DMX-512 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
output XLR socket of the last fixture in the chain. Please see illustrations below.

Projector DMX start address selection
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.
