Introduction

The 2/ 4-Port Triple Monitor DVI USB KVM Switch allows 2 or 4 PCs, each with 3 DVI

video outputs, to share monitors, 1 microphone and set of speakers, 1 keyboard and

1 mouse as well as an additional USB 2.0 peripheral such as an external hard drive,

thumb drive, printer, or webcam.

The Triple DVI KVM switch allows you to switch back and forth between multi DVI

PCs at the touch of a button, while maintaining professional-level video quality

on all monitors at resolutions up to 1920x1200. The triple DVI switch also features

an integrated USB hub port that allows USB 2.0 peripherals to be shared between

attached systems - eliminating duplicate peripheral costs, and oering the

convenience of sharing stored data between PCs.

Installation

NOTE: Prior to the installation, please power o all devices that will be connected to

this system.

• Ensure that all devices you will connect are properly grounded.

• Place cables away from uorescent lights, air conditioners, and machines that are

likely to generate electrical noise.

• If you experience any problems using a USB KVM switch, the following BIOS setup

changes may be necessary for PC users and not necessary for Mac users:

• Set ‘HALT ON ERROR’ to ‘ALL BUT KEYBOARD’.

• Under ‘PNP AND PCI SETUP’, set the option ‘PNP OS INSTALLED’ to YES and set

‘USB IRQ’ to ENABLED.

• Dierent systems may use dierent naming, so contact your system manufacturer

for further assistance with these settings.

Hardware Installation

1. Connect up to three monitor(s) into the Console’s DVI connectors; plug a USB

keyboard and a USB mouse into the dedicated USB keyboard and mouse ports on

the KVM switch. If using audio, also connect speakers with 3.5mm mini-jack plugs.

2. Use male-to-male DVI video cable(s) to connect the DVI connector(s) on the

computer’s video card, to the DVI 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.

3. Use a USB type A-B Cable to connect the KVM’s USB port (type B, square connector)

for the PC port used in Step 2, 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).

4. Repeat Steps 2 and 3 for each PC port on the KVM switch, or each computer you

wish to use on the KVM.

5. 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.

6. Connect the external power adapter from a wall outlet to the power connector on

the rear panel of the KVM switch.

7. Power up the rst computer/device and wait for it to fully boot and test keyboard/

mouse functionality.

Instruction Manual

8. Once operation has been successfully conrmed, switch to the next port and power

up that computer/device and conrm.

9. Once completed for all computers/devices connected to the KVM switch, you

should be able to switch between ports freely.

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

Front Panel

Port Selection/Link LED

The LED turns green when the connected computer is powered-on. The

corresponding LED will also illuminate red when that PC port is currently selected.

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 <CTRL> keystrokes

(successively within 0.2 seconds) followed by one or two more keystrokes. A built-in

tone generator creates a high-pitch beep for correct hotkey command; otherwise, one

low-pitch beep is generated for errors and the bad key sequence will not be forwarded

to the selected computer.

NOTE: Press and hold Left <SHIFT> and press <NumLock> twice, then release <SHIFT>

followed by pressing left <CTRL> once, which will enable / disable the hotkey feature.
