1 notes about safety and hazards
• Observe the relevant VDE regulations.
• If the power cord needs to be replaced, only use an OEM power cord (EMV!).
• Only replace fuses with fuses of the same type, and which also have the
same cut-off characteristics.
• The standards IEC/EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must
be observed, especially concerning equipotential bonding and earthing .
• Observe the relevant country-specific standards, regulations and guidelines
on the installation and operation of antenna systems.
• Before starting installation or service work disconnect the receiving system
from mains.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• For a complete disconnection from the mains, the mains plug must be pulled
out of the mains socket. Ensure that the mains plug can be pulled out without
difficulties.
• The head-end station should only be installed in a room where the permissi-
ble ambient temperature range (0 °C and +50 °C ) can be maintained, even
during fluctuations in climatic conditions.
• Make sure there is a minimum space at wall mounting and stand mounting of
20 cm on either side and 50 cm above.
• To avoid too strong interacted heating of the head-end stations it is not
admissible to mount them one upon the other without using thermic precau-
tions (e.g. permanently air recirculation, ventilation, heat deflectors etc.).
• Install the head-end station
- in a dry, dust-free environment
- in such a manner that it is protected from moisture, fumes, splashing wa-
ter and dampness
- where it is protected from direct exposure to sunlight
- on a vibration-free wall or floor construction
- not within the immediate vicinity of heat sources
• In case of the formation of condensation wait until the system is completely
dried.
• Ensure that the head-end station is adequately ventilated.
• Do not cover the ventilation openings!
• Do not install the head end in cabinets or recesses which are not ventilated.
• If additional fans are to be used to circulate the air, ensure that the system will
be shut down (disconnected from mains) should any one of the fans fail.
• Do not place any vessels containing liquids on the head-end station.

- 5 - STC 1200
• Do not place anything on the head-end station which could initiate fires
(e.g. candles).
• Due to the risk of fires caused by lightning strikes, we recommend that all
mechanical parts (e.g. distributor, equipotential bonding rail, etc.) be mounted
on a non-combustible base. Wood panelling, wooden beams, plastic covered
panels and plastic panels are all examples of combustible bases.
• Avoid short circuits!
• To ensure electromagnetic compatibility, make sure all connections are tight
and that the covers are screwed on securely.
• No liability is accepted for damage caused by faulty connections or inap-
propriate handling of the device.
• You can obtain additional information from the "Planning handbook" bro-
chure which can be found on the website "http://www.mygss.eu" under
the " Miscellaneous" category.

2.5 desCription
The head-end station has a modular structure and can hold up to Standard
cassettes. You can find a list of the current Standard cassettes at the website
"www.mygss.eu". This head-end station is designed exclusively for use with
cassettes of the Standard marketing programme. The various expansion op-
tions for the head-end station allow for the installation of a wide range of
broadband cable systems.
Each of the three integrated SAT IF input distributors has two SAT IF inputs.
You can use them to distribute two reception levels over 4 or 6 outputs. Using
the loop-through output enables you to distribute reception level 1 over the 10
outputs for each SAT IF input distributor. The F sockets of both reception levels
are coloured.
Basic signal pattern:
9-12 dB 9-14 dB
8 dB
Unused loop-through outputs must be terminated with the resistors supplied.
The power supply in the head-end station is designed to supply power to
components (e.g. LNBs) connected upstream. These are supplied via the SAT
IF input distributors’ input sockets with operating voltage (+18 V) at a total
current of max. 1 A.
In addition, the head-end station’s power supply unit can be used to supply
peripheral devices with voltage (+12 V / max. 1 A, with an external fuse).
The cassettes’ HF output signals are accumulated in a programmable HF out-
put collector and then directed to the HF output and to the test output via the
downstream hybrid amplifier.
When the head-end station is shipped from the factory, the default setting for
the HF output level of the output collector is -3 dB. You can use the software of
the control unit to program the master output level of the head-end station.
The software version of the control unit appears on the two-line LC display
after switching on the head-end station. If the inner temperature of the head-
end station exceeds the permissible temperature of 65 °C when operating, a
message appears in the display instead of the standby menu. This message
contains the maximum measured temperature and the number of the head-end

- 9 - STC 1200
station. The display also supports dialogue guidance when programming the
head-end station. Use the buttons of the control unit to program the head-end
station. You can also use the PSW 1000 software and the HRCU 8 / RCU 1
management unit to program the head-end station.
The RS 232 interface of the control unit enables you to use a PC or a note-
book and the "BE-Flash" software to update the operating software of the
control unit. You can find the current operating software for the control unit,
the software "BE-Flash" and the current assembly instructions on the website
"www.mygss.eu".

4.1 emC reGulations (el ec t romag netic Co mpati bi l it y)
To comply with the current EMC regulations, it is necessary to connect the lines
leading in and out of the head-end station (e.g. Cinch, HF) using standard
cable terminals.
Fig. 7
• According to figure 8 insert the required number of standard cable termi-
nals in the openings provided in the front of the head-end station (fig. 2 5,
page10).
Tighten the nuts on the cable terminals until the teeth on the lock washers have
penetrated the exterior coating and a good connection is made between the
housing and the cable terminals.

mountinG in a Cabinet
In cabinets a circular aeration (e.g. by means of ventilators) is to be ensured.
In addition it is necessary to permanently control the ambient temperature of
max. +50 °C by means of thermo elements. If the ambient temperature inside
the cabinet exceeds +50 °C, a thermo switch with reclose inhibition must au-
tomatically disconnect the system from the mains power supply.
• Position the head-end station in the cabinet so that the distance to the cabi-
net walls on either side is minimum 20 cm. Ensure minimum 50 cm of free
space above the head-end station as well.
