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.

controller. The allocation of this starting address is achieved by setting the correct number on the
