2 Safety Precautions

The following safety precautions must be observed whenever the Smart SAM2S 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 SAM2S modem :

 In hospitals or places where medical equipment may be in use.
 In an aircraft
 Refueling points
 Explosive areas

- Restricted use of the Smart SAM2S modem

 Near any chemical plant
 Near any fuel depot
 Areas with mobile phone warning signs

Respect national regulations on the use of cellular devices.

The Smart SAM2S modem receives and transmits radio frequency energy while switched on, therefore
interference can occur if the Smart SAM2S is near TVs, radios, PCs or any inadequately shielded
equipment.

3 Radio Frequency Exposure - SAR

The Smart SAM2S modem is a low-power transceiver, similar to a typical handheld GSM/GPRS 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 SAM2S 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 SAM2S TCP/IP Operation

The Smart SAM2S has a MCU (Microcontroller) to control the 2G module PHS8-P, the Smart SAM2S 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 2G module, check its baud
rate, turn on LED and release control of the 2G module to the connecting device, AT commands can be send
from serial port here after, the MCU keep monitor the 2G module Rx pin for AT$ commands and check time
in the POLLPERIOD parameter (to reset itself and the 2G module.

-SAMMODE=1, modem is in GPRS or PSD (Packet Switch Data) smart mode, the MCU is in total control of
the 2G 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 2G module, modem is always in waiting for CSD call or SMS.

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.

Smart SAM2S User Guide V1.4

Ver1.4

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.

AT$SMSTOSERIALON

This command allows the connecting device to receive SMS notification for 300s: e.g. “+CMTI: "SM",1”,

the connecting device must send AT+CMGR to read SMS and AT+CMGD to delete it, during this

300s period, modem will not able to decode AT$ commands sending to it over SMS.

8.3 CSD Call Escape Sequence

During CSD call to the Smart SAM2S modem, send three consecutive EscEscEsc or hex number
sequence 0x1B 0x1B 0x1B to switch the modem between data mode and remote AT commands mode.

Notices

-In SAMMODE=0, after power on the MCU turns on the 2G module, checks its baud rate, turns on LED
before releases control of the 2G 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 2G module , the modem only response to
AT commands from serial port after setting up is finished.

-In SAMMODE 1 and 2 if the Smart SAM2S 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.
