    7 Repeater — Network repeaters are commonly referred to as Ethernet multi-port hubs. A data signal arriving in any port is reproduced out all other ports on the hub. A repeater hub does not buffer or interpret the data passing through it. An Ethernet network is typically wired in a star configuration and the repeater hub is at the center . Repeat ...

    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 - net frames) are communicated between devices on ...

    9 In default mode, the signals from the first 8 audio channel in- puts will be grouped together in a bundle whose “ network iden- tifier ” number is specified from the front-panel hexadecimal switches or through the management interface. The bundle will then be sent over the network to the destination devices that are configured, or set to rece ...

    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 RA VE device handles two bundles — two sent, two received, or one of each. For example, a RA VE 161, with 16 analog audio inputs, support ...

    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 kHz AES/EBU input stream. The 48 kHz stream ...

    21 Tx This LED illuminates green for at least 50 milliseconds while the unit is transmitting Ethernet data. This indicator will blink when transmit activity is present. The activity of this indicator is dependent on the RA VE model and bundle type. This is a physical layer indicator and does not guarantee that data is being transmitted properly fro ...

    27 When a switch is shared with non-CobraNet data, it should be configured so that CobraNet audio is isolated from conventional data communications. Partitioning is usually accomplished by enabling multiple VLANs. Co- braNet data should be given the highest network prior - ity in order to prevent the loss of audio.
