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 QSControl (including the system controller) and a second dedicated network
for CobraNet audio. As with the previous example, as many units may be connected as there are switch ports available. All units
will be able to communicate with the computer. All will have CobraNet audio, providing at least one is an audio "source" device.
Switches can be connected to other switches to build larger networks; all of the normal networking principles apply.
