QSC RAVE 520az Hardware Manual page 7

Example #2 - CobraNet X-over mode:
This is the simplest connection you can make between a RAVE 520az and a "destination" product such as the BASIS 922az/902zz/904zz
or the RAVE 522aa.The RAVE 520az is the audio "source" in this example. You use a CAT-5 crossover cable connected between the
CobraNet ports of each unit. No network switch is required. This connection allows audio to pass from the RAVE 520az to the BASIS/
RAVE unit over CobraNet.
Combining example 1 and 2 lets you setup one unit at a time, much as you would have to do using a point-to-point RS232 connection,
while passing audio between them, all without a network switch. However, you would have to physically connect your computer first
to one unit and then to the other. With this elementary connection you don't have a true network. It is like making RS-232 connec-
tions - except that performance is better.
All the other examples are of proper networks and all require a network switch. On a proper network, you have direct access to all
RAVE/BASIS units all of the time without having to physically switch between them. You still get the great performance of TCP/IP
over Ethernet. (And we believe QSC's advanced networking software provides the best performance of any networked audio control
system available today, including Ethernet based systems from competitors.)
