Power Supply
The main power supply is provided through a double connection. These connections are respectively pins 3 and
4 for the +5V and the pins 1 and 2 for the ground (GND). The pins 6, 21, and 24 are also ground connection in
order to produce a proper ground plane.
A 5V +/-5% - 1A power is strictly required to supply the modem. Otherwise, serious dysfunctions may appear.
However, the modem does not have to constantly deliver 1A current at 5V on this power supply.
This power supply is internally regulated to a nominal value VBATT.

Audio Interface
Two different microphone inputs and two different speaker outputs are supported. The connection can be either
differential or single-ended but using a differential connection in order to reject common mode noise and TDMA
noise is recommended.
Microphone 2 Inputs
The MIC2 inputs are differential ones. They already include the convenient biasing for an electret microphone
(0,5 mA and 2 Volts). This electret microphone can be directly connected on these inputs. The impedance of the
microphone 2 has to be around 2K. These inputs are the standard ones for a handset design while MIC1 inputs
can be connected to an external headset or a hands-free kit.
The gain of MIC2 inputs is internally adjusted. The gain can be tuned from 30dB to 51dB. The connection to the
microphone is direct. The gain can be tuned using the AT+VGR command. See Appendix B: Sourcing Guide for
Connectors and Peripheral Devices.

Microphone 1 Inputs
The MIC1 inputs are differential and do not include internal bias. To use these inputs with an electret
microphone, bias has to be generated outside the ModemModule according to the characteristic of this electret
microphone. These inputs are the standard ones used for an external headset or a hands-free kit. When using a
single-ended connection, be sure to have a very good ground plane, a very good filtering as well as shielding in
order to avoid any disturbance on the audio path. The gain of MIC1 inputs is internally adjusted. The gain can be
tuned from 30dB to 51dB.

Chapter 6 – Application Considerations
General Guidelines for the Use of the ModemModule
Hardware and RF
· Ground plane: MultiTech recommends having a common ground plane for analog, digital and RF grounds.
· Length of the SIM interface lines (15 cm maximum)
· Bias of the Microphone inputs must be properly adjusted when using audio connectors (mic + speaker) 1.
· EMC protection on audio input/output (filters against 900 MHz)
· ESD protection on serial link, …
· Possible spurious emission radiated by the application to the RF receiver in the receiver band
The Antenna
The antenna sub-system and integration in the application is a major issue. It is a major issue in the choice of the
antenna cable (type, length, performances, thermal resistance, etc.)
These elements could affect GSM performances such as sensitivity and emitted power.
The antenna should be isolated as much as possible from the digital circuitry including the interface signals.
MultiTech recommends shielding the terminal. On terminals including the antenna, a poor shielding could
dramatically affect the sensitivity of the terminal. Subsequently, the power emitted through the antenna could
affect the application.
Firmware Upgrade
The ModemModule firmware is stored in flash memory, and it can easily be upgraded. Contact the factory for
details.
Initial Configuration Using Mobile PhoneTools
For Initial configuration of your wireless device, Multi-Tech offers a Windows-based mobile PhoneTools
application.
To load Mobile PhoneTools, click on the Mobile PhoneTools icon on the system CD and follow the on-screen
prompts.

Standards Compliance
Safety Precautions
IMPORTANT!
FOR THE EFFICIENT AND SAFE OPERATION
OF YOUR GSM INTEGRATED MODEM READ
THIS INFORMATION BEFORE USE.
RF Safety
General
Your ModemModule is based on the GSM standard for cellular technology. The GSM standard is spread all over
the world. It covers Europe, Asia and some parts of America and Africa. This is the most used
telecommunication standard. Your modem is actually a low power radio transmitter and receiver. It sends out
and receives radio frequency energy. When you use your ModemModule integrated modem, the cellular system
that handles your calls controls both the radio frequency and the power level of your cellular modem.
Exposure to RF Energy
There has been some public concern about possible health effects of using GSM modems. Although research on
health effects from RF energy has focused on the current RF technology for many years, scientists have begun
research regarding newer radio technologies, such as GSM. After existing research had been reviewed, and
after compliance to all applicable safety standards had been tested, it has been concluded that the product was
fitted for use. If you are concerned about exposure to RF energy there are things you can do to minimize
exposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In addition, you
can reduce RF exposure by operating your cellular modem efficiently by following the below guidelines.
Efficient Modem Operation
For your modem to operate at the lowest power level, consistent with satisfactory call quality:
· If your modem has an extendible antenna, extend it fully. Some models allow you to place a call with
the antenna retracted. However your modem operates more efficiently with the antenna fully extended.
· Do not hold the antenna when the modem is « IN USE ». Holding the antenna affects call quality and
may cause the modem to operate at a higher power level than needed.
Antenna Care and Replacement
Do not use the modem with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor
burn may result. Replace a damaged antenna immediately. Consult your manual to see if you may change the
antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a
qualified technician. Use only the supplied or approved antenna. Unauthorized antennas, modifications or
attachments could damage the modem and may contravene local RF emission regulations or invalidate type
approval.
Appendix A – Safety Precautions & Regulatory Standards Compliance
Wireless ModemModule MTMMC-G-F1 and MTMMC-G-F2 Developer’s Guide 42
General Safety
Driving
Check the laws and the regulations regarding the use of cellular devices in the area where you have to drive as
you always have to comply with them. When using your modem while driving, please: give full attention to
driving, pull off the road and park before making or answering a call if driving conditions so require.
Electronic Devices
Most electronic equipment, for example in hospitals and motor vehicles is shielded from RF energy. However RF
energy may affect some improperly shielded electronic equipment.
Vehicle Electronic Equipment
Check your vehicle manufacturer representative to determine if any on-board electronic equipment is adequately
shielded from RF energy.
Medical Electronic Equipment
Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc...) to
determine if they are adequately shielded from external RF energy. Turn your modem OFF in health care
facilities when any regulations posted in the area instruct you to do so. Hospitals or health care facilities may be
using RF monitoring equipment.
Aircraft
Turn your modem OFF before boarding any aircraft.
· Use it on the ground only with crew permission.
· Do not use it in the air.
To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA) regulations require
you to have permission from a crewmember to use your modem while the aircraft is on the ground. To prevent
interference with cellular systems, local RF regulations prohibit using your modem while airborne.
Children
Do not allow children to play with your modem. It is not a toy. Children could hurt themselves or others (by
poking themselves or others in the eye with the antenna, for example). Children could damage the modem, or
make calls that increase your modem bills.
Blasting Areas
To avoid interfering with blasting operations, turn your unit OFF when in a « blasting area » or in areas posted: «
turn off two-way radio ». Construction crews often use remote control RF devices to set off explosives.
Potentially Explosive Atmospheres
Turn your modem OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem or
its accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily
injuries or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked.
They include fueling areas such as petrol stations; below decks on boats; fuel or chemical transfer or storage
facilities; and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. Do not
transport or store flammable gas, liquid, or explosives, in the compartment of your vehicle that contains your
modem or accessories. Before using your modem in a vehicle powered by liquefied petroleum gas (such as
propane or butane) ensure that the vehicle complies with the relevant fire and safety regulations of the country in
which the vehicle is to be used.
Safety Standards
THIS WIRELESS MODEMMODULE COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS. This
cellular modem meets the standards and recommendations for the protection of public exposure to RF
electromagnetic energy established by governmental bodies and other qualified organizations, such as the
following:
· Directives of the European Community,
· Directorate General V in Matters of Radio Frequency Electromagnetic Energy
Appendix A – Safety Precautions & Regulatory Standards Compliance
Wireless ModemModule MTMMC-G-F1 and MTMMC-G-F2 Developer’s Guide 43
RF Exposures
Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS)
equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), § 2.1091
and § 2.1093 as appropriate.
The MultiTech ModemModule is a GSM (PCS 1900) terminal which operates in the US licensed PCS frequency
spectrum. The device transmits over the 1850-1910 MHz band and receives over the 1930-1990 MHz Band.
Mult-Tech Systems, Inc. certifies that it has determined that the Modem complies with the RF hazard
requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart
E of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of the
equipment in accordance with all instructions provided.
The Modem is designed for and intends to be used in fixed and mobile applications. "Fixed" means that the
device is physically secured at one location and is not able to be easily moved to another location. "Mobile"
means that the device is designed to be used in other than fixed locations and generally in such a way that a
separation distance of at least 20cm is normally maintained between the transmitter's antenna and the body of
the user or nearby persons. The Modem is not designed for or intends to be used in portable applications (within
20 cm of the body of the user) and such uses are strictly prohibited. To ensure that the unit complies with current
FCC regulations limiting both maximum RF output power and human exposure to radio frequency radiation, a
separation distance of at least 20cm must be maintained between the unit's antenna and the body of the user
and any nearby persons at all times and in all applications and uses. Additionally, in mobile applications,
maximum antenna gain must not exceed 3 dBi (to comply with Section 24.232(b) and is limited to 7 dBi for fixed
applications. Finally, the tune-up procedure for the O9EM2113 ensures that the maximum RF output power of
the device does not exceed 30.0 dBm within the variations that can be expected due to quantity production and
testing on a statistical basis.
Instructions to OEMs
The MultiTech product manual includes specific warnings and cautions in order to ensure that OEMs are aware
of their responsibilities, with regards to RF exposure compliance, for products into which the modem is
integrated. With this guidance, the OEM will be able to incorporate into their documentation the necessary
operating conditions and warnings.
OEMs need to provide a manual with the ‘’final’’ product that clearly states the operating requirements and
conditions and that these must be observed to ensure compliance with current FCC RF exposure requirements /
MPE limits (see the “RF Exposures” section above). This will enable the OEM to generate (and provide the end-
user with) the appropriate operating instructions, warnings and cautions, and/or markings for their product.

GSM Antenna
The integrated modem antenna connector is a MMCX connector. The MMCX connector incorporates a 'Snap On'
latching action in order to make the connection easier with an excellent RF performance. An additional
advantage is its small physical size which is 50% of the standard MCX connector.
This type of connector is suitable for the standard ranges of flexible and semi-rigid cables. The characteristic
impedance of the MMCX coaxial connector is 50 ohm. The antenna manufacturer must guarantee that the
antenna will be working according to the radio characteristics presented in the table below.
