  • A single computer is shared by two consoles.
  • Serves as the 2nd or the local console in KVM extender applications.
  • Multiple access modes: offer the best control during computer sharing where a user can make control of the system.

The CS261 offers a multi-user/single-task experience that enables two users to share the use of a computer from two consoles (monitor, USB keyboard, USB mouse, speakers and microphone).

The CS261 is ideal for small office environments. All programs, files and resources on the connected computer can be accessed and shared by the two users without the complexity and expense of setting up a network. Users operate the computer on a one by one basis with an optional security feature that can block the video and audio of the console that is not in use.

The CS261 provides a convenient OSD (On Screen Display) that notifies users when the other console is accessing the computer. This allows both users to know at a glance whether or not the PC is available for use.
