2.4 desCription
The Head-end Digital Modulator COFDM "HDM 660 T" , in the following called
COFDM module converts two DVB-S (QPSK) modulated data streams into two
DVB-T ( COFDM) modulated data streams. The COFDM module has two SAT-IF
inputs and one HF output. Components (e.g. LNB) which are connected up-
stream can be powered through the SAT-IF inputs.
The COFDM module is equipped with two channel strips ("A" and "B"). The
channel strips consist of the digital SAT tuners, the digital signal processing
levels and an output converter. The output channels are suitable for neighbour-
ing channel assignment and free tunable (no automatic neighbouring-channel
assignment). The channel strips are indicated in the head-end station display
with "Bx …A" and "Bx …B".
Using an adequate CA module scrambled channels can be descrambled via
channel strip "A". The control of the module takes place via the control unit of
the head-end station.
Two LEDs indicate if the respective channel strip is switched on (LED illumi-
nates) or off, and also provide an indication of the signal quality based on
their colour.
The integrated TPS module (Transport Stream Processing) processes the data
from the demodulated transport streams.
The COFDM modulated HF output signals are sent through the HF output of the
COFDM module to the output collector.
When the head-end station is switched on, the two-line LC display shows the
"SETUP" menu and the software version of the control unit. The head-end sta-
tion output level can be adjusted in this menu.
To operate the COFDM module the software version of the control unit (head-
end station) must be "V 8" or higher. The operating software of the COFDM
module and the head-end station can be updated using a PC or notebook and
the software "BE-Flash" via the 9-pin D-SUB socket on the head-end station.
You can find the current operating software for the head-end station and the
COFDM module, the software "BE-Flash" and the current assembly instructions
on the website "www.gss.de".
The COFDM module is designed exclusively for use in the STC 160 head-end
station.

tps module funCtions
After decoding QPSK-modulated signals, the demodulated data streams can
be accessed via the integrated TPS module. These data streams, also called
transport streams, contain several stations in all their components (video, au-
dio, data and service information), which can be changed using the TPS mod-
ule.
In the station filter individual stations can be (de-)activated to fill the output
data rate defined with the COFDM settings.
The transport stream contains data in the form of tables which the receiv-
ers evaluate and require for convenient use. The TPS module can adjust the
"Network Information Table" (NIT) to accommodate the new station data. The
"NIT" contains data which is required by the set-top box for the automatic
search feature.
3 installation
– Ensure the head-end station is mounted so it will not be able to vibrate.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– Before installing or changing a module, switch off the head-end station or
unplug the power cable from the mains power socket.
 TakemeasurestoprotectagainstESD!
 • Open the housing of the head-end station in accordance with the assembly
instructions for the STC 160.

3.1 retrofitting aCa module
The COFDM module is equipped with a common interface for CA modules of
various scrambling systems and service providers. Scrambled channels can
only be descrambled with a CA module suitable for the scrambling system and
the corresponding smart card. The smart card contains all the information for
authorisation, descrambling and subscription.
– Check with the distributor or manufacturer of the CA module to be used to
ensure that it is suitable for the reception of several channels.
– The hardware and software of the COFDM module have been thoroughly
prepared and tested.
– Any changes made by program providers to the structures in the program
data might impair or even prevent this function.
– When working with the CA module, please read the corresponding operat-
ing manual from the respective provider.
 • Insertthesmartcard 1into the CA module 2so that the chip 3 on the
smart card faces the thicker side (top) of the CA module (fig. 1).
 • PushtheCAmodule2without canting into the guide rails 4of the com-
mon interface 5according to the following picture and contact it to the

3.2 installing the Cofdm module
– Check that the plug contacts of the CA module are tightly seated in the
terminal strips on the common interface of the COFDM module and make
sure there is reliable contact.
– When installing a module, make sure that it is inserted in one of the long,
numbered grooves in front of the contact strip on the board at the rear wall
of the housing.
– The shorter, non-numbered grooves without a contact strip on the board at
the rear wall of the housing are for add-on modules only.
 • Open the housing of the head-end station in accordance with the assembly
instructions for the STC 160.
