2 Safety Precautions
The following safety precautions must be observed whenever the Smart SAM3T 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 SAM3T modem :
In hospitals or places where medical equipments may be in use.
In an aircraft
Refuelling points
Explosive areas
- Restricted use of the Smart SAM3T 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 SAM3T modem receives and transmit radio frequency energy while switched on, therefore
interference can occur if the Smart SAM3T is near TVs, radios, PCs or any inadequately shielded
equipments.

3 Radio Frequency Exposure - SAR
The Smart SAM3T 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 SAM3T 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 Smart SAM3T TCP/IP Operation
The Smart SAM3T has a MCU (Microcontroller) to control the 3G module HE910, the Smart SAM3T 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 Smart SAM3T for simultaneous operation of PSD and CSD, when the Smart SAM3T (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.
7.6 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.

Notes
-In SAMMODE=0, after power on the MCU turns on the 3G module, checks its baud rate, turns on LED
before releases control of the 3G module to the connecting device, all this take between 5 to 10 seconds,
so the modem is only ready for AT commands here after.
-In SAMMODE=1, the modem take 30 to 60 seconds to connect to GPRS, modem only response to AT
commands from serial port once it is connected to GPRS or after it has failed , if it failed to connect it
will reset after 120 seconds.
-In SAMMODE=2, the MCU take about 20 seconds to set up the 3G module , the modem only response to
AT commands from serial port after setting up is finished.
-In SAMMODE 1 and 2 if the Smart SAM3T modem is powered up without a SIM card it will go into AT
command mode after 20 seconds.
-The parameter POLLPERIOD which keep the time in minute which when expired will reset the modem if
SAMMODE=0 or SAMMODE=2, if SAMMODE=1 for PSD mode the modem will use this time to send
TRACE IP packet to check for network connectivity.
-In SAMMODE=1 and 2 the modem can be reset remotely by calling the voice number.
