I/O grouping
I/O grouping is a matrix switcher feature that allows you to subdivide the front
panel controls of the matrix into four smaller functional sub-switchers and limit tie
creation using the front panel only. Inputs and outputs can be assigned to one of
four groups or not assigned to any group.
When you are creating ties on the front panel, inputs and outputs that are assigned
to a group can be tied only to other outputs and inputs within the same group. 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 specific video formats to prevent an input in one video format
from being inadvertently applied to an output device that supports another
videoformat(gure3-28)
• Segregating input and output devices that are in separate rooms
• Segregating input and output devices on which you are distributing audio on
the audio/RS-232 wire pair from those on which you are distributing RS-232
signals.
• Isolating video from being displayed on specific output devices for
operational security reasons
