The NTI XTENDEX ST-C5USBV USB KVM extender provides local and remote KVM (USB keyboard, USB mouse and VGA monitor) access to a USB computer or NTI KVM switch up to 1,000 feet using CAT5/5e/6 UTP cable, which overcomes the USB five meter limitation.

Each ST-C5USBV consists of a zero-U local unit (connects to a computer, and provides local keyboard, monitor and mouse connections) and a desktop remote unit (connects to a keyboard, monitor and mouse or the inputs of an NTI switch). The local and remote units are interconnected via CAT5/5e/6 cable.

  • Supports local and remote access.
  • Automatically adjusts the video quality to compensate for varying lengths of CAT5/5e/6 cable.
  • Simple On Screen Display (OSD) menus allow users to configure the extender, adjust for video skew, and fine-tune video quality for optimal video resolution.
  • Maximum 1024x768 video resolution at 1,000 feet; higher resolutions are supported at shorter distances up to 1920x1440.
  • Keyboard and mouse are hot-pluggable.
  • Keep-alive keyboard/mouse emulation for flawless operation.
  • Color-coded LEDs on both the local and remote units indicate power status and verify communication is established between the units.
  • Built-in surge protection.
