CAUTION:
Do not allow contact between the common and the fixture’s chassis
ground. Grounding the common can cause a ground loop, and your fixture may
perform erratically. Test cables with an ohm meter to verify correct polarity and
to make sure the pins are not grounded or shorted to the shield or each other.
Take It To The Next Level: Setting Up DMX Control
Step 1:
Connect the male connector of the DMX cable to the female connector
(output) on the controller.
Step 2:
Connect the female connector of
the DMX cable to the first fixture’s male
connector (input).
Note:
It doesn’t
matter which fixture address is the
first one connected. We recommend
connecting the fixtures in terms of their
proximity to the controller, rather than
connecting the lowest fixture number
first, and so on.
Step 3:
Connect other fixtures in the
chain from output to input as above.
Place a DMX terminator on the output
of the final fixture to ensure best
communication.
Fixture Linking (Master/Slave Mode)
1. Connect the male 3/5-pin connector side of the DMX cable to the output
(female) 3/5-pin connector of the first fixture.
2. Connect the end of the cable coming from the first fixture which will have a
(female) 3/5-pin connector to the input connector of the next fixture consist
-
ing of a (male) 3/5-pin connector. Then, proceed to connect from the output as
stated above to the input of the following fixture and so on.
Mounting & Rigging
•
This unit may be used on the floor, or mounted in any SAFE position provided
there is enough room for ventilation.
•
Mount the fixture using a suitable “C” or “O” type clamp. The clamp should
be rated to hold at least 10x the unit’s weight to ensure structural stability. Do
not mount to surfaces with unknown strength, and ensure properly “rated” rig-
ging is used when mounting fixtures overhead.
•
Adjust the angle by loosening both knobs and tilting the unit. After finding
the desired position, retighten both knobs.
• Safety cables MUST ALWAYS be used.
• Never mount in places where the unit will be exposed to rain, high humidity,
extreme temperature changes or restricted ventilation.
