Gefen, from Nortek Security & Control (NSC), today announced that it is now shipping its EXT-UHD-LANS-TX, EXT-UHD-LANS-RX, EXT-UHDKA-LANS-TX and EXT-UHDKA-LANS-RX models, all part of the new Gen 2.0 AV Over IP product line. The introduction builds on the Gefen promise to provide systems integrators with scalable, high performance routing and distribution solutions that set new standards for performance and reliability.

“Our new Gen 2.0 AV over IP products address the ever-growing application-specific needs of systems integrators” Gefen Product Manager Jason Fitzgerald said today. “From 4K Ultra HD with HDR support, built-in scalers, and video-wall control, to independent USB, RS-232, audio routing and backward-compatibility with our first generation products, these new solutions offer an expanded array of important new features, performance and functionality. Our mission is to make sure that integrators have the right product for every AV over IP job they deliver and we are tailoring many new product solutions to meet the specific needs of each installation.”

The new EXT-UHDKA-LANS-TX (sender) and EXT-UHDKA-LANS-RX (receiver) solutions enhance AV extension and management for workstation environments where video and USB connectivity is required. In addition to basic KVM functionality, the new KM Emulation feature facilitates real-time simultaneous Keyboard and Mouse control of each source from all connected workstations, eliminating the inherent limitations of earlier systems. “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,” added Fitzgerald.  When used in conjunction with the EXT-CU-LAN Matrix Controller, system configuration is automated and very quick. “Its Mass-Firmware-Update (MFU) feature keeps the entire system up-to-date without the need to access and upgrade each unit separately.”

The Receivers features a built-in scaler to help optimize the image for a variety of displays and different viewing environments. A powerful video wall controller accommodates any screen configuration up to 16×16 and provides flexibility in sizing and manipulating live and signage content in demanding installations. The EXT-UHDKA-LANS-RX’s  integrated USB hub with two USB 2.0 and two USB 1.1 ports accommodates touch panels, keyboard and mouse and a variety of supported devices. This feature, along with analog audio inputs and outputs, make these products perfect for use in collaborative and interactive installations. A built in 2-port Gigabit switch on each Receiver allows the daisy-chaining of additional Receivers or other IP-enabled devices.  In applications, such as digital signage, where content is often replicated on multiple displays throughout the installation, the ability to cascade the Receivers removes the requirement for each cable to be run directly to the main network switch. This extends signal range far beyond the limits of a point-to-point video distribution system.

With support for HDMI and control (RS-232 and IR), the EXT-UHD-LANS-TX (sender) and EXT-UHD-LANS-RX (receiver) are ideal for installations that only require HDMI and control connectivity. In education, hospitality, retail, and signage there will always be a need to manage just video, audio, and control without the USB capability and KVM features offered in the other Gefen 4K UHD AV over IP products.

These new products are capable of 4K 60 Hz 4:2:0 maximum input resolution, and maximum output resolution of 4K 30 Hz 4:4:4. When used with Gefen DVI-to-HDMI cables, they support the use of single-link DVI sources and displays up to 1080p Full HD and 1920×1200 (WUXGA). Each cable run from a Sender to a Receiver or from a Sender or Receiver to the network switch and can be up to 100 meters (330 feet). 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 just over 65,000 Senders and Receivers.
