1.3 Functional Block diagram
Figure 1: Functional Block Diagram for MLB-S-BGS2-BW
The MLB-S-BGS2-BW consists of a fully certified (CE approved) GSM/GPRS engine, SIM card holder
and power regulator. The status of the terminal is indicated via an LED.
Power is supplied to the terminal 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.
1.4 Main Features and Services
The MLB-S-BGS2-BW perform a set of telecom services (TS) according to GSM standard phase 2+,
ETSI and ITU-T. The services and functions of the MLB-S-BGS2-BW are implemented by issuing
customized applications embedded on the device, or by AT commands issued internally, or over the
RJ45 to RS232 serial interface.

MLB-S-BGS2-BW Terminal User Guide 10 Rev 1.3
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 alternatingly 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-S-BGS2-BW
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 to the terminal.
Choose suitable types of low attenuation coaxial cables if possible. In general the RG174 or RG58 50
ohms types should be good for normal use. Avoid excessive cable length of > 10 metres.
＊Compatible RF antennas (PCB patched or Monopole type) are available for order, please
refer to accessories document.
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 through
using the following pins:
TxD: Where the Application sends data to MLiS Terminal
RxD: Where the Application receives data from MLiS Terminal

3.4 Operating States/LED
The modem has a green and a blue LED to display the operating status of the Terminal. The green
LED is power indicator,Blue is operating Status LED.
Figure 6: LEDs for MLB-S-BGS2-BW

MLB-S-BGS2-BW Terminal User Guide 17 Rev 1.3
3.4.1 Blue LED
The AT^SSYNC command is used to control the Green LED status on the terminal.
Mode
LED Status
AT^SSYNC=0
SYNC mode:
Enables the SYNC pin to indicate growing power consumption during a transmit
burst. You can make use of the signal generated by the SYNC pin, if power
consumption is your concern. To do so, ensure that your application is capable
of processing the signal. Your platform design must be such that the incoming
signal causes other components to draw less current. In short, this allows your
application to accommodate current drain and thus, supply sufficient current to
the GSM engine if required.
AT^SSYNC=1
LED mode:
Enables the SYNC pin to drive a status LED installed in your application.
Note: <mode>=1 is the factory default of the MLB-S-BGS2 Series Terminal.
Table 6: AT Command for Blue LED Control for MLB-S-BGS2-BW
The following table lists the possible patterns of status LED behavior, and describes the terminal
operating status indicated by each pattern if AT^SSYNC parameter <mode>=1. To better monitor the
operating states while power saving is enabled.

3.5 SIM card holder
The MLB-S-BGS2-BW Terminal is fitted 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.
Figure 7: SIM Card Holder for MLB-S-BGS2-BW
＊Be sure to power off modem when you replace the SIM card. Otherwise it may cause damage
to the equipment.
The full operation of the MLB-S-BGS2 Series relies on a SIM card being inserted. Some MLB-S-BGS2-
BW functionality may be lost if you try to operate the terminal without a SIM card

4 OPERATING MODES
Figure 8: LED indication for MLB-S-BGS2-BW
4.1 Power on the Modem
The modem is usually fully operational 4 seconds after power up. Depending on the signal
strength of the network in the area, logging onto a network may take longer and is outside the
control of the modem.
A blinking Blue LED indicates normal operation.
4.2 Power down the Modem
There are 2 ways to switch off (power down) the modem as described below:
a) The “AT^SMSO”command lets the MLB-S-BGS2-BW 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.
