standard unshielded twisted-pair (UTP)
network cable. Both ends of the cable
are wired identically.
RJ-45 Pinout for an Ethernet
Crossover Cable
A crossover cable has the RX and
TX wire pairs switched around at
one end. There are only two likely
situations that would require a
crossover cable: to connect a sin-
gle system controller computer
directly to a single CM16a device;
and to cascade hubs that don’t
have uplink ports.
DataPort Pinout
The diagram to the right shows the pin assignments
used for the HD-15 connectors on the CM16a and
amplifier.
NOTE! This information is shown for reference only
and is subject to change without notice as the
DataPort feature is specific to QSC products and not
intended for interface to other manufacturer’s equip-
ment.
