Audio Network Connector
The Audio Network connector should be wired using shielded CAT5, 5e, 6 or 7 cable cabling to interface
to a Vocia system via a Ethernet network switch. This connection carries control data, power and digital
audio over CobraNet.
PoE-enabled network switches or PoE midspan adapters must be used to power the unit. These must be
802.3at Type 1 (class 2) compliant. The maximum cable distance between any unit and an Ethernet
switch is 328 feet (100 meters) when using copper cabling. Additional Ethernet switches and/or fiber-optic
cable can be used to further extend distances between units on a network. Please note that CobraNet
limits network extensions to seven hops (one-way transmissions) within a 100Mb network. If other
network traffic shares an Ethernet switch with the Vocia network, a managed switch should be used with
separate VLANs.
The connector provides two LEDs that indicate Ethernet link and network activity (see table below).
