7.5 Matrixes in parallel configuration
7.5.1 Description
Matrixes in parallel configuration refers to an installation where more than one matrix is present but there is
no exchange of video signals between matrixes. Each matrix supplies one monitor (or more) to each
operator. This type of installation configuration gives a good cost/efficiency rating when it is necessary to
connect more than 32 video inputs.
7.5.2 Example of parallel composite installation
In this example the installation has two parallel matrixes (P1 and P2) and two operators (K1 and K2)
ideally positioned in two different environments (e.g. two adjacent buildings).
Each matrix supplies a monitor to each operator: when the operator selects a video input this will switch
the video signal to the monitor connected to the interested matrix.
OUT 1 of all matrixes should reach operator K1; OUT 2 should reach operator K2.
Examples of video input selection:
Operator K1:
•
c7E
: selects camera 7 on the matrix to which the keyboard is connected (PAR1)
•
c107E
: selects camera 7 on parallel matrix 1 (corresponding to PAR1: since this is
the matrix to which keyboard K1 is connected, this is equivalent to the example above, although it is less
intuitive)
•
c207E
: selects camera 7 on parallel matrix 2 (PAR2)
Operator K2:
•
c19E
: selects camera 19 on the matrix to which the keyboard is connected (PAR2)
•
c219E
: selects camera 19 on parallel matrix 2 (corresponding to PAR2: since this is
the matrix to which keyboard K2 is connected, this is equivalent to the example above, although it is less
intuitive )
•
c119E
: selects camera 19 on parallel matrix 1 (PAR1)
