INSTALLATION-
DATAPORT CONNECTION
The QSC DataPort connection carries input signals, amplifier output monitoring signals, remote amplifier
power on/standby control, amplifier temperature, and more, all on one cable. Each DataPort is clearly
marked indicating which channel's amplifier it should be connected to. Follow the back panel labeling.
Connect each DataPort to its respective amplifier's DataPort. Finger-tighten the retaining screws on the
cable connectors; do not overtighten!
Connect a DataPort cable from each of the DCM's DataPorts to each of the system's DCA amplifiers.
Orient the cable's HD15 male connector
properly and push the connector onto the
DCA's receptacle. Finger-tighten the
retaining screws to ensure reliable
connection. Connect the other end of the
cable to the DataPort on the correspond-
ing channel's DCA amplifier.
