Product Features

  • Virtually instantaneous switching ensures seamless signal delivery.
  • Supports high-resolution DVI-D and USB-style keyboard/mouse, plus USB peripheral and audio options.
  • Maximum resolution of 1920 x 1200 at 60 Hz.


  • Uses CATx cabling, or single- or multimode fiber and extends signals up to 10 kilometers (6.2 mi.).
  • Connects via DKM modular interface cards and extenders (ACX1MT/ACX1MR), and compact extenders (ACX1T/ACX1R).
  • Available in 19" housings for high-density applications.
  • Virtually instantaneous switching and the transmission of high-quality DVI-D signals are what make the Black Box® DKM switching system a milestone in innovative HD video and peripheral matrix switching. Ideal for enterprise networks and mission-critical control/command rooms, as well as video production or broadcasting applications where HD video is everything. Many users can connect their KVM consoles to various multimedia sources (CPUs, servers, etc.), either locally or in a distant room or office via the switch.

    DKM is a scalable matrix switch that supports DVI-D and transmits USB Human Interface Device (HID), stereo audio, and RS-232 signals.

    Extend signals up to 460 feet (140 m) over CATx, up to 400 meters (1312.3 ft.) over multimode fiber, or up to 10 kilometers (6.2 mi.) over single-mode fiber.

    The DKM features hotkey controls and an on-screen display (OSD). Use the OSD to name connected devices and configure the system. A front-panel display with remote control is also available. Switching can be done remotely via the RS-232 serial interface or the TCP/IP interface.

    For ultimate plug-and-play support, the DKM has DDC read capability to receive true EDID information from the attached displays. The digital DKM does not need skew compensation like analog KVM switches do; the maximum video resolution is supported over the full distance.

    Setup and Operation Modes
    You can configure the DKM HD Video and Peripheral Matrix Switch in several ways. Connect the switch to CATx or fiber cabling, which then connects to the CPU/server with a local transmitter and, on the other side, connects to a receiver at the USB keyboard/mouse/monitors (user stations).

    Matrix (Crosspoint) Switching
    The DKM switch can be configured as a matrix (crosspoint) switch. Transmitters are installed at each of the CPUs, and DVI-D, serial, and audio signals go up to 10 kilometers (62 mi.) depending on the cabling used. Control the switch with the serial (RS-232) port or via the built-in Web interface. The matrix switch mode is especially ideal for post-production and digital signage applications.

    KVM Switch
    This DKM switch operates as a KVM switch in three configurations: single-head, dual-head, and quad-head. When used as a KVM switch, the DKM is cascadable: single-head, up to 1024 ports from one monitor; dual-head, up to 256 ports from two monitors; quad-head, up to 64 ports from four monitors.

    Share Mode
    Share Mode enables more than one user to have access to the same CPU at the same time. This is ideal in classrooms or conference rooms where an instructor or a presenter wants to use a laptop and a projector. It also gives an IT administrator access to a user's monitor for troubleshooting or applying updates.

    Additionally, the KVM switch enables port locking, meaning you can partner ports and ensure they switch in tandem. This way, when you switch CPUs, monitors being used in Share Mode follow automatically.

    Control Room Mode
    You can connect the switch to servers and monitors. The OSD enables the user to switch monitors between CPUs, and the hotkeys enable the user to switch using one keyboard/mouse for all the monitors.

    You can select from the list of available CPUs, and the users don't need to know the CPU's IP address to use the keyboard/mouse. Users can use Share Mode in this configuration also, giving access to more than one user at the same time.
