8.1 About Unicable
The HDTV receiver smart CX20 allows for changing the receiving mode to
the unicable standard. This makes it possible - depending on the antenna
type - to connect up to eight independent receivers to only one main line.
For this, an own IF channel and a corresponding frequency should be set
for each receiver via the settings menu.
Allocation of channels and frequencies depends on the used LNBs and/or
multi-switches.
The data sheet and the technical documentation of your LNB and/or multi-
switch include an allocation table similar to the following table.
8.2 Allocation of IF channels and frequencies

 Enter the frequencies of your receiving system into the
last column of the table so that all relevant information
is quickly available. Rule of thumb: highest frequency 
shortest cable path.
