6.5.22 I/O Sharing (Option)
I/O sharing allows accessing any signal (input, master, PFL, monitoring, etc.)
of one system by another one within the same controller network. When con-
necting several systems, some additional things must be considered during
configuration:
  • Hard-wired (‘physical’) connections between the SCores (MADI, ADAT,
AES/EBU, or even analog) must be established.
  • Thesephysical connections must be defined within in the system, because
the system just needs to know which outputs and inputs are linked through
hard-wired connections. This is performed in the Configuration Tool of
the target system (see chapter 6.5.22.2).
  • Logical connections may either be defined as static (i.e. permanently
reserved for a certain signal) or dynamic (i.e. used by the system only as
long as required, which is more economical).
  • Asimplepoint-to-pointconfigurationcalled‘single-stepI/Osharing’(as
shown in the first example below) only needs physical connections to be
defined (see chapter 6.5.22.2).
  • In larger, ‘two-step I/Osharing’ configurations, Net inputs represent
objects in the star system that provide signals (e.g. Logical Input A) from
the source system to the target systems connected to the star system, as
shown in the second example below; Net inputs are defined according to
chapter 6.5.22.3.
  • Tomakethingseasier:-)differentsystemsmayactasstarsystemsimulta-
neously; in the second example below, Target System 3 also acts as a Star
System by providing the Logical Input B of the (pale) Source System 7
to Star System 2 – which, in this case, acts just as another Target System.
In other words: Each system may be Net Source, Star, and Net Consumer
system at the same time.
Glossary: Physical Connection Hard-wired connection between two SCores; for these, MADI, ADAT, AES/
EBU, or even analog connections may be used.
Logical Connection Connection between two SCores running on a hard-wired Physical Con-
nection; may be defined as static (permanently reserved) or dynamic (used
by the system only as long as required). For Net Inputs, only static Logical
Connections are allowed.
Logical Input The term Logical Input not only comprises the audio signal of this input but
also its signal processing parameters, such as EQ, filters, dynamics, etc.
Net Input Object on the Star System that is provided to other systems connected to the
Star System.
Net Source Object on the Source System that has specified a local source (e.g. input,
master, external PFL input, monitoring source, etc.).
Net Consumer Object on the Target system to which a mono or stereo signal must be assigned
(e.g. input, master, external PFL input, external monitoring source, etc.).
Net Consumer Active A Net Consumer is called active as long as it is using the allocated Net Source.
Consumer Type: is active if the corresponding Net Consumer is:
Net Logical Input
assigned to a channel strip, or selected as a monitoring
source, or assigned to a logical output via output routing
Net Ext. Monitoring
Source
selected as a monitoring source
Net Ext. PFL
switched to at least one PFL bus
Net Talkback
switched to at least one talkback destination
