1. Safety and operating instructions
When assembling, starting-up and adjusting the modules, it is necessary to consider the system specific references in
the manual instruction!
The modules may only be installed and started up by authorized technical personnel!
When assembling the modules into the receiving points, the adherence of the EMC regulations is to be secured!
The assembly and wiring have to be done without voltage!
All active modules may only be operated with the Headend Controller HCB x00 or Bus Extender BEB x00!
The main voltage and the operating voltage of the modules working by DC have to be in complience to the operating
parameters described in the technical data.
With all work the defaults of the DIN EN 50083 have to be considered! Especially the safety relevant execution of the
DIN EN 60728-11[4] is necessary!

3. General
The SAT-TV transmodulator STB 016 is a module of the head end system B-LINE wich is conceived as a complete system for
middle-sized networks.The module converts one DVB-S/ S2 transponder into the digital cable standard DVB-C or ITU-T J.83 Annex
B or C. The signals will be transcoded into cable TV channels. All modules will be programmed via a central control unit (HCB x00)
and are working fully independent afterwards. The status of the modules are displayed via LED’s (see chapter 7 “Meaning of status
LED`s on front panel“).

The manual instructions of the Headend Controller HCB x00 and the Bus Extender BEB x00 have to be considered!
4. Front view
5. Functional description
The SAT-IF input signal is fed to the DVB-S/ -S2 front end, where the selection of a transponder and its QPSK or 8PSK demodulation
is done and a data stream is generated. All services of the resulting transport stream which shall be processed into the QAM modula-
tor will be choosen by controling software of the module. The SI and PSI tables affected (i.e. the PAT, PMT, SDT, EIT) are automatically
corrected. The Headend Controller serves to generate an NIT (Network Information Table) into the transport stream. This is required
to enable the receiver (such as Set-Top-Box) to tune in automatically. The changed SI an PSI tables are fed into the QAM modulator
and an IF signal is generated at the output channel. There is a free choise of frequency in the output channel from 45 to 862 MHz.
On the output side, the modulator does not leak to adjacent channels. So that errors in level can be signalled if the load fluctuates
(the red LED will flash and a trap message will be sent), a reference level is generated. Every time the level for frequency figures are
programmed, automatic measurement of the refence level takes place; this function will, however, not start until 100 seconds have
elapsed after start-up of the system. This function can be enabled or disabled in the main menu.
6. Adjustments
6.1 Adjustment with the Headend Controller
· Adjustment of the addresses at the Bus Extender BEB x00 and at the modules
· Activation of the programming mode on each module by selecting the line (BEB x00) and the module position (01... 15) at the
Headend Controller(HCB x00) → yellow LED illuminates until the beginning of the parameter adjustment
· Adjustment of the STB 016 parameters (see chapter 9) →green LED is switched on
· After the programming the STB 016 will be automatically switched into the operating mode
→yellow LED flashes shortly / green LED is switched on
6.2 Adjustment with PC/ laptop
· Prerequisite for the remote programming is an “online - connection” acording the IP standard and an ethernet connection at the
PC/ laptop
· Adjustment of the line/ position addresses at the Bus Extender BEB x00 as well as at the modules
· At the Headend Controller HCB x00 input IP address (e.g. 192.168.001.001))
· For “direct connection” between a PC and HCB x00 use crossover cable (RJ 45)
· For connection over a HUB use a normal straight throught patch cable
· Start-up HTML browser and put in IP address as target address
· If connected correctly the web interface will be opened on the PC/ laptop and a blue LED (LINK) at the HCB x00 will be lit up.
· All adjustments of the modules are specified on the web interface.

Affirming the query, all settings made on the EEPROM will be
deleted and replaced by the default settings. The modul will go
back to these default values. Once the setting process is over,
there will be automatic return to the main menu. It takes about
one minute.
