3. SETUP

Fuse Replacement

Disconnect the power and remove the unit's power cord. Once the cord has been removed
locate the fuse holder that is located next to the power input/output connections. Using a
phillips head screwdriver, unscrew the fuse holder. Remove the bad fuse and replace with a
new one, then screw the fuse holder back into place.
Connecting A Bunch of Flurry™ Z Fixtures
You will need a serial data link to run light shows using a DMX-512 controller or to run
shows on two or more fixtures set to sync in master/slave operating mode. The combined
number of channels required by all the fixtures on a serial data link determines the number
of fixtures the data link can support.
Fixtures on a serial data link must be daisy chained in one single line. Also, connecting
more than 32 fixtures on one serial data link without the use of a DMX optically-isolated
splitter may result in deterioration of the digital DMX signal.
The maximum recommended cable-run distance is 500 meters (1640 ft). The maximum
recommended number of fixtures on a serial data link is 32 fixtures.
Data/DMX Cabling
To link fixtures together you'll need data cables.
You should use data-grade cables that can carry a high quality signal and are less prone to
electromagnetic interference.
For instance, Belden© 9841 meets the specifications for EIA RS-485 applications.
Standard microphone cables will "probably" be OK, but note that they cannot transmit
DMX data as reliably over long distances. In any event, the cable should have the following
characteristics:
• 2-conductor twisted pair plus a shield
• Maximum capacitance between conductors – 30 pF/ft.
• Maximum capacitance between conductor & shield – 55 pF/ft.
• Maximum resistance of 20 ohms / 1000 ft.
• Nominal impedance 100 – 140 ohms
For longer cable runs, it is a good idea to have a DMX terminator plug inserted into the
female XLR (DMX output) connector of the last unit. This will properly terminate the data
signal, greatly decreasing the possibility of erratic behavior.

Before replacing the fuse, disconnect the power cord.
ALWAYS replace it with the same type and rating.
