DMX Linking: 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.

Cleaning
Due to fog residue, smoke, and dust cleaning the internal and external optical lenses must be carried out
periodically to optimize light output.
1. Use normal glass cleaner and a soft cloth to wipe down the outside casing.
2. Clean the external optics with glass cleaner and a soft cloth every 20 days.
3. Always be sure to dry all parts completely before plugging the unit back in.
Cleaning frequency depends on the environment in which the fixture operates (i.e. smoke, fog residue, dust,
dew).
Unit not respond to DMX:
1. Check that the DMX cables are connected properly and are wired correctly (pin 3 is “hot”; on some other
DMX devices pin 5 may be ‘hot’). Also, check that all cables are connected to the right connectors; it does
matter which way the inputs and outputs are connected.
