1. Introduction

The SAM3G+ is a compact, light-weight, UMTS, HSPA based modem. It provides GSM, GPRS,
EDGE and WCDMA connectivity. The SAM3G+ is a quad-band GSM/GPRS/EDGE 850MHz,
900MHz, 1800MHz, 1900MHz and a quad-band WCDMA/HSDPA : 850MHz, 900MHz,1900MHz,
2100MHz

The SAM3G+ is designed for both mobile and fixed M2M applications. It has an RJ45 socket for
both input voltage and serial RS232 signals, a MiniB USB connector, a SMB-Jack for antenna
connection, a SIM holder and an LED indicator.

The SAM3G+ is capable of sending/receiving SMS, Circuit switched data and Packet-switched
data.

2. Safety Precautions

The following safety precautions must be observed whenever the SAM3G+ modem is in
operation or in service. Failure to comply with these precautions violates the safety standards of
the design, manufacture and intended use of the product

- Switch off the SAM3G+ modem :
In hospitals or places where medical equipments may be in use.

In an aircraft
Refueling points
Explosive areas

- Restricted use of the SAM3G+ modem
Near any chemical plant

Near any Fuel depot
Areas with mobile phone warning signs

Respect national regulations on the use of cellular devices. Road safety always comes first
The SAM3G+ modem receives and transmit radio frequency energy while switched on,

therefore interference can occur if the SAM3G+ is near TVs, radios, PCs or any inadequately
shielded equipments.

3. Radio frequency exposure - SAR

The SAM3G+ modem is a low-power transceiver, similar to a typical handheld
GSM/GPRS/UMTS mobile phone. When it is turned on, it will emit low-level radio frequency
energy.

There are different guidelines and standards around the world that govern the permitted levels of
radio frequency exposure for general population. The levels include a safety margin to a human
body.

The Specific Absorption rate (SAR) is a measure of the rate at which radio frequency energy is
absorbed by the body when exposed to radio frequency electromagnetic field. The SAR value is
determined at the highest certified power level in the laboratory conditions, but the actual SAR
level of the transceiver while operating can be well below this value. This is because the
transceiver is designed to use minimum power to connect to the network.

The SAM3G+ modem is approved to use in applications where the antenna is placed more

than 21cm from the body.

For other applications, the integrator is responsible for the local SAR requirements.

8. Operation

The SAM3G+ can support either the USB port or the Serial RS232 port. The port
configuration is done at the point of sale. Do not operate these 2 ports at the same time !

8.1 Using the USB port

a. Installing the USB driver

Note : If the old driver version has been installed, it must be removed, before installing the latest

driver. To uninstall the old driver, follow these steps :

- Open the Control Panel

- Double click System, System Properties window appears

- Select the Hardware tab

- Select the Device Manager

- Expand the Universal Serial Bus controllers to show the installed devices.

- Right click the Sierra Wireless MC87xx device entry and choose Uninstall.

- Click OK to confirm.

Step1 : Locate and run the DriverInstaller.exe . Note that there is no feedback, just wait a few
moments for the program to run.

Step2 : Connect the SAM3G+ to the PC, using the supplied USB cable. Several Found New
Hardware balloons appear above the tool tray as the system detects the new devices. After the

devices are detected, the Device Manager will show, in the following categories :

- Network Adapters : Sierra Wireless HSDPA Network adapter.

- Port (COM&LPT) :
Sierra Wireless AT Command port (UMTS)
Sierra Wireless CNS port (UMTS)
Sierra Wireless Data Port (UMTS)
Sierra Wireless DM Port (UMTS)

- Universal Serial Bus Controllers : Sierra Wireless MC87xx device

b. Firmware upgrade

The USB port is used for firmware upgrade. Refer to the SAM3G+FirmwareUpgrade document
for further details.

Ph : 61 3 9239 2000 Fax : [phone]

8.2 Using the Serial RS232 port

The RS232 default configuration is :

- Terminal speed : 115200bps (+IPR=115200)

- Data format : 8 data bits 1 stop bit (+ICF=3,3)

- Hardware RTS, CTS flow control (+IFC=2,2)

- No auto-answer (S0=0)

There are 6 serial data signals available at the RJ45 connector, namely DCD, DTR, RXD, TXD,
RTS and CTS. There is an option for RI (Ring Indicator) signal instead of DTR signal.

This configuration allows any external controller to communicate with the SAM3G+ at 115200bps
over the serial port. The external device can set up the SAM3G+ modem using AT commands,
can tranfer Circuit-switched data or Packet-switched data.

With packet-switched data, the external device must be capable of communicating using PPP,
TCP/IP or UDP/IP.

c. AT commands :

The SAM3G+ modem supports most of the AT commands specified in the following standards :

- 3GPP TS 27.005 : Control SMS functions for devices on GSM/WCDMA networks

- 3GPP TS27.007 : Control devices operating on GSM/WCDMA networks

- ITU-T V.250 : Control serial communications over an asynchronous interface

For details of the AT commands, refer to the “Supported AT command” and “Extended AT
commands” manuals.

Setup example : Serial port connection to a PC
