Operation
Port Selection Buttons
The Front Panel buttons allow direct control over KVM switch operation and channel
switching. Simply press the PC button for PC port switching. If binding is enabled
between PC / USB hub port control / Audio and Mic switching, they will be jointly
selected at the same time). If you wish to enable the binding of PC / Hub Port control /
Audio and Mic switching, see “Hotkeys” section.
Port Selection LEDs
The green ‘PC’ LED indicates the currently selected computer that has keyboard and
mouse, audio and video access. The red ‘HUB’ LED indicates the currently selected
computer that has access to the USB hub ports.
Hotkey Control
A Hotkey command is a short keyboard sequence for selecting a computer, activating
computer scan, etc. A hotkey sequence starts with two left <ScrLk> (Scroll Lock)
keystrokes (successively within 2 seconds) followed by one or two more keystrokes.
A built-in tone generator creates a high-pitch beep for correct hotkey command;
otherwise, errors and bad key sequences will not be forwarded to the currently
selected computer.
The two proceeding keystrokes can be changed if desired. Press <ScrLk> + <ScrLk> +
<H>, which will be followed by two beeps indicating readiness for selection of a new
preceding sequence, or press and hold down the last front-panel button (Button 2 on
SV231DDUSB, Button 4 on SV431DDUSB) until you hear two beeps, then release the
button.
Select and press the key you would like to use as your preceding sequence (Scroll Lock,
Caps Lock, ESC, F12 or Num Lock) and you’ll hear a beep for confirmation. The new
preceding sequence can now be used to execute hotkey commands.
