Rotary Switch
The rotary switch is the central element of the multi-switch. It sets the operation mode
and functionality.
The rotary switch is divided into the left and the right half:
If the rotary switch is set to a mode on the left,
Kathrein Power Saving
is off , i.e. the LNB is powered
permanently.
If the rotary switch is set to a mode on the right,
Kathrein Power Saving
is active and the LNB is
switched on only if at least one receiver in the
system is active.
In the factory default setting,
Kathrein Power Saving
is
turned off .
Input Frequency Ranges of the Multi-Switch
Depending on the connected LNB, there are two input frequency ranges:
Universal
In case of a universal LNB, the four levels (VL, VH, HL, HH) of the LNB are
connected to the inputs of the multi-switch. The LNB supply voltage is
provided at the HL input.
Wideband
A wideband LNB has an extended frequency range (300 – 2350 MHz),
therefore, only two inputs per satellite are necessary. In combination with
two wideband LNBs, the multi-switch can operate two satellite positions.
The VL and HL inputs are assigned to position A, the VH and HH inputs to
position B. If only one wideband LNB is connected to the multi-switch, it is
necessary to use the VL and HL inputs.
In addition, an LNB supply voltage is provided at the HH input in all posi-
tions marked in black.
If only one satellite position is used, it is necessary to terminate all the
inputs which are not in use with DC-decoupled resistors (e.g. EMK 05).
The settings of the rotary switch are eff ective only if both subscriber outputs are
powered off .
►
Unscrew
both
connecting cables to interrupt the power supply.
Changes in the confi guration during operation can lead to undesirable confi gurations
and malfunction.
►
Do not alter the confi guration during operation.
Multi-switches without
Kathrein Power Saving
do not give signalling to the end multi-
switch. For permanent powering of the LNB, the rotary switch must be turned to the
left side.
