Seamless switching with Adder Free-Flow technology

Free-Flow allows users to automatically switch between target computers simply by moving the mouse pointer from screen to screen. Unlike software-only variants, no software or networking is required on your mission critical computers for Free-Flow to work.

Improved desk ergonomics

With only one keyboard and mouse required to operate four computer systems, the desk space can be made more ergonomically effective and reduces the time taken for operators to multiplex to different systems.

Multi-Monitor Free-Flow

The system is able to support four monitors per computer. To enable Free-Flow on multi-monitor computers, a driver must be installed on the target computer. This feature is currently available for Windows computers only.

External control options

The unit can be controlled and switched via hotkeys, mouse clicks, Ethernet, RS232 or remote 3 button mouse. With the open API, the unit can be easily set up and integrated into 3rd party systems.

Instant switching with True USB Emulation

Adder’s True USB Emulation technology overcomes limitations of other KVM switches by emulating the true character of the connected devices to all the computers simultaneously. This means that you can use the extra function keys, wheels, buttons and controls, without sacrificing switching times.

Independent simultaneous device selection

Switching options enable you to use the keyboard and mouse on one computer whilst your USB peripherals and speakers are independently connected to different computers. You can of course still switch all the connected devices to any one of the connected computers.

Screen illumination module

The CCS-XB illumination module is an optional accessory which connects to the CCS-PRO4. It gives users the option to have a LED indicator positioned on each screen to identify which screen is currently controlling. The color and intensity can be controlled for each screen. A maximum of ten LED indicators can be supported.

Redundant power

For mission critical applications, dual power inlets are now available.
