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 & off 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 difference 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.
