A. AC Power Connection: 100–240V, 50/60 Hz 0.8A (complies with standard IEC60320; IEC320/C13)
B. RELAY Connection: CrewCom includes five General Purpose Output (GPO) contact closures for interfacing
with other external devices (the Stage Announce (SA) Relay and four additional GPO relays). The user has
access to both the normally open and the normally closed contacts for each relay. Rated load for all relay

C. CREWNET Ports (RJ-45 or Fiber): The CrewNet ports allow the Control Unit (CU) to connect to other
CrewCom devices, supporting a proprietary network design where all devices are part of a CrewCom
Configuration File that shares data, timing synchronization, and audio. Up to two CrewNet connections are
supported per CU using either two RJ-45 copper (Cat 5e or greater) ports or an RJ-45 copper and Single Mode
Fiber (duplex LC connector) port. Any CrewCom device connected to CrewNet via a Cat 5e (or greater) cable
will receive Power-over-CrewNet (PoC) from the CU via the CrewNet port. (See
page 15.) Each CrewNet port's status LEDs indicate the status of the CrewNet link. (See
page 45.)
