CobraNet Bundles?

The user is free to assign CobraNet bundles as they desire. There are a few general rules however, that must be heeded. First, only a single transmitter device should be assigned to any bundle. If more than one transmitter is assigned to a bundle, only the first transmitter assigned that bundle will be allowed to transmit. Also, be aware that CobraNet bundles do not need to be assigned sequentially.

Broadcast bundles are a global resource there may be only one transmitter assigned to a broadcast bundle during any isochronous cycle. This restriction is enforced by the conductor. Broadcast bundles represent a least common denominator for audio interoperability in networks configured via front panel selections. Since these bundles are always broadcast, no reverse reservation is required to receive them. Since they are never unicast, Broadcast bundles can wreak havoc on switched networks.

Public bundles are a global resource there may be only one transmitter assigned to a public bundle during any isochronous cycle. This restriction is enforced by the conductor. These bundles may be unicast or broadcast at the discretion of the transmitter based on reception of reverse reservation requests.
