The operator has to make sure that the safety-relating and machine-technical
installations are approved by an expert before using them for the first time. The
installations should be inspected every year by a skilled person to be sure that safety is
still optimal.
CONTROLLING THE DUALSCAN
1. Standalone 1unit:
Just connect the unit to the mains and put on some music. The unit will start working
automatically to the rhythm of the music.
2. Two or more units in master/slave setup:
Connect 2 or more units together using good quality balanced XLR microphone cables
(like for example JB Systems code 7-0063). The unit that has no cable connected to its
input will react as master; the others are the slave units.
Don’t forget to set the DMX addresses as follows:
•
Master unit:
DMX start address MUST be set to 001. (first DIP switch = ON, all other
are OFF)
•
Slave units:
DMX start address may have any value but NOT 001 (example: set the
first 3 DIP switches to ON)
It is possible to inverse the behavior of a slave unit by changing the position of DIP-
switch n°10. Just try it and see if the effect becomes better. Changing DIP-switch n°10
on the master has no effect.
3. Connect the optional CA-8 controller for more control:
The CA-8 controller can only be used in standalone or
master/slave mode. Connect the controller to the jack input of
the first unit (master). Now you can control all the connected
units:
•
STANDBY BUTTON:
Press this button to start/stop blackout mode on all
connected units. The led is ON when the blackout function is
active. After about 30sec. blackout, the lamp will be switched
off automatically to extend its lifetime.
•
MODE/FUNCTION BUTTONS:
With the MODE button you can select 3 different modes:
•
The LED is off:
with the FUNCTION button you can
select 2 different strobe functions.
•
The LED is blinking:
with the FUNCTION button you can
select 6 different X/Y moving patterns.
•
The LED is on:
The beam movements are sound activated. With the FUNCTION
button you can select the desired gobo/color.
4. Controlled by universal DMX-controller:
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 (ex. JB Systems ref. 7-0063). To
prevent strange behavior of the light effects, due to interferences, you must use a 90

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 DIP-switches to obtain the right starting address:
On the back of the Dualscan you will see that each of the first 9 DIP-switches
corresponds to certain value:
Dip #1 #2 #3 #4 #5 #6 #7 #8 #9
Value
1 2 4 8 16
32 64
128
256
You can combine the values of these switches to become any starting address
between 1 and 512:
Begin address = 01
Æ
switch 1=ON
values: 1
Begin address = 05
Æ
switch 1+3=ON
values: 1+4 = 5
Begin address = 09
Æ
switch 1+4=ON
values: 1+8 = 9
Begin address = 13
Æ
switch 1+3+4=ON
values: 1+4+8 = 13
Begin address = 62
Æ
switch 2+3+4+5+6=ON values: 2+4+8+16+32 = 62
