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 Series
may damage an ISA amplifier or an original PowerLight amplifier.

Packing List
QSC part # FG-000951-00
• DDI-11 board
• Two #4-40 × ¼" black screws
• Installation guide
Procedure
1. Turn off the amplifier, Basis, or Q-Sys device.
2. Plug the card into the DataPort. Use the two screws on each side of the DataPort to secure it; do not overtighten them.
3. To attach wires to the DDI-11 terminal strip, strip about 5 mm (0.2") of insulation from the wire. Twist the exposed wire strands together and make
sure there are no stray ones. Turn the screw on the terminal counterclockwise until you can fully insert the wire end into the terminal. Turn the
screw clockwise until the terminal clamps the wire securely. Repeat for all the wires needed. The terminal can accept stranded wire up to 17 AWG
(1 mm
