ENGLISH
 To assure proper operation you need an optional "Mini DMX-SPLITTER" to isolate the master/slave line
from the main DMX-line, see drawing.
 Connect 2 or more units together using good quality balanced microphone cables. The first unit in the
chain must be set as the master, the other units must be set as slaves.
 Set the master to 1MSL channel mode (see previous chapter).
 For the DMX-controller the master and his slaves can now be considered as 1 virtual effect that needs a
start address so it can be controlled as any other DMX-unit in the DMX chain: see "DMX Address" in the
chapter "Main Menu" to see how you can set the DMX-start address.
 Make sure that all units are connected to the mains.
 Set the DMX-controller according to the DMX-chart below.
 Done!
Remark: in order to work well to the rhythm of the music, make sure that the option "Sound State" on the
master is set to "On" (see previous chapter)
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 balanced cable of good quality.
 Both XLR-3pin and XLR-5pin connectors are used, however XLR-3pin is more popular because these
cables are compatible with balanced audio cables.
Pin layout XLR-3pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+)
Pin layout XLR-5pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+) ~ Pins4+5 not used.
 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 starting address so it knows
which commands from the controller it has to decode.
 HOW TO SET 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.
