32.6CobraNet

CobraNet is a standard for transporting multiple digital uncompressed audio channels over Ethernet. Many manufactures of public address and professional audio equipment support this standard. CobraNet has all the advantages of Ethernet: structured cabling using Cat-5 and GOF to cover long distances and cheap network components. In Praesideo systems, the LBB4404/00 CobraNet Interface is used to interface between Praesideo and CobraNet. These CobraNet interfaces can be used to:

•Connect Praesideo systems (see figure 32.4 for an example).

•Benefit from already existing Ethernet infrastructure.

•Transport audio over large distances.

PC data such as Praesideo Open Interface data can coexist with CobraNet on the same Ethernet network as long as managed Ethernet switches are used. See: http://www.cobranet.info/en/support/cobranet/design/

Because of delay variations, it is not allowed to connect more than 7 switches in series.

Fast Ethernet distance limitations apply to CobraNet installations: 100 meters over Cat-5 copper cable, 2 kilometers over multimode fiber. Proprietary Fast Ethernet via single mode fiber solutions can reach even further.

Note

The CobraNet interface does not transfer control functions. These can only be transferred over Ethernet using the Praesideo Open Interface. Network controllers are always open interface slaves, which must be controlled by an open interface master, for example a PC Call Station.
