Extron electronic MVX PLUS 128 manual 27 - I/O grouping of incompatible video formats

I/O grouping

I/O grouping is a matrix switcher feature that allows you to subdivide the front panel control of the matrix into four smaller functional sub-switchers and limit tie creation from the front panel only. Inputs and outputs can be assigned to one of four groups or not assigned to any group.

When you are creating ties on the front panel, inputs and outputs that are assigned to a group can be tied only to other outputs and inputs within the same group. For example, a front panel operator cannot tie an input that is assigned to group 1 to an output that is assigned to group 2. Ungrouped inputs and outputs can be switched to outputs and inputs in any group. 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.

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 (figure 3-27)

•Segregating input and output devices that are in separate rooms

•Isolating video from being displayed on specific output devices for operational security reasons
