The Gefen AV over IP Matrix Controller is a powerful and flexible solution for controlling multiple Video over IP (VoIP) extenders within same network. Install this unit on the same local network as the extenders (transmitter and receiver) to easily define and configure both unicast and multicast channel routing selections using the WebGUI. Using customized groups or presets you can define and switch routes allowing for easy control over multiple video zones. The AV over IP Matrix Controller also supports Matrix routing, Independent routing and Video Wall Modes of connected VoIP units. The settings of all connected transmitter / receiver units, including IP address, netmask and extender status are clearly displayed within the WebGUI. Control is available via WebGUI (remote or local), RS-232, Telnet, UDP, IR Remote, and triggers. The WebGUI is accessible via a web browser over a normal network connection or by directly connecting an HDMI display and USB keyboard & mouse to the unit. A standard HDMI/USB Touchscreen display can also be used to interact with the local WebGUI and control to the device. A trigger input interface is also provided to allow the easy addition of a remote device, to be operated from a podium, conference room or classroom.
