Emerald® 4K KVM-over-IP Extender Transmitter - DisplayPort, Single-Head, V-USB 2.0, Audio - 1 Computer(s) - 32808.40 ft Range - 4K - 4096 x 2160 Maximum Video Resolution - 1 x Network (RJ-45) - 1 x USB - DisplayPort - 120 V AC, 230 V AC Input Voltage
Emerald 4K transmitters and receivers deliver pixel-perfect video with HD or 4K/60 resolutions over an IP network.
Users working on the system experience fast and easy-to-use access to their target servers with premium video quality and a rich peripheral set supporting stereo audio and up to any four true emulated USB 2.0 devices including Wacom® tablets. Administrators require comprehensive management with convenient configuration options in line with high-level security and reliable operation.
Emerald 4K Transmitters are infinitely scalable, starting as simple extenders, or part of a smaller switchable matrix over a network, or by adding a Boxilla on the network you can have a KVM over IP switchable system or hundreds or even thousands of devices providing access across locations.
System Design
Emerald comprises of a choice of transmitters connecting computers or virtual machines to the system and receivers adding the user consoles. Uniquely Emerald offers a range the EMS range of Emerald network switches this allows management of the entire KVM network and monitoring of the system down to port level, A range of SFP/SFP+ transceivers prove best performing video quality and KVM extensions over the required distances.
Use the Emerald units featured on this page to connect DisplayPort and consoles with resolutions up to 4K/60, transparent USB 2.0, and bi-directional analog audio to your Emerald system.
Instant access across the whole Enterprise
Emerald makes access simple, enabling you to scale access infinitely and gradually across buildings, campuses, and the wide-area network, using your existing network infrastructure - with switching between sources at speeds of less than half a second.
Digital video at its best
Emerald is the first KVM platform that supports pixel-perfect 4K DisplayPort video at 60 Hz over standard IP network switches using copper or fiber cable. Image transmission with mathematical lossless compression visualizes every single pixel at 60 fps with 8-bit color depth. If you are not ready for 4K yet, start with the Emerald SE or PE options supporting one or two full HD DVI/DP video heads with resolutions up to 1920 x 1200 - and migrate to 4K at your own pace by transitioning individual user groups when the need arises.

Virtualization
As more physical servers are replaced by virtualization allowing greater availability, better scalability, and therefore a higher return on investment. Emerald simplifies access to both physical and virtual servers with virtual machine support for VMware, Microsoft, and Citrix, using RDP, RemoteFX, and PCoIP. Emerald receivers connect to a virtual machine with additional hardware required and no training for the user.
Fail-safe operation
All Emerald 4K and PE transmitters and receivers feature copper or fiber connectivity through two flexible SFP+ slots.
Your 24/7 operation requires network resilience. Use the redundant network ports on the Emerald units to provide continuous, uninterrupted operation in the event one network experiences loss of service. Connect the endpoints either through two alternative direct links, a direct link, and a network connection, or two independent networks.
Network Requirements
For HD video, Emerald requires a standard Gigabit Ethernet network and possibly a 10 Gigabit aggregate switch, depending on how many endpoints you have. For a 4K pixel-perfect video, you'll need a standard 10 Gigabit Ethernet network with a 100 Gigabit aggregate switch. For both, the network infrastructure required by Emerald can be built with IEEE 802.3 standards-based components from Black Box or other manufacturers.

Industry-Leading KVM that Consumes Zero Rack Space
The Emerald ZeroU DVI Transmitter is a high-performance KVM solution that consumes zero rack space, enabling you to add more critical IT equipment to your data center. This transmitter works with the Emerald SE Receiver to provide a seamless desktop experience anywhere on a TCP/IP network while allowing the actual hardware to be securely housed in a corporate data center.
Emerald enables the same high fidelity experience of a desktop PC even for media-rich applications, like watching videos, photo editing with Photoshop, or 3D design with AutoCAD. Best of all, Emerald ZeroU is developed and manufactured by Black Box, so you can trust its build, performance, and reliability.
Visually Lossless Video
This powerful KVM solution delivers the high-definition video quality users today require to perform their jobs. It supports visually lossless DVI video up to 1920 x 1200.
Central Management
As with all other Emerald components, the ZeroU Transmitter is managed by our award-winning Boxilla KVM Manager and is fully interoperable with the Emerald SE Receivers.
Low Bandwidth Requirements
Emerald ZeroU provides outstanding KVM functionality without impacting your network performance. It requires less than 40 Mbps to provide 1080p video and fast switching speeds.
USB Powered
The ZeroU Transmitter won't clutter your workspace with wires. It is powered over USB, which eliminates the need for extra cables.
Low Smoke, Zero Halogen Cables
Cables on the DVI Zero U Transmitters are constructed with LSZH jackets. LSZH cables may be required in potentially poorly ventilated areas such as onboard aircraft, military vehicles, submarines, and ships.
