Creating a configuration
The current configuration can be changed using the front panel buttons. Change
the current configuration as follows:
1 . Press the Esc button to clear any input button indicators, output button
indicators, or control button indicators that may be lit.
2 . Select video, audio, or both for configuration by pressing the Video button
and/or Audio button.
3 . Select the desired input and output(s) by pressing the input and output
buttons.

Input buttons and output buttons light or blink amber to indicate video
and audio ties, green to indicate video only ties, and red to indicate audio
only ties.

To indicate potential ties , output buttons blink the appropriate color
when an input is selected.

To indicate current ties , output buttons light steadily the appropriate
color when an input is selected.

To clear unwanted outputs, press and release the associated lit output
buttons. To indicate potential unties , output buttons blink the
appropriate color when an output is deselected but not untied from the
input.
4 . Press and release the Enter button to accept the tie or to break an existing tie.
5 . Repeat steps 1 through 4 to create or clear additional ties until the desired
configuration is complete.
N
• Only one video input and one audio input can be tied to an output.
• If a tie is made between an input and an output, and the selected output was
previously tied to another input, the older tie is broken in favor of the newer
tie.
• If an input with no tie is selected, only the selected input’s button lights.
• When the Video button and the Audio button are lit, if an input with an
audio tie but no video tie is selected, the input’s button and the output’s
button light the appropriate color (amber, green, or red).
• As each input and output is selected, the associated output button blinks the
appropriate color to indicate a tentative tie. Buttons for output(s) that were
already tied to the input light the appropriate color steadily. Outputs that are
already tied can be left on, along with new blinking selections, or toggled off
by pressing the associated output button.
• Extron recommends against tying a local (VGA) input to a local (VGA)
output; the image displayed from such a tie may be overpeaked.
• If you press the input button for an I/O grouped input and then try to select
an output in a different group, you cannot select the associated output
button. The associated input button remains lit.
