Gefen EXT-UHDV-KA-LANS-RX 4K Ultra HD HDMI and VGA KVM over IP Receiver

Brand: Gefen


Gefen’s Video over IP solutions continue our tradition of providing high performance, scalable, expandable, and secure AV routing and distribution over a standard Gigabit Local Area Network. The Gefen 4K Ultra HD and VGA KVM over IP extends HDMI, VGA, USB, 2-way audio, RS-232, and IR. The Sender features a 1U tall and half-rack-width enclosure, perfect for rack mounting using the Gefen EXT-RACK-1U-GRY rack tray (available separately). It can also be surface mounted or be placed on a shelf. The Receiver is also rack mountable using the rack tray, can be surface-mounted, or can be placed on a shelf.?? When used with the included IR Extender module, this low-profile unit can be hidden away behind a display or in the equipment closet. The Sender and Receiver can be used as KVM extenders in a one-to-one system by connecting them directly with an Ethernet cable. Each cable run from a Sender to a Receiver or from a Sender or Receiver to the network switch can be up to 100 meters (330 feet).
