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 30 devices should be connected on one data link.
Connecting more than 30 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 DMX data link distance: 100 meters
Maximum recommended number of Galactics on a DMX data link: 30 fixtures
Data Cabling
To link fixtures together you must obtain data cables. You can purchase DAP Audio 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.
