DESCRIPTION
DVB-T signal regenerator with Free-to-Air (TTT 8000) and
●
Conditional Access DVB-CI (TTT-CI 8000) versions. Admits
COFDM input signals, and regenerates their contents to get
a good MER level in the COFDM modulated output channel.
The encrypted services will be opened with the Conditional
Access Module for the TTT-CI 8000. The output frequency
could be programmed in the band between 50.5 and
858 MHz. 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
●
operation. 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/LPU 8000 unit and the "8000 series"
interface installed in the PC.

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

The
button is for moving right.

The
button is for exiting without changing the setting:

The
button is for validating the data item programmed.

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.
