ENGLISH
 Connect several units together using good quality balanced microphone cables. The unit that has no
cable connected to its DMX-input is the "master", the others are the slave units.
 Make sure that all units are connected to the mains.
 Refer to chapter HOW TO SETUP for more information.
 Done!
Note: of course you can always add a foot controller or LEDCON-02 Mk2 to the master for more control.
Electrical installation for two or more units in DMX-mode:
 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 units with a good quality
balanced cable.
 To prevent strange behavior of the light effects, due to interferences, you must use
a 90Ω to 120Ω terminator at the end of the chain. Never use Y-splitter cables, this
simply won't work!
 Make sure that all units are connected to the mains.
 Each light effect in the chain needs to have its proper start address so it knows which commands from
the controller it has to decode. In the section HOW TO SETUP you will learn how to set the DMX
addresses. If for example you use the 4 channel DMX mode, a possible address setup could be: unit1 =
001 ~ unit2 = 005 ~ unit3 = 009 ~ unit4 = 013 ~ etc.
