The equipment certifications appropriate to your device are marked on the device and the accompanying product
specific information. Where appropriate, the use of the equipment is subject to the following conditions:
CAUTION
Unauthorized modifications or changes not expressly approved by Sierra Wireless, Inc.
could void compliance with regulatory rules, and thereby your authority to use this
equipment.
WARNING (EMI) - United States FCC Information
This equipment has been tested and found to comply with the Class B limits pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in an appropriate installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communication. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
WARNING – FCC RF Exposure Guidelines
While this device is in operation, a separation distance of at least 20cm must be
maintained between the radiating antenna and the body of all persons exposed by the
transmitter to meet FCC exposure guidelines.
This transmitter is only approved to operate with an antenna not exceeding 1.5 watts
total system ERP (effective radiated power) for operations with the antenna located at
more than 20 cm from all persons. The warning label must be displayed at the base of
the antenna (if stand-alone) or attached to the final product (if the antenna is integral
with the product), clearly visible to all persons exposed to the transmitter.
For Final Product Regulatory Approvals in the USA
To use the modems in the United States of America without additional FCC certifications you
must:
1. Use an antenna providing a total system ERP (effective radiated power) not exceeding
1.5 watts for operations with the antenna located at more than 20 cm from all persons. If the
system exceeds 1.5 watts ERP then separate submissions to the FCC are required.
2. Place a warning label on the antenna (if stand-alone) or attached to the final product visible to
all persons exposed to the transmitter (if the antenna is integral with the final product). This
label must state:
Page ii Proprietary and Confidential 2110059 Rev 1.1

“WARNING:
While this device is in operation, a separation distance of at least 20cm must be
maintained between the radiating antenna and the body of all persons exposed to the
transmitter to meet FCC exposure guidelines.”
3. The word “WARNING” should be placed in front of or above the warning statement included
in documentation and also in the actual warning label on the antenna or final product.
This warning label is not required when Specific Absorption Rate (SAR) compliance of a final
product configuration is approved through a separate FCC equipment authorization approval.
Otherwise, the warning label is required on the antenna or final product in order to meet separating
distance requirements to satisfy the FCC RF exposure requirements.

Upgrading
If your modem firmware is an earlier version, you can acquire updated firmware by contacting
Sierra Wireless Technical Support at 604.231.1128 or by e-mail to support@sierrawireless.com.
Instructions for updating the modem firmware are contained in Section 3.8 Updating Modem
Firmware.
Descriptions of Watcher and WirelessExpert are current with revision R3.3.1. The revision is
reported in the splash screen when the program is started and can be checked using the Help >
About option from the program’s menu.
1.4. Document Structure
This document focuses on the operational view. The hardware view is covered in a reference
section at the end.
There is a Getting Started chapter in this section intended to help you quickly get the toolkit
components connected and communicating.
The operational view follows, starting with the basics of the Watcher and WirelessExpert
software provided with the toolkit. Important background on the modem basics, including
terminology used in this guide, starts you into the operational elements of getting your modem
configured and operating. There are separate chapters covering modem operation in each of the
three possible modes with sample configurations.
The hardware view is covered in two chapters. The first describes the modem product
descriptions including the hardware integration issues of each of the modems. The second is a
reference to the Multipurpose Interface Board (MIB) used to test and configure the modem during
product development.
1.4.1. Modem Operations
The various modes, states, and conditions the modem can be placed in are described in the chapter
on Basic Modem Operations. That chapter also discusses the communication interface between
the host (DTE) and the modem.
The types of protocols supported in each mode are described but examples of configuring the
modem will be found in the chapters on operations for each specific mode.

After completing this chapter, you should be able to communicate (DTE to DCE) with the modem
by using AT commands from a host terminal. Modem connection to a remote modem is not
covered until the Operational View.
The chapters immediately following deal with the Operational View. Software Installation will
deal with the installation on a host PC of the Watcher and WirelessExpert™ software which make
further configuration of the modem and testing on a CDPD network (if applicable) much simpler.
A reference section covering the Hardware View follows at the end of the manual.
2.2. Registration
Before you can use your modem for wireless communication you must register it with a cellular
service provider. This section describes what they will need to know and what information they
will provide to you.
Contact your service provider to get the registration process started. While the service provider is
getting your account configured, you can install and configure your modem. Record the
information provided by your carrier for configuring the modem later.
In any coverage area there can be two providers, each assigned to a “side” (A or B) of the cellular
waveband. Each provider is also assigned a Service Provider Network Identifier (SPNI) number.
2.2.1. CDPD
To use your modem in CDPD mode it must be activated on a CDPD network. To register your
modem for Wireless IP activation on CDPD networks, contact your local CDPD service provider.
Give the CDPD service provider the Equipment Identifier (EID). This is the identification
number of the radio/modem. A Sierra Wireless modem EID has the following format:
Look for this number on the back of your modem and on a label affixed to the outside of the
package that the modem was shipped in. If only the ESN (Electronic Serial Number) can be found
you can convert it to a Sierra Wireless EID by expressing the last 8 digits as hexadecimal values.
For example:
The EID number is also available by querying the modem with the AT+WPEID command.
The CDPD service provider supplies the following:
1. Modem address, commonly referred to as a Network Entity Identifier (NEI). This may also
be referred to as your Internet Protocol (IP) address. This identifies your modem on a CDPD
network and on the Internet.
2. IP address of a router or server to ping when testing the connection. This may be a Domain
Name Server (DNS).
00-A0-D5-xx-xx-xx
ESN: 206 - 00057628 = EID: 00-A0-D5-00-E1-1C
57628 = 0xE11C
2110059 Rev 1.1 Proprietary and Confidential Page 5
SB300 Series User’s Guide
Both of the above items are in the form of an IP number. This is made up of four numbers
ranging in value from 0 to 255, separated with periods (sample: 192.168.0.9)
3. Side designator, A or B. This is determines the channels used by your CDPD service
provider.
4. SPNI number of the provider. This is optional. The Service Provider Network Identifier
(SPNI) can be used to restrict the modem to accepting service from a limited list of providers
and can help speed up cellular channel acquisition and registration.
This information will be required when configuring your modem for CDPD registration either
with WirelessExpert or AT commands.
2.2.2. CSC (AMPS)
To use your SB320 modem in CSC mode it must be activated with a cellular phone service
provider. To register your modem for CSC activation, contact your local cellular carrier.
Give the service provider the Electronic Serial Number (ESN). This is the identification number
of the radio/modem. A Sierra Wireless ESN has the following format: 206-xxxxxxxx. Look for
this number on the back of your modem and on a label affixed to the outside of the package that
the modem was shipped in. The number is also available by querying the modem with the
AT+WVESN command.
The cellular service provider supplies the following:
1. A Number Assignment Module (NAM). This is your cellular telephone number and your
Home System ID (SID).
2. Side designator, A or B. This determines the channels used by your service provider.
This information will be required when configuring your modem for CSC mode use either with
WirelessExpert or AT commands.
2.2.3. Wireline
There are no particular setup issues to configure your SB320 modem for use in wireline mode. It
is required that the telephone line be analogue - not digital as found on some PBX systems.
2.3. Setup Considerations
2.3.1. Host Computer Terminal
You will require a PC with a communications program capable of operating in ASCII terminal
emulation mode. This allows the PC to function as a terminal attached to the modem and permits
the entering of AT commands required for modem setup and diagnostics. We recommend that the
program chosen be capable of logging terminal communications activity to a file for later analysis
or printout in the event that technical support is required.
For IBM PC-compatibles, Windows Terminal, Hyperterminal, Procomm, and Kermit are all
acceptable. Note that early versions of Hyperterminal do not allow you to send SLIP framing
characters to the modem, preventing use of the escape sequence. This is corrected in later
versions.
A 9-pin D connector RS-232 serial cable (part number 006.0011) is provided with the OEM
Developer’s Kit for connecting the PC host to the Multipurpose Interface Board.
Page 6 Proprietary and Confidential 2110059 Rev 1.1
Getting Started
2.3.2. Physical considerations
NOTE
The MIB and modem can be sensitive to static so the work surface should be a
static controlled environment.
2.3.3. Antenna considerations
The SB300 Series modem uses standard mobile cellular radio signals. An antenna (part
number 1810009) is provided with the OEM Developer’s Kit. Along with this antenna is a
connector adapter (part number 2000066) to convert the antenna connector (Male SMA) to match
the modem requirement (Male MMCX).
You can use an antenna of your own if you choose. Any standard cellular antenna of good quality
will function properly provided you have a suitable connector.
CAUTION
The combination of cable loss and antenna gain must yield an overall system gain not
exceeding 0 dB. The transmitter output of 0.6 Watt is delivered at the connector. This
is the FCC regulated limit of a Class I device.
Antenna performance is subject to the following guidelines:
Location – Locate the antenna as far away from personnel as possible to minimize signal
blocking. For optimum reception in indoor fixed location applications, position the antenna above
the height of personnel and nearby equipment or structures. Locate the antenna as close to a
window as possible.
Cabling – Select a low loss, high quality, 50-ohm, coaxial cable with the appropriate connectors.
The cable can be any length, but lengths greater than 4 metres (13.1 feet) increase cable loss and
offset the antenna’s nominal gain. If longer length cables are required, use a heavier wire gauge to
reduce the dB loss/m and to minimize the effect of the cable loss on antenna gain.
Ground Plane – For installations where a good antenna ground plane (metal surface) is not
available, use a non-ground plane type of antenna to help maximize signal reception.
Proximity to Other Antennas – In general, do not locate the SB300 Series modem antenna closer
than 1.5 metres (5 feet) to another antenna. In certain cases even more separation is required. The
effect of the interference from two-way transmitters varies from slowing down response times to
blocking modem transmission.
The SB300 has recently had hardware modifications to support an upcoming Sierra Wireless
3-Watt booster.
CAUTION
In cases where the antenna output is to be connected to test equipment, DC blocks must
be used on the antenna output to protect the test equipment and avoid false booster
detection..

2.4. MIB Presets
The Multipurpose Interface Board has several switches and jumpers which should be configured
as follows for the initial setup.
• DIP Switch in the Serial Breakout Box:
Switches 1 through 8 should be closed (on)
Switches 9 and 10 open (off).
• Power Select (J21) should be on pins 1 – 2 (+5V).
• HOSTSHDN, \SHDN, and MODEM DIS jumpers on J24 should all be off.
• Speaker Enable should be on.
2.5. Connections
This section describes the steps to connect the PC host, MIB, and modem. At the end of this
procedure you should be ready to configure and use the modem. If results at any step are not as
described, consult the chapter on troubleshooting.
To connect follow these steps:
1. Attach the RS-232 serial cable from the host to the MIB PC Serial Port connector (J1).
The Serial Breakout Box indicators for DTR, TxD, and RTS should all light (powered from
the RS-232 connection).
2. Start the terminal application on the host PC. Configure the application for the port connected
to the MIB. At this time, the modem initially requires a setting of 19200 bps, 8 data, no
parity, 1 stop, with hardware (RTS/CTS) flow control.
3. Instruct the terminal application to connect.
The DTR and RTS indicators should be green. The TxD indicator should be red.
4. Attach the 30-pin flat flex modem connector strap to the MIB’s SB300/SB320 port.
To make the SB300/320 connection:
i. Open the hinged SB300/SB320 connector on the MIB by lifting it away from the
edge of the board.
ii. Slide the strap into the connector with the contact side down (coloured side up).
Be sure it is fully inserted.
iii. Close the connector by pressing down on the ends of the connector rather than the
centre.
iv. Connect the 13-pin I/O cable to the MIB and the modem. This connector is keyed
to prevent connection error.
Page 8 Proprietary and Confidential 2110059 Rev 1.1
Getting Started
5. Attach the modem to the connector strap using the same procedure as the MIB end of the
connector.
CAUTION
Although the MIB provides support for the full SB Series of modems, it is not intended
to support more than one modem at a time. Attaching more than one modem can
damage circuitry.
6. Place the antenna is a suitable location, attach the antenna connector adapter to the antenna
cable, and attach the cable to the modem.
7. Ensure the modem power switch is OFF.
8. Plug the 12V DC power adapter into a 120V AC outlet and connect the power supply to the
MIB.
9. Switch on the MIB and modem power using the POWER switch on the MIB.
The remaining LED indicators should come on. Power indicators for 7V and 5V should show
red. The Serial Breakout Box indicators should all light; the DSR signal shows green. The
Status indicators should begin operation to specification as the modem initializes. In about 6
to 10 seconds (following the modem’s internal initialization) the CTS serial signal should go
green and OK should appear on the PC terminal.
10. Type AT<enter> at the host terminal. The modem should reply with OK.
The modem is now ready to be used with the host computer.
You may now continue to use the modem with the terminal application, or you may close the
terminal application and use Watcher and WirelessExpert (described below) to configure and use
the modem.

3. Software Installation
3.1. Introduction
This chapter provides instructions for installing Watcher and WirelessExpert™ on a host PC and
using these programs to configure and use the modem. It also includes procedures for updating
the firmware on the modem if needed.
NOTE
Running WirelessExpert is required before using Watcher. WirelessExpert will install
and configure necessary drivers on the host PC.
Watcher
Watcher is a Windows application that configures and monitors Sierra Wireless modems for
CDPD, Circuit Switched Cellular (CSC), and Wireline operation. This chapter explains how to
install Watcher and describes basic Watcher operations and important screen elements.
WirelessExpert
Installation of the drivers required for modem operations is performed with an installation wizard
called WirelessExpert. This can be run at any time to view and edit the cellular activation settings
(NAMs, NEIs, etc.). It allows you to test cellular connections.
3.2. Installing Software on the Host
The software is provided on CD-ROM. The CD is self-starting when inserted into a PC running
Windows 95/98/NT. An installation wizard will guide you through the process.
A menu folder is added to the Start > Programs menu:
2110059 Rev 1.1 Proprietary and Confidential Page 11
The Operational View SB300 Series
3.3. Configuration using WirelessExpert
WirelessExpert will automatically locate the modem on a COM port, interrogate it for features,
and install the required drivers on your host PC. It will then allow you to set or alter the cellular
activation settings.
To make the modem drivers available to the Windows operating system, the PC may be restarted
part way through the execution of WirelessExpert. This is done automatically but does require
that no other programs are running on the PC at the time.
Preparation:
1. Ensure the host serial connection to the modem via the MIB is in place and the modem power
is on. The full set of serial communication LED indicators should be on.
2. For CDPD configurations:
a. Ensure the modem is in CDPD mode (+WS46=4). This can be queried (AT+WS46?) to
verify.
b. Ensure the modem is using the SLIP mode of service (+WS45=3). This can be queried
(AT+WS45?) to verify.
c. Ensure the modem is set to auto-register (+WS173=1).
3. Close any open applications on the host PC including any communication program connected
to the modem. A system restart supervised by WirelessExpert may fail if other programs are
running. Leave the modem on.
4. Have the NAM / NEI and related information from your cellular service provider ready. See
Section 2.2 for information on cellular service registration.
Installation:
1. Select Start > Programs > Watcher > WirelessExpert from the Windows taskbar.
2. Select the modem being used from the list:
SB320 – OR – SB300 Series for the SB300
3. Click Next > and then Next > again to skip the page regarding setup of other modem
products. WirelessExpert then locates the COM port connected to the modem and finds the
related registry entries for it. The results are displayed.
4. Click Next > to have WirelessExpert install the appropriate drivers for the modem.
5. A message may appear advising of the need to restart the computer. Click OK.
WirelessExpert shuts down the computer and restarts it for you.
6. When the setup wizard reappears, continue to click Next > until you pass the section on
connectivity components. WirelessExpert now examines the modem for cellular network
activation, reading any NAM and NEI entries stored on the modem.
7. The next page allows you to set the level of access to configuration settings that will be
allowed to the Watcher program. Setting “full access” will allow Watcher to alter the NAM /
NEI settings, “read-only” will allow Watcher to display the settings but you will have to use
WirelessExpert or direct AT commands to alter settings.
8. For SB320 installations, the NAM entries for CSC activation will be presented for entry and
editing. This screen is automatically skipped for CDPD only modems.
9. For SB320 installations, WirelessExpert can test the connection provided you have a
registered NAM and a number to dial. This tests that the modem can obtain a cellular channel
and place a call. The called station can be your own voice line if you simply want to verify
that the modem can reach a destination phone number. The test can be skipped by marking
the checkbox on the screen. This test screen is automatically skipped for CDPD only
modems.
10. The CDPD settings of the modem are displayed for entry and editing. A radio button sets the
active NEI for use. A pull-down menu allows setting of the channel side preference.
Page 12 Proprietary and Confidential 2110059 Rev 1.1
User’s Guide Watcher and WirelessExpert
11. You are prompted to enter an IP address for a Domain Name Server (DNS). Your cellular
service provider should have provided one. This address is used for testing the CDPD
configuration by “pinging” the provided address. It is also added to the Windows Dial-up
Networking profile. The DNS is not stored in the modem, it is on the host side only.
12. The CDPD settings can now be tested by WirelessExpert and will be setup in the Windows
Dial-up Networking Connection facility. A pull-down menu allows you to select the NEI to
use for the local end of the test. If you select one different from the radio button selection on
the previous screen, the new setting will become the default. This test will verify that you can
register with the CDPD network and will “ping” the DNS server to verify the connection.
The test can be skipped if desired.
13. Click Finish to complete the WirelessExpert configuration. The modem should now be ready
for use.
WirelessExpert will have created an entry in Windows Dial-up Networking for CDPD mode. You
may notice that it is configured to dial the number 2. This is normal. Although CDPD
connections do not actually dial a number, Windows Dial-up Networking requires that a telephone
number be entered.
3.4. About Watcher
Watcher is a configuration and monitoring tool to manage Sierra Wireless modems. The program
can set the modem mode of operation (CDPD, CSC, or Wireline) and can be used to get
information about cellular connections and signals. Watcher can also monitor modem connection
when using CDPD mode.
WirelessExpert must be run initially to properly install and register the required connectivity
components with Windows. If you have not run WirelessExpert on the host PC to be used with
the modem it must be done before using Watcher.
3.5. Using Watcher for Modem Setup
When Watcher is started, it will check a registry on the PC to see what mode the modem was last
used in. If it was CDPD then the program will open a CDPD connection using the settings in the
Dial-up Networking facility of Windows which were configured by WirelessExpert. If an SB320
was last used in either CSC or Wireline mode then Watcher will attempt to set the modem to that
mode.
To start Watcher:
Select Start > Programs > Watcher > Watcher from the Windows taskbar.
Watcher will locate and initialize the modem. It will then indicate the mode and condition of the
connection.
3.5.1. Configuring Watcher

3.8. Updating Modem Firmware
Should your modem(s) require a firmware upgrade, this section describes the procedure.
See Section 1.3 Currency for information on the current revisions at the time of this writing. That
section also describes the method to determine the firmware revision on the modem.
You can acquire updated firmware by contacting Sierra Wireless Technical Support at
604.231.1128 or by e-mail to support@sierrawireless.com. In most cases you will be provided a
URL to download the update over the Internet. You may have the option to use a ZIP file
(requiring either PKUNZIP ver 2.04g or WINZIP v5.6) or a slightly larger self-extracting
executable file. Both of the ZIP utilities are available from links on the Sierra Wireless download
page.
To download the update:
1. Create a folder on your PC in which to store the download.
2. Enter the URL provided for the chosen download and save the file in the folder you have
created.
3. If the ZIP file was downloaded then Unzip it using your extraction utility.
Before updating make sure you know which COM port your modem is connected to. This
information is required by the upgrade utility.
To upgrade the Modem firmware, you can run either:
• SETUP.EXE program in Windows,
– or –
• INSTALL.BAT command file from DOS.
DOS firmware upgrade:
1. If you run the DOS option , EXIT Windows completely.
2. Change Directory to the one with the downloaded firmware.
3. Turn off the modem.
4. Enter INSTALL <space> d where d is the COM Port number.
Examples: INSTALL 1 (installs the firmware using COM 1)
INSTALL 3 (installs the firmware using COM 3)
5. Follow the Install instructions carefully.
Windows firmware upgrade:
1. Close all open applications.
2. Turn off the modem.
3. Run either the self extracting update file (which will expand and execute in one step) or the
SETUP.EXE file.
4. Select the COM port your modem is connected to.
5. You will be prompted to turn on the modem. When you have done so, the installation
program will automatically perform the balance of the update.
Installation provides “thermometers” indicating the progress of the update. These are only a
guideline. Do not be surprised if the update completes before the indicators have been updated.
After the upgrade is complete you may delete the download folder or retain it for updating
additional modems, as you choose.
