The LED300 features our DownShifter technology that shifts incoming DMX512 data and outputs the desired channels as channels 1, 2 and 3. This allows all fixtures to be set to address "001" with the power supply routing the proper signals to the proper outputs. To enable DownShifter mode the address switch is set to a valid DMX512 address (1 through 512). The system then operates similar to a dimmer pack with the first fixture being controlled by the selected channel (and the two successive channels), the second fixture being controlled by the selected channel plus three, the third fixture being controlled by the selected channel plus six, and so forth.

DownShifter mode is disabled (so DMX512 data passes through to every output unmodified) by setting the address switch to 000.

The LED300 can provide 5 volt differential or single ended 24 volt data. The majority of DMX512 controlled accessories that operate on 24 volt power use 5 volt differential data. Original Color Kinetics ColorBlast and iColor Cove products also used 5 volt differential data. Newer Color Kinetics ColorBlast 6 and ColorBlast 12 require 24 volt single ended data (3-wire protocol). Control data is placed on pins 2 and 3. Differential data uses pin 2 for data- and pin 3 for data+. Single ended data places the same signal on both pin 2 and pin 3 so either pin can be used for control.

The LED300 is convection cooled (no fan) for silent operation. The supply is provided with a North American Parallel Blade with Ground (PBG) mains connection. It is internally switchable to nominal 115 volt or 230 volt operation.
