Dmx 512 Connection - PROEL Four Rays Rainbow User Manual

DMX-512 CONNECTION
Projector 3
Address 11
The wires must not come into contact with each other, otherwise the fixtures will not work
at all, or not will work properly.
Only use only a DMX cable and 3-pin XLR-plugs and connectors in order to connect the
controller with the fixture or one fixture with another.
Occupation of XLR-connection:
XLR mounting-socket
If you are using controllers with this occupation, you can connect the DMX-output of the
controller directly with the DMX-input of the first fixture in the DMX-chain. If you wish to
connect DMX-controllers with other XLR-outputs, you need to use adapter-cables.
CAUTION:
For all installation, having long signal cables or in the
presence of electrical noise, for example a discotheque, it
is recommended practice to use a DMX terminator: this
assist in preventing corruption of the digital control signal
by external noise. 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 DIGITAL THRU
socket on the last projector in the chain. The connections
are illustrated on the right.
