Extron electronic 450 Plus manual Press and release one of the Control buttons to select a group

The I/O groups can be set up on the front panel or by using RS-232/RS-422 and Ethernet ports and either the SIS or the Windows control program (see chapter 4, SIS Programming and Control, and chapter 5, Matrix Software. Create I/O groups on the front panel as follows:

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 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/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.

•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.

•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.
