Networked Paging Station-1 - Rear Panel Connectors
dc power: This 2mm barrel connector is for an optional user-provided external power supply (12~24VDC 3W). In most circumstances,
this connection is not used, and power is instead provided at the Power + Data connection (see below). An external power supply may be
necessary if CobraNet
® network switches do not provide Power-Over-Ethernet (PoE) and PoE adapters are not available, or if it is
desirable to perform certain Networked Paging Station-1 setup functions without an available CobraNet network connection (PoE).
power + data: This RJ45 connector utilizes CAT5 cabling to interface the Networked Paging Station-1 to an AudiaFLEX system. This
connection is made to the primary CobraNet port of an AudiaFLEX unit, either directly (single station) or via network switches (multiple
stations). This connection carries digital audio and control data over CobraNet. The CobraNet port of an AudiaFLEX does not provide
Power-Over-Ethernet (PoE). Therefore, PoE enabled network switches, PoE adapters, or external power supplies must be used. The
Power + Data connector provides two LEDs, indicating link/activity and Power-Over-Ethernet (PoE).
