• 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.
• Presets can be created under RS-232/RS-422 or Ethernet control that tie
inputs and outputs across group boundaries. These presets
are
selectable
from the front panel.
• An input or output can be assigned to only one group. If you assign an
input or output to a group and that input or output is already assigned to a
different group, the older grouping is discarded in favor of the new grouping.
• You
can
break audio away from the video for a given input or output
(assigned to different groups) by isolating only video or only audio using the
front panel RGBHV and/or Audio buttons after you select
I/O Group
mode
(between steps
2
and
3
).
Audio breakaway across different groups
can be
confusing when you are
operating the front panel. Breakaway
is not displayed
by the Matrix
Switchers Control Program, HTML pages, or SIS commands; and is
not
recommended.
• For I/O groups to have any function, at least two groups must be created.
