For installations where the DMX cable has to run a long distance or is in an electrically noisy
environment, such as in a discotheque, it is recommended to use a DMX terminator. This helps
in preventing corruption of the digital control signal by electrical noise. The DMX terminator is
simply an XLR plug with a 120 Ω resistor connected between pins 2 and 3,which is then
plugged into the output XLR socket of the last fixture in the chain. Please see illustrations
below.
