ILDA Gem Pocket
Power up
To power up the ILDA Gem Pocket simply press the power button momentarily. As the unit starts, the scanner output and
colour signals will be enabled. Note if the pots are all set to zero there will be no visible output but you should be able to
hear the scanners running.
The ILDA Gem Pocket will also apply a +5V signal to the ILDA shutter connection to ensure that if a shutter is in use it will
be opened when the Ilda Gem Pocket is powered on.
When the power button is depressed, if the unit fails to start it normally indicates a low battery. (see power management
section below)
Normal mode
Normal mode can be used to test the modulation of the laser modules, match several projectors to the same output size or to output a
safe low power beam while aligning or adjusting a projector, all without the use of a computer and laser controller.
Please note any button press will cause the scanner and modulation outputs to cease.
Following start-up the scanner and colour output will be enabled and the quadrature test pattern will output to the scanners.
The colour outputs are always set to variable levels on power up or whenever normal mode is entered. Note if the pots are
all at zero the output will not be visible. Adjust the pots to the desired level and the square test pattern will be visible. The
test pattern will output at aprox. 50% scanner output scale set on the scanner amplifier, therefore the output scale of
multiple projectors can be matched. Pressing one of the coloured buttons will remove the voltage on the matching colour
line turning the corresponding laser output off. A second push will turn the corresponding colour channel to full power and a
third push of the same button again will return variable level output for level adjustment by the pot. This cycle is repeatable
on each of the three channels.
From the factory the ILDA Gem Pocket will output to the scanners at a rate of18kpps, the scan rate can be changed at any
time by the user (see extended operation modes below).
Note: Laser modules with low impedance on the modulation inputs may result in the output being loaded and therefore not
be able to maintain full 5V output on the ILDA Gem Pocket colour lines.

Laser projector tool Instructions
V1.04 January 2014
The ILDA Gem Pocket is an easy to use battery powered pocket sized version
of the popular laser projector test tool the ILDA Gem from Stanwax Laser. Using
the latest digital technology the ILDA Gem Pocket will provide a long life while
running from a single 9V alkaline or lithium battery and is housed in a rugged
ABS housing with silicone rubber protective boot available as an optional extra.
The ILDA Gem Pocket has on board quadrature pattern generator that will
output a quadrature (square) test pattern to your scanners at one of four user
selectable scan rates.
The simple controls consist of three pots and five push buttons plus three
indicator LEDs. (see image right)
The pots allow the colour levels to be constantly variable between 0 and 100%,
and buttons are provided to switch the outputs to full power. Red green and
blue LEDs are provided to indicate full power output. Other output options are
orientation mode and static beam mode. In addition to this there are four user
selectable scan rate settings
.
Operation
The ILDA Gem Pocket is a simple tool to use but we would advise that you
should familiarise yourself with its controls and modes by reading this manual in
full before use.
Connect the 25 way sub-d female connector of the ILDA Gem Pocket to the
laser projector using a 25 way ILDA standard lead, or the optional ribbon cable
if purchased
.
