First time installation
DiSEqC 2 Input Switch
Select this alternative if your antenna system has two (2) LNB:s
and a 2-way DiSEqC switch.
In this case you must first connect the LNBs to an external
switch since there is only one antenna input on the Mediamaster.
Once installed the switch automatically selects the correct LNB
for the selected channel.
This external switch is better known as a DiSEqC switch. Since
the switch can be located close to the LNBs, you only need one
cable down to the Mediamaster.
Typical connection of a two-way DiSEqC switch:
• Connect the cable from the LNB intended for channels from
e.g. the Thor satellite to the connector marked LNB 1 (A for
mini DiSEqC) on the switch.
• Connect the cable from e.g. the Astra satellite to the connec-
tor marked LNB 2 (B for mini DiSEqC).
• Then, connect the antenna cable to the connector marked OUT
on the switch.
• Connect the other end of this cable to the ANTENNA input in
the rear of the Mediamaster.
For each LNB you connect to the DiSEqC switch, the fol-
lowing configuration has to be performed.
As an example we will describe how a LNB intended for Thor
will be configured to the DiSEqC input 1 (A) on the switch and a
LNB intended for Astra to DiSEqC input 2 (B).
Switch port
Here you select the input for each LNB that will be connected.
In this specific example, the Switch port 1 input will be selected
first.
LNB type
Select the correct LNB type for your configuration. Universal and
some LNBs with fixed frequencies can be selected using the
buttons.
LNB Offset Voltage
If the cable from any of the LNB's is very long, it might be nec-
essary to increase the voltage to these LNB's by 0.5 V.
In most cases nothing has to be altered here. Leave the default
value 0 V as it is. If the switch does not change between hori-
zontal and vertical polarisation, the voltage to a LNB can be in-
creased later. Increase the voltage only if an LNB does not change
polarisation.
Satellite
In this example, select Thor because its LNB is connected to the
DiSEqC 1 input on the switch.
