The Xcion Digital Extender supports HDMI at 1920x1200 with high quality compressed video over CATx or fiber cable. The standard unit comes with HDMI video input/output, and an HDMI local port on the transmitter unit. USB1.1/USB2.0 is supported up to 12Mbps. The optional USB2.0 device support and switch mode functions are configured on the standard chassis using software keys to activate the selected options. With the USB2.0 device support activated, the unit will support transparent USB2.0 up to 64Mbps. The Switch Mode option enables up to 48 Xcion devices (transmitter and receiver) to be connected to each other using a gigabit network switch, creating a distributed KVM switching system where any user can access any connected host computer resource. Multiple users can also access a single PC/Server using a limited command structure. Management of the Xcion HDMI extender is through an extensive OSD menu structure that is displayed on the connected monitor and operated via keyboard commands. Serial and audio transmission over USB can be supported using external USB adapters.
