Product Features

  • An all-in-one KVM extension solution for dual-head VGA video, stereo audio, RS-232 signals, and multiple USB ports.
  • Transmits signals as far as 400 feet (121.9 m) to a remote location over four CATx cables.
  • Does the job of multiple extension products. Eliminates the need for multiple boxes locally and remotely.


  • Ideal for healthcare and hospital settings.
  • Includes a rackmountable transmitter unit and a wallmountable receiver.
  • Simplifies control and saves space, particularly in cramped console areas.
  • Uses inexpensive, easy-to-install CAT5e or CAT6 cable for signal extension.
  • Integrated skew compensation. Special low-skew cables aren't needed.
  • Enables you to separate a CPU from a KVM console but still enjoy 1920 x 1200 video.
  • Supports dual-display VGA video and stereo audio (amplified or line level).
  • Ideal for multimedia studio and imaging applications requiring dual-video extension.
  • Also extends bidirectional RS-232 serial signals and independent USB ports.
  • Receiver unit has four general-purpose USB ports, as well as two dedicated USB ports.
  • Dedicated ports support high-bandwidth devices, printers, and similar USB peripherals.
  • Supports KVM console access on both transmitter and receiver units.
  • Receiver has an input/output hood cover for protection. No need for a utility box.
  • Buffered local looped outputs for two monitors, a USB keyboard and mouse, and speaker output.
  • Features powered audio output for driving passive speakers.
  • All USB ports support hot plugging of peripherals.

    The ServSwitch Universal KVM Extenders do the job of multiple extension products. This combination of transmitters and receivers (also available separately, ACU8000A-T and ACU8000A-R) eliminates the need for multiple local and remote boxes.

    The Universal KVM Extenders extend dual-head VGA video, audio, and serial signals, plus three independent USB ports, all up to 400 feet (121.9 m) over CATx cable.

    The ServSwitch™ Universal KVM Extender Kit includes a transmitter and a receiver. Working together, they perform the actions of several high-end products:
  • A dual-head KVM extender
  • A dual-port USB extender
  • A video skew compensator
  • A video test pattern generator
  • An audio amplifier
  • And an EDID emulator.

  • The rugged transmitter can be mounted in rack or cabinet (all connections are on the rear); whereas the receiver unit can be mounted on a wall.

    Even better, the receiver features a protective plate that guards connectors from dirt, debris, and the accidental unplugging of cables—essentially eliminating the need for a utility box at a remote location. Tie downs provide strain relief for cable connections.

    With this KVM extension solution, you can use four CATx cables to link a console with a VGA monitor and USB keyboard/mouse to a CPU or server up to 400 feet (121.9 m) away—and get clear remote video even at the maximum distance. No repeaters are needed.

    Provides flexible video and audio connectivity
    The extender supports VGA through UXGA, and has two VGA ports for dual-video input and two VGA ports for looped local monitor connections on the transmitter unit plus dual VGA ports on the receiver.

    Built-in skew compensation automatically corrects RGB convergence on both video channels, even over long CAT6 runs. This eliminates the need for special low-skew UTP cabling—use the cable you already have installed.

    In addition, the extenders feature a built-in test pattern generator to compensate for longer cable lengths, or high frequency gain, and skew correction. Simply press the front-panel buttons to adjust either the high-frequency compensation (HF gain) or the red, green, and blue signal alignment.

    Built-in EDID support enables the CPU's video card to provide the most common resolutions to your monitors, even if the monitors aren't detected, aren't LCD monitors, or don't support EDID. The transmitter features a DB15 port for powered audio and a looped DB15 powered audio port for plugging in and amplifying passive speakers. For audio on the remote, there is a powered DB15 output jack and a 3.5-mm mini stereo (line-level) audio jack.

    A built-in USB hub plus dedicated USB port extension
    These extenders support USB speeds of 1.5 Mbps (USB 1.0) and 12 Mbps (USB 1.1), and even USB 2.0 devices as long as they are backwards compatible.

    The transmitter features a general-purpose USB port routed through an integrated hub to give you two local USB outputs. Use these ports to locate USB peripherals near your computer or local console. In addition, the transmitter extends USB USB signaling across the CATx link to communicate with a device plugged into one of the four general-purpose ports on the receiver end. For instance, you can use the first two ports for a remote keyboard and mouse, and the third and fourth USB ports for touch screens or other USB peripherals. The receiver features four general-purpose USB ports, plus one or two dedicated USB ports (DR1 and DR2). Signals from these dedicated "direct extension" USB ports does not pass through the transmitter's built-in hub. Instead, two USB ports on the local PC are extended directly over CATx to corresponding USB ports on the receiver side. This means the PC's USB port behaves exactly as if it were connected directly over CATx to corresponding USB ports on the receiver side.

    Additionally, the USB ports are hot-swappable.

    The transmitter provides local support for the dual-head video, audio, and USB. Other signals are routed to the receiver without local support.

    As with all our KVM extension solutions, the ServSwitch Universal KVM Extenders enable you to keep your computer and valuable data in a locked, secure room and manage it remotely.
