DESCRIPTION
DVB-S and DVB-S2 signal transmodulator in DVB-T
●
Free-to-Air (STT 8000) and with Conditionnal Access
DVB-CI (STT-CI 8000). Admits QPSK or 8PSK input
signals and modulated signal delivery in COFDM.
Allows satellite programs to be viewed with DTT receivers.
1st IF SAT signal with digital programming is converted
to the RF band between 50.5 and 858 MHz modulated
in DVB-T. Handles MPEG-2 or MPEG-4 signals enabling
selection of programs delivered on output.
■
INSTALLATION AND START-UP
- The power sources must be disconnected from
the mains before connecting or disconnecting the
module.
Insert the CAM into the module ( look position N 10
●
in the CONTROLS schema) before placing the module
on the frame (STT-CI 8000).
Connect the earth connection of the frame to the earth
●
connection of the antenna installation.
Fix the modules to the frame in the order shown in the
●
application example (see page 3), with the power source
on the right and the amplifier on the left of the unit.
Make the signal distribution of the antenna(s) via the F-F
●
coaxial bridge (Ref. 83814) and load the free output(s)
with 75 Ω (Ref. 84011).
Join the RF channel outputs (8) via the F-F coaxial bridge,
●
and load the free output of module 1 with 75 Ω, beside
the power source.
Connect the Supply bus BA 807 ref. 83807 between the
●
modules (5) and the SPS.
Connect the antenna drop cables to the corresponding
●
inputs (1).
Connect the power source to the mains.
●
■
WORKING TEMPERATURE
The modules have to be refreshed for their correct
●
operationt. It's recommended to install the modules in
the housing with fan (Ref 83806) or, when installing on
a 19" rack, to use the Rack ventilation Unit (ref 83801)
When there are few modules to install, it's possible to
use the fan VNT 800 on the wall frame (fig N 1).
■
MODULES PROGRAMMATION
The modules can be programmed:
Through the UCF 300 Control Unit (Ref 85115) in local
●
mode, following the steps explained in this manual.
Through a PC in local mode. In this case, it's necessary
●
to have a MCU 8000 unit and the "8000 series" interface
installed in the PC.

UCF 300: FUNCIONES DE LAS TECLAS
❏ ❏
The buttons are for vertical menu scrolling.
▲ ▼
●
a) On the programming menu they are for selecting the
function to be programmed.
b) A parameter can be selected within a function.
c) A parameter setting can be modified within a
programmable parameter.
The buttons are for horizontal scrolling through the
●
programming menu, e.g.:
Function parameter
The button is for moving right.
●
The button is for exiting without changing the setting:
●
escape.
The button is for validating the data item programmed.
● OK
■
DISPLAY INDICATIONS
The UCF 300 control unit has two rows of alphanumerical
●
characters. The data display mode and programming
diagram on page 8 are a guide to this process:
If the characters are all upper case and on the upper
●
row, this indicates that one of the 5 functions has been
entered.
If data appear on two rows of the display, the
●
parameter to be adjusted is being displayed.
The right arrow shows how to enter to change the
●
parameter setting.
A flashing box indicates that the parameter setting can
●
be modified using the
(press the button to validate).
OK
A "+" sign followed by the name of the service indicates
●
that this service is in the output multiplex.
A " * " sign before the name indicates an encrypted
●
service.
