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 assembly or service work.
• Avoid short circuits!
• Observe the relevant standards, regulations and guidelines on the installation 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 inappropriate 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
electrical devices, such devices must be disposed of at a designated collection

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".

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 retr o fitting 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 contains 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 common interface 5 according to the following picture and contact it to the
common interface.

Check that the plug contacts of the CA module are tightly seated in the
terminal strips on the
common
interface of the

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).

• Insert the module in grooves A of an open slot (with contact strip on the

• Balance the output levels of the channel strips "A" … "D" and level them to
the output levels of the modulators of other modules used if the difference in
level is ≥ 1 dB (page 17).

10dB compared to analogue cassettes at 64 QAM, and by 4 dB
compared to analogue cassettes at 256 QAM.

Chann el / frequen Cy
In this menu you can adjust the output channel (only at modulator A and C) or
the output frequency of the respective modulator.
—> The QAM signal is normally transmitted with a bandwidth of 8 MHz.
This means that you can only use the existing channel grid in the
range of channels C21…C69 (frequency grid 8 MHz).
The CCIR channel grid is 7 MHz in the range of the lower frequency
bands (channels C5 … C12, S2…S20). If 8 MHz QAM signal
packages are transmitted in these channel ranges, this will result in
interference (overlapping) and transmission problems.
For programming in these channel ranges and in the frequency rang-
es below them, we recommend starting with frequency 306 MHz
going back in steps of 8 MHz (see frequency table on page 40).
Please note thereby that many receivers cannot receive the channel
ranges S21…S41 (306 … 466 MHz).

screws in order to maintain compliance with current EMC regulations.
• Securely tighten the cable connections using an appropriate open-ended
spanner.
• After programming, connect the modulator output H to one of the input
sockets K of the output collector (page 10, fig. 4).
• Test the output level of the output collector according to the STC 160 assembly instructions and set the output level required for the cable system.
