2.3 Description
The COFDM AV module HDCT 460 AV, in the following called digital module, has
a COFDM AV converter which simultaneously converts four COFDM modulated
channels into AV signals using two DVB-T tuners.
The digita l module has two DVB-T inputs. Via the AV interface, the decoded
video and audio signals are fed to the corresponding modulator module. From
there, they are fed to the HF output collector of the head-end station, through
which the level of the output signal can be adjusted via the software in the
head-end station.
The channel strips “A” “B”, “C” and “D” can be individually programmed. This
means it is possible to select up to 4 channels out of two data streams. The fol-
lowing table shows the allocation of the selectable number of channels to the
tuners:
Tuner “A” Tuner “D”
Number of
channels
31
22
For example, if three channels from tuner “A” will be used, one channel from
tuner “D” can be used. If two channels from tuner “A” will be used, two chan-
nels from tuner “D” can also be used.
Signal transfer principle:
The operating software of the digital module can be updated via the 9-
pin SUB-D socket on the control unit of the head-end station using a PC or
notebook and the Software “BE-Flash”. You can find the current operating
software on the website “www.gss.tv”.
This digital module is designed exclusively for use in the STC 160 head-end
station.

3 Installation
Caution
Before installing or changing a module, switch off the head-end station or
unplug the power cable from the mains power socket.
Take precautions to prevent electrostatic discharge when working on the
device!
• Open the housing of the head-end station according to the instructions in
the STC 160 assembly instructions.
3.1 Installing the digital module
Caution
– Always position modules which belong together next to each other. The
digital module must be installed to the left of the modulator module.
– Insert the digital module in a long numbered groove in front of a contact
strip on the board at the rear wall of the housing.
The shorter not numbered grooves without a contact strip on the board
at the rear wall of the housing are for add-on modules only.

Note:
Slots 1 (digital module) and 2 (modulator module) are shown in the illustra-
tion. The open slots in between (without a contact strip on the board at the
rear wall of the housing) are intended for add-on modules.
• Insert the digital module in grooves Aand Bof an open slot (with contact
strip on the board at the rear wall of the housing) next to the associated
modulator module.
• Gently slide the digital module into the head-end station and ensure that
it makes contact with the contact strip on the board at the rear wall of the
housing.

5 Programming
5.1 Preparation
• Connect the digital module to a programmed modulator module.
• Connect the test receiver to the HF output on the modulator module.
• Adjust the test receiver to the output channel of the channel strip to be set:
Digital module – channel strip “A” —> modulator module – channel strip “A”,
Digital module – channel strip “B” —> modulator module – channel strip “B”,
Digital module – channel strip “C” —> modulator module – channel strip “C”,
Digital module – channel strip “D” —> modulator module – channel strip “D”.
Note:
– Entries in the settings menus can be stored by pressing the
S
button.
—> You will be returned to the menu item
“Selecting the module / channel strip”.
