The I/O groups can be set up on the front panel or by using RS-232/RS-422 and
LAN ports and either the SIS or the Windows control program (see chapter 4,
“Programmer’s Guide”, and chapter 5, “Matrix Software”). Create I/O groups on
the front panel as follows:
N
I/O groups are protected when front panel lock mode 2 is selected. You can view
the groups in lock mode 2, but you cannot change them from the front panel. See
“Setting the front panel Locks (
Executive modes)” on page 3-46.
1 . Press the Esc button to clear any input buttons, output buttons, or control

• Press the Preset button to select group 2.
• Press the View button to select group 3.
• Press the Esc button to select group 4.
4 . Select the desired input(s) and output(s) to assign to the group by pressing the
input and output buttons.
5 . Press and release the Video and Audio button to exit the I/O Group mode, or
allow the mode to time out after approximately 30 seconds.
N • 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.
• Ties that were created before I/O groups were created remain valid, even if
they include inputs and outputs in different groups.
• 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 Video 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 grouping is not displayed by the
Matrix Switchers Control Program, HTML pages, or SIS commands; and is
not recommended (breakaway ties, once created, are displayed).
• For I/O groups to have any function, at least two groups must be created.
