Function
The OCS409 has four inputs for connecting, four arbitrary satellite polarisation levels, one in-
put for connecting terrestrial signals (CATV, DVB-T, FM).
Additional to that it has an output for connecting to the home coax installation and connectors
for USB flash drives and the power adaptor.
The OCS409 selects out up to 9 transponders, coming in by one of the 4 inputs and arranges
them together with the terrestrial signals and puts them out on the output for distribution over
home coax installation.
The selection of transponders is done by a configuration file, which is loaded into the device by
a USB flash drive.
The configuration file can be created on a PC by using the provided software. To create the file
knowledge about satellite transponder lists (e.g. on the Internet) is necessary.
The selected and by home coax network distributed transponders will be converted to tele-
vision channels by an DVB-S(2) receiver, as well as for the satellite television.
There are no special receivers needed in combination with the OCS409, all internal or ex-
ternal satellite receivers available on the market can be used. It is only necessary to make a
transponder search for each in a single wire network used receiver. A receiver with preprogram-
med transponder lists helps to simplify this procedure.
Transponder:
For the satellite television a transponder is a container, it contains TV-
and FM-Channels that are compressed and packaged by technical proce-
dures. Then these containers will be arranged like a pearl necklace to a
satellite carrier frequency and transmitted from the satellite to the earth
using a polarisation level.
Polarisation plane:
In relation to a satellite reception, 4 polarisation planes are defined.
Two planes differ in a frequency range. The LOW band (10.7 GHz
to 11.7 GHz) and the HIGH band (11.7 GHz to 12.75 GHz). These
frequency ranges get an offset in dependence of control voltage so that
only one range can be putted out.
The two other planes differ in a radiation direction, VERTICAL
and HORIZONTAL.
Therefore they are called:
•
VL (vertical-low band),
•
VH (vertical-high band),
•
HL (horizontal-low band) and
•
HH (horizontal-high band)
plane.
