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 exact same type fuse.
Connecting A Bunch of LB™ Bar CSI
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 mas-
ter/slave operating mode. The combined number of channels required
by all the fixtures on a serial data link determines the number of fix-
tures 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 dis-
tance is 500 meters (1640 ft). The maximum recommended number of
fixtures on a serial data link is 32 fixtures.
Data/DMX Cabling
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
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.
