1. Press the Esc button to clear any input buttons, output buttons, or control
buttons that may be lit.
2. To enter I/O Group mode, press and hold the Input 1 and Output 1 buttons
simultaneously until the input and output buttons light to display the
ungrouped inputs and outputs. Release the buttons.
3. Press and release one of the Control buttons to select a group:
• Press the Enter button to select group 1.
• 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

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 serial port 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 (CrossPoint/Video (MAV Plus) 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.
