Introduction
The StarTech.com SV231DDUSB 2-port Dual Monitor KVM Switch (DVI+VGA) oers
a complete dual display multimedia switching solution, allowing users to control 2
computers using a single USB mouse and keyboard peripheral set.
With support for high-resolution video interfaces, the versatile dual monitor KVM
switch provides 1 VGA (analog) and 1 DVI-I port per computer connection, as well as
audio switching capability between connected computers.
Delivering the capability you need for virtually any application, the dual monitor
KVM switch features an integrated 2-port USB hub that allows connected USB 2.0
peripherals to be shared between connected computers, eliminating the need to
purchase duplicate peripherals.
Suitable for any workspace, the dual monitor KVM switch features a compact, desktop
KVM design and features a rugged metal chassis that helps ensure durability.
NOTE: While both DVI-I (analog mode) and DVI-D (digital only) are supported by the
KVM, both source PCs must output the same signal type for proper switching. It is
recommended wherever possible to use DVI-D cables across all PC to KVM and KVM
to Console connections. If necessary, please contact our technical support team for
assistance identifying your source.
The 2-port DVI+VGA dual monitor KVM switch is backed by a StarTech.com 2-year
warranty and free lifetime technical support.

Installation
Hardware Installation
NOTE: Prior to the installation, please power o all devices that will be connected to
this system.
1. Place the KVM switch in close proximity to the keyboard, mouse, and monitor(s) you
wish to use as the console controls.
2. Connect the USB keyboard, mouse, speakers and microphone (if applicable) to the
KVM switch.
3. Connect the DVI monitor into the Console’s DVI connector.
4. Connect the VGA monitor into the Console’s VGA connector.
OPTIONAL: Connect any other USB peripheral you wish to share between the
connected computers/devices to the extra USB Hub port on the Console side.
5. Use male-to-male video cables to connect the DVI and VGA connectors on the
computer’s video card, to the DVI and VGA ports for one of the KVM’s PC ports (i.e. PC1).
NOTE: Do not mix dierent types of DVI cables (DVI-I, DVI-D) on the same KVM switch.
6. Use a USB type A-B Cable to connect the KVM’s USB port (type B, square connector)
for the PC port used in the previous step, and the USB port on the computer (type A,
at connector). If using audio, connect 3.5mm mini-jack cables from the PC port to
the sound card.
NOTE: DVI + USB + Audio KVM combo cables are also available which can be used
in place of separate individual cables (e.g. StarTech.com ID: DVI4N1USB6).
7. Repeat the previous two steps for each PC port on the KVM switch, or each
computer you wish to use on the KVM switch.
8. Connect the external power adapter from a wall outlet to the power connector on
the rear panel of the KVM switch.
9. Power up the rst computer/device and wait for it to fully boot and test keyboard/
mouse functionality.
Driver Installation
No driver installation is required for the KVM switch, as the keyboard/mouse use USB
drivers that are already installed on any operating system that fully supports USB.

Operation
Port Selection Buttons
The Front Panel buttons allow direct control over KVM switch operation and channel
switching. Simply press the PC button for PC port switching. If binding is enabled
between PC / USB hub port control / Audio and Mic switching, they will be jointly
selected at the same time). If you wish to enable the binding of PC / Hub Port control /
Audio and Mic switching, see “Hotkeys” section.
Port Selection LEDs
The green ‘PC’ LED indicates the currently selected computer that has keyboard and
mouse, audio and video access. The red‘HUB’ LED indicates the currently selected
computer that has access to the USB hub ports.
Hotkey Control
A Hotkey command is a short keyboard sequence for selecting a computer, activating
computer scan, etc. A hotkey sequence starts with two left <ScrLk> (Scroll Lock)
keystrokes (successively within 2 seconds) followed by one or two more keystrokes.
A built-in tone generator creates a high-pitch beep for correct hotkey command;
otherwise, errors and bad key sequences will not be forwarded to the currently
selected computer.
The two proceeding keystrokes can be changed if desired. Press <ScrLk> + <ScrLk> +
<H>, which will be followed by two beeps indicating readiness for selection of a new
preceding sequence, or press and hold down the last front-panel button (Button 2 on
SV231DDUSB, Button 4 on SV431DDUSB) until you hear two beeps, then release the
button.
Select and press the key you would like to use as your preceding sequence (Scroll Lock,
Caps Lock, ESC, F12 or Num Lock) and you’ll hear a beep for conrmation. The new
preceding sequence can now be used to execute hotkey commands.
