PR XR230 BEAM Manual page 8

Note: care should be taken to ensure that none of the pins touch the metallic body of the plug or each other. XLR plugs and sockets mustn't
be connected in any way other than mentioned in the above figure. The XR330BWS accepts digital control signals in protocol DMX512
(1990).
Connect the controller's DMX output to the first fixture's DMX input, and connect the first fixture's DMX output to the second fixture's
DMX input and connect the rest fixtures in the same way. Eventually connect the last fixture's DMX output to a DMX terminator as shown
in the figure below.
●DMX TERMINATOR
In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This prevents electrical
noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120Ω (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.
