The HDMI Over IP with RS-232 and 2-Way IR Sender Unit from Gefen is a sender (transmitter) which is designed to work with the EXT-HD2IRS-LAN-RX receiver (sold separately). The sender transmits HDMI, RS-232, and IR (bi-directional) over a Gigabit Local Area Network and supports resolutions up to 1080p Full HD and 1920 x 1200 (WUXGA), HDCP, Deep Color, 7.1 channel High Bit Rate digital audio, and lip-sync pass-through. A Cat 5e or higher cable is used for interconnection and may run up to 330' long. To allow the connection of multiple senders and receivers to the same network, unique IP addresses can be automatically or manually configured. Multiple receiver units can simultaneously connect to any sender unit within the network to create a virtual cross-point matrix of just over 65,000 sender and receiver units, depending on the network bandwidth and number of ports on the network switch (sold separately).
IR control can be extended from sender to receiver and from receiver to sender, allowing the control of source units and displays remotely. The IR input ports on sender and receiver units can accommodate both the Gefen powered IR extender EXT-RMT-EXTIRN (sold separately) and electrical IR from automation control devices. RS-232 serial control can also be extended between each sender and receiver pair. The built-in web server interface makes control, set-up, and configuration simple and intuitive. When using multiple senders and receivers as a "virtual matrix," you can connect to any of the senders within the network by accessing the web interface of each receiver unit via a web browser on a mobile device or computer, or by using the Gefen KVM/Video over IP Keyboard Switching Controller software (available for download at Gefen site). This sender and the EXT-HD2IRS-LAN-RX receiver combine to create an HD over IP extender for large scale remote HD content access and digital signage applications.
For one sender to multiple receiver configurations, a Gigabit switch is required. The Gigabit switch must support 8k jumbo frame packets in order for multicast mode to operate; if your LAN is not dedicated to Gefen KVM-LAN products exclusively, then a managed switch is highly recommended. When using HDCP-encrypted content, only HDMI sender and receiver units can accept and display the content.
