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.

 Do not attempt to disassemble the product: Doing so will void the warranty. With the

exception of the Subscriber Identification Module (SIM), this product does not contain

consumer-serviceable components.

2. Regulatory Compliance FCC

2.1. Integration Considerations and Installation Requirements

The Enabler LPP G module 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 Enabler LPP G module 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 LPP G module without additional FCC certification approvals, the

installation must meet the following conditions:

Maximum RF output power and antenna gain to meet Maximum Permissible Exposure

Requirements: GSM850 mode: Power at antenna port is +33 dBm. The maximum gain

is 1.4 dBi. GSM1900 mode: Power at antenna port is 30 dBm. The maximum gain is 7

dBi in order to meet the requirements of maximum 2 watts EIRP for mobile transmitters. If

RF power and/or antenna gain is desired, a separate FCC certification is required.

 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:

 SAR (Specific Absorption Rate) testing, with results submitted to the FCC for

approval prior to selling the integrated unit. If unable to meet SAR requirements,

then the host unit must be restricted to "mobile" use (see below).

 Unintentional emissions, FCC Part 15; results do not have to be submitted to the

FCC unless requested, although the test provides substantiation for required labeling

(see below).

LPP0108IG001 2 Version - Preliminary – 06/20/08

 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

(7.9 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 Enabler LPP G module 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 module.

For example, the label should contain wording such as:

Contains GSM/GPRS modem transmitter module

FCC ID: MIVLPP0108

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.

Contains FCC ID: MIVLPP0108

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 Enabler LPP G module 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.

LPP0108IG001 3 Version - Preliminary – 06/20/08

 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. Disclaimer

The information and instructions contained within this publication comply with all FCC, GCF,

PTCRB, R&TTE, IMEI and other applicable codes that are in effect at the time of publication.

4.5. General design guidelines for utilizing Enfora GSM modules

The following guidelines are provided in an effort to allow Enabler LPP G 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 LPP G 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.

LPP0108IG001 13 Version - Preliminary – 06/20/08

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.

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

LPP0108IG001 14 Version - Preliminary – 06/20/08

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. 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 relief

LPP0108IG001 15 Version - Preliminary – 06/20/08

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. 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 as possible.

GOOD RF thermal relief

LPP0108IG001 16 Version - Preliminary – 06/20/08

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.

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.

LPP0108IG001 17 Version - Preliminary – 06/20/08

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

4.5.2.2. Audio Layout

Layout plots for the audio section of the SDK are available upon request.

4.6. Handling and Soldering Guidelines

The guidelines presented in IPC/JEDEC J-STD-020C for handling, preparation, and reflow of

lead-free devices should be applied to the Enabler LPP G module. Care should be taken to

minimize module moisture exposure before reflow. The module is classified as a Type 3 MSL

(moisture sensitivity level).

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. 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.

NOTE: DO NOT ADD SERIES RESISTANCE TO THE SIM ELECTRICAL LINES.

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.

The MSP exits LPM4 mode when the button is pressed again. The button signal is debounced

again using Timer A. The button must be held for three (3) seconds to activate the device. If the

button is not held long enough, the system re-enters LPM4. Once sufficient button press and

hold occurs, the status LED blinks (four times per second) for three seconds. The system is now

activated.

6.5. Antenna

The LPP0108 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.

6.5.1. GSM

A GSM antenna should be designed from proper RF design practices.

6.5.2. GPS

The GPS_ANT is the RF connection from the GPS antenna; no external LNA is required. The

LPP0108 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

Active antenna is enabled by placing a jumper on J403 in the sample schematic between pins

1 and 2.

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.

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.

LPP0108IG001 30 Version - Preliminary – 06/20/08

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. This will start the 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.

6.6.3. On/Off Status (Pin 5)

When the On/Off pin is used to put the modem 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 normally 3 seconds but can stay enabled for up to 5-6

seconds if the system is waiting for the GSM modem to shut down.

When turning on the unit, the status line blinks for 3 seconds at a frequency of 4Hz.

6.6.1. General Purpose Input Signals (Pins 10, 11)

Two input pins are available for input and are configured in conjunction with the event engine of the GSM

modem. The voltage level of the signal must be in reference to the selected VIO voltage (Pin 33).

6.6.1. General Purpose Output Signals (Pins 12, 13)

Two input pins are available for output signals and are configured in conjunction with the event engine of

the GSM modem.

The voltage level of the signal must be in reference to the selected VIO voltage (Pin 33).

6.6.2. 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 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.

6.7. 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 microprocessor and memory installed on a plastic

card.

Note: The SIM is not provided with the Enfora Enabler LPP G 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.

LPP0108IG001 36 Version - Preliminary – 06/20/08

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.

 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 transorb must have a low junction capacitance (typically < 10 pf) such as the following part:

LPP0108IG001 37 Version - Preliminary – 06/20/08

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 EIII AT Command Manual for settings).

When enabled, the SIMDTC pin 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.

The SIM-card presence detection logic is active even when the system is in idle model.

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. If this hardware is not available, the user could use a

DOS terminal emulation program.

7.4.3. Procedure

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. Customer level calibration is required if the

battery charge current and end-of-charge current are critical.

7.4.6. 6.2 Equipment required

1. Battery simulator, or mostly discharged battery.

2. Power supply with capability to measure current, 5-12V, 1A, to emulate wall charger. Agilent

3. A notebook or desktop computer with any version of Microsoft Windows that has the HyperTerminal

3. The strategy for production level calibration is to set an arbitrary low and high charge currents

that will optimize accurate Ichg readings in most charging applications.

4. The strategy for customers in setting the low and high charging currents is to calibrate at the two

most important points in the charge process, <ci_chgireg> and <IEOC>, thus ensuring the state

transitions are accurate. <ci_chgireg> and <IEOC> are determined once as a system-level design.

<ci_chgireg> = [0 to 255] such that the Ichg = Isys + 1*C (800mA max.). <IEOC> =Isys + C/20. For

example, if the battery capacity is 1980mAh and the system current is 50mA, Ichg = 50+1980 =

2030mA => 800mA. <chgireg1>=255. <IEOC> =Isys + C/20 = 50+1980/20 = 149mA.

Note: In the above example you will receive 2030mA as the answer. The physical limitation is

800mA.

LPP0108IG001 42 Version - Preliminary – 06/20/08

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. Setting BCIMAP# parameters

The BCIMAP# command sets the maps battery voltage and charge current to battery capacity while the

battery is charging. Each battery n may be given a unique BCIMAPn, depending on the battery ID (if

required). Battery capacity is reported as a percentage in 10% steps, no interpolation is given.

When the battery is not charging, BCIPCT# maps battery voltage to battery capacity.

7.6.1. Scope

Default values are intended to be sufficient for general-purpose applications. However, if the battery

capacity mapping needs adjustment for per customer specification, this procedure is one empirical

approach to determining new values.

Production-level calibration not required.

7.6.2. Procedure

The following summary outlines a procedure that requires one complete battery charge and discharge

to determine the battery capacity mappings.

 Choose the BCIMAP# index.

 Set the desired CI charge current <ci_chgireg> for the designated charger.

 Determine the BCIMAP# values up to the <#_ci_elements>.

 Determine the BCIPCT# that corresponds to the BCIMAP index.

 Calculate the BCIMAP# values for the parameters above the index.

 Discharge the battery, determine the remaining BCIPCT# parameters.

 Repeat for each battery and charger.

7.6.3. Choose the BCIMAP# index

Select a BCIMAP# index, <#_ci_elements>, that gives good resolution of capacities in the CI

and CV stages of the charge cycle. If the index is too low, the CI stage will have fewer,

disproportionately large capacity steps, and the CV stage will have more, smaller capacity

steps. If the index is too high, the CI stage will have more, disproportionately small capacity

steps, and the CV stage will have fewer, larger capacity steps. From empirical analysis,

<#_ci_elements> = 7 ± 1

is a good balance giving proportional intervals between the capacity steps in both the CI and

CV stages.

LPP0108IG001 43 Version - Preliminary – 06/20/08

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 Max. charge current <ci_chgireg> [0-255]

USB charger 500mA 160

Wall charger Limited by Triton-Lite

maximum

255

Triton-Lite 800mA 255

Customer charger X Calculate

Note: <ci_chgireg> = [ 0.22 * (CI + ISYS) * 10 + 0 ] * 255 / 1750.

Max value is 255.

Determine the charger # and <ci_chgireg> for that charger.

Charger 1=BCICHG1 is dedicated for USB charging.

Chargers 2-5=BCICHG(2-5) are for any general purpose charger. Set with:

AT$BCICHG#=<type>,<ci_chgireg>,<ov_thr>,< id_low>,<id_high>

Reset or cycle charging with AT$BCIOFF to make new <ci_chgireg> take effect.

Example:

Suppose it is desired to have a USB charge at 100mA when it is the charging source and a

wall charger charge at 800mA when it is the charging source. The system nominal current

Isys=50mA.

<ci_chgireg1> = [ 0.22 * (100 + 50) * 10 + 0 ] * 255 / 1750 = 48

<ci_chgireg2> = [ 0.22 * (800 + 50) * 10 + 0 ] * 255 / 1750 = 272 => 255

AT$BCICHG1=<type>,48,<ov_thr>,< id_low>,<id_high>

AT$BCICHG2=<type>,255,<ov_thr>,< id_low>,<id_high>

7.6.5. Charge empty battery in constant current with target <ci_chgireg>.

Up to 5 different batteries can be independently defined with capacities using the BCIMAP#

and BCIPCT#.

1. Completely discharge the battery n that will be associated with the BCIMAPn and

BCIPCTn.

2. Plug in a charger.

3. When Vbat=3.2V, the Locosto powers on and the modem enumerates a port through

USB. Start logging a text file while the charge state is still precharge 1(PRE).

4. Type the following commands:

6. Stop the log file.

Note: Assuming the <#_ci_elements>=7. Customer may choose different value from

8.2.1 above, and will have to adjust this table accordingly.

Note: Linear interpolation will introduce a slight error in the capacity.

7.6.8. Discharge the battery, determine the remaining BCIPCT# parameters.

Determination of BCIPCT:

1. Start with a fully charged battery.

2. Monitor battery voltage over the full discharge cycle. This can done in-circuit or with a load.

In-circuit is preferred because it will give a better representation of the CI-CV transition point,

and the data can be logged to a text file. Discharging through a load will require a data-logger

to record the discharge voltage, and may not give a clear indication of the CI-CV transition.

7.7. Setting BCIBAT# parameters

7.7.1. Procedure to set the battery ID

1. Choose the bat_ID resistor (ohms) = RID from a table that maps battery capacity

range to a resistance.

2. Calculate the expected ADC reading. ADC4 = RID*.01*1023/1750.

3. Calculate <id_low> = (1023/1837.5) x (0.99 x RID) x 0.008 - 2; 0 if none

4. Calculate <id_high> = (1023/1662.5) x (1.01 x RID) x 0.012 +2; 1023 if none

5. Enter AT$BCIBAT#: <>,<>,<>,<>,<>,<>,<id_low>,<id_high>.

6. Enter AT$RESET: Reset the device, so changed parameters will take effect.

7. Read AT$BAT <>,<bat_id>.

8. Verify bat_id = # of the BCIBAT# corresponding to the range: <id_low>-<id_high>.

7.8. Setting BCITMP# parameters

7.8.1. Scope

Setting the BCITMP# parameters needs to be done by the customer, for each battery with a

thermistor installed. If no thermistor is installed in a battery, set all nine adc parameters to 0.

AT$BCITMP#=-20,60,0,0,0,0,0,0,0,0,0,30

This is a one-time system level design, no factory-level production test or calibration is required.

LPP0108IG001 57 Version - Preliminary – 06/20/08

9. GSM/GPRS Modes of Operation

GSM/GPRS supports many optional services and modes. The Enfora Enabler LPP G module supports

the following GSM/GPRS services:

 Short-Message Services (SMS)

 Class B GPRS Functionality

 Voice communication

9.1. 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.

9.2. Voice Communication

The Enfora Enabler LPP G 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 – LPP0108AT001 has the entire list of commands that can be used to control the voice

functionality.

The Enfora Enabler LPP G module supports four vocoder compression algorithms for voice

communication: Full-Rate (FR), Enhanced Full-Rate (EFR), Half-rate (HR) and Adaptive Multi-rate

(AMR).

LPP0108IG001 58 Version - Preliminary – 06/20/08

9.3. SMS: Short Message Services

 Short Message Services (SMS) is a feature-rich GSM service. The Enfora Enabler LPP G

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)

9.4. SIM Operation

9.4.1. 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 LPP G module that the SIM be configured for the optional

services that are required for the application.

9.5. GPRS Services Supported by the Enfora Enabler LPP G Module

The Enfora Enabler LPP G 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

LPP0108IG001 59 Version - Preliminary – 06/20/08

 Up to Multi-slot 10 Class of Service

9.6. Selecting the GSM Modes of Operation

When provisioning the SIM for the Enfora Enabler LPP G 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

LPP0108IG001 60 Version - Preliminary – 06/20/08

10. Software Interface

10.1. Software Interface

The application sends commands to the Enfora Enabler LPP G module via the 50-pin I/O signal

connector. These commands use the Enabler LPP G Menu System, Enfora AT Command Set and/or

Enfora GSM-GPRS Family API.

The Enfora Enabler LPP G module operates in one of the following modes:

 Command Menu mode: Used for configuring the Enfora Enabler LPP G module. It uses menu

based commands via the serial port for communication. See LPP0108PR001 - Enfora Enabler

LPP G 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.

10.2. 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-LPP G AT Command Set Reference – LPP0108AT001.

10.3. Enfora AT Command Set

For a full description of the AT commands, refer to the Enfora Enabler-LPP G AT Command Set

Reference – LPP0108AT001.

Note: A command description that includes an *asterisk denotes that the GSM service provider

must enable supplementary services functionality before the command is available.
