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. MIC2NMIC2PC1C1 = 22pF to 100 pF33 pF recommended

11 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.

The antenna system must be the same type with similar in-band and out-of-band radiation patterns and maintain the same specifications. FCC Requirements Note: The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 MHz for mobile operating configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as defined in 2.1091 and 1.1307 of the rules for satisfying RF exposure compliance.

13 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.

20 New Zealand Telecom Warning Notice 1. The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has accepted that the item complies with minimum conditions for connection to its network. It indicates no endorsement of the product by Telecom, nor does it provide any sort of warranty. Above all, it provides no assurance that any item will work correctly in all respects with another item of Telepermitted equipment of a different make or model, nor does it imply that any product is compatible with all of Telecom’s network services. This equipment is not capable under all operating conditions of correct operating conditions of correct operation at the higher speed which it is designated. 33.6 kbps and 56 kbps connections are likely to be restricted to lower bit rates when connected to some PSTN implementations. Telecom will accept no responsibility should difficulties arise in such circumstances. 2. Immediately disconnect this equipment should it become physically damaged, and arrange for its disposal or repair. 3. This modem shall not be used in any manner which could constitute a nuisance to other Telecom customers. 4. This device is equipped with pulse dialing, while the Telecom standard is DTMF tone dialing. There is no guarantee that Telecom lines will always continue to support pulse dialing. Use of pulse dialing, when this equipment is connected to the same line as other equipment, may give rise to 'bell tinkle' or noise and may also cause a false answer condition. Should such problems occur, the user should NOT contact the Telecom Faults Service. The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing and is readily available on almost all New Zealand telephone exchanges. 5. Warning Notice: No '111' or other calls can be made from this device during a mains power failure. 6. This equipment may not provide for the effective hand-over of a call to another device connected to the same line. 7. Some parameters required for compliance with Telecom’s Telepermit requirements are dependent on the equipment (PC) associated with this device. The associated equipment shall be set to operate within the following limits for compliance with Telecom’s Specifications: For repeat calls to the same number: • There shall be no more than 10 call attempts to the same number within any 30 minute period for any single manual call initiation, and • The equipment shall go on-hook for a period of not less than 30 seconds between the end of one attempt and the beginning of the next attempt. For automatic calls to different numbers: • The equipment shall be set to ensure that automatic calls to different numbers are spaced such that there is no less than 5 seconds between the end of one call attempt and the beginning of another. 8. For correct operation, total of the RN’s of all devices connected to a single line at any time should not exceed 5.

27 Board Components Jumper Description JP1 Mutes the speaker. Default positions are 1 and 2 (speaker is not muted). JP2 Ties the TX and RX clock lines together. Default positions are 1 and 2 (transmit and receive clock act independently). JP3 Sets the data rate. NORMAL sets the data rate at 250kbps. H.S. (high speed serial communications) sets the data rate at 1Mbps. JP4 Testing interface (debugging) for the RS-232 signals. JP5 JP5 acts as a replacement for pin 45 when pin 45 is used for another function. JP7 Testing interface (debugging) for the serial TTL signals. JP9 JP9 is the 5V / 3.3V regulator. The factory default operating voltage is 3.3V. Warning – Be sure that the 5V / 3.3V jumper is set to match the requirements of your SocketModem. If this jumper is set incorrectly, damage to the SocketModem and/or the Test/Demo card could result. Caution – Use only the provided Multi-Tech Systems, Inc. transformer with the Test/Demo board. Use of any other power source will void the warranty and will likely damage the Test/Demo board and the SocketModem. The transformer connector is keyed to prevent improper connection to the Test/Demo board. JP12 JP12 allows you to select either the internal 5V regulator (INT 5V) or to choose EXT 5V. For the EXT 5V, you can use your own external 5V power source and plug it into J7. JP13 Set either 5V or 3.3V for USB_VBUS line (supplied by the VCC of the USB jack). JP14 Internal testing. JP15 JP15 disconnects pin 45 from SLP with JP5 (the RS-232 driver sleep mode). JP16 JTAG header. JP17 Mosquito header.
