1 safety regulations
• The standards IEC/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!

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
electrical devices, such devices must be disposed of at a designated collection
facility. At the end of its service life, please take your device to one of these
public collection facilities for proper disposal.

2.4 desCription
The modulator modules contain four modulators, which convert existing CVBS
and audio signals into CCIR PAL B/G signals in the C 02 … C 69 channel
range (CGMM 480 / CGMS 480) or OIRT PAL-D/K signals in the channel
range R 01 … C 69 (CGMM 480 OIRT) via the AV interface.
The modulators are labelled (analogue to the channel strips) as "A", "B", "C"
and "D", and can be individually programmed. Four LEDs indicate if the re-
spective modulator is switched on (LED illuminates) or off.
The audio and video signals being fed in through the 26-pin socket of the mod-
ulator module are modulated onto the carrier frequencies (channels) which
have been selected. The RF output signals are sent through the RF output on
the modulator module to the output collector. The levels of the RF output signals
are adjustable by software.
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 total output level can be adjusted in this menu.
If the modulator modules are not detected by the head-end station you can up-
date the head-end station’s operating software via the head-end station’s 9-pin
D-Sub socket, using a PC or notebook and the "BE-Flash" software. To operate
the digital module the software version of the control unit (head-end station)
must be "V 10" or higher. You can find the current operating software for the
head-end station , the software "BE-Flash" and the current assembly instructions
on the website "www.triax.com".
The modulator module is designed exclusively for use in the CSE 2800 head-
end station.

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 installing the modulator module
– Always position modules which belong together next to each other. The
modulator module must be installed to the right of the digital module or an
add-on module.
– When installing a module, make sure that it is inserted in the long numbered
grooves in front of the contact strip on the board at the rear wall of the hous-
ing.
The shorter, not numbered grooves without 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.

—> Slots 1 (digital module) and 2 (modulator module) are shown in the
following figure. The open slot in between (without a contact strip
on the board at the rear wall of the housing) is intended for an add-
on module.

• Insert the modulator module in grooves A and B of an open slot on the
right hand side of the associated digital module or an add-on module.
• Gently slide the modulator 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.

• Using the AV cable C, connect the modulator module to the digital module
or to an add-on module if applicable.
• After programming, connect the modulator output D to one of the input
sockets E on the output collector.
• Close the locking device 1 in the direction of the arrow.
—> Ensure that the ground spring A gets contact to the locking device.

5.1 preparation
• Connect the test receiver to the RF output on the modulator module.
• Adjust the test receiver to the output channel of the channel strip to be set.
• Switch on the modulator if necessary. For each modulator, there is a green
LED which indicates if the modulator is switched on.
LED – Channel strip “A“
LED – Channel strip “B“
LED – Channel strip “C“
LED – Channel strip “D“
To use the CGMM 480 OIRT module the head-end station CSE 2800 must be set
to OIRT operation mode.
Therefore in the setup menu of the control unit
• press the button twice.
—> The “Setting the Standard” - “NORM” menu is activated.
• Switch to standard “PAL DK” using the button.
• Press the button.
—> The “Saving Data” - “MEMORY” menu is activated.
• Store the setting using the button.
—> Always all modulator modules are set.
Mixed operation is not possible!
To operate the CGMM 480 OIRT module the software version of the control unit
(head-end station) must be “V 9” or higher.
