This includes the lowest possible EMI emissions, maximum thermal conduction, mechanical integrity, and voice quality. The Enabler III LPP 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. Warning: 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.
Enfora Enabler III LPP Integration Guide Page 10 Revision: 0.00 3.5.1 ADVANCED TIPS FOR AN RF FRIENDLY LAYOUT 3.5.1.1 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 to create a low impedance ground. It is recommended to minimize the number of I/O and power traces under the GSM module to allow for as much ground plane as possible. An example of a good ground structure and pad layout is shown below in Figure 1 - Example of good ground plane for GSM modules. Figure 1 - Example of good ground plane for GSM modules
Enfora Enabler III LPP Integration Guide Page 11 Revision: 0.00 3.5.1.2 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. However, 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. POOR RF thermal
Enfora Enabler III LPP Integration Guide Page 12 Revision: 0.00 Figure 3 - Example of a GOOD RF Thermal Relief 3.5.1.3 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. GOOD RF thermal
Enfora Enabler III LPP Integration Guide Page 13 Revision: 0.00 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 as possible. 3.5.1.4 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. 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. 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. The layout should provide sufficient trace width over the entire trace from the Enabler module all the way to the source of the Vbat voltage. Any transitions between layers for this trace should utilize multiple vias. Figure 4 - Example of Vbat Voltage Droop Two 470 uF, low ESR, tantalum capacitors are included in the design to provide decoupling of Vbat input voltage. Bulk decoupling capacitance is not required at the Vbat input external to the Enabler module.

Enfora Enabler III LPP Integration Guide Page 22 Revision: 0.00 5.3 CIRCUIT PROTECTION Other than very low level ESD protection within the module’s integrated circuits, the module does not have any protection against ESD events or other excursions that exceed the specified operating parameters. 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 47Ω) can also be added in series with data lines to limit the peak current during a voltage excursion. Warning: Do not add series resistance to the SIM electrical.

Enfora Enabler III LPP Integration Guide Page 23 Revision: 0.00 5.4 CONTROL CONNECTOR SIGNAL DESCRIPTIONS AND FUNCTIONS Note: The following descriptions are intended to provide hardware-level definitions. In some cases, specific lines will have no firmware functionality implemented. Information for each hardware-specific feature will be noted in the appropriate section. 5.4.1 MODULE POWER (PINS 30, 31) The Enfora Enabler III LPP module uses a single voltage source of VCC=+3.3V to 4.5V. (The exact values of the uplink currents are shown in the tables in section 5.3.1.) VBAT Parameter/Conditions Min Typ Max Units Main Battery Supply Voltage In Regulation 3.3 4.5 Vdc Warning: The uplink burst will cause strong ripple on the voltage lines and should be effectively filtered. External capacitance is not typically required by low current or extended life applications. However, if capacitance is added, then current leakage of the capacitor needs to be taken into consideration for these types of applications. 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.
Enfora Enabler III LPP Integration Guide Page 24 Revision: 0.00 5.4.2 ON/OFF SIGNAL (PIN 4) The module may be set into a low power ‘off’ mode by pulling the pin low for a minimum of 3 seconds. This will shut down any active functions including GPS and GSM, and stop the MSP430 processor. This is the lowest power mode of the module, it can be ideally used when storing or shipping units and the controller is not to be enabled. Once the module is in the ‘off’ state, it can be turned ‘on’ by holding the pin low for a minimum of 3 seconds. This will start the MSP430 processor, once booted the controller will be enabled and run as per the saved settings. The module will normally start in the ‘on’ state and enable the controller logic when power is applied. 5.4.3 ON/OFF STATUS (PIN 5) When the On/Off pin is used to put the module into an ‘off’ state or to turn it ‘on’, the status pin will indicate when it has successfully entered either state. When turning off the unit, the status signal is set high after the On/Off signal is sufficiently held low (3 seconds). The status signal is held high for 3 seconds but can stay enabled if the system is waiting for the modem to shut down. When turning on the unit, the on/off status signal will blink 12 times within a 3 second period if the battery voltage is in its highest range. If the battery is within its normal voltage range, the on/off status signal will blink on for one second, off for one second, then on for one second. The on/off status signal will then go off. When the signal is off, the unit is activated. 5.4.4 GENERAL PURPOSE INPUT SIGNALS (PINS 10, 11) Two signals are available for input signals which can be controlled via user configuration of the modem software. The voltage level of the signal must be in reference to the selected VIO voltage (Pin 33). 5.4.5 GENERAL PURPOSE OUTPUT SIGNALS (PINS 12, 13) Two signals are available for output signals which can be controlled via user configuration of the modem software. Commands are provided to change the state of the output signals. The voltage level of the signal must be in reference to the selected VIO voltage (Pin 33). 5.4.6 RESET SIGNAL (PIN 24) The Reset signal is used to force the micro-controller to start at a known state. When the Reset is pulled low the micro-controller will immediately suspend any function and will not exit the reset state until the reset signal is released to be pulled
Enfora Enabler III LPP Integration Guide Page 25 Revision: 0.00 high. Once the transition from low to high is complete, the micro-controller 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 lose the connection to the GSM network, this is not considered ideal. Typically during a normal shutdown, the module will issue a detach request to the network to indicate that it is being removed.

Enfora Enabler III LPP Integration Guide Page 29 Revision: 0.00 5.5 SUBSCRIBER IDENTITY MODULE (SIM) (PINS 42, 43, 44, 45, 46) 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 MSP430 processor and memory installed on a plastic card. Note: The SIM is not provided with the Enfora Enabler III LPP 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. 5.5.1 USING A REMOTE SIM WITH THE ENFORA ENABLER III LPP MODULE (PINS 42, 43, 44, 45, 46) The Enabler III LPP module does not include an on-board SIM carrier. The module supports the use of 1.8 V and 3 V SIM cards. The module includes a hardware interface module dedicated to Universal Subscriber Identity Module (USIM). All baud-rates defined in ISO 7816-3 standard are supported for high-speed transmission. • 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  kV Contact Discharge
Enfora Enabler III LPP Integration Guide Page 30 Revision: 0.00 The transorb must have a low junction capacitance (typically < 10 pf) such as the following part: Example: Manufacturer: On Semi Manufacturer PN: NSQA6V8AW5T2G Figure 7 - Remote SIM Interface Pin Name Pin Number Signal Direction Description SIM_VDD 45 O SIM VDD SIM_CLK 43 O Card Reference Clock SIM_RST 42 O Card Reset SIM_I/O 44 I/O Card I/O Data SIMDTC 46 I Card Detect The module provides the regulated supply voltage for the SIM-card and the circuitry to detect the insertion or extraction of the SIM-Card in or from the mobile. The SIMDTC is disabled by default (see AT$SIMDTC in the AT Command Manual for settings). When enabled, the SIMDTC pin has an internal pull up to Vcc and can
Enfora Enabler III LPP Integration Guide Page 31 Revision: 0.00 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. The SIM-card presence detection logic is active when the GSM modem is on and is checked each time the GSM modem is powered up.

Enfora Enabler III LPP Integration Guide Page 32 Revision: 0.00 5.6 ANTENNA The LPP0208 module has two RF antenna connections. One connection is for the GSM section of the module and the other for GPS. Please be sure to follow proper RF design practices when designing the antennas. 5.6.1 GSM A GSM antenna should be designed from proper RF design practices. 5.6.2 GPS The GPS_ANT is the RF connection from the GPS antenna; no external LNA is required. The LPP0208 can support both passive and active GPS antenna. However, external power supply and circuitry is required for an active GPS antenna. See Figure 12 - GPS Antenna Sample Schematic Figure 8 - GPS Antenna Sample Schematic Active antenna is enabled by placing a jumper on J403 in the sample schematic between pins 1 and 2. Passive antenna is enabled by placing a jumper on J403 in the sample schematic between pins 2 and 3.

Enfora Enabler III LPP Integration Guide Page 34 Revision: 0.00 7 GSM/GPRS Modes of Operation GSM/GPRS supports many optional services and modes. The Enfora Enabler III LPP 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 III LPP module has voice capabilities, provided the necessary connections have been made for the speaker and microphone pins. The Enfora Enabler-LPP G AT Command Set Reference – LPP0208AT001 has the entire list of commands that can be used to control the voice functionality. The Enfora Enabler III LPP module supports four vocoder compression algorithms for voice communication: Full-Rate (FR), Enhanced Full-Rate (EFR), Half-rate (HR) and Adaptive Multi-rate (AMR).
Enfora Enabler III LPP Integration Guide Page 35 Revision: 0.00 7.3 SMS: SHORT MESSAGE SERVICES Short Message Services (SMS) is a feature-rich GSM service. The Enfora Enabler III LPP 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 SIM OPERATION 7.4.1 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) • The GSM SIM can have multiple telephone numbers. It is imperative for the Enfora Enabler III LPP module that the SIM be configured for the optional services that are required for the application.
Enfora Enabler III LPP Integration Guide Page 36 Revision: 0.00 7.5 GPRS SERVICES SUPPORTED BY THE ENFORA ENABLER III LPP MODULE The Enfora Enabler III LPP 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 • Up to Multi-slot 10 Class of Service 7.6 SELECTING THE GSM MODES OF OPERATION When provisioning the SIM for the Enfora Enabler III LPP 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 MO/MT MO/MT Voice calls, receive / send SMS MO/MT MO/MT Voice calls, receive / send SMS 7.7 POWER MANAGEMENT TBD
Enfora Enabler III LPP Integration Guide Page 37 Revision: 0.00 8 Software Interface The application sends commands to the Enfora Enabler III LPP module via the 52-pin I/O signal connector. These commands use the Enabler III LPP Menu System, Enfora AT Command Set and/or Enfora GSM-GPRS Family API. The Enfora Enabler III LPP module operates in one of the following modes: • Command Menu mode: Used for configuring the Enfora Enabler III LPP module. It uses menu based commands via the serial port for communication. See LPP0208PR001 - Enfora Enabler III LPP Programming Reference for more details on specific commands. • Modem Pass-Thru mode: Used to communicate directly with the modem. It uses the AT command set via the serial port for communication. Entry to this mode is available via a menu mode command. • AT Command via USB: The USB port may be used to send AT commands directly to the GSM modem. This method should be used for configuration purposes, not normal usage. The GSM modem remains powered on as long as the USB port is connected. 8.1 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-LPP G AT Command Set Reference - LPP0208AT001.
