Page 8 - How It Works
8 Ethernet networks are used most often for data communica- tions, such as with file or print sharing on an office LAN (Lo- cal Area Network). A typical application might include a num- ber of PCs or workstations, servers and shared printers all connected to common Ethernet hardware. Messages (Ether...
Page 10 - Channel Routing
10 Channel Routing A RAVE network handles routing in bundles of up to eight audio channels. Each bundle of audio transmitted on the network oc- cupies a unique identifier, or number. In stand-alone mode, each RAVE device handles two bundles—two sent, two received, or one of each. For example, a RAVE...

18 The RAVE “s” series AES/EBU input models provide some additional means for synchronizing the CobraNet network and deriving on-board clocks. In addition to the on-board PLL and external synch inputs available on all models, the AES/EBU input models allow the user to synchronize the network to a 48...

24 A RAVE network routes audio signals in bundles of up to 8 channels. Behind the removable cover on the front panel are two pair of hexadecimal switches for assigning bundles to the 8-channel audio groups. Note that the following discussion only applies to front panel configuration of RAVE devices ...

25 Switches set to “10” through “FE” hex assign unicast bundles. Switches set to “01” through “0F” hex assign multicast bundles. Switch settings “00” and “FF” hex are reserved for special functions. “FF” hex puts the unit into utility mode for programming and also forces software kill. “00” hex disa...
