compartment.
Remove using a flat
head screwdriver.
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.
Insert 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 fixtures
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.
DMX DATA CABLE
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
