Which statement about 120V AC supply cables in DMX setups is true?

• A. They should be daisy-chained
• B. They should not be daisy-chained
• C. They can be used as data cables
• D. They must be color-coded blue for DMX

Answer: (B)

Power and data stay separate in DMX setups. 120V AC supply cables carry mains power, and you should distribute that power in parallel through a proper power distribution system rather than chaining one device’s outlet to the next. Daisy-chaining power feeds can overload the circuit, cause voltage drop along the chain, and make fault isolation and safety compliance harder. DMX data, on the other hand, runs on dedicated low-voltage data cables, not on mains power cables. Color-coding of mains cables isn’t standardized for DMX, so there isn’t a universal requirement to color them blue. So the true statement is that you should not daisy-chain 120V AC supply cables in DMX setups.
