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.
