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 OHM resistor connected between pins 2 and 3,which is then 
plugged into the output XLR socket of the last fixture in the chain.
