dmx interface

DMX interfaces use both 3‑pin and 5‑pin connectors. Connector genders offered include male‑to‑male, male‑to‑female, and female‑to‑female. One terminator listing is shown as having "No Connection Gender," meaning it doesn't have a mating connector.

Most listings describe black anodized aluminum connector bodies with a plastic cap and a rubber strain‑relief boot. Many connectors use solder cups or solder posts for the conductors and a solder loop or post for the cable shield.

Converters pass pin 1 (ground) and the primary DMX data on pins 2 and 3. Any auxiliary signals on pins 4 and 5 (found on 5‑pin connectors) are not carried over when converting to 3‑pin.

Termination is provided by a 120‑ohm resistor soldered between pins 2 and 3 to properly terminate a DMX daisy chain. Product descriptions also note the terminator is housed in an anodized aluminum locking body with a plastic cap and rubber strain‑relief boot.

Yes—several listings state you can build custom DMX cables to the exact length using bulk cable. They reference use with 2‑conductor and 4‑conductor DMX lighting bulk cable.

Most entries list XLR-type connections. One product entry lists USB‑C as the connection type in its product details.

Pin 1 is ground; pins 2 and 3 carry the DMX data signal.
