3. SETUP
Disconnect the power cord before replacing a fuse and always replace with the same type fuse.
Fuse Replacement
With a flat head screwdriver wedge the fuse holder out of its housing.
Remove the damaged fuse from its holder and replace with exactly the same type of fuse.
Insert the fuse holder back in its place and reconnect power.
The fuse is located inside this compartment. Remove using a flat head screwdriver.
Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX-512 controller or to run
synchronized shows on two or more fixtures set to a master/slave operating mode. The combined number of
channels required by all fixtures on a serial data link determines the number of fixtures that the data link can
support.
Important
: Fixtures on a serial/data link must be daisy chained in one single line. Maximum recommended serial
data link distance: 100 meters (1640 ft.) Maximum recommended number of fixtures on a serial data link: 32 fixtures
Data Cabling
To link fixtures together you must use data cables. If you choose to create your own cable, please use data-grade
cables that can carry a high quality signal and are less prone to electromagnetic interference.
CABLE CONNECTORS
Cabling must have a male XLR connector on one end and a female XLR connector on the other end.
DMX connector configuration
Termination reduces signal errors. To avoid signal transmission problems and interference, it is always advisable to
connect a DMX signal terminator.
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 check correct polarity and
to make sure the pins are not grounded or shorted to the shield or each other.
Setting up a DMX Serial Data Link
1. Connect the (male) 3 pin connector side of the DMX cable to the output (female) 3 pin connector of the controller.
2. Connect the end of the cable coming from the controller which will have a (female) 3 pin connector to the input
connector of the next fixture consisting of a (male) 3 pin connector.
3. Then, proceed to connect from the output as stated above to the input of the following fixture and so on.
Master/Slave Fixture Linking
1. Connect the (male) 3 pin connecter side of the DMX cable to the output (female) 3 pin connecter of the first
fixture.
