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. 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, you 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 (for example, an input in group 1 tied to an output in
group 2) can be created via SIS commands, the control software, or the web pages.
Figure 36 gives an example of input and output grouping of DVI Pro and HDMI devices on
a DXP.

Figure 36. I/O Grouping of Incompatible Video Formats
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
(see figure 36).
• Segregating input and output devices that are in separate rooms.
• Isolating video from being displayed on specific output devices for operational security
purposes.
I/O groups can be set up using the front panel, SIS commands via RS-232 or RS-422
control (see the “SIS Configuration and Control” section, starting on page 47), the
embedded web pages (see the “HTML Operation” section, starting on page 101), or
the Matrix Switchers Control Program via RS-232, RS-422, or IP control (see the “Matrix
Software” section starting on page 70). To set up I/O groups using the front panel:
1. Press the Esc button to clear any input, output, or control buttons that may be lit.
2. To enter I/O group mode, press and hold the Input 1 and Output 1 buttons
simultaneously until the buttons light to indicate the ungrouped inputs and outputs,
then release the buttons.
