CobraNet TM Routing Primer
Steve Gray, Cirrus Logic, Inc.
Configuring CobraNet TM systems to properly route audio is fairly straightforward once the underlying
concepts are understood. This document explains the concepts behind end to end routing and how to
configure CobraNet
TM interfaces to route audio channels. Use this document as a companion to the available
CobraNet TM device Data Sheets and Reference Manuals.
The variables referred to in this document are described in the CobraNet
TM Programmer’s Reference. They
are known as Management Interface (MI) variables and can be read and written via the hardware Host
Management Interface (HMI) or via SNMP over the network.
The signals referred to are described in the Datasheet or Hardware Reference Manual applicable to the
particular CobraNet
TM interface in use.
Referring to Figure 1 below, let’s consider the components of CobraNet TM audio routing.
