6. DMX-512 control connections
Connect the provided XLR cable to the female 3-pin XLR output of your controller and
the other side to the male 3-pin XLR input of the moving head. You can chain multiple
Moving heads be connected together through serial linking. The cable needed should be
two core, screened cable with XLR input and output connectors. Please refer to the
diagram below.
DMX-512 connection with DMX terminator
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.
