1 safety regulations
• The standards EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be
observed.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing should be carried out by authorised
electricians.
• Switch off the operating voltage of the system before beginning with assem-
bly or service work.
• Avoid short circuits!
• Observe the relevant standards, regulations and guidelines on the installa-
tion and operation of antenna systems.
• To ensure electromagnetic compatibility, make sure all connections are tight
and the covers are screwed on securely.
• No liability is accepted for damage caused by faulty connections or inap-
propriate handling of the device.
Check the head-end station STC 160 according to the safety instructions listed
in their assembly instruction.
Take precautions to prevent static discharge when working on the device!
Electronic devices should never be disposed of in the household rubbish. In
accordance with directive 2002/96/EC of the European Parliament and the
European Council from January 27, 2003 which addresses old electronic and

2.4 desCription
The Digital Transmodulator module "HDMU 790 C", in the following called
"module" converts four ISDB-T, DVB-T2/T/C modulated data streams into four
QAM modulated data streams. The module has one DVB-C/T/T2 resp. ISDB-T
input, one ASI input and one RF output.
The module is equipped with four channel strips ("A" … "D"). For each channel
strip tuner or ASI input can be selected. The channel strips consist of the digital
tuners, the digital signal processing units and an output converter.
Using adequate CA modules scrambled channels can be descrambled via
channel strips "A" and "C".

Four LEDs indicate if the respective channel strip is
switched on (LED illuminates) 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 de-
modulated transport streams.
The
QAM
modulated RF output signals are sent
through the RF output of the
module
to the output
collector (retrofittable accessory) of the head-end
station.
- 7 - HDMU 790 C
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.
The control of the module takes place via the control unit of the
head-end sta-
tion. To operate the
module
the software version of the control unit (head-end
station) must be "V 10" or higher. The operating software of the
module and
the
head-end station can be updated using a PC 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 module,
the software "BE-
Flash"
and the current assembly instructions
on the website "www.mygss.eu".
The
module
is designed exclusively for use in the STC 160 head-end station.
3 installation
– When using this module pay particular attention to the compliance of the
maximum module ambient temperature of +50°C.
– 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 a Ca module
The cassette is equipped with two common interfaces. This allows you to con-
nect two CA modules for 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 con-
tains all the information for authorisation, descrambling and subscription.
– Check with the distributor or manufacturer of the CA modules to be used
to ensure that they are suitable for descrambling several channels.
– The hardware and software of this cassette have been thoroughly prepared
and tested.
– Any changes made by programme provider to the structures in the pro-
gramme data might impair or even prevent this function.
– When working with the CA modules, please read the corresponding oper-
ating manuals from the respective providers.
• Insert the smart card
1 into the CA module
2 so that the chip
3
on the
smart card faces the thicker side (top) of the CA module (fig. 1).
• Push the CA module 2 without canting into the guide rails 4 of the com-
mon interface 5 according to the following picture and contact it to the
common interface.

3.2 installing the module
–
Check that the plug contacts of the CA module are tightly seated in the
terminal strips on the
common
interface of the
mod
ule 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.
• Open the locking device 1 in the direction of the arrow (fig. 2).

Fig. 2
• Insert the module in grooves A of an open slot (with contact strip on the
board at the rear wall of the housing) and gently slide it into the head-end
station until it makes contact with the board on the rear wall (fig.3).
• After installing the module close the locking device C in the direction of the
arrow (fig. 3). Ensure to get a well contact to spring B.

•
If required, connect the DVB-C/T/T2 resp. ISDB-T input E (input "In A")
on the
mod
ule (fig. 4) to the preinstalled Fterminals in the rear wall of the
head-end station via the cable inlets I using a RF cable made on-site.
• If required, connect the ASI input D to a corresponding ASI signal source.
• After programming, connect the modulator output H to one of the input
sockets K of a retrofitted output collector.
