Control Unit

The CrewCom Control Unit (CU) is a rack-mount device built to withstand the rigors of road use and rental
applications. It is the foundation for CrewNet. The CCU-44 is an 8-intercom-port CU with the ability to support (4) 2-
Wire and (4) 4-Wire ports simultaneously, providing eight intercom inputs/outputs. The CCU-22 is a 4-intercom-port
CU with the ability to support (2) 2-Wire and (2) 4-Wire ports simultaneously, providing four intercom inputs/outputs. A
separate Radio Transceiver (RT) is required for RF communications. The CU is capable of supporting all models of
CrewCom RTs at the same time (2.4GHz or 900MHz).

however, pressing and holding the talk button will cause the button to act as a momentary switch. (See
