Introduction The DDI-11 DataPort Accessory Card is designed for use with QSC amplifiers equipped with a DataPort connector. It provides an easy way to exploit the features of the DataPort without using QSControl or an accessory. In addition, the DDI-11 can be used on a DataPort outputs of a Basis or Q-Sys I/O card to provide access to the audio signals. Refer to Outputs below. VM1 300mA +15V Refer to Figure 1 and Figure 2.
Power Supply The +15 volt output is referenced to the chassis ground terminal and will provide up to 300 mA from the amplifier to power custom accessories or other devices. The output is protected from short circuits or excessive current draw by a self-resetting polyswitch fuse. The +15 volt terminal on ISA and original PowerLight Series1 amplifiers, however, cannot provide enough current to power external circuitry. Doing so may damage an ISA amplifier or an original PowerLight amplifier.
