Dmx Address Setting; Cleaning And Maintenance - LCG PARBAR QUAD User Manual

7. DMX address setting

Each fixture must set a specific starting address. When receiving signal, fixture will
receive channel control signals of this address from the DMX controller.
For easy to use, the user can set the same address for several fixtures , also can set up a
unique address for every device.
If you set the same address for all fixtures, all the fixtures will receive from the same
DMX channels signal. All connecting fixtures are jointly controlled, controller can't
separate control a device.
If you set a different address for each fixture, each fixture will receive unique signal
and can be controlled by DMX controller separately.
This fixture has 20 channels.you should set the starting address of the first unit to 1, the
second unit to 21(1*20 + 1), the third unit to 41 (2*20+ 1), and so on.
DMX-512 connection with DMX terminator
If there are many lines or lights, it is recommended to use a DMX terminator to
prevent DMX signal corruption, the DMX terminator is an simple XLR plug with a
120 Ω resistor connected between pins 2 and 3,which is then plugged into the output
XLR socket of the last fixture in the chain.

Cleaning and maintenance

8.
The following points have to be considered during the inspection:
1). All screws of the device have to be tightly connected and must not be corroded.
2).There must not be any deformation on housings, fixations and installation
spots(ceiling, suspension,trussing).
3).Mechanically moving parts like axles,eyes and others must not show any traces of
wearing (eg: material abrading or damages)and must not rotate with unbalances.
4).The electric power supply cables must not show any damages,material fatigue(eg:
porous cables) or sediments.
5). Please use wet cloth to clean the housing. Glass cleaning liquid is suitable, never
use alcohol or solvents!
Further instructions have to be adhered by a skilled installer to prevent any safety
problems.
The cooling-fan should be cleaned monthly. The interior of the fixture should be
