1 safety regulations
• The standards EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be
observed.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing should be carried out by authorised
electricians.
• Switch off the operating voltage of the system before beginning with assem-
bly or service work.
• Avoid short circuits!
• Observe the relevant standards, regulations and guidelines on the installa-
tion and operation of antenna systems.
• To ensure electromagnetic compatibility, make sure all connections are tight
and the covers are screwed on securely.
• No liability is accepted for damage caused by faulty connections or inap-
propriate handling of the device.
Check the head-end station CSE 2800 according to the safety instructions
listed in their assembly instruction.
Take precautions to prevent static discharge when working on the device!
Electronic devices should never be disposed of in the household rubbish. In
accordance with directive 2002/96/EC of the European Parliament and the
European Council from January 27, 2003 which addresses old electronic and

2.4 desCription
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.

Combiner
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.
LED indicator Indication
Green Signal quality is good
Orange Signal quality is poor
Red No signal
Red<– >Green Data rate overflow (output)
Off Channel strip (modulator) off
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 sta-
tion output level can be adjusted in this menu.
The control of the module takes place via the control unit of the head-end sta-
tion. To operate the QAM module the software version of the control unit (head-
end station) must be "V 10" or higher. The operating software of the QAM
module and the head-end station can be updated using a PC and the software
"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 and the QAM module,
the software "BE-Flash" and the current assembly instructions 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 works
After decoding the satellite signals, the demodulated data streams can be
accessed via the integrated TPS module. These data streams, also called trans-
port streams, contain several stations with all their components (video, audio,
data and service information), which can be changed using the TPS module.
station filter
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output data rate.
Changing the transport stream 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.
Changing 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 "Net-
work 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 retrofitting 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 con-
tains 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 com-
mon interface 5 according to the following picture and contact it to the
common interface.

3.2 installing the 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).

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 head-
end 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.

• Connect the RF inputs E (input "A") and F (input "B") on the QAM mod-
ule (fig. 4) to corresponding signal sources via the preinstalled Fterminals
in the rear wall of the head-end station through the cable inlets H using RF
cables made on-site.
• After programming, connect the modulator output G to one of the input
sockets I of a retrofitted output collector.
• Connect the head-end station to the mains power supply.
