CREWNET Ports 1–8 and Status LEDs:
The CrewNet ports allow the Hub to connect to the CrewCom Control
Unit and Radio Transceivers, supporting a proprietary network design where all devices are part of a CrewCom
Configuration File that shares data, timing synchronization, and audio. Ports 2 through 8 are duplex LC Single
Mode Fiber ports; Port 1 can be either the first fiber port or the copper (RJ-45, Cat 5e or greater) port, and only
one may be used at a time. See
for more LED information.
Note
: Port 1 (copper only) is only capable of PoC input, and Port 1 cannot supply PoC output.
Either copper or fiber use of Port 1 is required for downstream operation of ports 2–8.
Fiber Hub Power Tips:
Port 1 (copper only) cannot power devices. It can only accept power,
and this power is indicated with the NET PWR LED. Either copper or fiber use of Port 1 is
required for downstream operation of ports 2–8. Since Ports 1–8 cannot source power to
downstream devices, even if the Hub is locally powered, any device connected to a Fiber Hub
will require its own local power supply. 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.
Each port’s status LEDs indicate the status of the CrewNet connection. See
for more
LED information.
