An example of creating a set of I/O groups
In the following example one of the four sets of I/O groups are set up. In this
example, input’s 3, 4, and 8, and outputs 2, 3, and 8, are to be assigned to I/O group
#2. All other buttons do not have a group assigned.
N I/O buttons light green when pressed. Do not confuse this with video signal
only inputs or outputs that normally light green. Each input or output within a
group can transmit video only, audio only, or both.
1 . Press Esc to clear all pending changes and reset the LCD (see figure 3-19).
2 . Press and hold down the input and output buttons #1 simultaneously, for
around 3 seconds (see figure 3-19). Those two buttons and the Enter button
will stop flashing. All ungrouped buttons light steady green and the LCD
screen displays the currently grouped input and output buttons, by their
group number.
N In this example input #2 and output #’s 1, 5, and 7, have already been added to
group #1. The remaining ungrouped buttons light green, and the LCD displays
“1” for grouped, and “0” for ungrouped inputs and outputs.
