The RF connector on the SocketModem GPRS is a UFL standard type. See Chapter 1 for Antenna System details.
Microphone Inputs
The MIC 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
has to be around 2K. These inputs are the standard ones for a handset design.
The gain of the MIC inputs is internally adjusted. The gain can be tuned from 30dB to 51dB. The connection to the
microphone is direct.

Changing the Quad Band
The SocketModem Cell and the SocketModem iCell both support quad band frequencies (850/1900/900/1800 MHz).
In reality, these products operate like dual, dual-band devices. In other words, they can be configured for 850/1900 or
900/1800 MHz. They do not auto-seek the local area frequency.
Build Options
These wireless modems can be ordered with the default set to 850/1900 MHz or 900/1800 MHz.
• 850/1900 MHz – The wireless modem defaulting to 850/1900 MHz is the default build option.
• 900/1800 MHz – The wireless modem defaulting to 900/1800 MHz is identified with -ED in the product
ordering number which signifies European default.
Changing the GSM Band
If for any reason, such as moving the modem from one geographical area to another, you want to change the
band, you can accomplish this by using the +WMBS AT Command.
Steps for Changing the GSM Band
Use a terminal application such as HyperTerminal for entering the AT Command.
1. To open HyperTerminal, click Start. Then select Programs > Accessories > Communications. Then
click HyperTerminal.
2. When the command window opens, type AT+WMBS=<Band><Param>. Press Enter.
• For <Band>, enter the option you desire:
4 = Dual-band mode 850/1900MHz
5 = Dual-band mode 900/1800MHz
• For <Param>, enter the option you desire:
0 = Modem must be reset in order to use the specified band(s). This is the default.
1 = Modem restarts immediately using the specified band(s).
Example: AT+WMBS=4,0. Press Enter.

Chapter 3 – Design Considerations
Noise Suppression Design Considerations
Engineering noise-suppression practices must be adhered to when designing a printed circuit board (PCB)
containing the SocketModem module. Suppression of noise is essential to the proper operation and performance
of the modem itself and for surrounding equipment.
Two aspects of noise in an OEM board design containing the SocketModem must be considered: onboard/off-
board generated noise that can affect digital signal processing. Both on-board and off-board generated noise that
is coupled on-board can affect interface signal levels and quality. Of particular concern is noise in frequency
ranges affecting modem performance.
On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted offboard is a
separate, but equally important, concern. This type of noise can affect the operation of surrounding equipment.
Most local government agencies have stringent certification requirements that must be met for use in specific
environments.
Proper PC board layout (component placement, signal routing, trace thickness and geometry, etc.) component
selection (composition, value, and tolerance), interface connections, and shielding are required for the board
design to achieve desired modem performance and to attain EMI certification.
Other aspects of proper noise-suppression engineering practices are beyond the scope of this designer guide.
The designer should consult noise suppression techniques described in technical publications and journals,
electronics and electrical engineering text books, and component supplier application notes.
PC Board Layout Guidelines
In a 4-layer design, provide adequate ground plane covering the entire board. In 4-layer designs, power and
ground are typically on the inner layers. All power and ground traces should be 0.05 inches wide.
The recommended hole size for the SocketModem pins is 0.036 in. +/-0.003 in. in diameter. Spacers can be used
to hold the SocketModem vertically in place during the wave solder process. A spacer should be placed on pin 32
and pin 64 of the SocketModem. A suggested part number for the spacer is BIVAR 938-0.130 for P1 (0.310in)
option SocketModems. The spacers can be left on permanently and will not effect operation.
All creepages and clearances for the SocketModem have been designed to meet requirements of safety
standards EN60950 or EN60601. The requirements are based on a working voltage of 125V or 250V. When the
recommended DAA* circuit interface is implemented in a third party design, all creepage and clearance
requirements must be strictly followed in order to meet safety standards. The third party safety design must be
evaluated by the appropriate national agency per the required specification.
User accessible areas: Based on where the third party design is to be marketed, sold, or used, it may be
necessary to provide an insulating cover over all TNV exposed areas. Consult with the recognized safety agency
to determine the requirements.
Note: Even if the recommended design considerations are followed, there are no guarantees that a particular
system will comply with all the necessary regulatory requirements. It is imperative that specific designs be
completely evaluated by a qualified/recognized agency.
*DAA stands for Data Access Arrangement. DAA is the telephone line interface of the module.
Electromagnetic Interference (EMI) Considerations
The following guidelines are offered specifically to help minimize EMI generation. Some of these guidelines are
the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order
to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major
sources of EMI and how to reduce them to acceptable levels.
1. Keep traces carrying high frequency signals as short as possible.
2. Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for
ground and power distribution.
14
3. Decouple power from ground with decoupling capacitors as close to the SocketModem module power pins as
possible.
4. Eliminate ground loops, which are unexpected current return paths to the power source and ground.
5. Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series inductors,
common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to decoupling
power lines; however, telephone line decoupling may be more difficult and deserves additional attention. A
commonly used design aid is to place footprints for these components and populate as necessary during
performance/EMI testing and certification.
6. Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple power
lines are similar to decoupling telephone lines.
7. Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.
8. Locate cables and connectors so as to avoid coupling from high frequency circuits.
9. Lay out the highest frequency signal traces next to the ground grid.
10. If a multilayer board design is used, make no cuts in the ground or power planes and be sure the ground
plane covers all traces.
11. Minimize the number of through-hole connections on traces carrying high frequency signals.
12. Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns
are better.
13. On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the board to
traces carrying high frequency signals. This will be effective as a high frequency ground return if it is three times
the width of the signal traces.
14. Distribute high frequency signals continuously on a single trace rather than several traces radiating from one
point.
Electrostatic Discharge Control
All electronic devices should be handled with certain precautions to avoid damage due to the accumulation of
static charge.
See the ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – a document “for the Development of an
Electrostatic Discharge Control for Protection of Electrical and Electronic Parts, Assemblies and Equipment.” This
document covers ESD Control Program Administrative Requirements, ESD Training, ESD Control Program Plan
Technical Requirements (grounding/bonding systems, personnel grooming, protected areas, packaging, marking,
equipment, and handling), and Sensitivity Testing.
Multi-Tech Systems, Inc. strives to follow all of these recommendations. Input protection circuitry has been
incorporated into the Multi-Tech devices to minimize the effect of this static buildup, proper precautions should be
taken to avoid exposure to electrostatic discharge during handling.
Multi-Tech uses and recommends that others use anti-static boxes that create a faraday cage (packaging
designed to exclude electromagnetic fields). Multi-Tech recommends that you use our packaging when returning
a product and when you ship your products to your customers.

9. This product must be disconnected from its power source and telephone network interface when servicing.
Wireless Safety
General Safety
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.
RF Safety
The remote modems are wireless cellular telephones devices. It is important to follow any special
regulations regarding the use of radio equipment due in particular to the possibility of Radio Frequency (RF)
interference.
Caution: A separation distance of at least 20 cm must be maintained between the modem 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. In particular, if using a Yagi antenna, it must be
in a location that prevents public exposure to the radiation limits being exceeded. Check your local
standards regarding safe distances, etc.
• Wireless modems in an ATM in, for example, a hospital environment and any other place where medical
equipment may be in use, may be a hazard. This statement also applies to inadequately protected
personal medical devices such as hearing aids and pacemakers.
• Operation of a wireless modem close to other electronic equipment may also cause interference if the
equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.
• The modems must not be operated around gasoline or diesel-fuel.
RF Interference Safety
It is important to follow any special regulations regarding the use of radio equipment due in particular to the
possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully.
• Switch OFF your Wireless MultiModem when in an aircraft. The use of cellular telephones in an aircraft
may endanger the operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe
this instruction may lead to suspension or denial of cellular telephone services to the offender, or legal
action or both.
• Switch OFF your Wireless MultiModem when around gasoline or diesel-fuel pumps and before filling your
vehicle with fuel.
16
• Switch OFF your wireless device in hospitals and any other place where medical equipment may be in
use.
• Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting
