Operation, cont’d

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:

NI/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
	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 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.
