2 General information
2.1 How to use this document
The target audiences for this document are all categories of software and hardware
developers, system integrators and expert end-users of SIEMENS GSM wireless modules.
The content applies in particular to current users and developers whose applications are
utilizing SIEMENS MC35 for their communications purposes.
The aim of this document is to provide information and offer support in order to facilitate the
transition towards a new generation of SIEMENS wireless modules, MC35i in this case.
Information provided here is based on official technical manuals and released specifications
for MC35 and MC35i. The naming conventions used in this document follow those of source
documentation.
The authors presume the readers are already familiar with the contents of those manuals.
The document presents migration issues in detail using comparison tables between the
modules and covers topics ranging from hardware specifications to AT-command interface.
Technical specifications and interfaces to GSM telecom services are described and
compared in detail as well as all the relevant features. AT-command interface was given
particular attention since it represents the main tool available to developers through which
applications can be controlled. Available commands for both MC35 and MC35i are listed and
classified according to their implementation within each of the modules. Differences in test,
query and execution syntax as well as in available parameters are noted for each command.
Commands are classified in three main groups: jointly supported commands, MC35i
commands that are new with respect to MC35 and MC35i commands not supported by
MC35.

4 Hardware migration
This chapter contains information about the hardware design, installation instructions as well
as physical properties for both modules. Hardware features are listed in comparison tables
related to power supply, RF, audio, SIM and serial interfaces with functionality descriptions.
All features, except RF, are available through common host application interface.
4.1 Introduction
MC35i incorporates almost all of the MC35 features like EGSM 900MHz, DCS 1800MHz and
fast GPRS technology with following additional features:
æ Autobauding up to 230kBaud
æ Single side mounted
æ Two additional Sleep Modes
MC35i is super-slim, single-side mounted, compact, dual-band GSM/GPRS OEM module for
integration into industrial or mobile devices. Designed to easily provide radio connection for
voice and data transmission it integrates seamlessly with a wide range of GSM/GPRS
application platforms and is ideally suited to design and set up innovative cellular solutions
with minimum effort.
MC35i and MC35 are supporting GPRS multi-slot class 8 (4 Rx, 1 Tx time-slot) and the
GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. Modules operate in GSM 900MHz and
GSM 1800MHz frequency bands.

4.2 Operating modes
The operating modes for MC35 and MC35i modules are listed in the table below.
The MC35i module supports two additional sleep modes compared to MC35. For
further details please consult the MC35i manual.
The table below shows operating modes overview for both devices.
Table 3: Operating modes
Mode Function MC35 MC35i
GSM / GPRS
SLEEP
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 two CYCLIC
SLEEP modes AT+CFUN=5 or 6 alternate
activating and deactivating the AT
interface to allow permanent access to all
AT commands.
Software is active to a minimum extent. If the
module was registered to a GSM network in
IDLE mode, it remains, in SLEEP mode,
registered and pageable from the BTS.
Power saving can be chosen at different
levels. The NON_CYCLIC SLEEP mode
(AT+CFUN=0) disables the AT interface. The
CYCLIC SLEEP mode AT+CFUN=5, 6, 7
and 8 alternatingly activate and deactivate
the AT interface 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.
GSM TALK Connection between two subscribers is in progress. Power consumption depends on network
coverage individual settings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna.
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).
Normal
operation
GPRS DATA GPRS data transfer in progress. Power consumption depends on network settings (e.g.
power control level), uplink / downlink data rates and GPRS configuration (e.g. used
multislot settings).
POWER
DOWN
Operating voltage is applied. Only a voltage regulator in the Power Supply ASIC is active for
powering the RTC. Software is not active. The serial interface is not accessible.
Alarm mode Restricted operation launched by RTC alert function while the module is in Power Down
mode. Module will not be registered to GSM network. Limited number of AT commands is
accessible. If application is battery powered: No charging functionality in Alarm mode
(MC35 only)
Charge-only
mode
Limited operation for battery powered
applications. Enables charging while engine
is detached from GSM network. Limited
number of AT commands is accessible.
There are several ways to launch Charge-
only mode:
æ From Power Down mode: Connect
charger to POWER lines when engine was
powered down by AT^SMSO.
æ From Normal mode: Connect charger
to POWER lines, then enter AT^SMSO
Not supported
Charge mode
during normal
operation
Normal operation (SLEEP, IDLE, TALK, GPRS
IDLE, GPRS, DATA) and charging running in
parallel. Charge mode changes to Charge-
only mode when the module is powered
down before charging has been completed.
