Features & Applications

The Zero-U KVM Switch System allows you to control up to 64 computers without consuming rack space. The switch frees up valuable space by eliminating large KVM switchboxes and bulky hard-to-manage coax cables.

The PRIMUX system consists of two components: the User Station that connect to a keyboard, monitor, and mouse, and Host Adapter that connect to a server. Up to 64 Host Adapters can by daisy-chained together, providing user access to up to 64 servers. The User Stations and Host Adapters can be located as far as 305 meters from each other via CAT5 UTP cable.
  • A single, inexpensive CAT5/5e/6 UTP cable replaces bulky KVM cables.
  • Ideal for hazardous/unsecured environments. User station can be located up to 305 meters from servers.
  • Easy to install and use with plug-and-play functionality.
  • Provides a simple daisy-chained wiring configuration.
  • Hot-swap components with no disruption of server operation.
  • Crisp and clear 1024x768 video resolution at 305 meters, higher resolution supported at shorter distances.
  • Keep-alive keyboard/mouse emulation for flawless operation.
  • Interconnect multiple servers at different locations throughout a building. Servers can be of the same or differing platforms (PS/2, SUN or USB).
  • Dedicated microprocessors prevent CPUs from locking up, ensuring reliable control.
  • OSD provides fine tuning for optimal video quality.
  • Color-coded LEDs on both the local and remote units indicate power status and verify communication between the units.
  • Automatically adjusts the video quality to compensate for varying lengths of Cat5/5e/6 cable.
  • Configuration is saved and restored even if unit loses power.


User Station
  • Female 15-pin HD connector.
  • A multiscan VGA monitor is required to display the different video outputs from different platforms.

Control Methods

On Screen Display (OSD)
  • Locate and select computers by name, comment, index or ID.
  • Use keyboard or mouse to operate the switch from menus superimposed onto the monitor.
  • Displays the platform, name, and power status of the daisy-chained computers.
  • Names can be up to 16 characters long.
  • Allows color skew compensation and video compensation fine tuning for optimal video quality.
  • Help Screens assist users with OSD.
  • Modify the size and position of the OSD.
  • OS- and software-independent.
  • Security
    • Add or remove authorized users.
    • Set individual user names and passwords for each user.
    • Administrator can enable or disable all security features and select which computers each user can access.
Front Panel Interface
  • Locally change ports with front panel buttons.
  • Provides eight "favorites" buttons allowing the user to select frequently used computers for quick access.
  • Scan or Command Modes are available from the keyboard.
  • Scan Mode automatically and sequentially displays the video from each powered-on computer. Duration of display can be 2-255 seconds.
  • Command Mode allows the user to give instructions to the switch through the keyboard. Keystrokes are not passed to the computer.
  • Use the keyboard to command the user station to select ports or configure the Scan delay. The mouse also fully works in command mode.
  • Type <Ctrl> + <`> (or <Compose> + <`>) to go into Command Mode. ("`" is the accent mark located on the same key as the tilde "~".)
  • Press <Esc> to leave Command Mode and return to Normal Mode or Scan Mode.
