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 IIG 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 consumerserviceable components.

2.0 Regulatory Compliance FCC

2.1 Integration Considerations and Installation Requirements

The Enabler IIG 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 IIG 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.

 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).

GSM0128IG001 5 Revision Draft – 9/22/08

Page 7

 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:

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

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

Substitute MIVGSM0108 for the quad-band modem label.

 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.

The transmitter and antenna must not be collocated

4.7 General layout guidelines for Enfora GSM modules

To ensure lowest possible EMI emission, maximum thermal conduction and mechanical integrity, all metal tabs on the GSM module shield must be soldered down on to a continuous ground plane. The PCB trace that feeds the RF output port should be 50ohm characteristic impedance, coplanar, or routed into internal layers to keep the top layer continuous around and underneath the device. Provide ample ground vias around metal tabs, the RF trace and launch pad. If possible, keep I/O and power traces away from the RF port.

6.6 Circuit Protection

Other than the basic low level ESD protection within the module’s integrated circuits (typically 2000 V), the Enabler IIG 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/Transorb devices) should be added to all signals that leave the host board. This includes V

Series resistors (typically 47 ) can also be added in series with data lines to limit the peak current during a voltage excursion.

excursions that exceed the specified operating parameters.

Page 29

6.7.2 RF Connector

The Enabler IIG utilizes an 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 IIG module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the uplink currents are shown in Tables5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The

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.

GSM0128IG001 28 Revision Draft – 9/22/08

Page 30

6.8.2 Ring Indicate (Pin 49)

The Enabler IIG 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 three (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.

Ring

When a Fax or 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.

Ring

An incoming SMS can be indicated by an Unsolicited Result Code (URC) which causes the Ring line to go

low for 1 second only. Using the AT+CNMI command, the Enabler IIG can be configured to send or not to send URCs upon the receipt of SMS. See Enfora GSM0128AT001 – Enfora Enabler IIG AT Command

6.8.3 Radio Power/Reset (Pin 22)

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 although this 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 must not be used to “power off” the device, but only as a last resort wherein there is no response from the module.

Controlling the Reset signal must only performed 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.

The Reset pin can also be monitored as a system on/off indication. When the modem is powered on during a normal operating state, this pin will be set high. When the modem is powered down or in the “off” state, this pin will be low. Any monitoring circuit MUST be high impedance, such as a logic gate or microprocessor input.

6.8.4 Using the Power Control Signal (Pin 24)

The input is equivalent to a “phone ON-button”. A failing-edge on this Active-Low input will switch ON the module or switch OFF the module after a delay

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.

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.

Pulling the PWR_CTL line on the Enabler IIG LOW for at least 50ms (after Vbat is applied and stabilized) is required to turn it ON. Section 6.8.43 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.

To enable the module to switch-OFF via PWR_CTL one must set AT$OFFDLY to a value other than 0. The valid range is 100 to 1000 milliseconds.

6.8.4.1 Turning ON the Enabler IIG

6.8.4.2 Turni ng OFF the Enabler IIG

The Enabler IIG can be turned OFF by either a low pulse on the PWR_CTL line or, or by a software command (ATt$OFF - see AT command guide for further information). Section 6.8.4.3 describes various ways to provide the signal.

6.8.7 Serial Interface (9 Pin I/F) (Pins 41, 43, 45, 47, 49, 51, 53, 55, 57)

The modem provides a standard 16550 UART serial interface to the host. The data interface operates at CMOS level. The Enabler IIG 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.

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 , 300, 600, 1200, 2400, 4800, 7200, 9600, 14400, 19200, 28800, 33900, 38400, 57600, ,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, and connect DTR and RTS to GND.

The electrical characteristics for the I/O lines are the same as the General Purposes Input/Output (GPIO) lines.

6.10 Subscriber Identity Module (SIM) Carrier (Pins 48, 52, 54, 55)

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 IIG 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.

6.10.1 SIM Integration for the Enfora Enabler IIG Module

The Enabler IIG default configuration does not include an on-board SIM carrier. Some versions may include an on-board SIM carrier. Enfora provides a separate product SKU for the Enabler IIG module with the integrated SIM carrier.

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 IIG 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 IIG Module

The Enfora Enabler IIG 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

 The GSM SIM can have multiple telephone numbers.

8.3 GPRS Services Supported by the Enfora Enabler IIG Module

The Enfora Enabler IIG 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

9.0 Software Interface

9.1 Software Interface

The application sends commands to the Enfora Enabler IIG module via the 60-pin I/O signal connector. These commands use the Enfora AT Command Set and/or Enfora’s Packet API.

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

 Command mode: Used for configuring the Enfora Enabler IIG module, for interrogating the GSM

network, and for placing and receiving calls. It uses the AT command set via the serial port for communication.

 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

GSM0308UG001 - Enfora GSM-GPRS Family API Reference. GSM0308UG001 - Enfora GSM-GPRS Family API Reference 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 IIG Integration Toolkit.

The AT command driver of the Enfora Enabler IIG 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 IIG module.

 In response to the commands received from the CPE, the Enfora Enabler IIG module sends characters

(AT commands) to the CPE.

 Various events can also trigger the Enfora Enabler IIG 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>

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 GSM0128AT001 – Enfora Enabler IIG AT Command Set.

AT See AT Command Manual 0X0D

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 IIG module is designated as:

Entry

 The data exchange from the Enfora Enabler IIG 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.

11.0 Integration and Testing

The Enfora Enabler IIG 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 IIG 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

Integrating the Enfora Enabler IIG 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 IIG 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

Primary and secondary serial Interfaces Reset Interface Audio/Microphone Interface

The maximum line length of the SIM interface is 25.4 cm (10 inches).

The Enfora Enabler IIG 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.

The Enfora Enabler IIG module uses a 3 V digital interface. The RS-232 signals must be level-shifted to get standard levels. These signals must be ESD-protected.
