provides GSM, GPRS, UMTS and HSPA+ connectivity.
The Smart SAM3S is designed for both mobile and fixed M2M applications. It has an RJ45 socket for
input voltage and the serial RS232 signals, an FME-male for antenna connection, a SIM holder and an
LED indicator.
The Smart SAM3S 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 Smart SAM3S 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 Smart SAM3S modem :
In hospitals or places where medical equipments may be in use.
In an aircraft
Refuelling points
Explosive areas
- Restricted use of the Smart SAM3S 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 Smart SAM3S modem receives and transmit radio frequency energy while switched on, therefore
interference can occur if the Smart SAM3S is near TVs, radios, PCs or any inadequately shielded
equipment.
3. Radio frequency exposure - SAR
The Smart SAM3S 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 Smart SAM3S 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. THE SAM3S TCP/IP Operation
The SAM3S has a MCU (Microcontroller) to control the 3G module PHS8-P, the SAM3S can be operating
in there different modes, defined by parameter SAMMODE:
-SAMMODE=0, modem is in dumb mode, when power on the MCU turn on the 3G module, check its
baud rate, turn on LED and release control of the 3G module to the connecting device, AT commands
can be send from serial port here after, the MCU keep monitor the 3G module Rx pin for AT$ commands
and check time in the POLLPERIOD parameter (to reset itself and the 3G module.
-SAMMODE=1, modem is in GPRS or PSD (Packet Switch Data) smart mode, the MCU is in total control
of the 3G module, on power up the software reads all parameters from flash and activates a GPSR
connection, it then creates an UDP and a TCP socket to listen for data transfer connection, opens an
UDP and a TCP socket to listen for remote AT commands connection, if programmed as TCP client it
will tries to connect to a remote TCP server, the modem then stays in GPRS online idle state waiting for
CSD call, SMS, UDP data or TCP connection, the software maintains GPRS connectivity by the mean of
IP TRACE using POLLPERIOD parameter stored in flash.
-SAMMODE=2, modem is in CSD (Circuit Switch Data) smart mode, this mode is used if SIM card is not
setup for GPRS, MCU is in total control of the 3G module, modem is always in waiting for CSD call or
SMS.
The reason for using SAMMODE=1 for PSD and SAMMODE=2 for CSD is because it is not possible to
configure the SAM3S for simultaneous operation of PSD and CSD, when the SAM3S (3G) is connected
to PSD (IP mode), the modem status is busy when one try to make a data call to it, this is the behaviour
the of the 3G network.
The modem supports DDNS, for SIM card that has dynamic public IP address the software can performs
dynamic DNS updating to a DNS server (supporting dyndns.com and noip.com).
The modem provides security for remote management by keeping a list of SMS sending mobile numbers,
a list of CSD calling numbers, a list of PSD sending IP addresses and username and password login,
password data is encrypted for remote transaction.
8.1 Communication Sockets
TCP Data: Socket connection allows transparent data to pass through from host computer to the
modem serial port and vice versa, this operation is similar to the CSD data
communication, in TCP server mode the socket will be disconnected after 5 minutes of
no data transfer.
UDP Data: Socket connection allows transparent data to pass through from host computer to the
modem serial port and vice versa, this operation is similar to the CSD data
communication, a block of data received from a remote UDP server will open a 2 minutes
window for data to be transfer from the serial port.

TCP AT Command: Socket connection allows a user from the host computer to send AT commands
to the modem and receive its responses, socket will be disconnected after 5 minutes of
no activity, and socket also can be used for remote firmware update.
UDP AT Command: Socket connection allows a user from the host computer to send AT commands
to the modem and receive its responses, and socket also can be used for remote
firmware update.
.
8.2 TCP/IP AT$ Commands
Communications parameters are stored in Flash using AT$PARAMETERS.
Parameters are defined as:
APN=Access Point Name
USERNAME=Username that may required with GPRS login
PASSWORD=Password that may required with GPRS login
LTCPPORT=Local TCP listening port
RTCPIP=Remote TCP server IP
RTCPPORT= Remote TCP server port
TCPMODE=0 or 1 (0 disable modem TCP client, 1 enable modem TCP client)
LUDPPORT=Local binding UDP port (modem listen for UDP data on this port)
RUDPIP=Remote binding UDP IP (modem only accept data from this IP)
RUDPPORT=Remote binding UDP port (modem send UDP data to this port)
POLLPERIOD=Modem use this time to send TRACE packet to check for GPRS connectivity.
SBREAKTIME=Serial port break time, modem will wait for this break in serial port transmission before
packetize the data and send.
MBREAKTIME=Modem or GSM module serial break time, use to adjust the way the modem rebuild long
IP packet from fragments of CMUX frames.
BAUDRATE=Serial port baud rate.
