Pliant Technologies' CCU-22 is the Control Unit component of their CrewCom proprietary crew network communications system.

The foundational element of the CrewCom system, the Control Unit (CU) establishes the CrewNet-based infrastructure while also providing external connections to various common, established intercom systems.

By design, the CU contains no radio and is frequency agnostic, so it can therefore control and monitor any device across CrewNet regardless of radio frequency bands being employed.

The Backbone: CrewNet™

CrewNet is a newly-developed, robust and reliable proprietary network designed specifically for the demands of critical communication environments. It is the backbone for interconnection between CrewCom devices, which is key to the decentralized network architecture. CrewNet is capable of deploying a CrewCom system over a very large coverage area with Cat 5e (up to 100 m) and/or Single Mode Fiber (up to 10 km).

• Each CU (additional CU units sold separately) supports up to 50 Radio Packs across all RF bands (18 Normal mode RPs and 32 High Density mode RPs)
• Easy-to-use interface with large informative backlit LCD display and quick access controls
• Simultaneously active 2-Wire and 4-Wire intercom connections
• Front panel USB ports for Radio Pack pairing, CrewCom device firmware updates, and computer connectivity
• Duplex LC Single Mode Fiber and traditional Cat 5e or greater CrewNet connections
• LAN port for CrewWare connectivity via computer network
• Front panel headset monitor station
• Stage announce audio output
• AUX In/Out for program input and intercom audio output
• GPO contact closure relays (x5)
• Sync input to receive sync from another CrewCom system
• 1U rack-mountable
• Integrated Ping function, which uses all LEDs to physically identify a target device
