Connecting Multiple Control Units - Pliant Crewcom CCU-22 Operating Manual

Connecting Multiple Control Units

By default, the first Control Unit added to the CCF is automatically assigned the Master sync priority. Every CCF must
contain one master Control Unit, which is set through CrewWare. Secondary and Tertiary sync priority assignments
are not currently operational.
Caution: Loading or having a previously loaded CCF on any CU other than the Master CU will cause a
configuration malfunction. See
and resolving this issue.
CrewNet supports up to 4 Control Units. These additional Control Units can be connected to the network via an
available CrewNet port on another Control Unit or a CrewCom Hub. No Control Unit additions can be made via an RT's
CrewNet port. Multiple Control Units may only be connected together (i.e., daisy-chained) when they are connected
directly from the Master Control Unit. A single Control Unit may be connected from a CrewCom Hub; this configuration
is not considered to be daisy-chaining the CUs. See the images below for examples of acceptable and unacceptable
multi-CU system diagrams. See
CrewWare.
