Extron Electronics MAV Plus series Large Scale User Guide - Manual (Page 56)

Operation, cont’d
CrossPoint 450 Plus and MAV Plus Switchers • Operation 3-24
Suggested applications for the I/O grouping feature include:
• Segregating specific video formats to prevent an input in one video format
from being inadvertently applied to an output device that supports another
video format
• Segregating input and output devices that are in separate rooms
• Isolating video so that it is not displayed on specific output devices for
operational security reasons
The I/O groups can be set on the front panel or by using either serial port or the
Ethernet port and either the SIS, Windows control program, or HTML pages (see
chapter 4, “Programmer’s Guide” and chapter 5, “Matrix Software”.
Create I/O groups on the front panel as follows:
1 . Press the Esc button to clear any front panel button indications that may be lit.
2 . 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.
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
input and output buttons.
5 . Press and release the RGBHV or Video button and the Audio button to
exit the I/O Group mode, or allow the I/O Group 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 the control of either serial port or the LAN port.
• 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 port 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) or Video (MAV Plus) button, the
Audio button, or both 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; it is not displayed by the Matrix Switchers Control
Program, HTML pages, or SIS commands; and it is not recommended.
• For I/O groups to have any function, at least two groups must be created.
