Typical connection of a two-way DiSEqC switch:
• Connect the cable from the LNB that is intended for channels from the
ASTRA satellite (or THOR) to the connector marked LNB 1 (A) on the
switch.
• Connect the cable from the HOTBIRD satellite (or SIRIUS) to the connec-
tor marked LNB 2 (B).
• Then, connect the antenna cable to the connector marked OUT on the
switch.
• Connect the other end of this cable to the ANTENNA input at the rear of
the Mediamaster.
For each LNB that you connect to the DiSEqC switch, the following
configuration has to be carried out.
As an example, the following section will describe how the LNB intended
for ASTRA will be configured for DiSEqC input 1 (A) on the switch and the LNB
intended for HOTBIRD will be configured for DiSEqC input 2 (B).
Switch port
Select the input for each LNB that will be connected. In this example, the
DiSEqC 1 input is selected first.
LNB type
Select the correct LNB type for your configuration, e.g. “Universal”.
LNB Offset voltage
If the cable from any of the LNB’s is very long, it might be necessary to in-
crease the voltage to these LNB’s by 0.5 V.
In most cases nothing needs to be altered here. Leave the default value as
“0 V”. If the switch does not change between horizontal and vertical polari-
sation, the voltage to an LNB can be increased later. Increase the voltage if
an LNB does not change polarisation.
Satellite
In this example, select ASTRA because its LNB is connected to the DiSEqC
1 input on the switch.
Predefined channel
Select one of the predefined channels and adjust the antenna until a TV pic-
ture from the predefined channel is visible on the screen.
• Press opt to view the predefined channel.
Repeat this procedure for the second DiSEqC port, but this time select 2 from
“Switch port” and HOTBIRD as the satellite.
When the configuration of both DiSEqC ports has been completed, press se-
lect. A confirmation that the DiSEqC ports have been configured will show
up. You can now start searching for channels.
• Press select to carry out the channel search procedure.
Please refer to the “Channel search” section on page 19.
