Hardware configuration
For best performance the plugging order of expansion cards in the O
MNI
B
US
A12 should be considered. Cabling is
explained in the service manual; anyhow for plain video mode the following exceptions should be made:
Having an O
MNI
B
US
A12 with six or less expansion cards:
•
Only the PCI slots with odd numbers are used.
•
First the graphic cards are inserted in ascending order in each second PCI slot, beginning with the PCI slots
with the lowest numbers at the very left (slot 1, 3, 5, …)
•
The input cards are inserted consecutively in the following slots with odd numbers (slot ..., 7, 9, ...)
Having an O
MNI
B
US
A12 with seven up to twelve expansion cards:
•
The expansion cards are inserted as described in the service manual with the only difference that the
O
MNI
S
CALERS
are omitted.
Respect the other general instructions for insertion of expansion cards given in the Service
manual!
Make sure that any actions at the open device are carried out by qualified service
personnel.
These rules are a suggestion for best performance for an O
MNI
B
US
A12 in plain video mode. For
special requirements also some subtle configurations might exist. In case of doubt contact the
Barco support; please refer to section
.
Functionality of video/RGB windows
Video windows of plain video behave the same way like standard video using O
MNI
S
CALERS
, except for the follow-
ing items:
•
Upscaling
Video data can only be displayed 1:1 or downscaled.
Downscaled window content requires less bandwidth. Therefore only the actually displayed pixels must be
considered when calculating the bandwidth.
If anyhow the video window is dragged larger than 1:1, then the video itself will remain as 1:1 image cen-
tered in the window surrounded by black pixels.
•
Zooming, Cropping
Zooming and cropping is only useful as long as the video window is not larger than the standard size.
•
Pixel Format
The pixel format is by default 16 bit RGB.
The
Scaler settings dialog box
cannot be displayed and the pixel format cannot be selected.
•
If using multiple O
MNI
B
US
A12 devices, a video can only be displayed on the projection modules that are
connected to the graphic cards of that device that contains also the input card of that video.
Genlock
is not supported with plain video.
