About drivers
You don’t need to install any drivers for this KVM switch, as the keyboard and mouse
use generic USB drivers that are already installed on any operating system that
supports USB technology.
Operating the KVM switch
About the LED indicators
There are three LED indicators located on the front of the KVM switch. For more
information about what the LED behavior indicates, see the table below.
LED Behavior Meaning
Computer 1 LED LED is illuminated red Computer is selected
LED is illuminated green Computer is connected
Computer 2 LED LED is illuminated red Computer is selected
LED is illuminated green Computer is connected
Select a port
• To switch between connected computers, press the Select button on the front of
the KVM switch.
The LED of the selected computer illuminates red.
Using hotkey commands
If you’re using a computer that is running a version of Windows® or Linux®, you can use
hotkey commands to operate the KVM switch. All hotkey commands begin by pressing
the Left Ctrl key twice and then pressing one or two additional keys.
The KVM switch emits a high-pitched beep when you enter a correct command and a
low-pitched beep when you enter an incorrect command. Incorrect hotkey commands
aren’t sent to the computer.
To use hotkey commands, the keyboard you’re using needs to be connected to the
Console USB keyboard port.
Note: Hotkey commands aren’t supported in the Mac OS operating system.

Enable or disable hotkey commands
By default, hotkey commands are enabled on the KVM switch.
• To disable hotkey commands, press and hold the Left Shift key and press Num Lock
twice. Release the Left Shift key and then press the Left Ctrl key.
• To enable hotkey commands, press and hold the Left Shift key and press Num Lock
twice. Release the Left Shift key and then press the Left Ctrl key.
Select a computer
To select a computer, press the Left Ctrl key twice and the number of the PC port that
you want to select.
For example, if you wanted to select computer 2, you would press Left Ctrl, Left Ctrl, 2.
Note: Don’t use the numeric keypad on the right side of the keyboard when you
complete the hotkey command above.
Enable or disable Independent Audio Switching
By default, Independent Audio Switching is disabled on the KVM switch, which means
that the audio selection is determined by the computer that you select. For example, if
you select computer 1 and then switch to computer 2, the audio selection changes to
computer 2.
You can enable Independent Audio Switching and make the audio selection
independent from the computer that is currently selected. For example, if you select
computer 1 and then switch to computer 2, the audio selection would remain with
computer 1 until you change it.
• To enable Independent Audio Switching, on the computer with the audio that you
want to listen to, press Left Ctrl, Left Ctrl, F5.
• To disable Independent Audio Switching, press Left Ctrl, Left Ctrl, F5.
The KVM switch beeps once to indicate that Independent Audio Switching is enabled,
and beeps twice to indicate that Independent Audio Switching is disabled.
Alternative hotkey commands
In addition to the Left Ctrl hotkey commands, there are two alternative commands
that you can use to select a computer:
• Press Scroll Lock, Scroll Lock, the number of the PC port that you want to select.
• Press and hold the Left Shift key and press Num Lock twice. Release the Left Shift
key and then press the number of the PC port that you want to select.
Note: Do not use the numeric keypad on the right side of the keyboard when you
complete the hotkey commands listed above.

Troubleshooting
If you experience issues using this KVM switch and you’re using a PC, you may want to
make the following changes to the BIOS settings on your computer:
1. Set HALT ON ERROR to All but keyboard.
2. In PNP AND PCI SETUP, do the following:
• Set PNP OS INSTALLED to YES.
• Set USB IRQ to ENABLED.
I can’t get my wireless mouse and keyboard to work
Some wireless mice and keyboards do work with KVM switches, but in general most
wireless mice and keyboards don’t support KVM switches. If you’re using a wireless
mouse and keyboard in your setup and are experiencing issues with your KVM switch,
try the following:
• Remove the wireless mouse and keyboard transmitter from the Console USB mouse
port and the Console USB keyboard port, and move the transmitter to one of the
USB hub ports on the KVM switch.
Note: Hotkey commands won’t work if the wireless keyboard transmitter is plugged
into one of the USB hub ports.
If you’re still experiencing issues, replace the wireless mouse and keyboard with a
wired mouse and keyboard.
I can’t get my gaming or combination mouse and
keyboard to work
Gaming mice and keyboards and combination mice and keyboards have more buttons
and functionality than 3-button mice and 104-key keyboards. Most KVM switches
don’t support the additional key functions and using them in your setup may impact
the performance of your KVM switch. As such, StarTech.com recommends that you use
a standard 3-button wired mouse and a 104-key wired keyboard in your setup.
My display or video destination uses a dierent type of
video connector than DisplayPort
If the display or video destination in your setup uses a dierent type of video
connector than DisplayPort, you can use a converter to change the output type. For
more information, visit www.StarTech.com to see the dierent types of converters
available.
