I/O grouping
I/O grouping is an RS-232/RS-422 controlled feature that allows you to subdivide
the front panel control of the matrix into up to four smaller functional sub-
switchers. Inputs and outputs can be assigned to one of four groups (figure 3-4) or
not assigned to any group. Once assigned to a group, inputs and outputs can only
be tied within that group from the front panel. 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.

Figure 3-4 — I/O grouping of compatible twisted pair
transmitter/receiver pairs
The I/O groups can be set up only by using the RS-232/RS-422 port and either the
SIS or the Windows control program (see chapter 4, Programmer’s Guide, and
chapter 5, Matrix Software. Ties between groups (an input in group 1 tied to an
output in group 2) can be created under RS-232/RS-422 control. Presets can also be
created under RS-232/RS-422 control that tie inputs and outputs across group
boundaries. These presets are selectable from the front panel.
Suggested applications for the I/O grouping feature include:
Segregating specific twisted pair transmitter and receiver formats to prevent
a transmission from one family of twisted pair transmitters from being
inadvertently applied to a twisted pair receiver from an incompatible family.
See the table on page 1-3 and page 1-4 for twisted pair transmitter and
receiver compatibility.
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 from being displayed on specific output devices for
operational security reasons.
