DMX Start Address
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 this LED moving head, which is a 15 channel fixture, you should set the starting address of the first unit to 1, the
second unit to 16(15 + 1), the third unit to 31 (15+16 ), and so on.
DMX Connection with DMX 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 outp
ut
XLR socket of the last fixture in the chain. Please see illustrations below:
