ENGLISH ■ Multicast Bundles and Unicast Bundles Two types of bundle can be used with CobraNet: "multicast" bundles and "unicast" bundles. Multicast bundles can be transmitted from a single device to all devices on the network, while unicast bundles are transferred from a single transmitting device to a single receiving device or a limited number of receiving devices. Unicast bundles are only sent to devices which have been set to the same bundle number as the transmitting device. Multicast bundles are sent to all devices on the network regardless of their settings, but only bundles with the specified bundle number(s) are processed. For this reason multicast bundles make heavy use of network resources and it is recommended that the maximum number of bundles be limited to 4 (32 channels). Unicast bundles should be employed when it is necessary to handle 5 or more bundles at a time. Different number ranges are used for multicast and unicast bundles: multicast bundles are numbered 1 through 255, while unicast bundles are numbered 256 through 65,279. Multicast Bundles Multicast bundles transmitted from device A are sent to all devices on the network (B through D in the example).
