1 INTRODUCTION
1.1 Description
The MLiS MLB-G1101 is a Dual Band 2G/3G wireless terminal designed for RS232/RS422/RS485
communication over TCP/IP via any readily available 2G/3G carrier network. Overall, it is more cost
and time effective to use remote solutions to combine Machine to Machine over diverse locations
without having first to establish and invest in a huge complex network.
The MLB-G1101 wireless terminal uses the DB9 Connector to provide data communication interface
and the DC jack to provide power input. LEDs are used to indicate the status of the wireless terminal.
The MLB-G1101 wireless terminal can be used to provide a wireless communication link to many
applications, including metering, fleet and asset management, vending, security and alarm monitoring,
e-maintenance and other telemetry applications.

Figure 1: Functional Block Diagram for MLB-G1101
The MLB-G1101 consists of a fully certified (CE /NCC approved) GSM/GPRS engine, SIM card holder
and power regulator.
The wireless terminal is supplied with power via the DC jack. The remaining DB9 connector is 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-G1101 performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI
and ITU-T. The services and functions of the MLB-G1101 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. multi-slot 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 multi-slot 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.
