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

Product descri tion
The TC35 Terminal is a compact GSM
modem for the transfer of data, voice,
SMS and faxes in GSM networks Industrial
standard interfaces and an integrated
SIM card 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 25 A 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 3 m
 Your supplier will be pleased to provide
you with a detailed technical description
and technical support for the SIEMENS

Polarity reversal protection
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 TC35 Terminal ensures electrical
safety in the event of faults Connect a fast
1 25 A fuse to the supply line of the positive
supply voltage for general protection of the
Terminal, see "Safety and installation
information" on page 9

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
Three audio modes are prepared in the GSM
module for this purpose
Mode 1 (default):
The "Handset for Cellular Engine Siemens
Terminal M20 T, MC35 T, TC35 T, DSB35"
can be connected to the TC35 Terminal
(approved configuration and recommended
handset)
Mode 4:
Any handset can be connected to the
TC35 Terminal 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
