1 safety regulations and notes
• The devices meet the EU directives 2011/65/EU, 2014/30/EU and
2014/35/EU.
• This device is subject to the provisions of protection class I. Operate the
device only to mains sockets with protective conductor connection!
• If the power cord needs to be replaced, only use an OEM power cord.
• The standards EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be
observed, especially concerning equipotential bonding and earthing.
• Observe the relevant country-specific standards, regulations and guidelines
on the installation and operation of antenna systems.
• Before starting installation or service work disconnect the receiving system
from mains.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• For a complete disconnection from the mains, the mains plug must be pulled
out of the mains socket. Ensure that the mains plug can be pulled out without
difficulties.
• The head-end station should only be installed in a room where the permis-
sible ambient temperature range (0 °C … +50 °C ) can be maintained, even
during fluctuations in climatic conditions.
• Make sure there is a minimum space of 10 cm on either side and 50 cm
above and below.
• To avoid too strong interacted heating of the head-end stations it is not
admissible to mount them one upon the other without using thermic precau-
tions (e.g. permanently air recirculation, ventilation, heat deflectors etc.).
• If additional fans are to be used to circulate the air, ensure that the system
will be shut down (disconnected from mains) should any one of the fans fail.
• Install the head-end station
- in a dry, dust-free environment, in such a manner that it is protected from
moisture, fumes, splashing water and dampness
- where it is protected from direct exposure to sunlight
- on a vibration-free wall or floor construction
- not within the immediate vicinity of heat sources
• In case of the formation of condensation wait until the system is completely
dried.
• Ensure that the head-end station is adequately ventilated.
• Do not cover the ventilation openings!
• Do not install the head end in cabinets or recesses which are not ventilated.

- 4 - STC 4-16 light
• Do not place any vessels containing liquids on the head-end station.
• Do not place anything on the head-end station which could initiate fires
(e.g. candles).
• Due to the risk of fires caused by lightning strikes, we recommend that
all mechanical parts (e.g. distributor, equipotential bonding rail, etc.) be
mounted on a non-combustible base. Wood panelling, wooden beams,
plastic covered panels and plastic panels are all examples of combustible
bases.
• Avoid short circuits!
• To ensure electromagnetic compatibility, make sure all connections are tight
and that the covers are screwed on securely.
• No liability is accepted for damage caused by faulty connections or inap-
propriate handling of the device.
• The firmware contains components which are licensed as Open Source
software. The components to which this relates and the respective license
terms can be called up via menu Help/Licences.
This parts of software source code can be provided at cost price on CD
upon request. The licensee is granted a non-exclusive right of use for the
Open Source Software by the respective right holders used; the conditions
stipulated by the respective valid license terms apply. The license terms of
this license only apply to the components which are not listed as Open
Source software.
In relation to the licensor the regulations on liability and warranty in these
license terms apply for the whole software. The liability and warranty regu-
lations of the Open Source licenses only apply in relation to the respective
right holders.
• Test the firmware versions of the device and update them if necessary. The
current firmware version can be found at "www.mygss.eu".
Take action 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 facility. At the end of its service life,
please take your device to one of these public collection facilities for proper disposal.

gen e r al
The station is equipped with four SAT IF inputs, one RF output and one test
output (–25 dB). It is preset to receive the most popular ASTRA transponders.
Different programming is possible at any time. Each of the 16 tuners can be
assigned to any SAT input. Via the RF output of the station, the QAM modulated
RF output signals are output. The output levels of the channel strips can be set.
The configuration of the station is to be done via an HTML user interface via a
PC and a standard HTML browser connected to the LAN input.

3.1 insta l l i ng t h e d eviCe
– The device must not be operated lying down, since the function of the heat
sink will be severely restricted. Only with vertically arranged cooling fins
sufficient cooling is ensured.
– The device should only be installed in a room where the permissible ambi-
ent temperature range (0 °C … +50 °C ) can be maintained, even during
fluctuations in climatic conditions.
– Mount the device on a non-combustible base.
– Use mounting material suitable for the wall properties.
– Position the device with a minimum distance on the left and right side of 10
cm, below and above 50 cm.
• Attach four mounting screws at the installation site. The drilling distances
are shown in the drawing below.

• Connect the attached mains cable to the IEC connector C14 9.
—> If you would like to integrate the device to an existing plant, now
first you should connect it to the mains and perform all settings (Con-
figuration page 11).
• Connect the mains cable to a mains socket with protective conductor con-
nection. Thereby note the voltage specified on the device.
—> This device has no power switch and starts immediately after con-
necting the operating voltage.
• Configure the device (page 11).
• If the programming is finished connect the RF output 7 to the cable net-
work.

4 Configuration / uPdates
The configuration of the station is to be done via an HTML user interface via a
PC and a standard HTML browser.
4.1 initial C on fi g ur ati on
• Connect a PC via a LAN cable directly to the LAN input 11.
—> The PC and the head-end station must be within the same network
(same IP address range). Cookies must be accepted and JavaScript
must be active.
Use current browser versions.
—> Example for IP address setting with Windows 7 operating system:
• For the initial setup open the properties for TCP/IPv4 of the PC:
> Control Panel
> Network and Sharing Center
> LAN connection
> Properties

- 12 - STC 4-16 light

152 In column Chan. / Freq. [MHz], enter the desired output channel/fre-
quency of the individual lines.
—> Double assignments are indicated by a
warning icon .
—> A output signal is normally transmitted
with a bandwidth of 8 MHz. This means
that you can only use the channel centre frequency of 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). 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 32).
Please note thereby that many DVB-T receivers cannot receive the
channel ranges S21…S41 (306 … 466 MHz).
153 In column SR [kS/s], enter the desired output symbol rate of the individual
lines.
—> The background colour in column Line indicates an output data
overflow.
In this case increase the output symbol rate or the QAM modulation
or remove stations from the data stream using the station filter.
154 In column Modulation, select the desired kind of modulation of the indi-
vidual lines – QAM 16, 32, 64, 128, 256
—> The background colour in column Line indicates an output data
overflow. In this case change the output settings or remove stations
from the data stream using the station filter.
155 For exceptional cases and "older" digital cable receivers, in column
Spectrum the spectral position of the user signal can be inverted (invers).
Factory default is "normal".

156 In column Level [dB], balance the output levels of the different lines
(0…-10dB). Therefore measure and note down the output level of each
modulator. Adjust the higher output levels to the output level of the modu-
lator with the lowest output level incrementally.

161 Balance here the master output level of the station to the level of the ca-
ble network (0…-31dB; off).
