1.0 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 II-E product to open flames.
• Ensure that liquids do not spill into 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.
2.0 Regulatory Compliance FCC
2.1 Integration Considerations and Installation Requirements
The Enabler II-E OEM GPRS 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.
• In order to use the Enabler II-E without additional FCC certification approvals, the installation must
meet the following conditions:
• For the transmitter to meet the MPE categorical exclusion requirements of 2.1091, the ERP
must be less than 1.5 watts for personnel separation distance of at least 20 cm (7.9 in).
Therefore, the maximum antenna gain cannot exceed +3.3dBi. If greater than 1.5 watts exists,
then additional testing and FCC approval is required.
• If used in a "portable" application such as a handheld 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:
• 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).
Integration Guide
Version 0.03
EDG0100PB003 Page 6 0.03 – 4/19/05
• 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: TBD
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: TBD
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.
• 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.

6.6 Circuit Protection
Other than the basic low level ESD protection within the module’s integrated circuits (typically 2000 V), the
Enabler II-E does not have any protection against ESD events or other excursions that exceed the specified
operating parameters.
The only exception is that the remote SIM lines on the main I/O connector do have additional ESD protection
that should handle standard human-model contact ESD events.
Generally, ESD protection (typically TVS/Transzorb devices) should be added to all signals that leave the
host board. This includes VBAT/VCC.
Series resistors (typically 47 Ω) can also be added in series with data lines to limit the peak current during a
voltage excursion.
!
Caution – It is the Integrator’s responsibility to protect
the Enabler II-E from electrical disturbances and
excursions that exceed the specified operating
parameters.
6.7 Antenna
The Enabler II-E utilizes an ultra Miniature Coaxial Interconnect from Sunridge (MCB-ST-00T) as the on-
board antenna connector. A compatible mating connector is the Sunridge MCB2-xx-xx-xxx-x series
component. The cable assembly is made to order. Maximum stack height of cable connector and PCB
connector is 2.0 mm.

6.8 Control Connector Signal Descriptions and Functions
6.8.1 Input Power
The Enfora Enabler II-E module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the
uplink currents are shown in Tables 5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The
VCC lines (pins 1 to 6) should be connected on the application board.
!
The uplink burst will cause strong ripple on the voltage
lines and should be effectively filtered. It is recommended
that 1000 to 2000 uF of capacitance be placed as close to
the modem I/O connector as possible.
It should be noted that the input voltage level should not
drop below the minimum voltage rating under any
circumstances, especially during the uplink burst period.

Version 0.03
EDG0100PB003 Page 26 0.03 – 4/19/05
6.8.2 Ring Indicate
The Enabler II-E module is capable of using the Ring line to discern the type of incoming call. The indicator
can be monitored via a hardware line available on the 60 pin I/O signal connector. The Ring Indicator pin is
#49.
The function of the Ring line depends on the type of the call received.
When the module is receiving a voice call, the Ring line goes low for 1 second and high for another 2
seconds. Every 3 seconds the ring string is generated and sent over the Receive (Data Out) (Rx) line. If
there is a call in progress and call waiting is activated for a connected handset or hands free device, the
Ring pin switches to ground in order to generate acoustic signals that indicate the waiting call.
When a data call is received, Ring goes low and will remain low. Every 3 seconds a ring string is generated
and sent over the Receive (Data Out) (Rx) line.
An incoming SMS can be indicated by an Unsolicited Result Code (URC) causing the Ring line to go low for
1 second only. Using the AT+CNMI command, the Enabler II-E can be configured to send or not to send
URCs upon the receipt of SMS. See Enfora Enabler-IIE AT Command Set Reference -
EDG0100PB004MAN.

6.8.3 Radio Power/Reset (Pin 22)
A pulse on this Active-High input resets/restarts the module. This input has a “weak pull-down” resistor
internal to the module and can be left open-circuit or grounded if it is not going to be used. To initiate a
reset, provide a high-pulse of at least 50 ms duration.

6.8.4 Using the Power Control Signal
The input is equivalent to the “phone ON-button”. This is a hardware-controlled pin on power-up. It must
be grounded momentarily or continuously to start the modem. Subsequent signals to this pin (active
high-to-low transition) will cycle power to the module. When the modem is OFF, a high-to-low pulse of >
100 mS will turn the modem ON. When the modem is ON, a high-to-low pulse of XXX mS will deregister
from the network and turn the modem OFF. XXX is > 100 mS and can be configured via AT Command for
pulses up to 10000 mS. 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, see Section 6.8.5.

6.8.7 Serial Interface (9 Pin I/F) (See table in section 6.5.1 I/O Connector Pin Assignments)
The modem provides a standard 16550 UART serial interface to the host. The data interface operates at
CMOS level.
The Enabler II-E is designed to be used like a DCE device. RxData is the serial data from the modem to the
host. TxData is the serial data from the host to the modem.
Figure 9 Enabler II-E Serial Interface
This data may contain 7 or 8 data bits, 1 or 2 stop bits, even/odd/no parity bits. The baud rate may be
adjusted to 75, 150, 300, 1200, 2400, 4800, 9600,19200, 38400, 57600, or 115200 bits per second.
Default settings are 8 data, 1 stop, no parity, and 115200 baud. DTR may be used to force the modem into
AT command mode from online data mode (See AT Command Document, command AT&D). RTS and CTS
may be used for hardware handshaking. DSR is always active (connected to ground) while the modem is
on. RING may be used to alert the host to a variety of incoming calls.
For a minimal implementation, connect RxData and TxData to the COM port serial data lines, connect DTR
and RTS to GND.

6.9 Subscriber Identity Module (SIM) Carrier
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 II-E module. The SIM must be obtained from the
GSM service provider and must be provisioned by the operator for data and/or voice. Always
take care to protect the SIM: the GSM terminal will not operate without the SIM installed.
The SIM provides the IMSI for authentication. To gain access to the GSM network, the network
must recognize the IMSI number, and the terminal must be able to properly decrypt the data sent
by the network. The SIM also serves as a buffer for SMS messages, storing the message for
transmission until a radio link is available and buffering received messages until retrieved.
6.9.1 SIM Integration for the Enfora Enabler II-E Module

7.0 Modes of Operation
GSM/GPRS/EGPRS supports many optional services and modes. The Enfora Enabler II-E module supports
the following services:
• Circuit-switched data
• Short-Message Services (SMS)
• Class B/C GPRS Functionality
• Voice communication
• EGPRS
7.1 Enabling the Transmission Modes for the GSM/GPRS/EGPRS Services
Each of the GSM/GPRS/EGPRS services has two modes that can be enabled separately:
• Mobile-originated (MO): allows the making of a service request (such as, making a telephone call or
sending an SMS)
• Mobile-terminated (MT): allows receiving a service request (such as receiving a telephone call or an
SMS)
Note: Contact your local GSM operator to ensure that the services and modes have been provisioned for
the SIM.
7.2 Voice Communication
The Enfora Enabler II-E module has full voice capabilities, provided the necessary connections have been
made for the speaker and microphone pins on the 60-pin I/O connector. The Enfora Enabler-IIE AT
Command Set Reference - EDG0100PB004MAN has the entire list of commands that can be used to
control the voice functionality. The quick start guide in this manual provides a basic command set that can
be used to initialize and test the voice functionality.
The Enfora Enabler II-E module supports three standard vocoder compression algorithms for voice
communication: Full-Rate, Enhanced Full-Rate (EFR), and Half-rate (HR) and also provides support for the
Adaptive Multi-Rate (AMR) codec.
7.3 Circuit-Switched Data
In this mode, the Enfora Enabler II-E module supports both of the connection modes of transmission that are
provided by GSM:
• Non-Transparent mode delivers a constantly low error rate but with a non-guaranteed throughput or
delay. The Non-Transparent service provides a performance that is closest to using a modem over a
fixed Public Switched Telephone Network (PSTN) line.
Note: All GSM service providers may not support Transparent mode. In those cases, the Enfora Enabler II-
E module can be configured to switch automatically to Non-Transparent mode. This capability depends on
the settings in the AT+CBST command.

8.0 SIM Operation
8.1 Provisioning the SIM
The SIM can support optional features or services. Most operators typically configure the SIM to
send/receive voice calls and to receive SMS; however, some may require an additional tariff to enable the
SIM to send SMS. The transmission of circuit switched and GPRS data are also additional services that
may be required to allow the service:
• Mobile-originated (MO): allows making a service request (such as, making a call or sending an SMS)
• Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone call or an SMS)
It is imperative for the Enfora Enabler II-E module that the SIM be configured for the optional services that
are required for the application.
8.2 GSM Services Supported by the Enfora Enabler II-E Module
The Enfora Enabler II-E module supports four GSM services (modes of operation) that must be enabled by
the operator:
• Voice calls (MO and MT): requires a telephone number
• SMS (MO and MT): uses the telephone number for Voice
• Circuit-switched data calls (MO and MT): requires a telephone number
• The GSM SIM can have multiple telephone numbers.
8.3 GPRS Services Supported by the Enfora Enabler II-E Module
The Enfora Enabler II-E module supports the following GPRS (modes of operation) that must be enabled by
the operator:

The application sends commands to the Enfora Enabler II-E module via the I/O signal connector.
These commands use the Enfora AT Command Set and/or Enfora’s Packet API.
The Enfora Enabler II-E module operates in one of the following modes:
• Command mode: Used for configuring the Enfora Enabler II-E module, for interrogating the GSM
network, and for placing and receiving calls. It uses the AT command set via the serial port for
communication.
• On-line mode: Used after a circuit-switched data call has been established. Data is passed between
the Enfora Enabler II-E module and the controlling application without command interpretation. The
only AT command that is interpreted in On-line mode is the +++ command. (This command places the
Enfora Enabler II-E 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 UDP-API Reference GSM0102PB002MAN. Enfora GSM-GPRS Family Modem
Control Library Reference GSM0000PB006MAN provides detail of the UDP Modem Control Library that
has three levels: port , messaging, and modem libraries. Each of the three levels contains one or more
libraries. For example, the port libraries layer has UDP PPP Port, UDP Socket Port, and COM Port
libraries. All libraries are provided as a part of the Enfora Enabler II-E Integration Toolkit.
The AT command driver of the Enfora Enabler II-E 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 Enfora Enabler II-E module.
• In response to the commands received from the CPE, the Enfora Enabler II-E module sends characters
(AT commands) to the CPE.
• Various events can also trigger the Enfora Enabler II-E module to send characters (AT commands) to
the CPE.
9.2 Format for the AT Commands
The general format of the command line is: <prefix> <command> <CR>
<prefix> AT
<command> See AT Command Manual
<CR> 0X0D
The prefix AT obtains synchronization, identifies the character parameters, and indicates that a command
may be in the following characters.
AT commands are not case sensitive: use either capital letters or lower-case letters for the AT command.
Note: Some AT Command parameter values ARE case sensitive and are documented in the Enfora
Enabler-IIE AT Command Set Reference - EDG0100PB004MAN.

provided by the Messaging Library, the modem library maintains a modem parameter database. In order to
maintain the parameter database, the modem library requires more memory than the other libraries. This
makes the library unsuitable for some of the micro controller programming. However, it is a good library to
use by applications in a personal computer or a PDA. It allows the programmer to develop host applications
for the modem quickly.

10.1.2 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 Enfora Enabler II-E module is designated as:
Entry
• The data exchange from the Enfora Enabler II-E 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.

EDG0100PB003 Page 47 0.03 – 4/19/05
10.1.3 Initial Response to the AT Command
After power is applied to the Enfora Enabler II-E module, the module performs a power-up self-test. The
self-test completes within one (1) second. When queried with the AT command, the Enfora Enabler II-E
module responds with one of the following result codes:
• OK signifies that the Enfora Enabler II-E module is ready, that it correctly interprets the AT command,
and that it has executed the command.
• ERROR signifies that the Enfora Enabler II-E module does not understand the command or that the
command is invalid.
Entry AT
Response OK Command valid: module is ready
The Enfora Enabler II-E module must be in AT Command mode (please refer to section 10.3 GPRS Packet
Examples for packet mode initialization and setup) when any command is entered (with the exception of the
online escape sequence). Commands entered when the module is in On-line mode are treated as data, and
are transmitted as such to the receiving module. i.e. If the module is in PPP or SLIP mode, AT commands
cannot be entered.
10.1.4 Sending an Initialization String to the Enfora Enabler II-E 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

11.0 Integration and Testing
The Enfora Enabler II-E module has been designed to minimize the amount of time required for integration
and testing the application. By being fully certified by the appropriate bodies, the Enfora Enabler II-E
module provides seamless integration into the GSM network.
The integration issues for the application can be narrowed to the utilization of the AT commands and the use
of the GSM functionality. Coverage and signal quality may be evaluated by using the RSSI commands.
Additional network information can be determined by using AT commands.
Integration of the GPRS Packet capabilities is more complicated than using AT command sequences to
initiate the connection and begin transferring data. The following Application Notes should be used to
integrate the GPRS packet capabilities:
GSM0000AN002 - Enabler-G PPP Configuration for Windows 2000
GSM0000AN008 - Enabler-G PPP Configuration for Windows XP

Integrating the Enfora Enabler II-E Module
Note: Generally, all interfaces that are externally available to the end user need to be ESD-
conditioned and terminated in some way. Many of these interfaces should not be connected with
power applied.
At the highest level, this is done using some type of GSM test equipment (such as, Racal 6103E), a
computer, and a serial interface tester. The GSM test equipment must be able to simulate a GSM
call and measure the key parameters related to the module.
Additionally, the serial interfaces and some minimal SIM functionality can be verified by sending AT
commands to the Enfora Enabler II-E module.
All of these conditions need to be verified at ambient as well as extreme conditions.
As part of integration, each of the following interfaces must be verified:
Information Recommendations
SIM The maximum line length of the SIM interface is 25.4 cm (10 inches).
The Enfora Enabler II-E 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.

with FCC requirements for safe operation regarding exposure to RF radiation.
Depending upon the application and type of product into which the Enfora Enabler II-E 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 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 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.
