Multicast bundles are transmitted from one device to multiple devices on the network (one-to-many). Unicast bundles are transmitted from one device to another (one-to-one). Unicast bundles are transmitted only when another device is configured to receive them by assigning the same bundle numbers. On the other hand, multicast bundles are transmitted to all devices on the network regardless of whether any devices are configured to receive them, and only devices that are configured to receive those bundles actually process them. It is recommended that no more than four multicast bundles (offering up to 32 channels) be used, since transmis sion of multicast bundles consumes more network resources. Unicast bundles should be used if five or more bundles are required. It is also possible to set multiple devices to receive the same unicast bundle number, and depending on the transmitting device up to 4 receiving devices may be able to simultaneously receive the same bundle. This situation is known as “multi-unicast.” The DME Satellite is capable of handling multi-unicast bundles. Multicast and unicast bundles are identified by bundle number. Multicast bundles are numbered 1 through 255. Unicast bundles are numbered 256 through 65,279. Multicast bundle CobraNet Device CobraNet Device Digital Audio Data If Device A is transmitting multicast bundles, they will be transmitted to all devices on the CobraNet network (e.g., Devices B, C, and D in the example). Network A B C D CobraNet Device CobraNet Device Unicast bundle CobraNet Device CobraNet Device Digital Audio Data If Device A is transmitting unicast bundles, and the same bundle numbers are assigned to the transmitting bundles on Device A and receiving bundles on Device D, then Device A will transmit the unicast bundels to Device D. Network A B C D CobraNet Device CobraNet Device DME8i-C/DME8o-C/DME4io-C Owner’s Manual Conductors and performers Foreword One device on the CobraNet network works as the conductor (network sync master). All other CobraNet devices are performers (network sync slaves). Each device synchronizes its own internal clock to the beat packets (sync signals) transmitted by the conductor. The conductor device is chosen automatically and no user intervention is required. However, setting an appropriate conductor priority could enable users to assign any device as the conductor. Refer to the DME Designer Owner’s Manual for more information on setting the conductor priority. If the DME Satellite is the conductor, the [IN USE/CONDUCTOR] LED flashes orange. If the conductor fails, another device automatically takes over. Since the conductor transmits beat packets (sync signals) onto the network, each performer does not require an external word clock connection, reducing cabling complexity and cost. Any non-networked digital audio equipment should derive its word clock from a CobraNet networked device. NOTE All CobraNet networked devices, regardless of whether each device ser ves as the conductor or a performer, can receive digital audio data and control data. Cables and hubs for CobraNet network Category-5 metal cables can be used for runs of up to 100 meters. The maximum distance for multimode fiber optic cable is 2 kilometers. However, due to differences in cables, as well as switching hub and CobraNet device performance, proper operation at the maximum length cannot be guaranteed in all cases. Always use switching hubs in a CobraNet network. When using metal cable for connections, be sure to use Category 5 straight cables.
