8.9 - SUB-FIXTURES
Sub-fixtures do not have a Tessera interface and so cannot be connected directly to a Processor
or XD output. Instead m ultiple fixtures are connected to a single power/control box. These
fixtures are represented in the Tessera system as sub- fixtures. The power/control boxes are
called root nodes.
Each root node contains a R2 receiver card, and like norm al panel-type fixtures are connected to
the rest of the system over daisy-chained Gigabit Ethernet. Root nodes connect to sub-fixtures
using a proprietary data/power connection.
Tessera SX40 processor includes support for sub- fixtures from firm ware version 2.3 and
upwards, sim ilar to Brom pton's HD processors, a m axim um of 2000 fixtures, sub-fixtures or a
com bination of both can be used per processor.

N OTE When calculating processor pixel capacity, sub-fixtures with less than 64 pixels are
calculated as the sam e as 100 pixels.
N OTE As on other processors, the fixture lim it on Tessera SX40 also applies to sub-fixtures.
(I.e. 2000 fixtures, sub-fixtures, or a com bination of the two.) Sub-fixtures which are
sm aller than 64 pixels in one or both dim ensions have these dim ensions rounded up
to 64 when calculating the processor load. (I.e. A 1 x 100 pixel sub-fixture has the
sam e load as a 64 x 100 pixel panel.)
