Step 1. Power up your KVM Switch by connecting the external
power adapter to it.
Step 2. Connect the shared USB keyboard, mouse, two
monitors and the speaker system and microphone as
well as other shared USB devices to the KVM switch.
Step 3. Connect each of your computers to the KVM switch
using the DVI-I video cable, USB (Type A-to-Type B)

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

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.

To remove this binding, use the hotkey sequence: ScrLk + ScrLk + X.
3. When the binding of PC & Audio&Micswitching is enabled by the hotkey sequence: ScrLk + ScrLk + Q, any PC and audio&mic switching are bound together.

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 the current control of all hub ports and their connected USB devices.
