Which statement is most accurate regarding DMX data cabling?

• A. XLR connectors, including 3-pin and 5-pin variants, are used for DMX data.
• B. RJ45 connectors are the standard for DMX data.
• C. HDMI carries DMX data.
• D. USB is used for DMX data.

Answer: (A)

DMX data cabling relies on XLR connectors, with the standard for DMX512 being a 5-pin XLR. The signal is carried on pins 2 and 3 (data− and data+), while pin 1 is ground and pins 4 and 5 are typically unused or reserved. Some older or specific gear uses a 3-pin XLR for DMX, which is why you may encounter 3-pin variants, but 5-pin XLR is the common standard. RJ45, HDMI, and USB are not the native DMX data cabling; they’re used in other technologies or in DMX-over-IP setups, which involve different protocols and infrastructure.
