Basic Operation
Hotkey Commands
Keyboard hotkey commands allow you to switch the KVM functionality between ports using only the keyboard. You can switch
the KVM, Audio and USB all at the same time, or each one can be switched individually. You can therefore have the KVM focus
on one computer, while the USB Hub ports are being accessed by a second computer, and Audio from a third computer is
playing.
In addition, there are keyboard hotkey commands that can be used to change settings on the KVM switch, such as enabling/
disabling the Alternative Push-Button Commands, initiating Firmware Upgrade Mode, etc.
The following sections describe the hotkey functionality available for the B004-HUA4-K.
Port-Switching Hotkeys
To switch functionality between ports, a keyboard hotkey command is entered that determines what port is accessed and
which functionality is assigned to it. This command starts by pressing [Scroll Lock] [Scroll Lock] or [Ctrl] [Ctrl]. [Scroll Lock]
[Scroll Lock] is used by default. To toggle between these two, see the Alternate Port-Switching Hotkey Command section of
this manual.
The table below contains the Port-Switching Hotkeys used to determine what port is accessed and which functionality is
assigned to it.
Note: The table below uses the [Scroll Lock] [Scroll Lock] preceding sequence. Simply substitute [Ctrl][Ctrl] if you decide to change the
Hotkey Preceding Sequence.
