applications.
CrewCom Devices
The following is a list of available CrewCom devices. For more information on each of these products and their
configuration capabilities, visit the specific device's overview pages linked below.
Control Unit
(CU) – the 1RU foundational element of the CrewCom system that establishes the CrewNet-based
l
infrastructure while also providing external connections to common established intercom systems. Unlike
traditional BaseStations, the CU contains no radio and is frequency agnostic, which sets the groundwork for a
multi-frequency capable system. For maximum flexibility, any CU can access, control, and monitor any active
device across CrewNet. The CU is available in a "CCU-22" or "CCU-44" model, which simultaneously support
up to (2) 2-Wire and (2) 4-Wire or (4) 2-Wire and (4) 4-Wire intercom connections, respectively.
Radio Pack
(RP) – the direct portable wireless communication device connecting individual CrewCom users to
l
the CrewCom system. Each RP provides full duplex audio communications and, through customized function
buttons, General Purpose Output (GPO) control and event logging. The RP requires a connected headset and
access to a Radio Transceiver on the CrewCom system. Devices are available in 2.4GHz and 900MHz bands as
well as two and four volume/talk button configurations.
Radio Transceiver
l
and its corresponding antennas, enabling RF communications to CrewCom Radio Packs. Using the CrewNet
network as the system's backbone, RTs can be positioned throughout a wide coverage area by being linked
back to a Control Unit either directly or through a Hub(s). Connectivity is accomplished using either Cat 5e (or
greater) or Single Mode Fiber (SMF).
Copper Hub
– a CrewNet-based device with eight ports to allow extended interconnection for a variety of
l
CrewCom hardware. Ports one through seven are copper (RJ-45, Cat 5e, or greater); port eight can be either
an additional copper port or a duplex LC Single Mode Fiber port, but only one may be used at a time. The Hub
provides for extensive system expansion and flexibility.
Fiber Hub
– a CrewNet-based device with eight ports to allow extended interconnection for a variety of
l
CrewCom hardware. Ports two through eight are duplex LC single-mode fiber ports; port one can be either an
additional fiber port or a copper port (RJ-45, Cat 5e, or greater), but only one may be used at a time. The Hub
provides for extensive system expansion and flexibility.
(RT) – a CrewCom radio device that houses a transmitter and receiver (2.4GHz or 900MHz)
