DL-DVI Vision IP – outputs dual-link DVI signals via standard IP-based layer 3 networks

The KVM-over-IP extender system DL-DVI-Vision-IP output the following signals:

  • Dual-link DVI video
  • Keyboard/mouse (USB and PS/2)
  • Audio + RS232
  • USB HID Generic

The system processes dual-link DVI image data pixel-perfectly and with very good hand-eye coordination. The maximum possible image resolution corresponds to a pixel rate between 25MPixel/s and 330MPixel/s. Signals are transmitted in compressed form using CAT cabling or optical fibers as well as over IP-based networks on layer 3 – even across network boundaries.

DL-DVI-Vision-IP is a console module (receiver), which is compatible with computer modules (transmitters) of the Vision-IP series. Combining DL-DVI-Vision-IP with a Vision-IP computer module allows users to operate their computers over large distances. By means of manual bandwidth management, the transmission can be adapted to a wide range of bandwidth requirements. Video, keyboard, mouse and control data is encrypted with AES-128.

Operating principle

To receive signals, DL-DVI-Vision-IP uses G&D’s KVM-over-IP technology. The transmission is based on IP networks over gigabit Ethernet (OSI model layer 3). The device provides a network interface for transmitting data, WebIF, configuration, monitoring, SNMP and updates. It is also equipped with a management network interface that provides all of the above functions in addition to data transmission.

For monitoring, DL-DVI-Vision-IP uses G&D’s proven monitoring and SNMP technology. The system is configured via web interface or OSD. Due to predefined IP addresses, plug & play is supported for the console module and a computer module of the Vision-IP series that are connected via existing network infrastructures or via CAT cables or optical fibers. Within the KVM-over-IP product family, the different extender variants are compatible with each other, allowing any mixmatching of different video interfaces on console and computer modules.

G&D’s KVM-over-IP technology can be used extremely flexible. The KVM-over-IP extenders can be operated in a matrix mode using an additional control unit, the ControlCenter-IP. This allows the distribution and sharing of signals within a LAN infrastructure. Users can also access their systems within the LAN network regardless of actual ranges. However, data transmission with KVM-over-IP technology is not compatible with classic KVM extenders from G&D.

  • High reliability

Screen freeze function

If the receiver loses the video signal due to a broken connection or a problem with the computer‘s graphics card, the Screen freeze function „freezes“ the image last displayed on the monitor. This status is highlighted by a red semi-transparent frame. The function is automatically cancelled when the display receives an active video signal.

Monitoring

With the Monitoring function, you can auto-output device status messages to Syslog servers or via SNMP. The web interface lets you monitor the device manually.

The monitoring function of the DL-DVI-Vision-IP queries the following values:

  • Status power supply unit (on/off)
  • Status temperature threshold device (in/over limit)
  • Status connection cables (ok/nok)
  • Status computer (on/off)
  • Status image signal graphics card computer (available/not available)
  • Status network
  • Status SFP modules (fiber variant)
  • Status interfaces transmitter and receiver
  • Freeze status
  • Type of display (local and remote)
  • Proactive monitoring of device status
  • Event reporting function (syslog or SNMP traps)
