 Single-USB CIMs (D2CIM-VUSB) – a single USB plug

 Dual-USB CIMs (D2CIM-DVUSB and D2CIM-DVUSB-xxx) – two USB plugs

There are two types of video supported:

 Traditional, analog VGA video

 Digital video formats: DVI, HDMI and DisplayPort

 Dual Virtual Media USB CIMs (D2CIM-DVUSB & D2CIM-DVUSB-XXX)

Dual USB CIMs have two USB connectors and support both VGA and the new digital video

formats.

They should be purchased by customers who want these digital formats and/or customers wanting

enhanced features: virtual media at the BIOS level, for audio, tiering and/or Smart Cards,

including the US Government’s Common Access Cards (CAC).

The available dual USB CIMs include:

 D2CIM-DVUSB– enhanced, dual USB, virtual media CIM for analog, VGA video

 D2CIM-DVUSB-DVI – enhanced, dual USB, virtual media CIM for DVI-D, digital video

 D2CIM-DVUSB-HDMI – enhanced, dual USB, virtual media CIM for HDMI, digital video

 D2CIM-DVUSB-DP – enhanced, dual USB, virtual media CIM for DisplayPort, digital video

Advanced KVM features such as virtual media rely on the power of the USB protocol. But some BIOS

do not support the USB specification well enough for these advanced features. We have seen a large

diversity of BIOS with various limitations and deviations from the USB specification.

The D2CIM-DVUSB has two USB plugs, one for keyboard/mouse and one for virtual media. This

enables many additional server BIOS to access virtual media drives. The black connector on the

DVUSB CIM is used for keyboard and mouse. The gray connector is used for virtual media. Keep

both plugs of the CIM connected to the device at all times. The device may not operate properly if

both plugs are not connected to the target server.

 Digital CIMs (D2CIM-DVUSB-DVI, D2CIM-DVUSB-HDMI, D2CIM-DVUSB-DP)

Customers with servers, PC’s or MAC’s using the DVI-D, HDMI, or DisplayPort digital video formats

should use one of the new digital CIMs. These CIMs will support the KX III standard video resolutions

of up to 1920x1080, including widescreen formats.

DDC/E-EDID is supported by the digital CIMs with the “preferred timing mode” set by the Dominion

KX III administrator. This is the preferred/native/default video resolution, called the “Display Native

Resolution” on the KX GUI. The default is 1280x1024@60hz, but this can be changed by the user on

the Port Configuration Page for each port. This communicated to the server to tell it what video

resolution to use, however not every server/OS/video card will use it. See the release notes and

documentation for more information.

Only Single Link DVI and HDMI are supported. For HDMI, HDCP (high bandwidth digital copy

protection) is not supported. Digital audio is supported over USB as in previous releases, not

embedded in the HDMI or DisplayPort signals.

 DVI Compatibility Mode for HDMI CIMs

Servers may output video using limited range RGB in accordance with HDMI standards. The result is

that the video may be too dark or light. We have seen this with Dell Optiplex servers at 1920x1080.

Also for Apple’s Mac Mini using the HDMI port.

A ‘DVI Compatibility Mode’ check box is available on the GUI for each port. This mode will provide the

DVI E-EDID to the target upon request. The server will output a DVI compatible video signal. This

improves the video quality for some servers.
