Front Panel Operations
Plug in all system components and turn on the input devices
(such as DVD players and DSS receivers) and the output
devices. Set the input devices to output video using each
device’s own operating instructions.
Creating ties
A Tie is an input-to-output connection. An input can be tied to
both outputs. (An output can never be tied to more than one
input.)
Create video and/or audio ties using the front panel buttons as
follows:
1. Press and release the Outputs button to select the desired
output. The LED for the selected output lights.
2. Press and release the Configuration button as necessary
to select either video and audio (audio follow) or video or
audio (audio breakaway).
3. Press and release the button for the desired input. The
LED for the selected input lights.
N
If audio and video are tied from different inputs (audio
breakaway), and if you select video and audio for display,
the Video LED and the LED for the selected video input
light steadily and the Audio LED and the LED for the
selected audio input blink .
A tie can also be created by an RS-232 device (see chapter 4,
"Remote Control").
N
If an output is muted via RS-232, pressing any input
button unmutes the output.
Memory
Audio settings are saved in nonvolatile memory. When the
switcher is powered off, the settings are retained. When
the switcher is powered on again, the switcher recalls the
connections made prior to power down and the saved settings
are active. On initial power on, the switcher defaults to input 1
tied to output 1 and output 2.
