Well at last I figured out the adressing bit. most suggestions made here was correct and I thank you guys.

Another problem has cropped up.

Recently we purchased several very simple LED light fixtures. When I connected them to our existing lighting system (replacing damaged ones with these). They do not work like the original ones did.

A brief description of the light fixture is necessary.

Old Fixture: LED Uplights, 3 colours (RGB). The Power supply and DMX card is integrated into one box and is daisy chained to similar boxes upto 32 numbers. They work very well.

NEW Fixture : LED uplights, 3 colours (RGB). The power supply is a seperate box, the light fixture has the DMX card built in. Works but has a problem.

The fixture works but when 2 colours are on (one fading in and the other fading out) the third colour also comes on and begins to flicker (the third colour LED shuld not be on at all).

If one of the 2 colors that fades in and fades out is RED this again happens with the red till it achieves maximum brightness. By the time of Maximum brightness it is the only colour as the first colour has fadded out.

What is the problem and how can this be solved.
