Introduction

The SV231DDVDUA 2-port or SV431DDVDUA 4-port Dual Monitor KVM Switch

(DVI+VGA) oers a complete multimedia switching solution, letting users control two

Dual Display computers using a single USB mouse and keyboard peripheral set.

With support for high-resolution video interfaces, this dual view KVM switch provides

one VGA (analog) and one DVI-I port per computer connection, as well as audio

switching capability between connected computers.

Delivering versatility for virtually any application, the DVI/VGA 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 oers a compact desktop KVM

design and features a rugged metal chassis that helps ensure durable performance.

Please 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.

Backed by a StarTech.com 3-year warranty and free lifetime technical support.

Instruction Manual

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.

In PNP AND PCI SETUP, set 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. Plug 1 or 2 monitor(s) into the Console side DVI and/or VGA connectors; plug a USB

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

the KVM switch.

2. Use a male-to-male DVI and/or VGA video cable to connect the DVI/VGA

connector(s) on the computer’s video card, to one of the KVM’s PC ports (ie. PC1). A

dedicated video, USB and audio 4-in-1 KVM cable can be used (ie. StarTech.com ID:

USBDVI4N1A6 (DVI) or USBVGA4N1A6 (VGA)).

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).

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

wish to use on the KVM.

Instruction Manual

OPTIONAL: Connect any other USB peripherals you wish to share between the

connected computers/devices to the extra USB Hub ports on the Console side.

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

the rear panel of the KVM switch. The Power LED should light up solid and/or the

LED for the selected PC port.

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

mouse functionality.

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

up that computer/device and conrm.

Driver Installation

No driver installation is required for the KVM switch, as the keyboard and mouse uses

native USB keyboard/mouse drivers that are already installed on all operating systems

that fully support USB.

Instruction Manual

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.

Port Selection Button

2 Port: Pressing the front panel “Select” button toggles between the PC ports on the

KVM switch.

4 Port: Each push button on the front panel corresponds with a PC port. Pressing the

button will immediately select that port.

Auto Scan

The KVM automatically scans through the powered-on computers in sequence on a

xed time interval (see Scan Time below).

To activate Auto Scan, press down front panel push buttons “3” and “4” simultaneously.

The port LED ashes during Auto Scan. Auto Scan is eective for powered-on

computers only. To exit the Auto Scan mode, just tap any one of the push buttons.

(SV431DDVDUA only)

NOTE: When Auto Scan detects any keyboard activity, it suspends the scanning until

the activity stops; it then resumes with the next computer in sequence. The length of

the Auto Scan interval (Scan Rate) is adjustable, see below.

Scan Time

Four options are available for users to set the Scan Time duration, which includes 3, 8,

15 and 30 seconds.

To change the Scan Time interval, press both front panel buttons “1” and “2”

simultaneously. The unit beeps 1, 2, 3 or 4 times for Scan Time of 3, 8, 15 or 30 seconds

respectively. (SV431DDVDUA only)

NOTE: Scan Time is automatically set to the default of 3 seconds when the units loses power.

Instruction Manual

Rear Panel (SV431DDVDUA only)

To adjust the video signal strength/equalization settings for the length or quality of

DVI cable being used, the “FUNC” button combined with the front panel push buttons

can be used.

1. Press “FUNC” button three times, and the LED for “POWER” will start to ash once

per second.

2. Press front panel push button“1” one or two times to adjust the signal equalization

with one beep (normal) or two beeps (enhance) respectively.

Press front panel push button“3” one or two times to adjust the video signal output

current with one beep (normal) or two beeps (enhance) respectively.

Press front panel push button“4” one, two, three, or four times to adjust the output

emphasis with one beep (no pre-emphasis), two beeps (low pre-emphasis), three

beeps (medium pre-emphasis), or four beeps (high pre-emphasis).

3. Once the settings have been adjusted, press the “FUNC” button one time to exit

this mode.

Instruction Manual

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 high-

pitch beep will be generated for each 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.

To select a computer:

Left <CTRL> + Left <CTRL> + <1>

(Example: Selects the computer at port 1.)

Left <CTRL> + Left <CTRL> + <2>

(Example: Selects the computer at port 2.)

NOTE: Do not use the keypad on the right-side of the keyboard.

Auto Scan

The KVM automatically scans through the powered-on computers in sequence on a

xed time interval (see Scan Time below).

To start Auto Scan:

Left <CTRL> + Left <CTRL> + <F1>

To abort the Auto Scan mode, press the left <CTRL> key twice.

NOTE: When Auto Scan detects any keyboard activity, it suspends the scanning until

the activity stops; it then resumes with the next computer in sequence. The length of

the Auto Scan interval (Scan Rate) is adjustable, see below.

Manual Scan allows users to manually switch back and forth between

powered-on computers.

Left <CTRL> + Left <CTRL> + <F2>

To select the previous or the next computer, press <UP> or <DOWN> arrow keys. To

abort the Manual Scan, press any other key.
