Video compensation

Adjustable video compensation amplifiers enable the video sharpness to be adjusted using the keyboard. Coarse and fine adjustment control is provided for quick setup. Settings are persistent even when the ADDERLink is powered off which means that setup only needs to be done once. Brightness adjustment is automatic.

Keyboard control

The cable equalisation is controlled in 'configuration mode' using the keyboard attached to the remote (KVM console-end) unit. Configuration mode is accessed using keyboard hotkeys. These hotkeys may also be used to lock the remote unit (if a password has been set). Hotkeys are variable and may be disabled if required. Feedback is provided to the user using the keyboard num, caps and scroll lights.


The remote and local units are fitted with a link/activity indicator that shows the link status and indicate keyboard and mouse data activity.
