g. The D2CIM-DVUSB-HDMI CIM does not support HDCP or embedded audio. For some servers, the “DVI Compatibility
Mode,” which provides a DVI compatible video signal, will provide improved video quality. This can be set on the Port
Configuration page.
h. The D2CIM-DVUSB-DP does not support DPCP or embedded audio.
2. Dual Video Support:
a. Both the primary and secondary ports should use the same video resolution and port permissions.
b. The client, the Dominion KX II and the target server should all be configured with the same Primary/Secondary port
monitor orientation. Orientation is the spatial relationship of the primary and secondary video displays.
c. For best results, the Primary Port should be the port with (1) the left-most display (horizontal orientation), or (2) the top
display (vertical orientation). Mouse settings, virtual media, Smart Card and digital audio are then controlled from the
Primary Port.
d. Consult the documentation for recommended mouse modes by operating system. The type of extended desktop
supported by the video card and/or OS is an important consideration. The mouse mode used for dual video may be
different from your single video use.
e. The use of single mouse mode is not recommended in full screen mode with a single client monitor.
f. Since two simultaneous KVM sessions are launched, a KX II model supporting 2 or more remote users is required. For
multiple servers with dual video ports, an 8 user switch is recommended: DKX2-808 or DKX2-832
3. SNMPv3:
a. Must be enabled on two pages on the user interface:
b. Device Settings > Event Management – Settings > SNMP Traps Configuration
c. Device Settings > Device Services > SNMP Agent Configuration
4. SSL Certificate Vulnerabilities. Customers running vulnerability scans on the KX II may see violations related to the default
SSL certificate installed at the factory. To remove these vulnerabilities, customers should install their own SSL certificate, either
self-signed or from a Certificate Authority.
Release 2.4 Important Notes and Information:
1. For the Digital Audio over IP feature:
a. The D2CIM-DVUSB CIM is required for the audio feature.
b. The Release 2.4 CIM firmware versions of 3A88 or 5A88 (or greater) is required for the D2CIM-DVUSB. When
upgrading to the Release 2.4 firmware, all attached CIMS will be upgraded. For non-attached CIMs, you can use the
“CIM Firmware Update” feature to upgrade these CIMS.
c. Audio performance is dependent on the available network bandwidth. Up to 1.5 mbps is required for CD quality
playback (44,100Hz, 16 bits per sample, 2 channels). Round trip network delays exceeding 50 milliseconds or more
and packet loss of 1% or greater will result in poor audio quality. In this case, we recommend selecting an audio
format that requires less bandwidth. There may be slight breaks in the audio stream based on video processing and
other CPU intensive activity.
d. Since audio utilizes the virtual media connection, when audio is enabled, either a smart card or a mass storage device
may be used, but not both. An as an audio session uses bandwidth over the “virtual media” channel, this may affect
the performance of virtual media transfers.
e. When making the audio connection, the USB interface will be re-enumerated, such that a virtual media connection may
be interrupted and/or the smart card session may need to be re-authorized.
f. From a single client workstation, only one simultaneous audio session is supported.
