ower
adapter to it.
( 2 ) T hen connect the shared keyboard mouse monitors al
so
speaker s a nd microphone to the KVM switch then

before
making connections to t he VM switch.

Notes:
1. The keyboard hotkeys, console keyboard only, allows you a faster and broader control for your KVM switching operation in addition to the front-panel push button. If you have configured a keyboard hotkey preceding
sequence other than two consecutive scroll lock keys, you should change your keyboard hotkey sequence accordingly. (For preceding sequence key configuration, please refer to Quick Installation Guide)
2. When the binding of PC and USB Hub ports switching is enabled by the keyboard hotkey sequence: ScrLk + ScrLk + Z, PC port and USB Hub ports control switching are bound together.
To disable this binding feature, use the keyboard hotkey sequence: ScrLk + ScrLk + X.
3. When the binding of PC and Audio/Mic switching is enabled by the keyboard hotkey sequence: ScrLk + ScrLk + Q, PC port and audio/mic switching are bound together.
To disable this binding feature, use the keyboard hotkey sequence: ScrLk + ScrLk + W.
LED Information: Green LED indicates between PC channel and KVM Switch USB ports (keyboard, mouse and USB Hub ports) connection status: Solid green – Link established; Flashing green – Link not established.
Red LED indicates between PC channel and KVM Switch USB Hub ports access control status: Solid red – Grant full access control of all USB Hub ports; Off – Access not granted.
Important Note: The USB Hub ports access control status LED (red) indicates not the connection status of each USB device, but indicates which PC channel has the full access control of all USB Hub ports and connected devices.
For example, when HUB 1 LED (red) is lit, it means PC 1 channel has the current full access control of all USB Hub ports and connected USB devices.
