There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A fixture capable
of receiving DMX-512 will require one or a number of sequential channels. The user must assign a starting
address on the fixture that indicates the first channel reserved in the lighting console. There are many different
types of DMX controllable fixtures and they all may vary in the total number of channels required. Choosing a
start address should be planned in advance. Channels should never overlap. If they do, this will result in erratic
operation of the overlapping fixtures. You can however, control multiple fixtures of the same type using the same
starting address as long as the intended result is that of unison movement or operation. In other words, the
fixtures will be slaved together and all will respond identically.
DMX fixtures are often designed to receive and transmit data through a DMX daisy-chain. A DMX daisy-chain is
where the DMX OUT of one fixture connects to the DMX IN of the next fixture. The order in which the fixtures
are connected is not important and has no effect on how a lighting console communicates to each fixture. Use
an order that provides for the easiest and most direct cabling. Connect fixtures using shielded two conductor
twisted pair cable such as ProPlex
®
DMX with 5-pin XLR male to female connectors. The shield/ground is pin 1,
while pin 2 is Data Negative (D-) and pin 3 is Data positive (D+). Pins 4 and 5 are not used according to the
DMX-512 standard.

To maintain optimum performance and minimize wear fixtures should be cleaned frequently. Usage and
environment are contributing factors in determining frequency. As a general rule, fixtures should be cleaned at
least twice a month. Dust build up reduces light output performance and can cause overheating. This can lead
to reduced lamp life and increased mechanical wear. Be sure to disconnect power to the fixture before
conducting maintenance.
Unplug fixture from power. Use a vacuum or air compressor and a soft brush to remove any dust
on external vents and internal components. Clean all glass when the fixture is cold with a mild solution of glass
cleaner or Isopropyl Alcohol and a soft lint free cotton cloth or lens tissue. Apply solution to the cloth or tissue
and drag dirt and grime to the outside of the lens. Gently polish optical surfaces until they are free of haze and
lint.
