I/O grouping
I/O grouping is a matrix switcher feature that allows you to subdivide the front
panel control of the matrix into four smaller functional sub-switchers and limit tie
creation from the front panel only. Inputs and outputs can be assigned to one of
four groups or not assigned to any group.
Inputs and outputs that are assigned to a group can only be tied to other outputs
and inputs within the same group when you are creating ties on the front panel.
For example, a front panel operator cannot tie an input that is assigned to group 1
to an output that is assigned to group 2. Ungrouped inputs and outputs can be
switched to outputs and inputs in any group. Ties between groups (an input
in group 1 tied to an output in group 2) can be created under RS-232/RS-422 or
Ethernet control.
Suggested applications for the I/O grouping feature include:
• Segregating specifi c video formats to prevent an input in one video format
from being inadvertently applied to an output device that supports another
video format (fi gure 3-28).
• Segregating input and output devices that are in separate rooms.
• Isolating video from being displayed on specifi c output devices for
operational security reasons.
