ENGLISH ■ Conductor and Performers On any CobraNet network one device generates a timing signal that all other devices receive and are synchronized to. The device that generates the synchronization signal is known as the "conductor," while all other devices are "performers." The conductor for the network is automatically assigned and need not be specified by the operator. When an MY16-C is assigned to be the conductor for the network, the LED indicator to the right of the connector that is connected to the network will light orange. If the conductor fails for some reason, conductor status is automatically switched to another device on the network. Since the conductor transmits the synchronization signal to the performers via the network cable, no separate word clock cables are required and the total number of cables used by the system is kept to a minimum. Digital audio devices that are not connected to the network, however, will need to receive a word clock signal from a device on the network in order to achieve synchronization. n Digital signals and control data are transmitted and received by all conductor and performer devices on the CobraNet network. Performer (Receive) C Performer (Receive) D Sync (Word Clock) Network Conductors transmit the synchronization signal that is received and used by performers. Clock synchronization is necessary to transfer digital audio data to and from devices outside the CobraNet network. In this example device B on the CobraNet network sends the synchronization signal to external device E.

"Cross" and "straight" Ethernet cables are available. "Cross" cables should be used for direct connection between two devices. Hubs and "straight" cables are required to connect 3 or more devices. Ethernet hubs are available in "repeater" and "switching" configurations. Switching hubs are recommended for use on CobraNet networks. The use of repeater hubs can result in excessive network traffic, thus reducing network efficiency. It is best to use a repeater hub that has been tested and certified by Peak Audio.
