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 remote controller to the unit if you want to have more control.
Electrical installation for two or more units in master/slave:
• Connect 2 to maximum 16 units together using good quality balanced microphone cables (like for
example JB Systems ref. 7-0063). The unit that has no cable connected to its DMX-input will react as
"master", the others are the slave units.
• Make sure that all units are connected to the mains.
• When all units are connected together and switched on, you still have to address all units to obtain nice
multi channel chases. To do this just press the "auto DMX-address" button (indicated by number "6" on
the picture) on the "master" unit. All units will switch off and on again to indicate that the addresses are
set.
• Done!
Remark: You can connect a CA-8 remote controller to the master unit if you want to have more control
over the master/slave operation. You can also connect the LEDCON 01 remote controller, in this case all
units will respond equally (all units have the same color)

ENGLISH
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 (ex. JB
Systems ref. 7-0063).
• 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.
How to set the DMX addresses:
There are 2 ways to set the DMX-address of the units:
A. Automatic DMX-addressing:
To save a lot of time (imagine the time it takes to set the DIP switches of 16 units...) you can set the
DMX addresses of all units in the DMX-chain just by the push of a button. No need to calculate the
starting address of each individual unit, this will be done for you!
• Make sure the DMX cables of all units are connected.
• Connect all units to the mains so they are switched on.
• On the first unit (master unit) just press the "automatic address button" (6) once. All units will
switch off and on again to indicate that the addresses are set. Please note that the first unit in the
DMX-chain always receives DMX-address 001. Since each unit uses 4 DMX-channels, the 2nd
unit has start address 005, the 3rd has address 009, the 4
• Done!
Remark: you can mix the units with other DMX-effects that don't have the automatic DMX-
addressing option. In that case you still have to set the DMX-addresses of these DMX-effects
manually!
Hint 1: you can also make the DMX-address of each unit 001
the first unit, then press the DMX-address button on the second unit, etc... All units will receive
DMX-address 001.
Hint 2: You can also give the same DMX-addresses to several units in the same chain: if for
example you have 8 units connected to each other and you want 2 sets of 4 units, each with the
same addresses then you do the following: press the DMX-address button on the 1
will be addressed starting from 001 for unit 1. After this press the DMX-address button on the 5
unit: unit 5 to 8 will be addressed again starting from 001 for unit 5. Units 1+5, 2+6, 3+7 and 4+8 will
each have the same DMX-address.
B. Remote DMX-address setting by any standard DMX-controller:
An amazing feature is the "remote addressing system" that can be done with any ordinary standard
DMX-controller! Remotely you can set the start address of the first unit, all other connected units will
automatically receive their own addresses.
To do this you must program a chase containing 2 scenes, each with 4 channels. To set the starting
address you have to do a small calculation first using the following formula:
DMX Start address = (CH3 x 256) + CH4 + 1
In this formula CH3 can be 0 or 1 and CH4 can range from 000 to 255.
Some examples to make this clear:
• Start address = 010:
CH3= 0
• Start address = 257:
CH3= 1
• Start address = 403: CH3= 1

CH4= 0 [ (1 x 256) + 0 + 1 = 257 ]
CH4= 146 [ (1 x 256) + 146 + 1 = 403 ]
