1 Description
The X-QAM twin x – cards are used for processing of two
QPSK – modulated SAT – IF – signals into two QAM –
modulated adjacent channels in the frequency range
from 47 to 862 MHz. The signal processing of the X-QAM
twin x – modules is realized with the Direct Digital ® -
technology. The two output channels can be switched
on and off separately from one another. Each board has
a level control for level matching of the individual plug-in
boards to the same output level via KC 3 or HE program-
ming software.
Except the X-QAM twin 3, which converts the input sig-
nals quasi-transparent, all X-QAM twin x – cards are
equipped with the possibility to program PID filters and
PID remapping as well as an optional NIT processing.
There is also implemented an optional editing function for
the Operator – ID.
If the output data ratio is undervalued, all X-QAM twin x –
cards adapt the data ratio on the minimum requested
value.
A further feature is the automatically level adjustment, if
different kinds of modulation are chosen, independent
from the kind of modulation (chapter “Level adjustment”).
Please note:
Authorized and qualified personnel only, is allowed
to change the plug-in modules. Before this, the ope-
rating instructions, and especially the security advi-
ses, of the V16 base unit have to be read and
followed. All works have to be done according to the
security standards DIN VDE 0701, part 1 and 200.

3 Programming with the HE programming
software
3.1 Pre – configuration of the HE programming software
The X-QAM twin x – cards can be programmed via HE pro-
gramming software after plugging them into the base unit.
The activating of PID filter, NIT processing or the editing of
the Operator – ID can only be done with the programming
software! If it is not possible to choose the X-QAM twin x –
card from the list in the „Overview of the base unit“, you
should check the settings at “Options” and “Favoured plug-in
cards”. The card must be activated as below, to appear on
the list in the „Overview of the base unit“.
After reading out the base unit, the X-QAM twin x – card
appears on the used slot of the base unit.
Please note: Requested software version

X-8 Basis twin: x.22
V16: x.22
Programming software: 5.00

Cabling of the X-QAM twin x
The X-QAM twin x – cards can be operated with bridged
input signals. This means the SAT – IF is taken from the
loop-through output of tuner A to the input of tuner B.
SAT – IF bridged from tuner A to tuner B
Tuner A and Tuner B connected to SAT – IF separately
SAT – IF input
Tuner B Tuner A
SAT – IF output

3.2 Activating the NIT processing
The NIT processing can only be activated via HE pro-
gramming software. Therefore, the option “Generate
CABLE – NIT” has to be chosen (“Design” →“Network
NIT”)
The X-QAM twin 3 has no possibility to create the NIT,
the input NIT is transferred to the output. If you activate
the NIT processing, the X-QAM twin5and X-QAM twin6
create the NIT in each channel fed by this type of card.
This NIT includes every QAM channel of the local net-
work. At “NIT – information” the parameters of the chosen
QAM bouquet are displayed.
Those information are TS-ID, ONID, output frequency,
data ratio and type of modulation.
3.3 Programming the card parameters
In the overview of the base unit, the output channels of
the X-QAM twin x – cards are chosen at “RF parameters”.
In those channels, the former QPSK bouquets are fed in
as QAM bouquets. The chosen channel is always chan-
nel A. Channel B is automatically determined as adjacent
channel of channel A.
If you now click on the “Details” button, a window opens
for configuring the card details. Here you can make the
relevant settings for the operation.
3 Programming with HE programming software 3 Programming with HE programming software
6

At the area „Input parameters“ those data are displayed,
which are stored in the SAT data base for the concerned
transponder. At the area “RF output parameters” all relevant
settings for the output signal can be done. You can activate
or deactivate the output signal, determine the output chan-
nel grid (2, 4, 6 or 8 MHz), invert the spectrum and adapt
the output data ratio (1.725; 3.450; 5.175 and 6.900 MS/s).
If the output data ratio is undervalued, all X-QAM twin x –
cards adapt the data ratio on the minimum requested value.
In the output you can set the type of modulation. The view
of the parameters of the X-QAM twin 3 differs in the
nonexistent “Options of channel A + B” – window.
3.4 Testing the input signal quality
If you use the button “Check signal
quality”, the C/N and the Bit error
ratio of the input signal of the card
will be displayed.
3.5 Level adjustment
The level adjustment of the X-QAM twin x– card can also
be done via HE-programming software. For this you just
have to click on “Level control“ in the window “Parame-
ters of the Plug-in card”.
The following window appears:
First of all you should push the button „Parameter read“,
to read out the already programmed state of attenuation.
The next step is
the correction of
the attenuation in
0.5 dB – steps in
a range between
0 and 15.5 dB.
To store the
changed values
press „Parame-
ter write“.

3.7 PID remapping
The X-QAM twin 5 and X-QAM twin 6 offer the option to
remap PIDs, this means to change the “name” of the PID.
The PIDs have to be inserted hexadecimal. If you type in
a “0000”, the PID remapping is deactivated.
3.8 Error messages
If errors appear during the operation of the plug-in card,
the error code is displayed in the field “card status”
If the output level of the adjacent channels is different,
each level can be adapted on the IF in a range between
-1 dB to +1 dB (0.1 dB – steps). This function is suppor-
ted only via HE programming software and not possible
with the KC 3.
If different types of modulation are chosen for channel A
and B, an automatically level adjustment is made for
each channel separately, based on 90 dBµV for QAM 64.
Examples:
Channel A: Channel B:
QAM 64; level 90 dBµV →QAM 128; level 93 dBµV
Channel A: Channel B:
QAM 64; level 90 dBµV →QAM 256; level 96 dBµV
The level will also be adapted automatically if the band-
width of the output signal has been changed.
3.6 Setting the PID filter
The setting of PID filter is not supported by the X-QAM
twin 3. This function is only possible with the X-QAM twin
5 and X-QAM twin 6. The setting of the PID filter makes
possible the blocking of up to four services from the pro-
cessed transport stream. You can filter out for example
Audio or Video PIDs of some programs. If you filter out a
Video PID, the Set-Top-Box will find the program, but it
can not show the picture. In the field “Transport Stream
Information” the TS-ID and ON-ID of the chosen trans-
ponder is displayed.
