The projector’s REMOTE Output isused todaisy-chain the
Remote signal when you want touse asingle Emergency
STOP Remote tocontrol multiple systems.
After a power failure or interlock failure (open circuit)
has occurred and been corrected you need to manually
reset laser emission bypressing the START button onthe
E-STOP Remote. Laser emission will then beavailable after
a60 second delay.
3. Safety key switch.
The Safety key must be inserted
and turned to ON position in order
toenable the system tooperate.
4. DMX Input/Through.
Use these ports to connect DMX
control signal or to daisy chain the
DMX signal between multiple laser
display systems.
5. Ethernet.
Use these ports to connect PCcontrol
signal or to daisy chain the control
signal between multiple laser display
systems.
6. FB4 laser control interface.
The inbuilt control interface allows
you to control the laser via Ethernet
and DMX/ArtNet, but italso handles all
the basic settings ofthe laser system
(master size and positions, method
of control, colour settings etc.). All
of these settings can be accessed
through the menu using the endless
rotary knob and once saved, they are
stored onincluded mini SDcard.
7. Colour Balance display mode
switch.
When the Colour Balance display
mode isactive, all the colours displayed
by laser will match those you see
on the screen in your laser software
(they can vary slightly, depending
onyour display and its colour settings).
The on& o setting ofColour Balance
mode is immediately stored in the
internal memory ofthe laser projector,
so next time you power it up, the
Colour Balance mode is set to its
latest state automatically.

The intent of laser manufactures is to produce a laser
diode driver with aslinear response behaviour aspossible,
sowhen the diode current increases, the optical power and
light intensity grow linearly. However, the human eye senses
brightness of light logarithmically over a moderate range
(Weber–Fechner law). Sowhen light intensity grows linearly,
human eye and brain doesn’tperceive itasalinear increase,
and our visual perception ofcolours changes.
Inthe world oflaser display systems this generates challenges
when wework with mixed colours (i.e. yellow, magenta etc.).
Normally the mixed colours coming out of laser systems
donot directly correspond with those wesee oncomputer
screens – because of the dierence in visual perception.
Inorder tosynchronise all the colours wesee onour screen
and those coming out ofthe laser device wedo,socalled,
palette calibration procedure inthe laser control software. This
can beofcourse rather lengthy process and even ifit’sdone
properly, the calibrated palette will always betied toparticular
control system or profile that was used during the colour
calibration and not tothe laser projector itself. Sowecame
with the idea tohard-code the “calibrated palette” into every
Spectrum laser system inour factory during the manufacture.
No matter what control interface you use or what control
signal is used (Ethernet, DMX, ILDA), the calibrated palette
isalways there, ready for you tobeswitched onbyColour
Balance button.
8. ILDA INPUT/OUTPUT.
ILDA INPUT connector isused for the
control signal input from an external
control interface. ILDA OUTPUT
connector is used to daisy chain the
control signal between multiple laser
systems.
9. Safety eyelet.
Use this together with appropriate
safety wire to secure the system
against unexpected fall.
