Introduction

Thank you for purchasing a StarTech.com USB desktop KVM switch with audio

switching. 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 VGA video. You can save

space and improve productivity by sharing one console among multiple computers

without sacricing the quality of your video signal by using converters and adapters.

Features

• Natively supports USB peripherals and VGA video

• Also switches audio for a complete multimedia sharing solution

• Choice of congurable hotkey command sequence or front panel buttons for

control

Package Contents

• 1 x USB Desktop KVM Switch

• 1 x Power Adapter

• 1 x Instruction Manual

System Requirements

• Console: USB keyboard (1), USB mouse (1), VGA monitor(1), speakers (optional),

microphone (optional)

• Controlled systems: USB support, VGA 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) and VGA switchbox cable (1) or StarTech.com 2-in-1

USB VM 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

Place the KVM switch in close proximity to the keyboard, mouse, and monitor you wish

to use as the console controls.

1. Connect the monitor to the VGA port under CONSOLE.

2. Connect a USB keyboard to the Type A connector under CONSOLE, marked with a

keyboard icon.

3. Connect a USB mouse to the Type A connector under CONSOLE, marked with a

mouse icon.

4. Connect speakers to the green 3.5mm phono connector under CONSOLE (optional).

5. Connect a microphone to the pink 3.5mm phono connector under CONSOLE (optional).

6. Connect up to 2 other USB devices to the ports marked USB HUB (optional).

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.

7. Remove any existing keyboards, mice, monitors, speakers, and microphones from

the computer.

8. Using a KVM 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 video 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

9. 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 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.

10.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 oers 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 conguration 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 congured to use power-saving features (i.e. auto-standby

after inactivity), you may experience intermittent diculty using the KVM switch.

For optimal performance we recommend conguring 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.
