2.4 des Cription
The twin transmodulator module converts signals modulated according to DVB-
C/C2/T/T2 standard into two QAM modulated signals for feeding into a cable
network. The module has two digital RF inputs and one RF output.

RF OUT
The module is equipped with two channel strips. Using adequate CA modules
scrambled channels can be descrambled via tuner "A" and "B".
LEDs provide an indication of the input signal quality based on their colour and
indicate if the respective channel strip is switched on (LED illuminates) or off.

Indication
Data rate overflow (output)
The QAM modulated RF output signals are sent through the RF output of the
module to the output collector.
When the head-end station is switched on, the two-line LC display shows the
"SETUP" menu and the software version of the control unit. The head-end station output level can be adjusted in this menu.
The control of the module takes place via the control unit of the
tion. To operate the
QAM module
the software version of the control unit (headend station) must be "V 10" or higher. The operating software of the
module and the
head-end station can be updated using a PC and the software
head-end sta-
QAM
"BE-Flash" via the 9-pin D-SUB socket on the head-end station. You can find
the current operating software for the head-end station
the software "BE-Flash"
and the current assembly instructions
and the QAM module,
on the website
"www.triax.com".
The
QAM module
is designed exclusively for use in the CSE 2800 head-end
station.

2.5 how the tps module w o rks
After decoding the satellite signals, the demodulated data streams can be
accessed via the integrated TPS module. These data streams, also called transport streams, contain several stations with all their components (video, audio,
data and service information), which can be changed using the TPS module.
station fi lte r
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output data rate.
Ch a n ging the tr ansport s t ream and orgnet-id
The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of different channel strips, a new identification
must be allocated to the "new" transport streams to realise the channel search
of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.
Ch a n ging the nit
The transport stream contains data in the form of tables which the receivers
evaluate and require for convenient use. The TPS module can adjust the "Network Information Table" (NIT) to accommodate the new stations output data
(incl. LCN). The "NIT" contains data which is required by the set-top boxes
connected to the cable network for the automatic search feature.
3 installation
– Ensure the head-end station is mounted so it will not be able to vibrate.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– Before installing or changing a module, switch off the head-end station or
unplug the power cable from the mains power socket.
– Take measures to protect against ESD!
• Open the housing of the head-end station in accordance with the assembly
instructions for the CSE 2800.

3.1 retr o f itting a Ca module
The module is equipped with two common interfaces. This allows you to con-
nect two CA modules for various scrambling systems and service providers.
Scrambled channels can only be descrambled with a CA module suitable for
the scrambling system and the corresponding smart card. The smart card contains all the information for authorisation, descrambling and subscription.
– Check with the distributor or manufacturer of the CA modules to be used
to ensure that they are suitable for descrambling several channels.
– The hardware and software of this module have been thoroughly prepared
and tested.
– Any changes made by programme provider to the structures in the pro-
gramme data might impair or even prevent this function.
– When working with the CA modules, please read the corresponding oper-
ating manuals from the respective providers.
• Insert the smart card
1 into the CA module 2 so that the chip 3
on the
smart card faces the thicker side (top) of the CA module (fig. 1).
• Push the CA module 2 without canting into the guide rails 4 of the common interface 5 according to the following picture and contact it to the
common interface.

3.2 ins tal ling th e Qam module
–
Check that the plug contacts of the CA module are tightly seated in the
terminal strips on the
common
interface of the
QAM
module and make
sure there is reliable contact.
– When installing a module, make sure that it is inserted in one of the long,
numbered grooves in front of the contact strip on the board at the rear wall
of the housing.
– The shorter, non-numbered grooves without a contact strip on the board at
the rear wall of the housing are for add-on modules only.
• Open the housing of the head-end station in accordance with the assembly
instructions for the CSE 2800.
• Open the locking device 1 in the direction of the arrow (fig. 2).

• Insert the QAM module in grooves A of an open slot (with contact strip on
the board at the rear wall of the housing) and gently slide it into the headend station until it makes contact with the board on the rear wall (fig.3).
• After installing the QAM module close the locking device C in the direction
of the arrow (fig. 3). Ensure to get a well contact to spring B.

Switch on the channel strip (modulator) if necessary (page 16). For each channel strip, there is an status LED which indicates if the channel strip is switched
on.

• Balance the output levels of the channel strips and level them to the output
levels of the modulators of other modules used if the difference in level is ≥
1 dB (page 16).
5.2 not e s on l evel set ti ng
In order to prevent interference within the head-end station and the cable system, the output level of the module must be decreased by 10dB compared to
analogue modules at 64 QAM, and by 4 dB compared to analogue modules
at 256 QAM.
