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.

Safety and
installation
information
•The Terminal should be installed and set
up only by qualified personnel.
•Connect a fast 1.25A fuse to the incoming
line for the positive supply voltage to
protect the Terminal.
•If a power supply unit is used to supply the
TC35 Terminal, it must meet the demands
placed on SELV circuits in accordance with
EN60950. When using batteries and
accumulators, adhere to the relevant
regulations.
•The maximum permissible connection
length between the TC35 Terminal and
the supply source is 3m.
•Your supplier will be pleased to provide
you with a detailed technical description
and technical support for the SIEMENS
TC35 Terminal.
Attaching
theTerminal
The TC35 Terminal can be attached with two
screws. Use screws approx.50 mm long
and Ø 3mm. The TC35 Terminal can be
attached to a top-hat rail using an additional
fixture (see the following page).

Installation
Mounting kit for top-hat rail installation
The TC35 Terminal can be attached to a
35mm top-hat rail using this mounting kit.
There are two screws that are used tofix the
top-hat rail adapter to the TC35 Terminal.
The TC35 Terminal can be inserted onto the

Interface description
The following interfaces are available on the
TC35Terminal:
•Connector for the plug-in power supply
unit
•Handset connector
•Mini-SIM card holder
•Antenna connector FME (male)
•RS232 interface (V.24/V.28 on the D-Sub

Polarity reversal protection
Polarity reversal protection is implemented
by means of a power diode. The diode has a
reverse voltage of 400V.
Overvoltage protection
Overvoltages are suppressed by a Zener
diode after the polarity reversal protection
diode.
Fuses
A permanently installed, non-replaceable
fuse in the TC35 Terminal ensures electrical
safety in the event of faults. Connect a fast
1.25A fuse to the supply line of the positive
supply voltage for general protection of the
Terminal, see "Safety and installation
information" on page9.

Interface description
Handset connector The handset is connected via a 4-pin Mini-
Western socket. The audio interface has a
symmetrical design. The audio interface can
be configured by AT commands.
Threeaudio modes are prepared in the GSM
module for this purpose.
Mode 1 (default):
The "Handset for Cellular Engine Siemens
Terminal M20T, MC35T, TC35T, DSB35"
can be connected to the TC35 Terminal
(approved configuration and recommended
handset).
Mode 4:
Any handset can be connected to the
TC35Terminal. The audio parameters can be
adapted by means of AT commands. New
approval must be obtained for this
combination.
Mode 5:
The frequency responses have a linear
setting in this mode for any audio
equipment. Echo suppression and side tone
are switched off.
