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:
Maximum recommended serial data link distance: 500 m (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.

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:
Type:
Maximum capacitance between conductors:
Maximum capacitance between conductor and shield:
Maximum resistance:
Nominal impedance:
Hurricane™ Haze User Manual
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 fixtures 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.
