DMX TERMINATOR
In the Controller mode or Master/Slave mode, the DMX output has to be connected with a DMX
terminator at the last fixture in the chain. This prevents electrical noise from disturbing and
corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120
Ω
(ohm) resistor connected across
pins 2 and 3, which is then plugged into the output socket on the last projector in the chain. The
connections are illustrated below.
Many luminaires can run synchronously by linking them with each other in the master/slave mode.
Set the address of all luminaires to 001.
Select one luminaire as the master, and set the function code 1 and 2 to “y”. Don’
t connect its
input with an XLR control cable.
Set the function code 1 and 2 of the rest luminaries to “n”. Now they are slaves.
Connect the master’
s output to the first slave’ s input with an XLR control cable, and connect the
first slave’ s output to the second slave’ s input with an XLR control cable. The rest may be
connected in the same way. Eventually connect the last slave’ s output to a DMX terminator as
shown below.
