I n t r o d u c t i o n HUB MANUAL Decentralized Network Architecture The CrewCom system utilizes a proprietary network backbone, known as CrewNet , to coordinate and transport all system timing, ™ audio, signaling, and controls. This efficient, decentralized resource network delivers increased flexibility over that of traditional technologies, using a distributed network-to-device intelligence within a modular building block structure.
PoC to connected CrewNet-compatible devices. To ensure best performance, especially with larger CrewCom configurations and longer cable lengths, Pliant recommends utilizing the supplied 48VDC power supply to locally power each Hub. However, powering a Hub and the devices connected to it via PoC may be advantageous in some smaller configurations.
P r o d u c t O v e r v i e w HUB MANUAL Product Overview The CrewCom Hub operates on CrewNet and allows a variety of CrewCom devices to be interconnected. The Hub consists of CrewNet ports that enable users to add more CrewCom devices, such as Radio Transceivers, in order to extend the connection of their CrewCom system.
