DIGITAL TV HEADEND
1. GENERAL
1.1 Description
The DTTV system (Digital to TV) is based on a TV headend that receives television
signals from different sources. It processes them for its integration into an output signal in
Digital Terrestrial (DVB-T) format. In this way, the signal can be distributed
network with multiple receivers, keeping the original wiring installation but distributing in
high-quality format. This system is applicable to hotels, hospitals, shopping centres,
universities, etc. that is, local distribution networks that want to distribute media content in
digital quality.
The DT-802 is the control and power module, therefore is the most important
module of the DTTV system. The control modul
headend via modem-cable.
e is connected to all the modules of the
on a TV
The DT-802 allows controlling and configurating each module individually. The user
can manage and
remote mode. In local mode, the module is managed via the keypad and the LCD screen
placed on the frontal of the DT-802. In remote mode, the control module is connected to a
computer through a network cable and it is managed by using the specific software
control.
The difference between the control module DT-800 and
DT-802 is that the DT-802 has a redundant power system based on two totally
independent batteries that can be hot-swapped without affecting the network distribution
system. The redundant battery works when the other battery fails due to a malfunction
or a failure of the supplier. It warns the user using a buzzer and a light.

3. INSTALLATION
3.1 DT-900 Sub-rack
The DT-900 is a metallic casing (sub-rack), where the DTTV modules are
installed (Fig. 1).
Supplied accessories allow the subrack to be set up in two ways: Installing it in a
19 " rack cabinet (Fig. 2) or anchoring it on a wall.
The wall anchoring system allows, through a tilting system, accessing the rear of
the subrack, where the connectors are placed (Fig. 3).
One subrack can contain approximately 8 modules. One of them must be the
control module DT-802.
The sub-rack DT-900 is supplied with an user’s manual, which describes in detail
the steps to complete the assembly.

3.2 Installing modules in the DT-900.
To install a module in the subrack, you should slide the module into the subrack,
screwing it to the frontal guide (Fig. 4).
In order to get a tidy installation of the modules you should follow the next
advises:
• Place the DT-802 at the left end of the sub-rack.
• Place the DT-700 and / or DT-710 at the right end of the sub-rack.
• Place the DT-101/102 and the DT-301/302 side by side in the case they were
paired.
• Place the rest of the modules together, without leaving a gap between them.
English

Following these advises you will achieve a tidy installation and the best
configuration for later maintenance or new modules addition.
3.3 Connecting wires
The modular composition of the DTTV headend makes it flexible to adapt it to
customer needs.
