1.3 Functional Block diagram
Figure 1: Functional Block Diagram for MLB-G3002
The MLB-G3002 consists of a fully certified (CE approved) GSM/GPRS engine, SIM card holder and
power regulator.
The terminal is supplied with power via the RJ45 connector. The remaining RJ45 connector pins are
used for data communications.
The SMA female connector provides the air interface to an external 50 ohm antenna specified for the
correct frequency band.

MLB-G3002 Terminal User Guide 10 Rev 1.1
1.4 Main Features and Services
The MLB-G3002 performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI
and ITU-T. The services and functions of the MLB-G3002 are implemented by issuing customized
applications embedded on the device, or by AT commands issued internally, or over the RJ45 to
RS232 serial interface.
1.4.1 Operating Modes
The table below briefly summarizes the various operating modes referred to in the following chapters.
Normal
operation
GSM / GPRS
SLEEP
Various power save modes set with AT+CFUN command. Software is
active to minimum extent. If the module was registered to the GSM
network in IDLE mode, it is registered and paging with the BTS in
SLEEP mode, too. Power saving can be chosen at different levels: The
NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface.
The CYCLIC SLEEP modes AT+CFUN=7 and 9 alternately activate
and deactivate the AT interfaces to allow permanent access to all AT
commands.
GSM IDLE
Software is active. Once registered to the GSM network, paging with
BTS is carried out. The module is ready to send and receive.
GPRS IDLE
Module is ready for GPRS data transfer, but no data is currently sent
or received. Power consumption depends on network settings and
GPRS configuration (e.g. multislot settings).
GPRS DATA
GPRS data transfer in progress. Power consumption depends on
network settings (e.g. power control level), uplink / downlink data rates,
GPRS configuration (e.g. used multislot settings) and reduction of
maximum output power.
POWER
DOWN
Normal shutdown after sending the AT^SMSO command. Only a voltage regulator is
active for powering the RTC. Software is not active. Interfaces are not accessible.
Operating voltage (connected to BATT+) remains applied.
Airplane
mode
Airplane mode shuts down the radio part of the module, causes the module to log off
from the GSM/GPRS network and disables all AT commands whose execution requires
a radio connection. Airplane mode can be controlled by using the AT commands
AT^SCFG and AT+CALA:
• With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured to enter
the Airplane mode each time when switched on or reset.
• The parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth
between Normal mode and Airplane mode any time during operation.
• Setting an alarm time with AT+CALA followed by AT^SMSO wakes the module up into
Airplane mode at the scheduled time.

3.2 Radio Interface (Type SMA Connector Female) - RF Antenna
Figure 4: Antenna Connector for MLB-G3002
The connection of the antenna or other equipment must be decoupled from DC voltage.
For optimum RF performance, the MLiS Terminal has to be connected to an external RF antenna
matched to 50ohms including other connecting cables across the operating frequency bands. Please use
a SMA Male connection for the terminal.
Choose suitable types of low attenuation coaxial cables if possible. In general the ohm types RG174 or
RG58 50 can be used. Avoid excessive cable length of > 10 meters.
＊Compatible RF antennas (PCB patched or Monopole type) are available for order, please
refer to accessories document.

MLB-G3002 Terminal User Guide 16 Rev 1.1
3.3 RJ45 Connector
The RJ45 Modular COM port is used to supply power to the terminal as well as provide serial data
communication. The terminal accepts voltage levels between +5Vdc to +32Vdc. Do not exceed these
levels. The minimum requirement, for the terminal to communicate with the application or DTE, is
established through using the following pins:
TxD: Where the Application sends data to MLiS Terminal
RxD: Where the Application receives data from MLiS Terminal

The MLB-G3002 Terminal is provided with a SIM card reader designed for 1.8V and 3V SIM cards. It is
the flip-up type which can be locked. It can be accessed through removing the battery cover as shown
below.

＊Be sure to power off the modem when you replace the SIM card. Otherwise it may cause
damage to the equipment.
The MLB-G3002 fully operates when inserting a SIM card. Some MLB-G3002 functionality may be lost
if you try to operate the terminal without a SIM card

4 OPERATING MODES
4.1 Power on the Modem
The modem is usually fully operational within 4 seconds, after powering it up. Depending on
the signal strength of the network in the area, logging into a network may take longer and is
outside the control of the modem.
4.2 Power off the Modem
There are 2 ways to switch off (power down) the modem as described below:
a) The “AT^SMSO” command lets the MLB-G3002 terminal log off from the network and allows
the software to enter into a secure state and safe data before disconnecting the power supply.
The mode is referred to Power-down mode. In this mode only the RTC stays active.
Make sure that the terminal has completely shut down before disconnecting the power supply.
The URC “^SHUTDOWN” indicates that data have been stored non-volatile and the terminal
turns off in less than 1 second.
b) Direct hardware power off. Data will not be retained in this case.
