ELECTRICAL INSTALLATION + ADDRESSING
Important: The electrical installation should be carried out by qualified personal only,
according to the regulations for electrical and mechanical safety in your country.
Electrical installation for 1 standalone unit:
 Just insert the mains cable. The unit starts working immediately in stand-alone mode.
Remark: You can connect a CA-8 or RF-8R (RF-8SET) remote controller to the unit if you want to have
more control. Refer to "how to operate the unit" to learn how to do this.
Electrical installation for two or more units in master/slave:
 Connect 2 to maximum 16 units together using good quality balanced microphone cables. The first unit
of the chain will automatically switch to master mode, the rest must be set to slave mode (SL1 or SL2).
See the previous chapter for more information.
 Make sure that all units are connected to the mains.
 Done!
Remark: You can connect a CA-8 or RF-8R (RF-8SET) remote controller to the master unit if you want to
have more control over the master/slave operation
Electrical installation 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.
 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. In the next section you will learn how to set the DMX addresses.
Traditional DMX-installation for normal use:
Connect the DMX-controller to all DMX-projectors and effects (like LED CROSSFIRE) in one long chain.
Don't forget to set the DMX-addresses on all units.

Special DMX-installation for use with the 1channel DMX MASTER/SLAVE function (1MSL):
Connect the DMX-controller to all DMX-projectors and effects in one long chain, except for the LED-
CROSSFIRE effects. These will be connected via a small (optionally available) "Mini DMX-splitter". As a
result the LED-CROSSFIRE effects can now work in master/slave mode while the master can still be
controlled by the DMX-controller via 1 DMX-channel.
Don't forget to set the DMX-addresses on all units. On the LED CROSSFIRE effects only the master needs a
DMX-address, the slaves will be controlled by the master.
 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.
