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.

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

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 3-27)

Segregating input and output devices that are in separate rooms

Isolating video from being displayed on specifi c output devices for
operational security reasons
