Low voltage coupling design

A multi-function controller system with pass-through power, the system comprising:

• a channel output terminal;
• a function generator module comprising circuitry to generate a pre-determined electrical waveform for being selectively output through said first channel output terminal in response to user input;
• an input DC power terminal to supply operating power to energize the at least one function generator;
• an input common terminal;
• an output DC power terminal;
• an output DC common terminal;
• a low impedance conductive path coupling the input DC power terminal to the output DC power terminal;
• and,
• a low impedance conductive path coupling the input common terminal to the output DC common terminal.

A lighting system comprising:

• a first controller for outputting one or more predetermined waveforms;
• a second controller for outputting one or more predetermined waveforms, said second controller being downstream of said first controller;
• a pass-through DC power and ground conductive path extending from and intervening said first controller and said second controller such that a DC voltage carried by said DC conductive path is adapted to be constant from a point upstream of said first controller to a point downstream of said second controller;
• a first channel wire intervening said first controller and said second controller to carry said predetermined waveforms output by said first controller, wherein said predetermined waveforms carried by said first channel wire are not carried downstream of said second controller;
• one or more lights connected to said first channel wire for being illuminated in a manner corresponding to said predetermined waveforms output by said first controller;
• and
• a second channel wire extending downstream of said second controller to carry said predetermined waveforms of said second controller, wherein said predetermined waveforms carried by said second channel wire are not carried upstream of said second controller;
• one or more lights connected to said second channel wire for being illuminated in a manner corresponding to said predetermined waveforms output by said second controller.
