Remember, we're talking about huge networks here - the network in question had 12 switches wired in series. We try and make it easy for CobraNet licensees to use SNMP in their products. I am also aware that getting everyone on board with a control protocol can be a dicey thing. Any reasonably sophisticated network gear is expected to have an SNMP implementation. SNMP simply allows you remotely to get and set values of variables.
Variables can be preamp gain, internal temperature, audio channel assignments.
A bundle originates at a transmitter and can be received by one or more receiving devices. A bundle can carry up to 8 audio channels. To establish an audio route, select an unused bundle at the source and select the same bundle number at the destination. We continue to enhance CobraNet but we're doing it in a completely backwards compatible way. Peavey has their protocol for speaking to their boxes.
