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)
