Cable Connectors
Cabling must have a male XLR connector on one end and a female XLR connector on the other end.
Do not allow contact between the common and the fixture’s chassis ground. Grounding the
common 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.
Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX 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.
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.
Maximum recommended serial data link distance: 500 m (1640 ft)
Maximum recommended number of fixtures on a serial data link: 32

To avoid signal transmission problems
and interference, it is always advisable to
connect a DMX signal terminator.
