High-density KVM Extender Host remote Workstation solution

Rackmount KVM Extenders are a high-density solution to provide remote access to PCs, laptops and workstations where it is not possible, or desirable, to install a Remote Workstation PCIe Card or workstation access software. The DXR-H4 KVM Extender provides a non-intrusive remoting solution for workstations with demanding security and graphics requirements.

Key Features and Benefits

Key Deployment Scenarios

The DXR-H4 KVM Extender solution can be used to provide remote access to workstations with demanding graphics requirements including:

  • Secured workstation, laptop or closed system where it is not possible to install 3rd party software and there is no physical access to the workstation PCIe bus slots.
  • Deployments where software remote access solutions do not meet the demanding graphics or user experience performance requirements.
  • Medical or industrial equipment where opening the Workstation is not supported by agreements/warranty.
  • Software or other legal agreement where additional equipment installation is not supported.
Secure and Non-Intrusive Remote Access

Amulet Hotkey provides a Rackmount KVM Extender solution that enables remote access to the workstation without the need to install a remote access card or software.

External connection only using standard cables.

The DXR-H4 KVM Extender cards are completely non-intrusive: PCs, laptops and workstations are connected using only standard external cables. There is no remote access software required on the host workstation, so DXR-H4 cards can be used to remote any PC, workstation or legacy system with digital video outputs, USB keyboard/mouse inputs and stereo audio output/microphone inputs.

Optimized for Scalability and No Remote Access Distance Limitations

No distance limitations between KVM Extender host and client endpoints

The DXR-H4 uses KVM-over-IP technology based on the industry-standard Teradici PCoIP remote display protocol. Users can connect over standard IP networks locally, from any meeting room, from home, across the country or continent-to-content.

Contact us for more information on options to configure networks and tune PCoIP configuration settings to optimize the user experience.

Data center optimized for scalability

The DXiP Rack 3U system can hold up to 12 DXR-H4 KVM Extender Host Cards to remote up to 12 quad display workstations. Flexible cabling options with short 1m cable and 2.8-3m cable sets to connect to computers and workstations.

Designed for Mission Critical Environments

The DXiP Rack is designed and manufactured for mission and business-critical environments with features such as chassis dual redundant power supplies. The DXR-H4 and DXT-H4 support quad displays up to 1920×1200 resolution or dual displays up to 3840x2160.

Access your workstations remotely from across the office, from home, across the country or continent-to-continent.

Ultra-High Security

Unique features to enhance security

DX Series Zero Clients provide a highly secure and stateless client endpoint with no x86 processor, no hard drive, no local storage, no local GPU and no drivers – all of which reduce the attack surface.

DX Series Zero Clients provide many advanced and unique features such as:

  • Intelligent USB lockdown
  • IEEE 802.1x network authentication, fiber networking
  • Engineered for EMI protection
  • Optional embedded smart card readers
  • Advanced security algorithms such as 256-bit AES and NSA Suite B cryptography
  • TEMPEST model options

Transmit display pixels and not application data

Protect corporate or government information by moving workstations into a data center. Use centralized workstations, virtual workstations, virtual desktop and/or cloud managed desktop solutions to keep sensitive information within the data center and only send encrypted display pixels to the DX Series Zero Client.

Flexible Zero Client and Mobile Remote Access Client Endpoint Options

Use Amulet Hotkey zero clients for the best performance and highest security client solution. While software clients may not provide the same level of performance, they provide the ability to connect from mobile devices such as laptops, tablets or smartphones.

World-class Quality and Support

Amulet Hotkey’s long-standing commitment to in-house product design and manufacturing provides a unique level of control and security. In-house design control of the circuit boards, thermal and EMI designs, manufacturing processes, and system architecture enables an enhanced level of quality and technical support.
