DESCRIPTION
DVB-T signal Twin transmodulator in DVB-T (TTT-TWIN-CI
G
8000) or DVB-C (TCT-TWIN-CI 8000) with Conditional
Access. DVB-CI. 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. 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.

INST LL TION ND ST RT-UP
- The power sources must be disconnected from
the mains before connecting or disconnecting the
module.
Insert the C M into the module ( look position N 10
G
in the CONTROLS schema) before placing the module
on the frame (STT-CI 8000).
Connect the earth connection of the frame to the earth
G
connection of the antenna installation.
Fix the modules to the frame in the order shown in the
G
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
G
coaxial bridge (Ref. 83814) and load the free output(s)
(Ref. 84011).
with 75
Join the RF channel outputs (8) via the F-F coaxial bridge,
G
and load the free output of module 1 with 75 , beside
the power source.
Connect the Supply bus BA 807 ref. 83807 between the
G
modules (5) and the SPS.
Connect the antenna drop cables to the corresponding
G
inputs (1).
Connect the power source to the mains.

I
WORKING TEMPER TURE
The modules have to be refreshed for their correct
G
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 PROGR MM TION
The modules can be programmed:
Through the UCF 300 Control Unit (Ref 85115) in local
G
mode, following the steps explained in this manual.
Through a PC in local mode. In this case, it's necessary
G
to have a MCU 8000/LPU 8000 unit and the "8000 series"
interface installed in the PC.

DISPL Y INDIC TIONS

The UCF 300 control unit has two rows of alphanumerical
G
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
G
row, this indicates that one of the 5 functions has been
entered.
If data appear on two rows of the display, the
G
parameter to be adjusted is being displayed.
The right arrow shows how to enter to change the
G
parameter setting.
A flashing box indicates that the parameter setting can
G
be modified using the
(press the button to validate).
OK
A "+" sign followed by the name of the service indicates
G
that this service is in the output multiplex.
A " * " sign before the name indicates an encrypted
G
service.
A " 1 " or " 2 " after the service name indicates in which
G
output has been actived the service.
