3.3 CASCADING, CONTINUED
Video output from each slot in the first subrack, can be any of its 32 video inputs. Since
this output is connected to the cascade input of the second subrack, each slot of the
second subrack can, also view any of the 32 video inputs of the first subrack.
Video output devices (monitors etc.) connect to the output of the last video switching
subrack. In figure 3.2, only outputs from the second subrack would go to the monitors.
This method of increasing video inputs should only go through a maximum of three
video switching subracks in one cascade configuration. This ensures that high a quality
video signal is maintained.
Example Of Selecting Video Input 45
Using the cascading configuration (figure 3.2) above, the following diagram shows what
happens when video input 45 is selected onto monitor 2. For illustration purposes,
monitor 2 is connected to channel 2 (or slot 2).
If an operator selects video input 45 onto monitor 2, the video-switching module in
channel 2, of the second subrack, is instructed to connect the desired video input to its
video output.
