QSC BASIS 914lz Hardware Manual

8
Example #3 - Single Wire Interface:
Here all QSControl.net and CobraNet traffic shares the same single CAT-5 cable between the BASIS 914lz and an unmanaged Ethernet
switch. The QSControl.net system manages traffic flow efficiently and reliably so that all audio and control data is delivered to its
appropriate destination anywhere on the network. Though the example shows only two BASIS 914lz units, as many devices may be
connected as there are available switch ports. All BASIS units will be able to communicate simultaneously 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. (Note: there must be at least two CobraNet devices online for any data - audio or control - to come out of the CobraNet port.)
