3. Installation
PC BIOS NOTE:
The following BIOS setup changes are required for PC users and not required for
Mac users.
1. In STANDARD CMOS, set HALT ON ERROR to ALL BUT KEYBOARD.
2. In PNP and PCI SETUP, set PNP OS INSTALLED to YES and set USB IRQ to
ENABLED.
NOTE: The KV9622A or KV9624A is set to switch USB keyboard and mouse
signals from one computer to another. If you plan to share other
peripherals such as a CCD camera, printer, or scanner, you must shut down
the computer’s driver before switching to another computer. Because port
switching is equivalent to unplugging the USB cable from one computer
and plugging it into another computer, some USB drivers check the
attached USB peripherals all the time and are not plug-n-play.
3.1 ServSwitch Placement
The2-or4-PortServSwitchDTSeriesUSB/DVI/AudioKVMSwitchissmall,porta-
ble, and designed to fit on a desktop. Consider the following when deciding

3.2 Hardware Installation
This section provides instructions for the basic hardware setup of a single
ServSwitch.
CAUTION: Before you begin, make sure that power to all the devices that you
will be connecting is turned off.
To prevent damage caused by ground potential differences, make sure
that all devices are properly grounded. If you don’t follow these

Chapter 4: Operation
4. Operation
4.1 Powering Up the System
Once all cables have been connected and all computers have been powered on,
the ServSwitch emulates mouse and keyboard signals on each port, allowing your
computer to boot normally. The ServSwitch is now ready for use.
4.2 Selecting Computers Using Front-Panel Buttons
You can instantly select any computer by pressing the port selector buttons
on the front panel. The corresponding LED will light when the port is selected.
4.3 Selecting Computers Using Hotkey Commands
A hotkey command is a short keyboard sequence used to select a computer,
activate a computer scan, etc. A hotkey sequence starts with two left Ctrl key-
strokes followed by one or two more keystrokes. A built-in buzzer generates a
high-pitched beep for a correct hotkey command. The buzzer sounds one
low-pitched beep to indicate an error (in this case, the bad key sequence will not
be forwarded to the selected computer). Table 4-1 lists hotkey commands and
their functions.
To enable/disable the hotkey commands, press and hold Left-Shift key, then press
Num Lock key twice, then release Shift, and then press Left-Ctrl once.
NOTE: Do not use the keypad to the right of the keyboard.
Table 4-1. Hotkey commands.
Key Sequence Function
Left-Ctrl + Left-Ctrl + 1 Selects the computer connected to Port 1.

USB port selection stops following USB port selection.
Left-Ctrl + Left-Ctrl + U Press this key sequence to select USB for the chosen computer.
NOTE: Link the USB device before switching to the next computer.
4.4 Alternate Hotkey Commands
In addition to the Left-Ctrl + Left-Ctrl hotkeys, there are two other hotkey
sequences programmed into the ServSwitch.
Hotkey sequence #1: Left-Ctrl + Left-Ctrl + _
Hotkey sequence #2: Scroll-Lock + Scroll-Lock + _
Hotkey sequence #3: Left-Shift + Num Lock + Num Lock + _
For keyboards that don’t have or won’t support Scroll Lock, press and HOLD the
Left-Shift key, and then press the Num-Lock key twice. For example, to select a
computer:
Hold Left-Shift + Num-Lock + Num-Lock then release Shift and type 1. This selects
