Distributed system
With the distributed system multiple rendering machines are used. A rendering machine consists in an OmniBus
configuration of a rendering P
ROCESSOR
and one or two O

devices, in a Processor configuration it consists
just of one rendering P
ROCESSOR
. Each rendering P
ROCESSOR
is connected to the central device
by means of the
T

A sub-net.
With the distributed system, each rendering machine operates a rectangular array of projection modules within a
display wall. The actual subdivision into arrays depends on the requirements of each display wall (e. g. displaying
video). The following figure shows an example for a 10×5 arrangement:

Example for the assignment of rendering machines to projection modules
Additional information about the assignment of rendering machines to projection modules
can be found in section
6.1.6 Advanced configuration of TransForm A
.
The rendering machines are connected to the central P
ROCESSOR
within a separate sub-net (see also section
). Therefore the central P
ROCESSOR
is equipped with an additional network card. If also for the LAN connec-
tion an extra network card is used and not the onboard LAN adapter, then the network card with the lower
Ethernet address, respectively the higher PCI slot number connects to the LAN, the card with the higher Ethernet
address, respectively the lower PCI slot number connects to the sub-net.
