DESIGN CONSIDERATIONS
Design Considerations
USB Design
Multi-Tech recommends that you review Intel's High Speed USB Platform Design Guidelines for information about
USB signal routing, impedance, and layer stacking. Also:
■ Shield USB cables with twisted pairs (especially those containing D+/D-).
■ Use a single 5V power supply for USB devices. See the Power Draw section in your model’s Device Guide for current (ampere) requirements.
■ Route D+/D- together in parallel with the trace spacing needed to achieve 90 ohms differential impedance for the USB pair and to maintain a 20 mil space from the USB pair and all other signals.
■ If power is provided externally, use a common ground between the carrier board and the device.
Noise Suppression Design
Adhere to engineering noise-suppression practices when designing a printed circuit board (PCB) containing the
MultiConnect PCIe. Noise suppression is essential to the proper operation and performance of the modem and surrounding equipment.
Any OEM board design that contains the MultiConnect PCIe must consider both on-board and off-board generated noise that can affect digital signal processing. Both on-board and off-board generated noise that is coupled onboard can affect interface signal levels and quality. Noise in frequency ranges that affect modem performance is of particular concern.
On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is equally important. This type of noise can affect the operation of surrounding equipment. Most local government agencies have certification requirements that must be met for use in specific environments.
Proper PC board layout (component placement, signal routing, trace thickness and geometry, and so on) 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 guide. Consult noise suppression techniques described in technical publications and journals, electronics and electrical engineering text books, and component supplier application notes.
Electromagnetic Interference
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. To minimize the contribution of device-based design to EMI, you must understand the major sources of EMI and how to reduce them to acceptable levels.
■
Keep traces carrying high frequency signals as short as possible.
■ Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for ground and power distribution.
■
Decouple power from ground with decoupling capacitors as close to the device's power pins as possible.
■ Eliminate ground loops, which are unexpected current return paths to the power source and ground.
QuickCarrier™ USB-E MT100UCC-EV3 Developer Guide
DESIGN CONSIDERATIONS
■ 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.
■
Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple power lines are similar to decoupling telephone lines.
■
Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.
■
Locate cables and connectors to avoid coupling from high frequency circuits.
■ Lay out the highest frequency signal traces next to the ground grid.
■
If using a multilayer board design, make no cuts in the ground or power planes and be sure the ground plane covers all traces.
■
Minimize the number of through-hole connections on traces carrying high frequency signals.
■
Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns are better.
■
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.
■ Distribute high frequency signals continuously on a single trace rather than several traces radiating from one point.
Electrostatic Discharge Control
Handle all electronic devices with precautions to avoid damage due to the static charge accumulation.
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 strives to follow these recommendations. Input protection circuitry is incorporated in Multi-Tech devices to minimize the effect of static buildup. Take precautions 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.

SAFETY WARNINGS
Safety Warnings
Radio Frequency (RF) Safety
Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations regarding the use of radio equipment. Follow the safety advice given below.
■ Operating your device close to other electronic equipment may cause interference if the equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.
■
Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use of radio equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow restrictions for any environment where you operate the device.
■ Do not place the antenna outdoors.
■
Switch OFF your wireless device when in an aircraft. Using portable electronic devices in an aircraft may endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction may lead to suspension or denial of cellular services to the offender, legal action, or both.
■
Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle with fuel.
■
Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.
Interference with Pacemakers and Other Medical Devices
Potential interference
Radiofrequency energy (RF) from cellular devices can interact with some electronic devices. This is electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
■
Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
■ Cause the pacemaker to deliver the pulses irregularly.
■
Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause a problem.
■ Keep the device on the opposite the side of the body from the pacemaker to add extra distance between the pacemaker and the device.
■ Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or jacket pocket directly over the pacemaker).

Note: The radio's performance may be affected at the temperature extremes. This is considered normal. The radio is designed to automatically fallback in class and reduces transmitter power to avoid damage to the radio. There is no single cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient temperature, the operating mode and the transmit power.
You may need to reduce the temperature range if airflow is limited around the cellular radio. Test and verify the temperature range if the QuickCarrier USB-E is designed into an enclosed chassis.

Kermit, you can issue AT commands to communicate with and configure your modem. The AT commands let you establish, read and modify device parameters and help you control how the device operates. This section documents basic interactions with your device, such as verifying signal strength and network registrations, sending and reading SMS text messages, and sending and receiving data.
Generally, USB modems are used as unintelligent bit pipes. In Windows, this means you create a dial-up network connection that uses the Windows IP stack to use the modem to create a PPP connection to the cellular network.
The modem is assigned an IP address from the cellular carrier. This connection provides Internet access and is the basis for TCP/IP communication for sending and receiving email, creating TCP/UDP Sockets, or putting and getting files from an FTP server.
In Linux, PPPD is used to dial the modem and create the connection to the cellular TCP/IP network. This provides
Internet access for sending and receiving email, creating TCP/UDP Sockets, or putting and getting files from an FTP server.
Before You Begin
Before you begin:
■ Power up your device and ensure it is connected to the computer that you use to issue AT commands.
■
Install terminal software that can communicate with the device, such as HyperTerminal, TerraTerm, Kermit, or Putty.
Using Command Mode and Online Data Mode
Modems have two operation modes, command and online data. When you power up the modem it is in command mode and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. They allow you to establish, read, and modify device parameters and control how the modem works. The device can also generate responses to AT commands that help determine the modem’s current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem’s default data format, which is:
■ Speed: 115,200 bps
■
Data bits: 8
■ Parity: none
■ Stop bit: 1
■
Flow control: hardware
To confirm you are communicating with the device:
■
Type AT and press Enter.
