Introduction

The LDV-DM712AUSK/LDV-DM714AUSK Dual Monitor DVI KVM

Switch is a 2/4-port TMDS-compliant Dual Monitor DVI KVM Switch

designed for sharing two monitors/Flat Panel Displays –one DVI and one

VGA monitor specifically - between multiple multimedia computers with

Dual Head display [1 x DVI + 1 x VGA]. Its 7.1 channel surround sound

renders a theater digital audio experience that greatly enlivens your DVD

playbacks or gaming sessions. You can sit back and enjoy to the full with

live audio/video output from this KVM switch.

This Dual Monitor DVI USB KVM Switch supports both digital video

(1920 x 1200) and analog video (2048 x 1536) for your maximum

convenience in adapting to your display requirements. It is TMDS-

compliant to support DDC2B emulation and HDCP compliant for digital

contents protection.

This Dual Monitor DVI USB KVM Switch features the latest True

Transparent USB (TTU) Emulation Technology for full compatibility to

all types of keyboards and mice. It also supports All Time Full DDC

Emulation for ultimate video compatibility with all graphic display

scenarios with the latest operating system.

The two USB 2.0 Hub Ports and one USB 2.0 Device Port (topmost

one, marked Device Port)are for sharing high-speed USB 2.0

devices. The USB Device Port and the rest of the two USB Hub

Ports actually belong to two independently operating groups, and

can configure separately for independent/simultaneous switching

with the PC channel. These three USB ports can well offer full

driver support to more advanced USB 2.0 gadgets, since they are

having no emulation and can facilitate a direct signal pass-

through required for these advanced devices. For example, you

can connect a transceiver of your advanced wireless/Bluetooth

keyboard/mouse to either of the three USB 2.0 ports, enabling its

full driver and functional support.

In addition to the keyboard hotkey operation, it provides a full set of

keyboard hotkeys to facilitate your KVM switching operations

such as PC selection and hotkey sequence programming,

autoscanning, autoscan delay time programming, independent/

simultaneous audio&PC switching, etc.

Out-of-the-box Installation

Take the KVM Switch out of the box and begin installation….

Step 1. Power up you KVM Switch by connecting the external power

adapter to it.

Step 2. Connect the shared USB keyboard, mouse, two monitors and

the 7.1 channel speaker system and microphone as well as

other shared USB devices to the KVM switch. If you use an

advanced USB device (such as wireless/Bluetooth mouse, etc)

that needs its own driver for full function, you can connect it to

either the Device port or Hub ports.

Step 3. Connect each of your computers to the KVM switch, using the

DVI-I video cable, VGA cable, USB (Type A-to-Type B) cable

and audio & Mic cables (see the pictures below).

DVI - I VGA Cable USB cable Audio/Mic

Video Cable (HDB15) (TypeA-to-TypeB)

If you need to connect your KVM switch to analog video display card or

analog display monitor, you have to use DVI-HDB adapters for interface

conversions. This KVM Switch supports digital video – 1920 x 1200 / analog

video – 2048 x 1536

Step 4. (Now your KVM Switch should have been powered-up….) Power

up the connected computers one by one. After your computers

are powered up, the keyboard and mouse will be recognized

and now you can begin operating the KVM switch.

And also you should verify the USB device on your Device Port are fully

functioning after installation of its driver on both connected PCs

Easy Operation

There are two methods to control your KVM Switch for PC, USB hub port

as well as audio/mic channel selection: using the front-panel push

buttons and ahotkey sequence.

Front-panel buttons

The front-panel buttons let you have direct control over KVM switch

operation and channel switching. Simply press the PC button for PC port

switching (and if binding is enabled between PC / USB hub port control /

audio & mic switching, they will be jointly selected at the same time). If

you want to enable the binding of PC / Hub port control / Audio&Mic

switching, use the hotkey sequences. See Quick Reference Sheet

Basic configuration (showing only LDV-DM712AUSK)

Keyboard hotkey

A keyboard hotkey sequence consists of at least three specific

keystrokes: See Quick Reference Sheet

Hotkey sequence = [ScrLk]* + [ScrLk] * + Command key(s)

* User-definable = SCROLL LOCK,CAPS,ESC,F12 or NUM LOCK

Hotkey preceding sequence configuration: For users who want to use a

preceding sequence other than two consecutive Scroll Locks, there is also one

convenient way to configure it. (1)Hit ScrollLock + ScrollLock + H, then two beeps

will signal readiness for new preceding sequence selection [or Press and hold

down the last front-panel button (Button 2) until you hear two beeps, then release

the button.] (2) Select and press the key you would like to use as your preceding

sequence (SCROLL LOCK,CAPS,ESC,F12 or NUM LOCK keys are available

for selection) and you’ll hear a beep for selection confirmation. Now you can use

the new preceding sequence to execute your hotkey commands.

Each keystroke within a hotkey sequence should be pressed within 2

seconds. Otherwise, the hotkey sequence will not be validated.

For detailed Hotkey sequences and their corresponding functional commands,

please refer to the Quick reference sheet.

LED Information: Green LED indicates PC port status: solid green – active port; flashing green – PC not connected; Red LED indicates hub port control status: solid red – that PC has the control of all hub ports.

Important Note: The USB hub control status LED (red) indicates not the connected status of each USB device, but indicates which PC port has the control of all hub ports and their connected devices. For example, when USB LED 1 is lit, it means PC port 1 has
