Easy Operation

There are two methods to control your dual monitor KVM Switch: using the front-panel push buttons and keyboard hotkey sequence.

Front-Panel Push Buttons

The front-panel push buttons let you have direct control over KVM Switch operation and channel switching. Simply press the PC

selection button for PC port switching, if binding is enabled the console USB hub ports and audio&mic ports, they will be jointly selected

at the same time. If you want to enable the binding feature use the hotkey sequence.

See Quick Reference Sheet

Keyboard Hotkeys

A keyboard hotkey sequence consists of at least three specific keystrokes:

See Quick Reference Sheet

Hotkey Sequence = [ScrLk]

+ [ScrLk]

+ [Command key]

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

Hotkey preceding sequence configuration:

For users who want to use a hotkey preceding sequence other than the default two consecutive Scroll Lock, there is a convenient way to

configure it.

(1) Hit ScrollLock + ScrollLock + H, then two beeps sound will signal readiness for new hotkey preceding sequence selection or press

and hold down the last front-panel push button (Button 2/4) until you hear two beeps, then release the push button.

(2) Select and press the specific key that you would like to use as your hotkey preceding sequence (SCROLL LOCK, CAPS LOCK, ESC,

F12 or NUM LOCK keys are available for selection) then you’ll hear a beep sound for selection confirmation. Now you can use the

new hotkey preceding sequence to execute your hotkey command.

Each keystroke within a hotkey sequence should be pressed within two seconds. Otherwise, the hotkey sequence will not be validated.

For more details about keyboard hotkey sequence and their corresponding functional commands, please refer to the Quick Reference Sheet.

Notes:

1. The USB keyboard hotkeys allows you a faster and broader control for your KVM switching operation in addition to the front-panel buttons. If you have configured a hotkey preceding sequence other than two consecutive scroll locks, you should change your hotkey sequence accordingly.

(For preceding sequence key configuration, please refer to Quick Installation Guide)

2. When the binding of PC & USB hub port control switching is enabled by the hotkey sequence: ScrLk + ScrLk + Z, any PC and hub port control switching is bound together. To remove this binding, use the hotkey sequence: ScrLk + ScrLk + X.

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

LED Information: Green LED indicates PC port connection status between the KVM Switch and computer: solid green – established; flashing green – not connected; Red LED indicates KVM Switch USB hub port control status: solid red – PC has the control of all USB hub ports; off – PC has no control.

Important Note: The red LED, USB hub port control status, indicates which PC has the full control of all USB hub ports and their connected devices on the KVM Switch.

For example, when red LED 1 is lit, it means PC port 1 has the current full control of all USB hub ports and their connected USB devices on the KVM Switch.
