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

Fuse Replacement
CAUTION! The STROBE-1000-LED-RGB+W utilizes a high-output switch-mode power supply with an
internal fuse. Under normal operating conditions, the fuse should not require replacement. The fuse is field
replaceable,however it is an advanced procedure suited to qualified individuals. Should your STROBE-1000-
LED-RGB+W fuse require replacement, please contact your dealer for instructions.
Connecting A Bunch of STROBE-1000-LED-RGB+W Fixtures
Follow the guide below to properly link fixtures. Power the first fixture in the chain with a standard cable (pro-
vided with fixture). Then jump each subsequent fixture with a properly rated jumper cable. WARNING: DO
NOT POWER LINK MORE THAN (2) FIXTURES IN ONE SINGLE CHAIN, ELECTRICALOVERLOAD MAY
OCCUR.
Data/DMX Cabling
To link fixtures together you’ll need data cables.You should use data grade cables that can carry a high qua-
lity signal and are less prone to electromagnetic interference. 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
To build your own
DMX Terminator:
Obtain a 120-ohm, 1/4-watt resistor,
and wire it between pins 2 & 3 of
the last fixture. They are also readi-
ly available from specialty retailers
Cable Connectors
Cables must have a male XLR
connector on one end and a female
XLR connector on the other end.
A Word on Termination
DMX is a resilient communication pro-
tocol, however errors still occasiona-
lly occur. Termination reduces signal
errors, and therefore best practices
include use of terminator in all circum-
stances. If you experiencing problems
with erratic fixture behavior, especia-
lly over long cable runs, a terminator
may help improve performance.
CAUTION: Do not allow contact between the common and the fixture’s chassis ground. Grounding the com-
mon 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.
