Description
Type
Reset. This signal is used to force a reset procedure by providing low level during
at least 500µs. This signal is considered an emergency reset only. A reset procedure is already driven by an internal hardware during the power-up sequence. This signal can also be used to provide a reset to an external device. It then acts as an output. If no external reset is necessary, this input can be left open. If used (emergency reset), it has to be driven by an open collector or an open drain.
Ground Request to Send. The –RTS signal is used for hardware flow control. Received Data. The modem uses the –RXD line to send received data to the
DTE and to send modem responses to the DTE. Transmitted Data. The DTE uses the –TXD line to send data to the modem or to transmit commands to the modem. Ring Indicate. –RI output ON (low) indicates the presence of an ON segment of a ring signal. Data Set Ready. The –DSR indicates modem status to the DTE. –DSR OFF (high) indicates that the DTE is to disregard all signals appearing on the interchange circuits except Ring Indicator (–RI). It reflects the status of the local data set and does not indicate an actual link with any remote data equipment. Clear To Send. –CTS is controlled by the modem to indicate whether or not the modem is ready to transmit data. –CTS ON, indicates to the DTE that signals presented on TXD will be transmitted. –CTS OFF indicates to the DTE that it should not transfer data across the interface on TXD. Data Carrier Detect. –DCD output is ON (low) when a data connection is established. Data Terminal Ready (Active Low). The –DTR input is turned ON (low) by the DTE when the DTE is ready to transmit or receive data. –DTR ON prepares the modem to be connected, and, once connected, maintains the connection. –DTR OFF places the modem in the disconnect state.

Considerations
General Guidelines for the Use of the SocketModem
Hardware and RF
· Ground plane: Multi-Tech recommends having a common ground plane for analog, digital, and
RF grounds.
· 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. Multi-Tech 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.
Soldering and Cleaning the SocketModem
The pins of the SocketModem may be hand soldered or wave soldered. If wave soldered, the temperature on the top of the SocketModem must not exceed 100° C.
There should be no solvent or water washing of the SocketModem. Do not use a hot air gun on the SocketModem.
Firmware Upgrade
The SocketModem 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 the Mobile PhoneTools icon on the system CD and follow the on-screen prompts.

Safety Precautions
IMPORTANT!
FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM INTEGRATED MODEM READ THIS INFORMATION BEFORE USE.
RF Safety
General
Your SocketModem 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 SocketModem integrated modem, the cellular system, which 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.
16
Page 17
Appendix A – Safety Precautions and Regulatory Standards Compliance
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 must comply with these laws and regulations. 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 crew member 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 gas stations; below deck 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, which 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.

Appendix A – Safety Precautions and Regulatory Standards Compliance
General Safety Standards
THIS WIRELESS SOCKETMODEM 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 that have been 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
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 Multi-Tech SocketModem 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 1930­1990 MHz Band. Multi-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 intended 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 20 cm is normally maintained between the transmitter's antenna and the body of the user or nearby persons. The Modem is not designed for or intended 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 20 cm 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 Multi-Tech 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.
