A Common Interface slot is available. A conditional
access module (CAM) can be inserted to
descramble output services.
The multiplexer can demodulate up to three
DVBS or DVBS2 signals from one or two satellite
IF inputs. The user selects which services will
be transmodulated in each of the two available
outputs. Two transport stream are created, which
are then modulated in QAM (564401) or COFDM
To congure the multiplexer operating parameters
(input frequency, output channel, modulation
format and adaptation of services) the universal
programming unit (ref. 7234) or theTSuite software
can be used.

REMARKS
• The power supply can power up to a maximum of 7 modules with CAM, and being active only 2 LNB feeds of the assembly of seven multiplexer.
• When a CAM is inserted, it is assumed that the multiplexer’ consumption increases about an average of 70 mA (since CAM consumptions in the market
can vary between 20 & 100 mA). Each LNB feed activated increases the multiplexer’ consumption about 250 mA (also depending on the LNB model).
• The two PSU power outputs must be used in order to balance their consumptions in a chassis, therefore whenever the demand of power exceeds 4A
(max. current for each output), it is necessary to distribute it between the two powering outputs of the PSU (for example: 4+3 modules; 3+4 modules).
24V: OK
0V: Overload or short circuit

5.1 Standard menu
5.1.a Input menu
The multiplexer consists of 3 demodulator
(called A, Band Cin the menus). The signal to
be demodulated comes from one of the two
F connectors, since the second input can be
congured either as a loop-through of the rst
one, or as an independent input (see menu 5.2b).
In the latter case, demodulator Areceives signal
from connector 1 while demodulator Band C
receive signal from the second connector. The
module is able to provide power voltage to 2 LNB
through their input connectors whenever they
are congured as independent inputs, as well as a
selection of satellite using DISEqC commands.
The rst standard menu allows to select the input
frequency and the symbol rate of each one of the
3 input channels.

• Identier of the input to which the service
belongs: A, B or C.
• Status of the encryption of the service, for
both input and output of the module. When
the service is set to ON/OFF, only is displayed
the input status. When the service is congured
as DCY, it is displayed its status before and after
passing through the CAM.
Additionally, on the upper right corner of the
window it is indicated the status of the service on
the input (encoded or plain), for those services
set to ON and DCY:
Scrambled service in the input: a) if set to
OFF, it does not pass to the output; b) if
set to ON, it exits without going through
the CAM.
Free service in the input: a) if set to OFF,
it does not pass to the output; b) if set to

• Service’s order within the list, and total number
of services found from all inputs (see gure,
where 7/56 indicates that it is the index 7 of a list
containing 56 services).
• Statistics. A value indicating the occupation
of this service at the output as well as the
percentage that remains free.
It is displayed as N/M (23/50 in the gure), where:
»N indicates the capacity needed at the output
to transport this service. If this service is ON,
it indicates the percentage of the output
occupied by the service, this is, percentage of
the whole bit rate occupied by this service if it
is enabled to pass through.
»Mindicates the percentage of the output that
still remains available to transport additional
services. This value is updated if you change
the status of a service (when switching to
ON, the output’s occupation is subtracted
automatically - switching to OFF it is added)
thus giving a good estimate of available
capacity before saving the conguration. It is
said an estimate because its value is increased
or decreased according to what would occupy
the complete service (without considering
PID ltering, even when selected previously).
Once saved the conguration, this value will

MUX DVBS2_QAM/COFDM CI Twin 18
become the actual value to take into account,
which may vary slightly from the estimate.
Note: When the number of services exceeds 100, it is
displayed the list of services and occupation
alternately, due to the limited space on the
programming unit.
• Service name
• Service ltering status. Choices are OFF, ON1,
ON2, DCY1, DCY2.
»ON1, ON2 : The service passes straight forward
to the output 1 or 2, without changes.
»OFF The service is not allowed to go through
to the output.
»DCY The service goes through to the output
1 or 2 and also request its unscrambling
to the module of conditional access if it
is available. A sign of admiration (!) will
appear in this condition, when for the
position in which the CAM is situated
is impossible to decrypt it. If the CAM is
located at the output 1 DCY2 option will
not be allowed.
There are two ways to move from one service to
another:
I. First, by short presses on the key, move the
cursor to the service name; then use keys
and to move up/down among services.
When using the key from the last service of
one of the inputs, it is automatically displayed

(more than 2 sec). This option shows the list of PID
belonging to the service that was displayed on the
standard menu.
Be aware that it should be used carefully and may
need to know the characteristics of the input
transport stream for proper conguration.
This is because the PIDs of a service are subject
to changes, and if this happens the values set in
this menu may no longer be valid and therefore
unwanted behaviors can occur at the output.
Come back to the service menu by a long press on
key.
5.1.e.1 PIDs menu
To access this menu, within the service menu make
a long press on key. Make again a long press on
key to return to service menu.
Choose a service and then select the action to be
carried out with its PIDs.
The main use of this menu is to remove an audio
streaming (for those services that have more than
one audio) or other service information (teletext,
private data, ...) so that you can reduce the output
occupation.
In the case of having a CAM module, it is possible
to reduced the capacity used, and allowing
sometimes increasing the number of services that
can be unscrambled:

The available information in this menu is the
following:
• Identier of the input from which comes the
service (A, B, C).
• Identier of the service to be congured (SID
Service id).
• PID index and total number of them available
in the service (in above examples: 1/5 and 3/5).
• PID identier (in above examples: 160 and 162).

• Description of the PID function:
»Video Service video streaming. It displayed
on the screen with the word video.
»Audio Audio streaming. It displayed on
the screen with a letter followed by
3 characters that provide additional
information about this audio. In
most of the cases they identify the
language, but not always is the case.
As an example: “spa” would mean
Spanish language.
»Other This way are displayed the PIDs not
corresponding to video and audio.
» In some PIDs is displayed an asterisk () sign.
This means that this PID contains information
about PCRs (Program Clock Reference).
• PID ltering status: ON, OFF, DCY.
Not all options are always available. If a service is
set OFF, all its PIDs are OFF and therefore it will
not possible modify their values.
If a service is set ON, it will be possible select PID
ltering ON and OFF, but never DCY.
DCY PID ltering option is available only for
those services set DCY.
PIDs marked with cannot be set OFF since
they contain PCR information of the service
which is indispensable for the correct decoding
of the output.
»ON It passes to the output without any
request of unscrambling to the CAM
module.
»OFF It is not allowed to pass to the output
»DCY It passes to the output and requests
unscrambling to the CAM module, if
available.
5.1.f Measure menu 1
This menu provides an indication of the input
signal quality by estimating both C/N (dB) and
Link margin (dB).

5.1.g Measure menu 2
This menu shows messages related to adaptation
and deleting of services congured in the SERVICES
menu for each of the two outputs.
If all input are unlocked, no message is displayed.
Possible messages to be displayed are the
following:
• Occupation
Occurs when the adaptation is being carried out
without error, and shows the user the percentage
of bit rate that is occupying at the output.
It also shows the peak reached, which
can be reset by pressing on key.
Occupancy rates shown on this screen are
always actual percentages; ie, only those that are
the result of the last recording made by the user.
In no case it is considered the value of occupation
“estimated” from changes of conguration not
saved, as done in section 5.1.e Service Menu.

• Overow
This message is displayed when it is detected
that the services selected exceed the bit rate
available at the output. Therefore, the user must
delete some of selected services in order to
ensure a correct operation.
Occupancy values beyond 82% are not
recommended. This is so since the occupancy
indication is an instant measure. If this value
is exceeded due to the variability of the input
transport stream, it could cause occasional
overows which would degrade the quality of
the output image.
This is a read only menu.
