Gefen Ext-Uhd-Lans-Tx 4K Ultra Hd Hdmi Over Ip Sender Package



Extend and Distribute 4K HDMI w/ HDR, RS-232, IR, and audio over a LAN

Gefen’s AV over IP solutions continue their tradition of providing high performance, scalable, expandable, and secure AV routing and distribution over a standard Gigabit Local Area Network. The Gen 2.0 KVM products offer enhanced performance, features, and functionality such as 4K Ultra HD with HDR support, built-in scalers, video-wall control, independent RS-232, IR, and audio routing**, and backward-compatibility with our first generation products.

The EXT-UHD-LANS-TX & RX feature maximum input resolution of 4K 60 Hz 4:2:0, and maximum output resolution of 4K 30 Hz 4:4:4. HDCP 2.2 and 1.4 are also supported. 7.1 channels of HBR (High Bit Rate) lossless and LPCM digital audio can pass through the system as well.

Video, RS-232 2-way IR, and audio can be routed independently** between any Sender and Receiver unit, allowing end-users to control any of the sources and the displays within their network. With this greatly expanded array of new cutting-edge features and performance, the new Gefen AV over IP products fully address the ever-growing needs of systems integrators.

The Receiver features a built-in scaler to help optimize the image for a variety of displays and different viewing environments. It also includes a powerful video wall controller that accommodates any screen configuration up to 16×16 and provides great flexibility in sizing and manipulating live and signage content in demanding installations. Digital and analog audio break-out de-embeds audio from the video and sends it to a separate audio system, enhancing the impact of presentations.

Power-over-Ethernet allows the Sender and Receiver units to be powered through a standard PoE-enabled IP network switch, without the need for external power supplies. When used in conjunction with the EXT-CU-LAN Matrix Controller, system configuration is automated and quick. Its MFU (Mass-Firmware-Update) feature keeps the entire system up-to-date without the need to access and upgrade each unit separately. Enhanced network security by separating the control and AV networks is also made possible with the EXT-CU-LAN. Other control options include front panel buttons, web server interface, Telnet, UDP, and the Gefen Keyboard Switching Controller software (available for download at Gefen’s Enhanced API provides added functionality and facilitates use with third party controllers. The Gefen Gen 2.0 AV over IP products have been specifically designed for use with the Gefen Syner-G™ software, available for download at The Gefen Syner-G™ Discovery and Show-Me features greatly simplify initial IP configuration. 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). A built-in 2-port Gigabit switch on the Receiver allows daisy-chaining of additional Receivers or other IP-enabled devices. In applications such as digital signage, where there is a need to replicate content on multiple displays, the ability to cascade Receivers removes the requirement for each cable to be run directly to the main network switch, thereby extending the range of these units far beyond the limits of a point-to-point video distribution system. The Sender and Receiver can be used as extenders in a one-to-one system, or as nodes in a virtual matrix environment where any source can be routed to any or all displays, supporting up to 39,900 Senders and a combination of over 65,000 units. Applications include high performance AV and signage systems in sports bars, clubs, restaurants, board and huddle rooms, command and control centers, museums, airports, classrooms, auditoriums, hotels, and retail establishments. The low-profile Sender and Receiver units feature a half-rack-width enclosure, perfect for rack-mounting using the Gefen EXT-RACK-1U-GRY rack tray (available separately). They can also be surface-mounted, placed on a shelf, or tucked away in the equipment closet or behind a display.
