Fuse Replacement
With a Phillips #2 screwdriver, unscrew the fuse holder from its housing. Remove the damaged fuse
from its holder and replace with exact same type fuse. Screw the fuse holder back in its place and
reconnect power.
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 the fixtures on a serial data link determines the number
of fixtures the data link can support.
Important: Fixtures on a serial data link must be daisy chained in one single line. To comply with
the EIA-485 standard no more than 32 devices should be connected on one data
link. 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.
Maximum recommended serial data link distance: 500 meters (1640 ft.)
Maximum recommended number of fixtures on a serial data link: 32
Data Cabling
To link fixtures together you must obtain data cables. You can purchase CHAUVET® certified DMX
cables directly from a dealer/distributor or construct your own cable. 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.

Use a Belden© 9841 or equivalent cable which meets the specifications for EIA RS-485 applications.
Standard microphone cables cannot transmit DMX data reliably over long distances. The cable will
have the following characteristics:
2-conductor twisted pair plus a shield
Maximum capacitance between conductors
– 30 pF/ft.
Maximum capacitance between conductor and shield
– 55 pF/ft.
Maximum resistance of 20 ohms / 1000 ft.
Nominal impedance 100
– 140 ohms
Disconnect the power cord before replacing a fuse, and always
replace with the same type fuse.
