OFF Delay is controlled by the AT$OFFDLY command. A value of 0 disables the PWR_CTL line from turning the module off. 0 is the default value. To enable the module to switch-OFF via PWR_CTL you must set AT$OFFDLY to a value other than 0. The valid range is 100 to 1000 milliseconds. Turning ON the Enabler IIIG BGA Pulling the PWR_CTL line on the module LOW for at least 50mS (after Vbat is applied and stabilized) is required to turn it ON. Section 0 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. Turning OFF the Enabler IIIG BGA The module can be turned off by either a low pulse on the PWR_CTL line, or by a software command (AT$OFF, see AT guide for further details). Section 0 describes various ways to provide the signal. GSM0408IG001 Page 34 Rev. DRAFT – 03/10/2008

The RTC deep sleep functions will NOT function since the PWR_CTL pad is tied low, the processor will never stay in a “RTC Sleep” mode. Either the RESET pad must be toggled (as described in section 5.7.3), or power (VBAT) must be cycled to reset the module. GSM0408IG001 Page 35 Rev. DRAFT – 03/10/2008

Enfora Enabler IIIG BGA Modem Integration Guide 5.7.9. Serial Interface The pad naming for TX/RX/RTS/CTS/DTR/DSR is referenced as a DCE .The DTE device should match their input pads to the Enfora outputs and visa-versa. Additionally, there are AT commands that may need to be executed in order to ensure proper operation. See the chart below. NOTE: The UART interface on the Enabler IIIG BGA, as well as other I/O, is 1.8V logic. It should not be directly connected to a higher voltage interface. The table below is a reference of D connector pin numbers only. 9 way D Connector Pin Number Signal Signal Direction Enfora Pad Number Enfora AT Command 1 Carrier Detect (CD) from DCE C11 AT&C 2 Receive Data (RD) from DCE B11 3 Transmit Data (TD) from DTE D11 4 Data Terminal Ready (DTR) from DTE B12 AT&D 5 Signal Ground both 6 Data Set Ready (DSR) from DCE D12 7 Request To Send (RTS) from DTE C13 AT+IFC 8 Clear To Send (CTS) from DCE C12 AT+IFC 9 Ring Indicator (RI) from DCE C10 The key features of the UART in the modem mode are as follows: • 16C750 compatibility • Baud rate from 300 bits/s up to 921600 Kbits/s, autobaud • Configurable data format: • Data bit: 5, 6, 7, or 8 bits • Parity bit: even, odd, none • Stop bit: 1, 1.5, 2 bit(s) • Hardware flow control RTS/CTS • Software flow control using XON/XOFF characters Default settings are 8 data, 1 stop, no parity, and autobaud. 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 (asserted low) 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 (through level translation if the interface is not 1.8V). Connect DTR and RTS on the host side of the interface to GND, while leaving the corresponding lines on the module floating. Ring Indicate (Pad C10) The module is capable of using the Ring line to discern the type of incoming call. 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 GSM0408IG001 Page 40 Rev. DRAFT – 03/10/2008

This pad is used to automatically switch to the headset audio path when enabled with AT$VSELECT=3. The device will default to handset when no Headset is detected. • 2 modes:  Module already ON (Battery connected, VRIO ON) and plug event;  Module OFF and plug event: the plug detection will be effective once VRIO is set ON • Plug and unplug detections are digitally debounced (debouncing time = 8 ms). • The jack plug detection feature is addressed through the HSDET pad. The integrated pull up, connected to the pad, forces a high level (VBAT) when the headset load is not connected. At jack insertion headset load connection (32 Ω) imposes a low level on that node (Headset left channel): as an example HSDET = 1 mV after jack plug for VBAT = 4 V. = VBAT/2 – 100 mV and VT• Input comparator threshold voltages are defined as VTlow high = VBAT/2 + 100 mV, VBATmin = 3.2 V. The plug and unplug detection remains functional if there is no signal from HSOL amplifier output (stereo path is OFF) or if there is a signal from HSOL (stereo path is ON): maximum level on HSOL when the stereo path is ON is 1 Vp-p which stays far enough from the comparator threshold levels VBATmin/2 – 100 mV and VBATmin/2 + 100 mV. • Jack plug detection is functional if a plug event occurs before the power up of the module or if the plug event occurs after the power up of the module: analog detection part is always active if the battery is connected. Detection interrupts will be generated once the VRIO regulator is power up during the module power up sequence. • A level change on HSDET pad is sensed by a Schmitt trigger to provide a jack detection signal to the audio digital control. The audio digital control receives the detection signal and proceeds to a digital debouncing (time: 8 ms = 256 * 32 kHz clock periods) before sensing that a plug event happened on the jack connector.

Remote Subscriber Identity Module (SIM) (Pads A7, A9, B7, B8, H5) 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 Enabler IIIG BGA module does not include an on-board SIM carrier, nor is a SIM provided with the 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 module will not operate properly without an attached SIM. GSM0408IG001 Page 47 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 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. The module supports the use of 1.8 V and 3 V SIM cards. All baud-rates defined in ISO 7816-3 standard are supported for high-speed transmission. As noted above, the Enabler IIIG BGA requires a remote SIM carrier/connector. When using a remote SIM, the following guidelines are provided: • To utilize a remote SIM, the integrator must provide a suitable SIM connector. • The maximum distance from the module to the remote SIM connector must not exceed 25.4 cm (10 inches). • It is recommended to have Zero resistance between the SIM connector and the module. • External ESD Protection is Required;  15 kV Air Discharge;  8 kV Contact Discharge; The transzorb must have a low junction capacitance (typically < 10 pf) such as the following part: Enfora PN: TRS-0000-5009 <25.4 cm (10 in)Manufacturer: On Semi Manufacturer PN: NSQA6V8AW5T2G Figure 19 - Remote SIM Interface SIM_CLKSIM_I/OSIM_RSTSIM_VDDEnabler IIIG module Remote SIM SIM Interface SIM_DTCGSM0408IG001 Page 48 Rev.

The SIMDTC is disabled by default (see AT$SIMDTC in the EIII AT Command Manual for settings). When enabled, the SIMDTC pad has an internal pull up to Vcc and can be configured to detect a SIM insertion when the SIMDTC is either pulled to ground or left floating. It can configured to detect either just a SIM removal or both removal and insertion. When the module detects a SIM removal, it will de-register from the network. When the module is configured to and detects a SIM insertion, it will reset the module and re-register on the network.

Enfora Enabler IIIG BGA Modem Integration Guide 6. GSM/GPRS Modes of Operation GSM/GPRS supports many optional services and modes. The Enfora Enabler IIIG BGA module supports the following GSM/GPRS services: • Circuit-switched data • Short-Message Services (SMS) • Class B GPRS Functionality • Voice communication 6.1. 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. 6.2. Voice Communication The Enfora Enabler IIIG BGA module has full voice capabilities, provided the necessary connections have been made for the speaker and microphone pads. The Enfora Enabler-IIIG AT Command Set Reference - GSM0308AT001 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 module supports four vocoder compression algorithms for voice communication: Full-Rate (FR), Enhanced Full-Rate (EFR), Half-rate (HR) and Adaptive Multi-rate (AMR). 6.3. Circuit-Switched Data In this mode, the 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 module can be configured to switch automatically to Non-Transparent mode. This capability depends on the settings in the AT+CBST command. GSM0408IG001 Page 50 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 6.4. SMS: Short Message Services Short Message Services (SMS) is a feature-rich GSM service. The Enabler IIIG BGA 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) GSM0408IG001 Page 51 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 7. SIM Operation 7.1. 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 Enabler IIIG BGA module that the SIM be configured for the optional services that are required for the application. 7.2. GSM Services Supported by the Enabler IIIG BGA Module The 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. 7.3. GPRS Services Supported by the Enabler IIIG BGA Module The 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 7.4. Selecting the GSM Modes of Operation When provisioning the SIM for the 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) • Circuit Switched Data: configure the SIM either for MO alone (to send) or for both MO and MT (to send and receive) GSM0408IG001 Page 52 Rev.

Enfora Enabler IIIG BGA Modem Integration Guide 8. Software Interface 8.1. Software Interface The application sends commands to the module via the UART interface pads. These commands use the Enfora AT Command Set and/or Enfora’s Packet API. The Enabler IIIG BGA module operates in one of the following modes: • Command mode: Used for configuring the 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 Enabler IIIG BGA 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 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 API Reference GSM0308UG001. The AT command driver of the 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 module. • In response to the commands received from the CPE, the module sends characters (AT commands) to the CPE. • Various events can also trigger the module to send characters (AT commands) to the CPE. Format for the AT Commands The general format of the command line is: <prefix> <command> <CR> AT <prefix> See AT Command Manual <command> 0X0D <CR> 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-IIIG AT Command Set Reference – GSM0308AT001. GSM0408IG001 Page 54 Rev. DRAFT – 03/10/2008

Enfora Enabler IIIG BGA Modem Integration Guide 2. Configure the COM port as displayed below. Figure 21 - COM Port Settings 8.4.3. 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 module is designated as: Entry The data exchange from the 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. GSM0408IG001 Page 56 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 8.4.4. Initial Response to the AT Command After power is applied to the module, the module performs a power-up self-test. The self-test completes within one (1) second. When queried with the AT command, the module responds with one of the following result codes: • OK signifies that the module is ready, that it correctly interprets the AT command, and that it has executed the command. • ERROR signifies that the module does not understand the command or that the command is invalid. AT Entry OK Response Command valid: module is ready The module must be in AT Command mode (please refer to section 8.6 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. 8.4.5. Sending an Initialization String to the Enabler IIIG BGA 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 AT&FE0Q0V1&C1&d0Entry Initialization string OK Response Command is valid ATSO=1 Entry Auto answer on 1st ring OK Response Command is valid GSM0408IG001 Page 57 Rev.

Enfora Enabler IIIG BGA Modem Integration Guide 9. Integration and Testing The Enabler IIIG BGA 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 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 9.1. Integrating the Enfora Enabler IIIG BGA 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 module. All of these conditions need to be verified at ambient as well as extreme conditions. GSM0408IG001 Page 60 Rev. DRAFT – 03/10/2008
Enfora Enabler IIIG BGA Modem Integration Guide 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 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 IIIG BGA module uses a 1.8V digital interface. The RS-232 signals must be level-shifted to get standard levels. These signals must be ESD-protected. Reset Interface Resets the module when tied low. The signal must be driven from an open collector/drain source. Audio/Microphone Interface Preliminary balancing on the module.

Note: Additional care must be taken by the installer and/or user of the Enfora Enabler IIIG BGA module to ensure proper antenna selection and installation. Adherence to the above conditions is necessary to comply with FCC requirements for safe operation regarding exposure to RF radiation. Depending upon the application and type of product into which the Enfora Enabler IIIG BGA module has been incorporated, specific OEM actions and responsibilities required to meet these conditions vary. However, in all cases the primary concern is to ensure compliance with current FCC guidelines and regulations that limit human exposure to radio frequency radiation. Definitions For the purpose of determining compliance with current FCC rules addressing human exposure to radio frequency radiation, the FCC has established the following three categories of transmitting devices: • Portable Devices – devices where the antenna is located within 20 cm (7.87 inches) of any person, including the user, if applicable. Portable devices operating under the authority of Part 22 or 24 (broadband PCS) are limited to a maximum of 2 W EIRP. • Mobile Devices – devices designed to be used in other than fixed locations and generally such that the antenna is located at a minimum of 20 cm (7.87 inches) from any person, including the user, if applicable. Mobile devices operating under the authority of Part 22 or 24 (broadband PCS) are limited to a maximum of 2 W EIRP. • Fixed devices – devices in which the antenna, either integral to the product or remotely located, is physically secured at one location and is not able to be easily moved to another location. The antenna for a fixed device is mounted on an outdoor permanent structure with a minimum separation distance of 2 meters (79 inches) 11.8.1.
