DMX-512 connection/connection between fixtures
DMX/RDM
controller
Occupation of the XLR-connection:
If you are using controllers with this occupation, you can connect the DMX-output of the controller di
-
rectly 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.
Building a serial DMX-chain:
Connect the DMX-output of the first fixture in the DMX-chain with the DMX-input of the next fixture.
Always connect one output with the input of the next fixture until all fixtures are connected.
DMX-512 connection with DMX terminator:
For installations where the DMX cable has to run a long distance or is in an electrically noisy environ
-
ment, 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 resistor connected between pins 2 and 3, which is then plugged into the output XLR socket
of the last fixture in the chain.
Caution:
At the last fixture, the DMX-cable has to be terminated with a terminator. Solder a 120 Ω
resistor between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the DMX-output of the
last fixture.
