Control Buttons
d Control selection buttons — These four buttons give direct 
access to the enter (save), preset, view, and Esc (exit) controls. 
Each button has a separate function. 
NOTES:  •  See Configuring the Rear Panel RS-232/RS-422 Port on page 26 for 
serial port configuration details.
• See Setting the Front Panel Locks (Executive Modes) on page 25 for 
executive modes details.
Enter button — The Enter button flashes green when a change to an input or output 
tie is pending, or red when a preset recall is pending. Pressing the flashing button saves 
the change or recalls the preset, and the Enter button and any lit input and output 
buttons extinguish (see Front Panel Operation on page 16).
Preset button — The Preset button gives access to recall or save up to 32 global presets 
(using I/O buttons 1 through 16), and 10 plane presets (using input buttons 1 through 
10). The button lights red when pressed. Upon recalling or saving the preset, the button 
and all input and output buttons (lit red) are extinguished (see Front Panel Operation 
on page 16 and Saving and Recalling I/O Presets on page 22).
NOTE:  Global presets save and recall the configuration for all planes. Plane presets 
save and recall the configurations for a specific plane without affecting the 
other plane connections.
View (
<
) button — This button, when pressed and released, lights red and allows 
quick viewing of existing input and output ties. When the button is lit, after selecting 
a plane and an associated input, muted outputs flash and untied outputs light the 
appropriate signal color (red, green, or amber). Tied outputs remain unlit.
NOTE:  Use this button to decrease settings for RGB delay, input audio level, and 
output audio volume. This button also mutes and unmutes outputs (see the 
Muting or Unmuting a Video, Audio, or Video and Audio Output on 
page 20).
Esc (
>) button — This button, when pressed, flashes green once and all lit control, 
plane, input, and output buttons are extinguished.

audio volume.
