1. Savety and operang instrucons
When assembling, starng-up and adjusng the modules, it is necessary to consider the system specic references
in the instrucon manual.
The modules may only be installed and started up by authorized technical personnel. Only the mounng styles
described in the Quick Start Guide are supported.
When installing the modules into the receiving points, the adherence of the EMC regulaons is to be ensured.
The installaon and wiring have to be done without voltage. For installaon, only use the supplied accessories
(DIN rail clip with screws and 19“ accessories).
All acve modules may only be powerd by the power supplies of the HELIOS family, HELIOS-P1 or QUASARIOS.
Only connect the module with the provided accessory cables.
The mains voltage and the operang voltage of the modules working by DC have to be in compliance with the
operang parameters described in the technical data.
With all work the defaults of the DIN EN 50083 have to be considered. It is especially important to follow
DIN EN 60728-11.
The unit must only be mounted vercally. The venlaon slots as well as the circulaon perforaon of the
modules is not be obstructed in any way.
If installed in mounng cabZinets a adequate heat circulaon must be guaranteed. The mounng in closed
cabinets without air sucient ow is not allowed.
For DIN rail mounng is important to note that between the heat sink and a neighboring module, a distance of
0,79" is required. If the modules mounted on top of each, so they must be spaced 7.87" apart.
For 19“ mounng all devices in the rack must be ed with 19“ Edge Guide. Mounng the device using only the
screw holes at the front panel is insecure and discouraged. Furthermore, the operaon of a fully occupied rack is
only allowed with an underlying 1-U fan box (at least 3 fans, 6,93" deep).

5. General
The Smart Business Line (SBL) is a modern headend system, that is disnguished by its modular and compact design. A
userfriendly operang concept facilitates setup, conguraon and maintenance of the system.
The module converts digital terrestrial signals into QAM signals to transmit it in cable networks. In this case, up to 8
QAM channels from the available DVB-C /-T /-T2 signals are generated, which are aached via two inputs. The internal
processing allows the output of DVB signals in full HD resoluon.
6. Funconal descripon
The DVB-C /-T /-T2 signal is fed through 2 inputs or a loop-through input by a switching matrix to the input parts and
their demodulators. The resulng 8 transport streams are processed with a high-performance FPGA. The transport
stream processing or ltering, the QAM modulaon and the freely adjustable up-converng in the cable network range
(45 ... 862 MHz) take place in the FPGA.
The eighold modulator is adjacent channel compable. A highly-clocked digital to analogue converter (DAC) does the
spectrally pure output of the cable signal. Aer amplicaon and sum level adjustment, the cable signal is coupled
through a direconal coupler to the output jacks.

7. Sengs by the web interface
To use all funcons of the module acvate Java Script in your browser sengs.
Sengs via checkbox are applied immediatelly, but not stored in memory! So they would be lost on a possible
restart of the module. To save these sengs the “send“ buon must be pressed.
Please send and store your sengs by pressing the“send“ buon aer each change.
7.1 Network connecon to the computer
System requirements:
- PC/ laptop with 10/ 100 Mbit Ethernet interface
- Internet browser (e.g. Windows Internet Explorer), capable JAVA script
Setup the connecon:
The module has to be connected to PC network using an Ethernet cable. The default IP address of the module is
192.168.1.100.
In order to access the web interface of the module from a PC, the PC has to be in the same subnet (192.168.1.XXX;
subnet mask 255.255.255.0), where XXX is not used by any other module in this subnet.
If mulple modules are connected to the same network each module must be set to its own unique IP address to avoid
address conicts.
Aer these sengs, the IP address of the PC has to be adjusted to match the network. Now the modules can be accessed
via browser with the new IP address.
If acvated (Setup→GUI Sengs→Acvate user and keyword check), the user has to log in now (»chapter 7.2.7).
Aer successful registraon or a connecon establishment without password (default seng) the start page of the
module is displayed (»chapter 7.2.1).

7.2 Seng of individual parameters
Here you can set certain parameters of the module or perform conguraons. The various seng menus can be
selected in the navigaon tree on the le side. The seng is supported by an online help. If you mouse over a parameter
explanaons of this parameter are displayed in an orange colored text box in the lower part of the screen. By sengs
in the “Setup“ menu (»chapter 7.2.7) can be selected so that the help is displayed in the status bar of your browser.
Therefor seng changes in the browser opons could be necessary.
By default status informaon for the module is displayed below the navigaon tree. An opon to move it on the right
side instead is available (GUI »chapter 7.2.7).
All eight channels are listed individually. A green LED symbol in front of “channel 1 ... 8“ means that input and output
are synchronized and that the channel operates without error. An orange colored symbol indicates that an error has
occurred. An overview of the status of various parameters of the channel is obtained by clicking the corresponding
channel. A transparent LED symbol means that the channel is not congured or the RF output is turned o.
The “Power“ LED indicates the connecon status between the network interface and the module. The “System“ LED
gives an overview about the status of the system parameters.
If you click on a channel an overview window is displayed. The pop-up window closes aer 20 seconds or by cklicking
in its lower part.
In all menus it‘s possible to switch the language between German and English on the top right.

7.2.1 Menu "Overview"
This page provides an overview of the 8 channels. "SYNC" is diplayed if a channel works correctly. If an error occurs or
the channel is o a corresponding message is shown.
The interface of the A-QAMOS MUX is separated for the mulplexer and QAM output. If a channel works correctly,
"MUX" resp. "QAM" is displayed in a green color. An inacve mulplexer is not displayed.
Below the status window all modules belonging to the headend are listed (headend »chapter 7.2.7 ). Funcons across
modules like the NIT exchange between modules of the QAMOS group can be done on all listed modules.
The individual components of a headend are listed with their IP address. The IP address is a link which leads to the
module. If no headend was congured, a "Search" buon leads to the "Setup" menu and scans the network for other
A-LINE-SBL and SBL modules. Then all available modules are listed. They can be selected and added to the headend.
By clicking the "Logout" buon the user is logged out and the login window is displayed.

7.2.2 Menu „Input”
In this menu the adjustment of the up to 8 tuners is done to receive the required programs.
Port 1 (IN) is always congured as an input, Port 2 (IN / OUT) can be congured as input or loop-through output. Each
port can be equipped with an input aenuaon of 15 dB.
Now select the tuners (1 ... 8). Per used tuner the receiver sengs are done according to the modulaon (DVB-T, DVB-T2,
DVB-C) and to the receiving program packages.
