Thank you for purchasing Stanwax Laser ILDA Gem laser projector tool.
The ILDA Gem is a simple device that is essential for the toolbox of any laser pro or amateur and allows you to operate a
laser projector for set-up, testing or alignment without having your laser hardware and computer operational. Onboard
there is a quadrature generator that will output a single ended signal to the X/Y lines. The board outputs either a full 5V or
a variable level (0-5V) to the modulation signal lines (up to 6 lines). All this can be achieved with the device powered from
the supplied USB power adaptor or you can connect a laser controller to the device allowing the same 5v or variable level
to the modulation lines while displaying an ILDA X/Y signal from your laser hardware.
Powering the ILDA Gem
The board must be powered up using the supplied power adaptor cable, which can be plugged into any computer USB
1.0, or 2.0 socket or have its power provided by connecting it to the optional mains power adaptor. The board requires 5V
dc at <5mA so will not adversely load a computer USB socket.
Operation using the supplied power adaptor
When the board is powered from the supplied power adaptor the on board quadrature generator will operate and will
output to the scanner X/Y signals of the projector. The generator will produce a single ended quadrature output (square
pattern) at aprox. 18kpps. As its output is single ended the square will be output in one of the four quadrants of the
normal projector output area (see image below) The quadrant in which the output will appear will be dependant on the
wiring and configuration of the laser projectors scanners. This action is normal.
The board layout can be seen in the image right.
The 3 slide switches select full 5V output when moved toward
the output connector this is useful for testing the full power
output of the lasers in a projector. When the slide switches are
moved towards the input connector the level that is fed to the
colour outputs is controlled by the 3 pots providing a lower level
output. This is useful for alignment or fine adjustment purposes
making these tasks much safer.
The switched colour lines can also be routed to the additional
user defined colour lines (as per Ilda standard) by way of the 3
sets of solder links at the edge of the board as indicated (right).
The factory setting is for these solder pads to be left unused. If
they are utilised, each line must only be joined to one output or
damage to the board may occur.
Solder pad set UD1 is connected to Ilda pin 8, UD2 to pin 9 and
UD3 to pin 10. Each of these can receive its signal from the red
green or blue signals from the switches and pots.
Output will be in one of the four quadrants
shown above
Operation with an ILDA signal
If using an Ilda signal from a laser controller such as QM2000 or FB3
then power is supplied from the shutter signal line therefore the ILDA
Gem will only output a signal to the modulation lines in this mode when
the laser output is enabled in the software. When an ILDA signal cable
is attached then the onboard quadrature generator will automatically be
disabled and scanner output will be provided from the laser controller.
In this mode the laser controller hardware will NOT provide blanking to
the modulation inputs of the projector, the slide switches and pots on
the Ilda Gem board will provide these signals.
