DVI – I USB cable Audio&Mic

Video Cable (Type A-to-Type B)

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 USB Hub Ports

are fully functioning after installation of its driver on both connected PCs.

If you need to connect to the analog video source (HDB15), you

might need to use a HDB-DVI adapter to facilitate connection with the

KVM switch.

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 or a hotkey 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

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.
