    See Section 3.2.1. The dual RJ45 CobraNet connectors allow a Primary & Secondary connection to the 100 Mbps Ethernet network. Should the Primary connection lose link activity with the net work, the module will automatically switch to the Secondary connection to ensure uninterrupted audio and control.

    In System Architect, you create audio connections between sending devices (transmitters) and receiving devices (receivers). For example, a mixer could be a transmitter, and a power amp could be a receiver. You assign each connection a Bundle number. The Bundle number indicates which devices are communicating with each other.
