Example #4 - Two-Wire Interface (shared network hardware):
This example illustrates the Two-Wire Interface with a managed Ethernet switch. The switch is configured with multiple virtual local area networks (VLANs). Ethernet deliveries can only reach destination ports belonging to the same VLAN from which it was sourced. The figure shows a separate VLAN for QSControl.net traffic and a separate VLAN for CobraNet audio traffic. This config- uration essentially provides a dedicated network for BASIS 922dz control and monitoring (including the system controller) and a second dedicated network for CobraNet audio. As with the previous example, as many BASIS 922dz units may be connected as there are switch ports available. All BASIS units will be able to communicate with the computer. All will have CobraNet audio. Switches can be connected to other switches to build larger networks; all of the normal networking principles apply.
