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

3Radio Frequency Exposure - SAR
The SAMXQ modem is a low-power transceiver, similar to a typical handheld 3G/LTE 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 SAMXQ 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.

8The SAMXQ TCP/IP Operation
The SAMXQ has an MCU (Microcontroller) to control the LTE module BG96. The SAMXQ can be operating in
three different modes, defined by the parameter SAMMODE:
-SAMMODE=0. The modem is in standard mode. When powered on, the MCU turns on the LTE module,
checks its baud rate, turns on the LED and releases control of the LTE module to the connecting device. AT
commands can be sent from the serial port here after, the MCU will keep monitoring the LTE module Rx pin
for AT$ commands and checks time in the RESETPERIOD parameter to reset itself and the LTE module.
-SAMMODE=1. The modem is in PSD (Packet Switch Data) smart mode. The MCU is in total control of the
LTE module. When powered on the software reads all parameters from flash and activates a PSD connection,
it then creates a UDP and a TCP socket to listen for data transfer connection, opens a UDP and a TCP socket
to listen for remote AT commands connection. If programmed as a TCP client it will try to connect to a remote
TCP server, the modem then stays in PSD online idle state waiting for SMS, UDP or TCP connection. The
software maintains PSD connectivity by means of PING using POLLPERIOD parameter stored in flash.
8.1 Communication Sockets
TCP Data: The socket connection allows transparent data (excluded IP header) to pass through from the
remote host to the modem serial port and vice versa. In TCP server mode, the socket will be
disconnected after 5 minutes of no data transfer.
UDP Data: The socket connection allows transparent data to pass through from the remote host to the
modem serial port and vice versa. A block of data received from a remote UDP server will
open a 2 minutes window for data to be transferred from the serial port.
TCP AT Command: The socket connection allows a user from the host computer to send AT commands to the
modem and receive its responses. The socket will be disconnected after 5 minutes of no
activity. The socket can also be used for remote firmware update.
UDP AT Command: The socket connection allows a user from the host computer to send AT commands to
the modem and receive its responses. The socket can also be used for remote firmware
update.

modem DCD pin goes high, data from serial will be packetized into UDP packets and sent to remote UDP
server (UDP settings must be set prior), modem will return to AT Command mode if it receives no UDP data
in 30 seconds.
