QSC Audio Amplifier Network Monitor CM16a - Manual (Page 15)

Section 1:
Introduction- Sample Network Topologies
The simplest network configuration is a single
system controller computer and a CM16a con-
nected by a single Ethernet crossover cable. A
standard Ethernet cable would NOT work. The
crossover-type cable must be used when con-
necting the CM16a directly to the system con-
troller computer. This type of cable switches
(or crosses over) the transmit and receive sig-
nals from one end to the other enabling con-
nection without any intermediate devices. See
page 37 for crossover cable pinouts.
For CAT-3 or CAT-5 distances longer than 100
meters (~300 feet) a repeater must be used. An
active hub or Ethernet switch may be used as
well. Active hubs “clean up” and retransmit the
network traffic, much as a repeater does, only
with multiple ports. The active hub or switch
would allow for future expansion.
If there are two or more CM16a’s in
the network (or other network de-
vices present) use a hub or switch
to create a star topology.
