* Composite sources can physically connect to level 3 when boards 1 & 3 are connected via the cable assembly.
Depending on how the internal boards are cabled/jumpered, the unit can be used in
different configurations (each is discussed in the following subsections). Refer to the
flowchart below to determine which configuration to use (based on the source types
in the system).
NOTE: Crestron recommends the out-of-the-box configuration, because it allows
for the distribution of a large number of sources with the greatest flexibility and there
is no need to open the unit. The other configurations permit a greater number of
sources, but are not as flexible. The other configurations also require cabling of
boards and possibly the removal of jumpers.
Flowchart: Determine the Configuration
Determine the configuration based
on the sources in the system.
Are there more
