DMX CONTROL CONNECTION:
Connection between controller and projector and between one projector and another must be made with a twin-screened cable, with
each wire having at least a 0.5mm in diameter. Connection to and from the projector is via cannon 5 pin (which are included with the
projector) or 5 pin XLR plugs and sockets. The XLR's are connected as shown in the figure above.
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.
