1 Function
The GigaSwitch 11/20 multiswitch is used to supply between 20 and 120 receiving participants with a satellite intermediate frequency as well as with a terrestrial signal.
The following combinations can be distributed by this piece of equipment::
> two full bands of the Astra satellite Low and High Band plus the EUTELSAT Low and
High Band;
or
> four satellites of your choice with two polarisation planes each;
or
> eight individually selected polarisation planes.
> In addition, FM, VHF and UHF inputs are available for distribution of terrestrial sig-
nals.
The GigaSwitches comply fully with the Astra IES concept (integrated reception system).
The star-form distribution provided by the GigaSwitch 11/20 multiswitch provides the advantage of permitting reception of other satellite services to receiving parties without any additional installation.

2 Safety Hints
For your own protection, you should read the safety hints carefully before installing the
GigaSwitch multiswitch. The manufacturer accepts no responsibility for damage caused by
non-observance of the safety hints, or by inappropriate handling.
> The components must be mounted in dry rooms on flat, non-flammable surfaces.
> Air circulation slots on the components must permit unimpeded circulation.
> The installation must be carried out while the unit is not connected to the power
mains.
> The multiswitch must be connected to ground (earthed).
> The antenna installation must comply with local regulations relating to lightning pro-
tection.
> The relevant EU standards as well as VDE or national regulations relating to electrical
safety must be observed.
> National regulations relating to broadcast reception equipment must be observed.
> Never open the unit cover, as you may be subject to an electrical shock!!!
> If it becomes necessary to open the unit, this should only be carried out by trained
personnel.
In the following cases, you should disconnect the unit from the power mains, and call an
expert/trained personnel:
> When the unit has been subject to extreme humidity, or when liquid has entered the
unit;
> When the unit malfunctions;
> If the unit shows severe external damage.
3 Introducing the components
3.1 GigaSwitch 11/20G (Part No. 0000/3229)
The GigaSwitch 11/20G is the basic unit in the multiswitch range. The GigaSwitch 11/20G
provides distribution of the Intermediate Frequency signal to 20 participants, including provision of power to the LNBs. In larger installations it also provides the power for the cascade
multiswitch GigaSwitch 11/20K, for the distributor 9V and for the intermediate amplifier 9Z.
When installing a cascade system of several components, please ensure that the maximum
power voltage is not exceeded (see technical specifications).
3.2 GigaSwitch 11/20K (Part No. 0000/3228)
The GigaSwitch 11/20K is the cascade unit in the multiswitch range. This unit receives its
power supply from the basic unit GigaSwitch 11/20G. The GigaSwitch 11/20K unit can thus
only be used in conjunction with the basic unit. The GigaSwitch 11/20K is inserted between
the LNBs and the basic unit, with each additional 11/20K unit providing connections for 20
participants.
The function of the cascade is to distribute the eight polarisation planes as well as the terrestrial signal further along the main connection, and to provide up to 20 participants with independent access to the selected band.

3.3 Intermediate Amplifier 9Z (Part No. 000/3231)
The intermediate amplifier 9z has been designed to compensate for the damping effect of
25m of multimedia cable, or of 40m of CoaxSat 2150 cable, when used to transmit satellite
signals. The amplification of terrestrial signals can be adjusted.
3.4 Distributor 9V
This is used to achieve a three-way split of main-line connections, while providing a high
degree of insulation.
A cascade switch can be connected directly to the lower outputs. The outputs at the front
can be used to feed a further 2 cascade units, using up to 20m of multimedia cable.
One or more distributors can thus be used to assemble fairly large installations.
> Where the damping of the main line connection is less than 5 dB (at 2150 MHz), no
intermediate amplifier is required. The intermediate amplifier 9Z is only required
where higher damping levels are present.
4 Settings
4.1 Switchable outputs for each party, 22 kHz or DiSEqC control
On the side panels of the unit, above each of the uppermost participant output connections
you will find a switch with which you may set the reaction of the specific output connector
with regard to 22 kHz or DiSEqC control. These switches relate exclusively to parties 1 and
2, as well as to parties 11 and 12. They are provided for receivers that do not provide a
DiSEqC control facility. For such receivers you must select individually the inputs you wish to
address with the 22 kHz control.
a) Position A/B
If the switch is in this position, the Low Band of Position A will be received without the 22
kHz control signal, and the Low Band of Position B will be received with the aid of the 22
kHz control signal.
b) Band Low/High
If the switch is in this position, the Low Band of Position A will be received without the 22
kHz control signal, and the High Band of Position B will be received with the aid of the 22
kHz control signal.
