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.  
Features  
Natively supports USB peripherals and DVI video  
Also switches audio for a complete multimedia sharing solution  
Choice of configurable keyboard command sequence or front panel buttons for  
control  
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.

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 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.

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]

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.

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)
