Safety information
Radio devices have limitations in the vicinity of electronic devices:
• Switch the modem off when you are in a hospital or near
medical devices like pacemakers or hearing aids. The modem
may interfere with the operation of these devices.
• Switch the modem off when flying.
Secure it so that it cannot be switched on inadvertently.
• Switch the modem off when you are near petrol stations, fuel
depots, chemical plants or blasting operations. The modem 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 modem. 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.

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 on modem
Simply applying supply voltage (+ to pin 1 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.)
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 / resetting the modem
The modem can be switched off in two different ways:
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.
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.

Siemens EDGE Speed ES75 User´s Guide
Operating states / LED
The LEDs display the following operating states of the modem:
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.

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)
Standby ES75 modem
modem 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).
Data Transfer ES75 modem
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).

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
.
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.
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.
