Pro KM Switch
Deliver a seamless productive and desktop experience
when simultaneously working with multiple workstations
or across multiple secure networks

Pro KM switches

There are two common scenarios when using professional KVM switches including multi-displays with and without video switching.

KVM Switch models:
K4u+ K4vu
Switch type KM Switch KVM Switch
Connect up to 4 PC/Workstations · ·
Secure keyboard/mouse, USB & Stereo Audio Switching · ·
Video Switching ·
K4u+ Switch

There are many scenarios were users need a multi-display configuration that connect from a single keyboard and mouse to multiple workstations or desktops that may be local (desk-side), remote or virtual.

  • K4u+ Deployment Example Legend
    A: Virtual Desktop B: DXP4 or DXH4 KVM Extender PCIe card in a PC or workstation
    C: Blade Workstation / Virtual Blade Workstation D: DXZ4-series quad head zero client
    E: DXZC-series dual head zero client F: Local PC/Laptop/music player
    G: K4u+ 4 channel keyboard, mouse and stereo audio switch H: Headphones/speakers (powered)
    I: Hot-plugged device (USB)

 

K4u+ Key Features and Benefits
  • Multi-level Network Security
    Scenario Commonly used by: Deployment example: 
    Users are required to work on workstations or desktops that are connected to networks with different security levels. Government, Healthcare, Defence, Intelligence, Military Analyst using K4u+ and zero clients to work on any network from non-classified, SIPRNet, NIPRNet to JWICS or Non-classified, OFFICIAL, SECRET, to TOP SECRET
  • Workflow Productivity / Cost Effective Infrastructure
    Scenario Commonly used by: Deployment example: 
    Workflow requires access to multiple workstations or desktops running different applications and different platform performance levels. Design and simulation, Oil & Gas, Media & entertainment Artist using K4u+ and zero clients to access different pre-post production video editing workstations:
    Pre-production video and storyboard tools on a low-mid range physical or virtual workstation
    Post-production design and editing tools on a mid-range physical or virtual workstation.
    Post production rendering and transcoding on a high-end physical or virtual workstation.
    General office applications on a virtual desktop or cloud managed desktop
  • Meet Application Licensing restrictions
    Scenario Commonly used by: Deployment example: 
    Application, software or hardware licensing restricts use to a particular platform, or prevents other software being installed on the same workstation or desktop. Design, simulation software
    Financial services software
    Medical imaging/diagnostic systems
    Trader working on Bloomberg workstation, Thompson Reuters workstation and a virtual or cloud desktop for general office applications.
  • Workstation Performance / Stability
    Scenario Commonly used by: Deployment example: 
    Increase workstation performance and stability while reducing IT support effort by separating applications and potentially conflicting drivers onto different workstations/desktops. Media & Entertainment,
    Engineering/manufacturing
    IT segmentation of design and simulation applications on different workstations to isolate applications and/or drivers and updates and providing a virtual desktop or cloud managed desktop for general office applications.
  • Connect 4+ computers with no distance limitations

    Amulet Hotkey’s K4u+ KM switch allows the connection of up to 4 Workstations/Desktops to a single keyboard, mouse or peripheral set. Cascade switches to connect to more than 4 computers.

    Combine K4u+ with Zero Clients for no distance limitations
    While the K4u+ can be connected directly to workstations at the user’s desk, it is also compatible with Amulet Hotkey Zero Clients for maximum flexibility and efficiency allowing connections to remote physical or virtual workstations, virtual desktops and/or cloud desktops. Each of the remote workstations or desktops can be securely accessed within the office, across the country, or continent-to-continent.

  • Mission critical design

    The K4u+ is designed from the ground up for mission and business critical environments, and includes features such as redundant power management, power cord lock and robust metal enclosure.

    In-house design and manufacturing for quality control
    Amulet Hotkey takes a comprehensive approach to ensure your success from planning through deployment, management and support. This starts with Amulet Hotkey’s long standing commitment to in-house product design and manufacturing which provides a level of control and security lacking in vendors that rely on remote contract manufacturing. We understand our KVM Switches from the core PCB, thermal and EMI design, manufacturing line, packaging and system architecture to configuration and deployment which enables an enhanced level of quality and technical support.

    ISO 9001:2015 Quality Certification Amulet Hotkey is deeply committed to achieving consistent high-levels of quality, reliability, security and customer service. Amulet Hotkey has been accredited by the British Assessment Bureau for the latest ISO 9001:2015 Quality Management System Standard certification. Certificate Number: 212920.

  • Extensive Security

    The K4u+ is TAA compliant and incorporates our no compromise KeyStop™ architecture that prevents channel cross-talk or key-stroke recording/key logging. KeyStop guarantees zero channel cross-talk and eliminates buffered key codes to improve security in deployments such as multi-level security access where channel separation is required. Also, the K4u+ supports smart cards and automatically manages the card reader connection to the attached workstations/desktops to simplify the login process.

  • Boost Productivity and Efficiency

    Seamless workspace and Mouse Point automatic channel switching
    The K4u+ includes many features to boost user productivity and efficiency including enabling the creation of a seamless desktop experience across multiple workstations and/or desktops using Mouse Point. Mouse Point automatically switches from one workstation to another by simply moving the cursor to another screen. Mouse Point supports flexible monitor layouts up to 32 monitors, which can be user configured through an intuitive graphical interface.

    Instant channel switching
    The K4u+ supports instant channel switching by incorporating USB emulation and hosting capability.

    SaverSync automatic display management
    Also, the K4u+ screen SaverSync ensures that all of the user screens remain active to display vital data and an efficient workflow, while still adhering to corporate power reduction / green computing policies. SaverSync ensures that all displays across each workstations remain active while there is activity on any channel. Screen savers only activate after there is no keyboard/mouse inactivity across all channels for a period of time.
