It lists the signals of the various I/O cards and describes to which logical
inputs our outputs they will be assigned.
Please note that logical inputs and outputs are assigned to either the primary
or the secondary desk.
The Alias and Input Group columns also provide important information for
the A/B desk mode configuration.
Please note that a physical input used on both desks has to be mapped to two
different logical inputs, both of which will usually have the same Alias.
