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 LEDs, output LEDs, or control LEDs that may be lit.
2. Select to congure video, audio, or both by pressing the Video button and Audio
button.
3. Select the desired input and outputs by pressing the input and output buttons.
To indicate potential ties, output LEDs blink when an output is selected but not tied to
the input.
To indicate current ties, output LEDs light steadily when an input is tied to the output.
To clear unwanted outputs, press and release the output buttons associated with the lit
LEDs. To indicate potential unties, output LEDs blink 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 additional ties until the desired configuration is
complete.
NOTES:• Video ties cannot be made between the computer video group and the
low resolution video group.
• Audio ties can only be made to the computer video and audio subgroup
(outputs 1 through 6).
• Video and audio ties between the low resolution video input subgroup
and the low resolution video output subgroup are made with the audio
automatically redirected. In such an operation, the switcher automatically
ties the audio to an output in the computer video and audio outputs
subgroup (outputs 1 through 6) as follows.
If the video is tied to output: The audio is tied to output:
7 1
8 2
9 3
10 4
11 5
12 6
• If video is selected for conguration (the Video LED is lit) and you press
the input button for an input in one group and then try to select an
output in the other group, the associated output button cannot be
selected. The associated input LED remains lit.
• Only one video input and one audio input can be tied to an output.
• If a tie is made in which 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 LED for that input lights.
• When the Video and Audio LEDs are lit, if an input with an audio tie but
no video tie is selected, the LED for the input lights and the output LED
and I/O Audio LEDs blink.
• As each input and output is selected, the associated output LED blinks
to indicate a tentative tie. LEDs for outputs that were already tied to the
input light steadily. Outputs that are already tied can be left on, along
with new blinking selections, or toggled off by pressing the associated
output button.
