SYNC IN Port (RJ-45 or Fiber):
SYNC IN allows the Control Unit to receive and use a sync source (available
CrewNet connection) from another CrewCom system, but this connection is not required to be part of any
system configuration. This particular connection can support either an RJ-45 copper (Cat 5e or greater) port or
a Single Mode Fiber (duplex LC connector) port, but not both at the same time. See
for more information.
Important
: Sync is not accomplished by connecting between two Control Units' SYNC IN ports;
rather, it is done by connecting between a sync source's CREWNET port and the receiving
system's SYNC IN port.
Important
: No audio or controls are shared between synced systems.
Each Sync In port’s status LEDs indicate the status of the sync link. (See
"Control Unit LEDs" on page 45
.)
CCU-22
The CCU-22 model has the same controls and functions as the CCU-44, with two exceptions: the 2-Wire and 4-Wire
Intercom Connections, which are outlined below.

2-WIRE Intercom Port (x 2):
The Intercom Channel ports (1 and 2) allow the user to connect the Control Unit
to 2-Wire external intercom systems. The XLR-3M/F 2-Wire intercom ports interface with Clear-Com, RTS,
AudioCom (Balanced), and other compatible intercom systems. The pairs of XLR-3M and XLR-3F are
electrically identical—including the grounds—but the grounds of the two channels are electrically isolated
from each other. Each connector pair is transformer isolated. The 2-Wire Intercom settings can be adjusted
under the
Wired Settings
menu or via CrewWare. (See
"2-Wire Intercom Connectivity" on page 56
.)
