Gefen GF-HDK18G-VIP-TX is a high-performance 4K HDMI and USB-C KVM over IP Sender unit that - along with Receiver unit(s) - extends and distributes Ultra-HD video sources, audio, and control signals over a standard Gigabit local area network (LAN).
This powerful Sender unit allows you to extend 4K 60Hz 4:4:4 video with HDR, along with audio, USB, RS-232, and bi-directional IR, up to 330 feet (100 m) from any Receiver unit on the network.
Part of a flexible and scalable AV over IP system, this Sender, when used with a Receiver, can be used in a simple extender configuration or expanded to a sophisticated virtual matrix KVM switch system.
By pairing this Sender with one or more Receivers, you can control any source from any display on the network, making it an ideal AV over IP solution for professional AV, digital signage, and high-performance KVM applications.
Ideal for large-scale remote workstation access, digital signage, and high-performance AV applications, this HDMI extender solution offers a versatile and massively scalable system for your professional AV and IT needs.
Power-over-Ethernet allows Sender and Receiver units to be powered through a standard PoE-enabled IP network switch, without the need for external power supplies.
Each cable run from a Sender to a Receiver or from a Sender or Receiver to the network switch can be up to 330 feet (100 m). A built-in 2-port Gigabit switch on the Sender allows daisy-chaining of additional Senders 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 Senders 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.

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 - see listing below). They can also be surface-mounted, placed on a shelf, or tucked away in the equipment closet or behind a display.
When used in conjunction with GF-AVIP-MC AVoIP Matrix Controller (purchased separately - see listing below), 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 GF-AVIP-MC. Other control options include front panel buttons, Web server interface, Telnet, UDP, and the Gefen Keyboard Switching Controller software (available for download at www.gefen.com).

How It Works
Gefen HDK18G-VIP system operates with two main components: a Sender unit and one or more Receiver units (sold separately) connected over a standard Gigabit LAN (local area network).
The Sender unit connects to your HDMI or USB-C source device, and the Receiver unit connects to your display.
Using an Ethernet switch, the system extends signals up to 330 feet (100 m).
First, connect your 4K Ultra-HD source, such as a computer or media player, to the HDMI or USB-C input on the Sender unit.
The Sender unit is then connected via a CATx cable to a managed Gigabit IP Ethernet switch on LAN.
A Receiver unit is connected to each display and also to the same network switch. This setup allows signals to be transmitted up to 330 feet (100 m) between any Sender and Receiver.
By setting the channel ID on the Sender and Receiver units to match, you can route the source signal to the desired display.
By adding multiple Senders and Receivers to the network, you can create a flexible and massively scalable virtual matrix, allowing any connected console to control any source on the network.
