Safety information

Radio devices have limitations in the vicinity
of electronic devices:

• Switch the TC35 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 TC35 Terminal off when flying.
Secure it so that it cannot be switched on
inadvertently.

• Switch the TC35 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 TC35 Terminal is a compact GSM
modem for the transfer of data, voice,
SMSand faxes in GSM networks. Industrial
standard interfaces and an integrated
SIMcard reader mean it can be used rapidly,
easily and universally as a dual band GSM
Terminal. 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
GSM Terminal TC35 T are described below.

The functionality of the Terminal
corresponds to the features of the TC35
module, to which a SIM card reader, an
RS232 interface, an analog interface for the
handset interface and a greater supply
voltage range have been added.

All the external interfaces of the GSM
Terminal TC35 T 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 TC35 Terminal 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 TC35
Terminal 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 Terminal on and off:

26

Switching

onTerminal

Simply applying supply voltage (+ to pin 1
and GND to pin 6) alone is not enough to
switch on the TC35 Terminal.

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 module. This still does not activate the
GSM module. Triggered by VBAT, a
transistor switch generates the IGT ignition
signal with a delay of approx. 100ms for the
GSM module. Only then is it switched on.
(Itexits the POWER DOWN operating
state.)

Startup

In its energized state, the GSM 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 GSM
module
VDD=supply voltage from the module

Activation of the RS232 control line DTR

The TC35 Terminal can be switched on in the
same way as via IGT_IN by activating the
RS232 control line DTR (high signal).

Note

The TC35 Terminal is switched on
immediately using the recommended plug­in power supply unit (see the above
explanation on startup).

Switching off /

resetting the

Terminal

The Terminal 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 TC35 Terminal. In this case, the GSM
module signs off before the watchdog
condition results in the specific switching off
of the supply voltages.

27

Startup

Activation of the PD_IN reset signal on
the power supply connection

The POWERDOWN line on the GSM
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
Terminal reset line is active (high) for at least

3.5s. This results in immediate, "hard"

disconnection, with the TC35 Terminal
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.

28

Operating states / LED

The LEDs display the following operating
states of the Terminal:

Operating states / LED

Note:

Usually, the network search takes only a
fewseconds till the Terminal 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 TC35 Terminal is in the POWER
DOWN state.

The operating voltage for the GSM 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 Terminal (module) is shut down
by means of AT commands (e.g. sleep
mode).

• When the external reset line is active.

In the network search state, the TC35
Terminal searches for a GSM network. All
the components in the GSM Terminal

in several stages by the energy-saving

active ignition (on) signal at the power
supply connection or

• From the TALK or STANDBY state: when

established between two subscribers via
the GSM network. Power consumption is at
the maximum and depends on the GSM
network availability and several connection
settings (e.g. DTX off/on, FR/EFR/HR,
hopping sequences and antenna coupling).

31

AT command control

The TC35 Terminal is controlled and
programmed by means of AT commands.
The AT command structure corresponds to
the TC35 module used. The AT commands
can be obtained from the ICM WM home
page: www.siemens.com/wm.

32

SW update

A SW update for the TC35 Terminal takes
place via the RS232 interface or the SIM
interface. These interfaces must be
designed in such a way that the upgrading
ofthe TC35 Terminal 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.
The Bootbox BB35 is required for updating
via the SIM interface.
