What is the maximum number of fixtures to be placed on one data cable run?

Explanation:
On a DMX data link, a single run carries a total of 512 control channels. Each fixture uses a set number of channels to control its features (often 16 for a typical lighting fixture). To stay within that 512-channel limit, you can drive up to 512 ÷ 16 = 32 fixtures on one data run. This is why 32 is the practical maximum. If fixtures use more channels, the number you can run on one line drops accordingly; if they use fewer channels, you could fit more, but the common guideline remains that about 32 fixtures per DMX data run is the standard upper limit.
