HOW TO CONNECT THE UNIT BY DMX
The DMX-protocol is a widely used high speed signal to control intelligent light equipment.
You need to “daisy chain” your DMX controller and all the connected light effects with a
good quality XLR M/F balanced cable. To prevent strange behavior of the light effects, due
to interferences, you must use a 90
Ω
to 120
Ω
terminator at the end of the chain. Never
use Y-splitter cables, this simply won’t work!
Each light effect in the chain needs to have its proper starting address so it knows which commands from the
controller it has to decode.
HOW TO SET THE THE RIGHT STARTING ADDRESS:
Refer to the previous chapter (DMX-512 address setting) to learn how to set the starting address on this unit.
The starting address of each unit is very important. Unfortunately it is impossible to tell you in this user
manual which starting addresses you have to set because this completely depends on the controller you will
use… So please refer to the user manual of your DMX-controller to find out which starting addresses you
must set.
