terminator

For installations where the DMX cable has to run a long

distance or is in an electrically noisy environment, such

as in a discotheque, it is recommended to use a DMX

terminator. This helps in preventing corruption of the digital control signal by electrical noise. The

DMX terminator is simply an 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. Please see

illustrations below.

All fixtures should be given a DMX starting address when using a DMX signal, so that the correct

fixture responds to the correct control signals. This digital starting address is the channel number

from which the fixture starts to "listen" to the digital control information sent out from the DMX

controller. The allocation of this starting address is achieved by setting the correct number on the

display located on the base of the device.

You can set the same starting address for all fixtures or a group of fixtures, or make different

address for each fixture individually.

If you set the same address, all the units will start to "listen" to the same control signal from the

same channel number. In other words, changing the settings of one channel will affect all the

fixtures simultaneously.

If you set a different address, each unit will start to "listen" to the channel number you have set,

based on the quantity of control channels of the unit. That means changing the settings of one

channel will affect only the selected fixture.

In the case of the moving head, which is 6channels fixture, you should set the starting address of the

first unit to 1, the second unit to 7(6 + 1), the third unit to13 (6+ 7), and so on.
