The Master View Dual-View CS-1744 USB (Universal Serial Bus) KVM Switch brings dual head video functionality to ATEN's USB (Universal Serial Bus) KVM switch technology. Now, four dual head computers can be accessed & controlled from a single console that consists of a USB (Universal Serial Bus) keyboard, USB (Universal Serial Bus) mouse, & two VGA, SVGA, or Multisync monitors. In addition, the CS-1744 incorporates a two port USB (Universal Serial Bus) hub that allows each of the computers to share any USB (Universal Serial Bus) peripherals connected to the hub on a one computer at a time basis. Recognizing the importance of sound, the switches are also audio enabled. A single microphone can provide audio input to each of the computers, & you can listen to the audio output of each computer on a single set of speakers (on a one-at-a-time basis). Please note: networking components such as switches, routers, KVM & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
