is avail-
able in a 120v and 220v version. Because line voltage may vary from
venue to venue, you should be sure your unit voltages matches the
wall outlet voltage before attempting to operate you fixture.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used as a form of communication between intelligent fixtures
and controllers.
A DMX controller sends DMX data instructions from
the controller to the fixture. DMX data is sent as serial data that trav-
els from fixture to fixture via the DATA “IN” and DATA “OUT” XLR ter-
minals located on all DMX fixtures (most controllers only have a DATA
“OUT” terminal).
DMX Linking:
DMX is a language allowing all makes and models of
different manufactures to be linked together and operate from a sin-
gle controller, as long as all fixtures and the controller are DMX com-
pliant.
To ensure proper DMX data transmission, when using several
DMX fixtures try to use the shortest cable path possible. The order
in which fixtures are connected in a DMX line does not influence the
DMX addressing. For example; a fixture assigned a DMX address of 1
may be placed anywhere in a DMX line, at the beginning, at the end,
or anywhere in the middle. When a fixture is assigned a DMX address
of 1, the DMX controller knows to send DATA assigned to address 1
to that unit, no matter where it is located in the DMX chain.
Dipswitches in DMX mode:
This unit uses dipswitches to assign a
DMX address. Each dipswitch represents a binary value.
Dipswitch 1 address equals 1
Dipswitch 2 address equals 2
Dipswitch 3 address equals 4
Dipswitch 4 address equals 8
Dipswitch 5 address equals 16
Dipswitch 6 address equals 32
Dipswitch 7 address equals 64
Dipswitch 8 address equals 128
Dipswitch 9 address equals 254
Dipswitch 10 - Some units omit dipswitch 10. When a unit does
include dipswitch #10, it is usually used for special functions such as
