Arrangement of expansion cards
There are various ways how Barco’s expansion cards can be arranged in the PCI slots of the A
RGUS
O
MNI
B
US
de-
vices. The most important rules are listed below:
•
A graphic card with digital output transmits the data to an O
MNI
S
CALER
for additional video and RGB integra-
tion, or if no video or RGB sources are displayed it transmits data directly to the display wall. A graphic card
with analog output displays data always without O
MNI
S
CALER
. Data is transmitted between a graphic card and
an O
MNI
S
CALER
by means of the external Dual-DVI to Dual-DVI cable.
•
Data fed to the system through Q
UAD

, S
TREAMING
V

ARD
and D
UAL
RGB
I

can only
be displayed on the projection modules that are connected to the O
MNI
B
US
devices, in which these cards are
inserted.
•
Cards of the same type are inserted in consecutive order, but not all cards of one type must be in the same
O
MNI
B
US
.
•
The order of the different types of expansion cards in the PCI slots of one O
MNI
B
US
is first graphic cards then
O
MNI
S
CALERS
and finally input cards.
•
If not all slots are used for plugging in expansion cards, then these empty slots should be located between
graphic cards and O
MNI
S
CALERS
.
•
Graphic cards can be placed in different O
MNI
B
US
devices than O
MNI
S
CALERS
and the input cards belonging to
them.
•
If no graphic cards are used in an O
MNI
B
US
, then the O
MNI
S
CALERS
are inserted in the PCI slots with the lowest
numbers at the very left.
•
In a distributed system, it is necessary that the display wall is built of rectangular arrays. That means the
output to the wall of each O
MNI
B
US
that provides data for the display wall must feed a rectangular array.
•
In the rendering machine of a distributed system either one or two O
MNI
B
US
devices can be connected to the
rendering processor. If using one O
MNI
B
US
all kind of boards may be inserted into it. If using two O
MNI
B
US
de-
vices one is for graphic cards, the other for O
MNI
S
CALER
and input cards.
•
Also other restrictions may apply. If in doubt contact your authorized service personnel.
Examples of some significant configurations
The examples below cover different kind of configurations to point up the rules given above. The following ab-
breviations are used:
•

The schematic drawings of the O
MNI
B
US
devices show always the view on the back of a device. To keep it clearly
arranged, only the 18 free available PCI slots of an O
MNI
B
US
are plotted. The display wall is shown from the front!
