Operation, cont'd
The I/O groups can be set up on the front panel or by using serial port and
Ethernet 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:
1.
2.
3.
4.
5.
3-22 CrossPoint 450 Plus and MAV Plus Switchers • Operation
I/O groups are protected when front panel lock mode 2 is selected. You can
view the groups in lock mode 2, but not change them from the front panel.
Press the Esc button to clear any input buttons, output buttons, or control
buttons that may be lit.
To enter I/O Group mode, press and hold the Input 1 and Output 1 buttons
until the input and output buttons light to display the ungrouped inputs and
outputs.
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.
Select the desired input(s) and output(s) to assign to the group by pressing the
input and output buttons.
Press and release the RGBHV/Video and Audio button to exit the I/O Group
mode, or allow the mode to time out after approximately 30 seconds.
• Ties between groups (an input in group 1 tied to an output in group 2)
can be created under serial port or Ethernet control.
• 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.
• Audio can be broken 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 450 Plus)/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
operating the front panel; 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.
