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 LPP G product to open flames. Ensure that liquids do not spill onto the devices.
ERP and EIRP measurements for FCC Parts 22 and 24, alternatively a full retest on FCC Parts 22 and 24 can be performed. 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.
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. 2.2.

4.5.1.Advanced tips for an RF friendly layout 4.5.1.1. 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.
4.5.1.2. 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.
GOOD RF thermal relief Figure 3 - Example of a GOOD RF Thermal Relief 4.5.1.3. 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.
4.5.1.4. 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.
4.5.2.Audio Reference Design The audio quality is very dependent on the circuit design and layout. As an aid to obtaining good audio quality, a reference design has been included below. It has been proven to provide good performance on the SDK module. 4.5.2.1. Audio Schematics Figure 5 - Audio Reference Design Schematic 4.5.2.2.

6.2. I/O Pin Assignments The following table shows the pin assignments for the input/output connector.
I = Input into Module O = Output from Module P = Power Input to Module R = Power Return from Module I/O = Input/Output to/from Module PWR = Other Power 6.3. 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.
6.4. Power Button and Status LED The power button is polled once per second. Once the power button press is detected, the signal is debounced using Timer A. The button must be held for three (3) seconds to deactivate the device. Once sufficient button press and hold occurs, the status LED is enabled for three (3) seconds. If the modem is on at the time of deactivation, the status LED on-time is extended until the modem turns off. Next the system enters LPM4 mode and the unit is deactivated.
Passive antenna is enabled by placing a jumper on J403 in the sample schematic between pins 2 and 3.
6.6. Control Connector Signal Descriptions and Functions Please note that 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. 6.6.1.Module Power (Pins 30, 31) The Enfora Enabler LPP G module uses a single voltage source of VCC=+3.3V to 4.5V.
6.6.2. 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 shutdown any active functions including GPS and GSM, and stop the 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.

6.6.4.Serial Interfaces 6.6.4.1. Main Serial Interface (Pins 17, 18) The pin naming for TX/RX is referenced as a DTE. The DTE device should match their input pins to the Enfora outputs and vice-versa.
6.6.4.2. GPS Serial Interface (Pin 19) It is optional as to whether something should be connected to the RS232 GPS DEBUG OUT. If streaming NMEA messages are needed for external processing, above and beyond the NMEA sent to the server, then a serial cable can be connected between this serial connector and a PC. The baud rate is fixed at 19200.
6.6.5.Handset Microphone Input (Pins 39, 40) The handset differential inputs MICIP and MICIN can be amplified by the differential handset microphone amplifier. This amplifier has a gain of 25.6 dB.

6.7.1. Using a Remote SIM with the Enfora Enabler LPP G Module (Pins 42, 43, 44, 45, 46) The Enabler LPP G 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.

7. Battery Charging Calibration and Configuration 7.1. Objective The objective of this document is to outline how to configure the Enabler LPP G based battery charger for specific batteries and chargers. 7.2. Supported Devices Enabler LPP G 7.3. References LPM0108AT001- Enabler LPP G AT Command Set 7.4. List of battery charging commands The following is a list of Locosto/Triton-Lite battery charger AT commands, and who is responsible for setting their parameters.
7.4.1.Setting BCIVSF parameters BCIVSF sets the scaling factor so the battery voltage reported by the Triton-Lite matches the real battery voltage on the Vbat pin. This one-time calibration should be done at module production. 7.4.2. Equipment required Programmable power supply with <10mV resolution and voltage sense lines. A notebook or desktop computer with any version of Microsoft Windows that has the HyperTerminal communications program.
7.4.4.Setting BCIISF Parameters The charging current calibration requires measuring the current at 2 levels and determining the adc_num and adc_offset based on the physical currents (Iphy) and reported charging currents (Ichg_avg_mA). Two points are required to get accurate calibrations at both the high and low current levels. 7.4.5. Scope This calibration does not need to be done as part of a factory level production test on every device, default values can be used to get ballpark readings.

7.5. Setting BCIAVG parameters Averaging of the voltage, temperature, and current readings is used to reduce noise or spikes that could otherwise trigger ill-timed state changes or inaccurate readings. It is up to the user’s comfort level what values should be set. Setting any alfa=0 my give readings that are too noisy, especially in the case of current readings. Setting alfa to a very large number will cause state transitions to occur later than desired while the averaging “catches-up”. 7.6.
7.6.4.Set the desired CI charge current for the designated charger. Determining the charge current for the constant-current charging stage now will make the BCIMAP# <%> parameters more accurate. Typical limiting values are listed in the following table: Charger USB charger Wall charger Triton-Lite Customer charger Max. charge current 500mA Limited by Triton-Lite maximum 800mA X [0-255] 160 255 255 Calculate1 Note: = [ 0.22 * (CI + ISYS) * 10 + 0 ] * 255 / 1750. Max value is 255.
