Securing with a safety cable
Secure the fixture with a safety cable (or other secondary attachment) that is approved for the weight of
the fixture so that the safety cable will hold the fixture if a primary attachment fails.
Loop the safety cable through the eyebolt in the back of the fixture and around a secure anchoring point.
Do not loop the safety cable around the fixture’s mounting bracket only, as this will leave the fixture un
-
secured if it separates from the bracket.
DMX-512 connection/connection between fixtures

controller
Occupation of the XLR-connection:
1. Group
2. Signal (-)
3. Signal (+)
DMX OUT
1. Group
2. Signal (-)
3. Signal (+)
DMX IN
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.
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 re
-
sistor between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the DMX-output of the last
fixture.
