2.4 Description  
The modulator modules contain four modulators, which convert existing video  
and audio signals into PAL B/G signals in the C 02 … C 69 channel range 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 respec-  
tive modulator is switched on (LED illuminates) or off.  
The audio and video signals being fed in through the 26-pin socket of the  
modulator module are modulated onto the carrier frequencies (channels) which  
have been selected. The HF output signals are sent through the HF output on the  
modulator module to the output collector. The levels of the HF 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 station  
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  
- 4 -  
 
D-Sub socket, using a PC or notebook and the “BE-Flash” software. 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.gss.tv.  
The modules are designed exclusively for use in the STC 160 head-end station.

Installation  
Caution  
– 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 precautions to prevent static discharge when working on the device!  
Open the housing of the head-end station according to the instructions in the  
STC 160 installation manual.  
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 num-  
bered grooves in front of the contact strip on the board at the rear wall  
of the housing.  
The shorter, not numbered grooves without contact strip on the board at  
the rear wall of the housing are for add-on modules only.  
- 5 -  
 
Open the housing of the head-end station in accordance with the assembly  
instructions for the STC 160.  
• Open the locking device 1 in the direction of the arrow (fig. 1).  
Fig. 1  
—> Slots 1 (digital module) and 2 (modulator module) are shown in fig-  
ure 2. 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 (fig. 2) 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.

!
"
Fig. 3  
• 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 sock-  
ets E on the output collector.  
• Close the locking device 1 in the direction of the arrow.

Programming  
5.1 Preparation  
• Connect the test receiver to the HF 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“  
The process of programming the HMM 470 and HMS 470 modules is the  
same, with one exception. The programming process for the HMM 470  
module is described in section 5.3. Please see sections 5.4 and 5.3 to pro-  
gramme the HMS 470 module.

Final procedures  
After installing the head-end station, upgrading accessories or installing  
modules it is necessary to tighten all cable connections, F terminals and cov-  
er screws in order to maintain compliance with current EMC regulations.  
• Securely tighten the cable connections (F connectors) using an open-ended  
spanner (spanner gap 11 mm).  
• After programming, connect the modulator output D to one of the input sock-  
ets E of the output collector (page 7, fig. 3).  
• Test the output level of the output collector according to the STC 160 assembly  
instructions and set the output level required for the cable system.  
• Mount the base plate and the front cover (see STC 160 assembly instruc-  
tions).
