Introduction
Thank you for purchasing a StarTech.com USB and DVI KVM switch. This product allows
you to switch between 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 sacricing the
quality of your digital video signal by using converters and adapters.
Packaging Contents
• USB + DVI KVM Switch (1)
• Power Adapter (1)
• Instruction Manual (1)
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.
Instruction Manual

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
otherdevices 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).
3. Using a USB Type A to Type B cable, connect the “A” (at) 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 wishto
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 (ashing) = No Powered Computer on that Port
Red LED (solid) = Active Control of USB Hub
Button = Switch control to that port
The KVM switch oers two convenient ways to switch console control of the attached
computers. The rst 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 conguration 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 congured to use power-saving features (i.e. auto-standby
after inactivity), you may experience intermittent diculty using the KVM switch.
For optimal performance we recommend conguring 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.

Binding/Unbinding control: By default the switch will automatically switch audio
control to the KVM port you select to control (bound). If you choose to “unbind”
control, you can assign control of the audio to a port other than the active computer
using the commands above.
Valid hotkey sequences: If you enter the “Dene 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.
