Fuse Replacement

With a Philips screwdriver, unscrew the fuse holder out of its housing and
remove the blown fuse from its holder. Replace the blown fuse with a fuse
of the exact same type and rating, then screw the fuse holder back into
place and reconnect power.
Connecting A Bunch of Cyc Out™ Fixtures
You will need a serial data link to run light shows using a DMX-512 control-
ler 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 ap-
plications. 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

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