This DMX Terminator is a XLR male connector with a 120 ohm resistor soldered across pins 2 and 3 to provide the proper termination in a chain of DMX devices.

Add the terminator as the last item in a DMX chain to prevent a signal reflection that adds noise and degrades DMX performance.

XLR3M Why use a terminator? Incorrect or missing termination is probably the single most common cause for faulty DMX systems. DMX signals are high-speed electrical waveforms with signal energy in the radio frequency (RF) range. When an RF signal travels down the DMX cable (at near the speed of light) and gets to the end of an un-terminated cable, a percentage of the signal is "reflected" back up the cable and mixes with later waveforms coming down the cable, creating noise and interference. This can be avoided by absorbing the maximum amount of energy using a terminator which matches the characteristic impedance (120 ohms) of the cable.
