2.4 Description
The modulator modules contain four modulators, which convert existing video
andaudiosignalsintoCCIRPALB/GsignalsintheC02…C69channel
range (HMM 470 / HMS 470)orOIRTPAL-D/Ksignalsinthechannelrange
R01…C69(HMM470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 HF output signals are sent through the HF output on
the modulator module to the output collector. The levels of the HF output sig-
nals 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
update 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. 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.de".
The modulator module is designed exclusively for use in the STC 160 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 STC 160.
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 STC 160.
 • Openthelockingdevice1in the direction of the arrow.

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.
