Product Features

  • Place your keyboard, monitor, and mouse up to 1000 feet (304.8 m) from a CPU or ServSwitch.
  • You also can send serial port data up to 1000 feet (304.8 m).
  • Compatible with printers, touch screens, and more!


  • To convert your USB-style keyboard and mouse signal to PS/2, order the USB to PS/2 Converter (KVUSB).
  • Rackmountable.
  • Fully adjustable video equalization.
  • Surge protection defends CAT5 side against spikes and surges!
  • Listen to near-digital-quality audio from the CPU via speakers attached to the remote unit (single access).
  • Dual-access model is also available.

  • This ServSwitch™ CAT5 KVM Extender with Serial Extension and Stereo Audio Support enables you to place your VGA monitor, keyboard, mouse, and a serial device (like a modem, printer, or touch screen) as far as 1000 feet (304.8 m) from a CPU. Plus, it enables you to place audio devices such as speakers, microphones, and headphones up to 1000 feet from the CPU.

    The extender comes in a kit that includes local and remote units, which are connected with a single CAT5 cable. All keyboard, mouse, video, serial, and audio signals are fully buffered to ensure consistent remote operation of your PC.

    Our single-access model is designed to perform basic KVM and serial extension as well as audio extension.

    Setup is simple. Connect the local and remote units to each other and your equipment. Then adjust your video compensation. That's it! The extender is easy to operate and requires no software.

    Because the extender performs complete PS/2® keyboard and mouse emulation, you can boot the PC without having a keyboard or mouse attached to it.

    It features fully adjustable video equalization to compensate for the loss of image quality caused by the signal passing through long cable runs.

    The extender is compatible with Microsoft® IntelliMouse® and other wheel mice.
    This product works with:
  • CAT5 100-MHz Solid-Conductor Bulk Cable, 4-Pair (EYN840A, EYN860A)
  • 19" Rackmount Kit for ServSwitch CAT5 KVM Extenders (RMK19U-R2)
