Safety information
Radio devices have limitations in the vicinity
of electronic devices:
• Switch the Terminal off when you are in a
hospital or near medical devices like
pacemakers or hearing aids. The Terminal
may interfere with the operation of these
devices.
• Switch the Terminal off when flying.
Secure it so that it cannot be switched on
inadvertently.
• Switch the Terminal off when you are near
petrol stations, fuel depots, chemical
plants or blasting operations. The
Terminal can disturb the operation of
technical equipment.
• Interference can occur if the device is
used near televisions, radios or PCs.
• In order to avoid possible damage, we
recommend that you only use the
specified accessories. These have been
tested and shown to work well with the
Terminal. However, the warranty does not
cover these accessories.
The warranty does not apply in the event
of improper use.

Product description
The ES75 modem is a compact GSM/GPRS/
EDGE modem for the transfer of data,
SMS and faxes in GSM networks. The ES75
modem supports the EDGE standard and
thus permits a far higher data transmission
rate up to 384 kbps. Packet-oriented data
transmission and a permanent online
connection enable rapid data access and
transmission rates. Industrial standard
interfaces and an integrated SIM card
reader mean it can be used rapidly, easily
and universally as a quad band GSM/GPRS
modem. Its performance band width and
the robust housing make it easier to quickly
implement new applications in areas such
as telemetry and telematics.
The features, functions and interfaces of the
modem ES75 are described below.
The functionality of the modem corresponds
to the features of the MC75 module, to
which a SIM card reader, an RS232
interface, an mini USB interface and a
greater supply voltage range have been
added.
All the external interfaces of the modem are
integrated permanently in the housing. The
plug-in connections are standardised and
suitable for use under vibration.

Polarity reversal protection is implemented
by means of a power diode. The diode has a
reverse voltage of 400 V.
Overvoltage protection
Overvoltages are suppressed by a Zener
diode after the polarity reversal protection
diode.
Fuses
A permanently installed, non-replaceable
fuse in the modem ensures electrical safety
in the event of faults. Connect a fast 1.25 A
fuse to the supply line of the positive supply

Description Parameters

Startup
Before startup, the components required for
your application must be connected. The
SIM card must be inserted in a deenergized
state.
The modem is ready for operation when
supply voltage is applied and the ignition line
is activated. If the recommended plug-in
power supply unit is used, the ignition line is
already connected to the supply voltage line,
and the modem is thus immediately
switched to the active state. It starts the
network search and registers with network
operator. Please read the following
conditions for switching the modem on and
off:
Switching Simply applying supply voltage (+ to pin 1
on modem and GND to pin 6) alone is not enough to
switch on the modem.
It can be switched on in two different ways:
Activation of the IGT_IN ignition signal
on the power supply connection
The switching regulator is switched on with
the IGT_IN = high signal. When the
switching regulator is switched on, VBAT is
generated as the operating voltage for the
GSM/GPRS module. This still does not
activate the GSM/GPRS module. Triggered
by VBAT, a transistor switch generates the
IGT ignition signal with a delay of approx.
100 ms for the GSM/GPRS module. Only
then is it switched on. (It exits the POWER
DOWN operating state.)
23
Startup
In its energized state, the GSM/GPRS
module provides the supply voltage (VDD).
VDD ensures that the switching regulator
remains on, even when its closing condition
is lost (i.e. IGT_IN = low).
Explanation:
VBAT = operating voltage for the module
VDD = supply voltage from the module
Activation of the RS232 or USB control
line DTR
The modem can be switched on in the same
way as via IGT_IN by activating the RS232
control line DTR (high signal).
Note
The modem is switched on immediately
using the recommended plug-in power
supply unit (see the above explanation on
startup).
Switching off / The modem can be switched off in two
resetting the different ways:
modem Using a software command by means of
an AT command
A software shutdown via an AT command is
always advisable for a controlled shutdown
of the modem. In this case, the GSM/GPRS
module signs off before the watchdog
condition results in the specific switching off
of the supply voltages.
24
Startup
Activation of the PD_IN reset signal on
the power supply connection
The POWER DOWN line on the GSM/GPRS
module is connected to the watchdog input
pin of the power supply ASIC, which can
only be switched off by changing the
watchdog condition. To do this, the PD_IN
modem reset line is active (high) for at least
3.5 s. This results in immediate, "hard"
disconnection, with the modem unable to
sign off correctly from the base station in
the STANDBY and TALK operating states .
In the case of this hardware shutdown, the
software is no longer able to respond before
the voltage is switched off. This
corresponds to a direct, unannounced
disconnection of the operating voltage. In
the application you can switch off or reset
the module without interrupting the input
voltage supply.
25

Operating states / LED
Note:
Usually, the network search takes only a
few seconds till the modem is registered. If
the flashing continues, this means that no
SIM card is inserted, no PIN number is
entered or no GSM network is available.
POWER DOWN Once the operating voltage is applied (+ and
GND), the modem is in the POWER DOWN
state.
The operating voltage for the GSM/GPRS
module is disconnected (the switching
regulator is off). In other words, the
software of the GSM module is not active.
A transition to the POWER DOWN state
always occurs in the following
circumstances:
• When the modem (module) is shut down
by means of AT commands (e.g. sleep
mode).
• When the external reset line is active.
27
Operating states / LED
Network search
(no SIM card,
no PIN number,
no GSM network)
In the network search state, the modem
searches for a GSM/GPRS network. All the
components in the GSM/GPRS modem
(module) that are not required are shut
down in several stages by the energy-saving
software.
This state is reached:
• From the POWER DOWN state: by an
active ignition (on) signal at the power
supply connection or
• From the STANDBY state: when the
network is lost (out of range)
28
Operating states / LED
Standby modem is ready for GPRS data transfer, but
ES75 modem no data is currently sent or received. Power
consumption depends on network settings
and GPRS configuration (e.g. multislot
settings).
Data Transfer GPRS data transfer in progress. Power
ES75 modem consumption depends on network settings
(e.g. power control level), uplink / downlink
data rates and GPRS configuration (e.g.
used multislot settings).
29
AT command control
The modem is controlled and programmed
by means of AT commands. The AT
command structure corresponds to the
MC75 module used. The AT commands can
be obtained from the ICM WM home page:
www.siemens.com/wm.
30
SW update
A SW update for the modem takes place via
the RS232 interface or the SIM interface.
These interfaces must be designed in such
a way that the upgrading of the modem is
integrated in the application. The software
can be obtained from the ICM WM home
page. The SW package is self-unpacking and
menu-driven.
31
Certification / maintenance
Certification Hereby, Siemens Information and
Communication Mobile, declares that the
cellular engine MC75 modem described in
this manual is in compliance with the
essential requirements and other relevant
provisions of Directive 1999/5/EC (R&TTE).
The Declaration of Conformity (DoC) has
been signed. In case of need, a copy of the
original DoC can be made available via your
distributor or system integrator.
Maintenance tips • Treat the SIM card with the same care as
your credit card. Do not bend or scratch
the SIM card or expose it to static
electricity.
• Wipe the modem housing with a moist or
antistatic cloth. Do not use a chemical
cleaning agent.
