2Safety Precautions
The following safety precautions must be observed whenever the Smart SAM2W 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 SAM2W modem :
In hospitals or places where medical equipment may be in use.
In an aircraft
Refuelling points
Explosive areas
- Restricted use of the Smart SAM2W 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 SAM2W modem receives and transmits radio frequency energy while switched on, therefore
interference can occur if the Smart SAM2W is near TVs, radios, PCs or any inadequately shielded
equipment.

3Radio Frequency Exposure - SAR
The Smart SAM2W 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 SAM2W 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.

6Functionality
6.1 General
The Smart SAM2W modem consists of an RJ45 socket for serial port and input power, an FME male
antenna connector and a SIM holder. The LED indicator, located next to the SIM holder, indicates the Smart
SAM2W operating status.
FME connector
The Smart SAM2W also contains the power assist circuitry. This PA circuitry is optionally loaded and
activated when the power supply does not have enough power to assist the Smart SAM2W when it is in a
CSD call or in a GPRS session. It also helps to send the last-gasp message back to the server when power
is cut off to the modem.

8The AMR TCP/IP STACK
8.1 Descriptions
The AMR TCP/IP stack allows the Smart SAM2W modem to make/receive GSM data call and at the same
time enables the modem to act as a GPRS TCP server/client and UDP server/client. When powered up this
stack will automatically activate a GPSR connection then create 3 sockets; one TCP port in server mode for
data transfer, TCP port 11111 for remote AT Command and one UDP port for data transfer. The modem can
also create a TCP client to a remote TCP server if it is programmed to do so:
Server 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 GSM data communication.
Idle connection is disconnected after 5 minutes.
TCP Command: Socket (port 11111) connection allows a user from the host computer to send AT command
to the modem and receive its response. Idle connection is disconnected after 5 minutes.
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 GSM data communication.
In server mode modem switches serial port from data mode to AT Command mode if there
is no data from remote for 2 minutes.
Client 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 GSM data communication.
Connection is permanent.
The software stack also allows remote sending of AT Commands over SMS and GSM data call. Firmware
download over the air can be done over GSM data call using 1K XModem protocol or over GPRS using File
Transfer Protocol.
GPRS connectivity is maintained by meaning of sending Ping. The modem is also set to reset daily at 11 pm
(time feature needs support from GSM/GPRS network provider).
The modem keeps a 250 event log in a cyclical buffer which is stored in flash memory. The events log can
be retrieved by means of an AT Command either locally or remotely
