DATA PORT PINOUT

The diagram below shows the pin assign- ments used for the HD-15 connectors on the DSP-3 and amplifier.

NOTE!

This information is shown for reference only and is subject to change without no- tice as the DataPort feature is specific to QSC products and not intended for inter- face to other manufacturer’s equipment.

Note: Powerlight 6.0 and Powerlight 9.0 amplifiers require that pin #9 be removed from the remote mounting interconnect cable.

Amplifier damage may result from use of cable that has pin #9 connections present.
