Operations
The following paragraphs detail the power-up process and then provide sample
procedures for creating ties, sets of ties, and configurations; changing a
configuration; viewing ties, sets of ties, and configurations; saving a preset;
recalling a preset; viewing and adjusting the audio level; and selecting the front
panel security lockout.
Powering up the switcher
1 . Plug in the switcher. On all switcher models, power is automatically applied
when the power cord is connected to an AC source. When AC power is
applied, the switcher performs a self-test and initialization that sequences the
front panel LEDs on and off from left to right. A successful power up self-test
and initialization leaves the power LED on, the Video and Audio LEDs on,
and all other LEDs off.
The current configuration, all presets, and all input audio levels are saved in
non-volatile memory within 5 seconds of a change or exiting Audio Setup
mode. When power is applied, the most recent configuration is retrieved.
The previous presets remain intact.
Wait at least 5 seconds after changing any configuration, saving a preset, or
exiting Audio Setup mode. Before 5 seconds have elapsed, changes that you
have made may not have been saved.
If an error occurs during the self-test, the switcher locks up and does not
operate. If your switcher locks up on power-up, call the Extron S

Technical Support Hotline.
2 . Plug in all system components and turn on the input devices (such as
computers or HDTV set-top boxes) and the output devices.
3 . Set the input devices to output video using each device’s own operating
instructions.
4 . Create a tie (see below). The selected input image should appear at the
selected output. If no image appears, see Troubleshooting on page 3-26.
Creating a set of ties
You can create a set of ties, changing the current configuration, by using the front
panel buttons. Change the current configuration as follows:
1 . Select to configure video, audio, or both by pressing the I/O button as
necessary.
2 . Select the desired input and output(s) by pressing the input and output
buttons.
3 . Press and release the Enter button.
4 . Repeat steps 1 through 3 to create additional ties until the desired
configuration is complete.
• 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.
• Output LEDs light when an input is selected to indicate current ties.
Press and release the associated output buttons to clear unwanted outputs.
