Introduction
Thank you for purchasing a StarTech.com USB and DVI KVM switch. This product allows
you to switch 2 or 4 computers (depending on the model purchased) including the audio
signal. Designed for today’s cutting edge systems, it features native support for USB
input devices and DVI video. You can save space and improve productivity by sharing
one console among multiple computers without sacrificing the quality of your digital video
signal by using converters and adapters.

Before You Begin
System Requirements
• Console: USB keyboard (1), USB mouse (1), monitor with DVI-I or DVI-D connectors
(1), speakers (optional), microphone (optional)
• Controlled systems: USB support, DVI-I or DVI-D video out, speaker out (optional),
microphone out (optional)
Additional cables required (not included): Each controlled computer will require a
USB Type A to Type B cable (1), DVI-I or DVI-D male-to-male switchbox cable (1),
optional 3.5 mm phono male-to-male sound cable for speakers and microphone (2). See
page 5 for StarTech.com part numbers for all required cables.

Installation
This section details how to connect your computers to the KVM switch. For best results,
ensure that all the computers to be controlled are located as close as possible to the
KVM switch and console peripherals (monitor, keyboard, mouse). This will reduce the
length of cabling required and reduces the chance of interference.
Installing the KVM Switch
1. Place the KVM switch in close proximity to the keyboard, mouse, and monitor you
wish to use as the console controls.
2. Connect the monitor to the DVI port under CONSOLE.
3. Connect a USB keyboard to the Type A connector under CONSOLE, marked with a
keyboard icon.
4. Connect a USB mouse to the Type A connector under CONSOLE, marked with a
mouse icon.
5. Connect speakers to the green 3.5mm phono connector under CONSOLE (optional).
6. Connect a microphone to the pink 3.5mm phono connector under CONSOLE
(optional).
7. Connect up to 2 other USB devices to the ports marked USB HUB (optional).
8. Plug the power adapter into a wall outlet or other suitable power source. Connect the
opposite end to the port marked DC 9V on the KVM switch. (This step is optional,
and is required only if you will be using the KVM switch as a USB hub for other
devices as described in step 7. If you are not connecting devices to the USB HUB
ports, the KVM switch will function as a self-powered device and does not require the
power adapter.)
Connecting Computers to the KVM Switch
This section describes how to connect a computer you wish to control to the KVM switch.
Repeat these steps for each computer you wish to connect.
1. Remove any existing keyboards, mice, monitors, speakers, and microphones from the
computer.
2. Using a DVI-I or DVI-D male-to-male switchbox cable, connect one end to the video
out connector on the computer. (This will be the same connector from which you
disconnected the monitor in step 1, if applicable.) Connect the opposite end to the
DVI connector on the KVM switch that corresponds to the computer number you wish
to use for that system (marked PC 1 ~ PC 2 or PC 1 ~ PC 4 as applicable).

Instruction Manual
3. Using a USB Type A to Type B cable, connect the “A” (flat) end to an available USB
port on the computer. Connect the opposite end to the “B” (D-shaped) USB
connector on the KVM switch that corresponds to the computer number you wish to
use for that system (directly under the monitor connection in step 2). This will provide
both keyboard and mouse access to that system.
4. Optional:You can use 3.5mm male-to-male phono speaker cable to connect the
speaker and/or microphone outputs on the computer to the corresponding connectors
on the KVM switch, located under the monitor connector that corresponds to that
computer on the KVM. Most computers have sound and microphone connectors that
are color-coded to the standard used on the KVM switch: green for speakers, pink for
microphone. See the documentation for the computer for assistance, if needed.
Using the KVM Switch
Green LED (solid) = Active Computer
Green LED (flashing) = No Powered Computer on that Port
Red LED (solid) = Active Control of USB Hub
Button = Switch control to that port
The KVM switch offers two convenient ways to switch console control of the attached
computers. The first is by using the buttons on the front panel to select which computer
is active. The second is using keyboard hotkey combinations, which also allow you to
adjust several configuration options on the KVM. The reference chart on the next page
describes the hotkey commands and their options in detail.
Note: If your computer is configured to use power-saving features (i.e. auto-standby after
inactivity), you may experience intermittent difficulty using the KVM switch. For optimal
performance we recommend configuring your computer’s BIOS setup software to enable
or disable (as applicable) the following options:
• Enable “USB Legacy Support”
• Enable “USB Keyboard and Mouse to bring computer out of standby”
• Disable “Power Saving Mode” for the USB hub
The names and location of these and similar options may vary from computer to
computer. Consult your manufacturer’s documentation for information on accessing and
modifying the BIOS setup if necessary.

Command Name
Hotkey Sequence
Description
Switches access to the computer connected to the
corresponding port number on the KVM.
([x]= a number on the keyboard)
Select active computer
[ScrLk]+[ScrLk]+[x]
Switches which corresponding port number has access to
the to the devices connected to the KVM’s USB hub.
([Fx] = Function key: F1=Port 1, F2=Port 2, etc.)
Select USB hub control
Select Audio/Mic output
[ScrLk]+[ScrLk]+[Fx]
[ScrLk]+[ScrLk]+[Fy]
[ScrLk]+[ScrLk]+[Z]
[ScrLk]+[ScrLk]+[X]
[ScrLk]+[ScrLk]+[Q]
Switches which port’s speaker and microphone output is
active at the console.
([Fy] = Function key: F5=Port 1, F6=Port 2, etc.)
When either the select active computer or select USB hub
control commands are executed, both functions are
switched to the selected port.
Bind computer and USB hub
control (default)
The computer control and USB hub control can be
executed separately; KVM control and USB hub control
control can be assigned to different ports at one time.
Unbind computer and USB
hub control
When either the select active computer or select
audio/mic output control commands are executed, both
functions are switched to the selected port.
Bind computer and Audio/Mic
control (default)
The computer control and USB hub control can be
executed separately; KVM control and Audio/Mic output
control control can be assigned to different ports at one
time.
Unbind computer and
Audio/Mic output control
[ScrLk]+[ScrLk]+[W]
Selects the next (up arrow key) or previous (down arrow
key) numbered port for control.
Select next/previous port
[ScrLk]+[ScrLk]+[arrow]
Select previous port
Beep sound on/off
[ScrLk]+[ScrLk]+[BkSp] Selects the most recent previously active port.
[ScrLk]+[ScrLk]+[B]
Enables/disables audible responses from the KVM.
Change the standard [ScrLk] hotkey to a new value (see
below).
Define new hotkey sequence [ScrLk]+[ScrLk]+[H]+[y]
Automatically switch active ports in sequence every 10
seconds. (Press any key to cancel.)
Autoscan
[ScrLk]+[ScrLk]+[S]
Autoscan with programmable
delay
Autoscan with a delay other than 10 seconds (see below).
Press any key to cancel.
[ScrLk]+[ScrLk]+[S]+[z]
Binding/Unbinding control: By default the switch will automatically switch USB hub and audio control to the KVM
port you select to control (bound). If you choose to “unbind” control, you can assign control of the audio and/or
USB hub to a port other than the active computer using the commands above.
Valid hotkey sequences: If you enter the “Define new hotkey sequence” command ([ScrLk]+[ScrLk]+[H]+[y] the
value of [y] replaces the [ScrLk]+[ScrLk] command with one of the following:
[CapsLk] = [CapsLk]+[CapsLk]
[Esc] = [Esc]+[Esc]
[F12] = [F12]+[F12]
[NumLk] = [NumLk]+[NumLk]
[ScrLk] = [ScrLk]+[ScrLk] (if another key sequence has been enabled)
Programmable Autoscan delay time: [z] can be any one of the following values:
1=10 sec., 2=20 sec. through 9=90 sec., 0=100 sec.
Note: Apple computers will need to be programmed using an IBM-compatible keyboard that has a Scroll Lock key.
