Signal connectors (see Fig.1)
3.1
Connecting Scanner- and Colorsignals
All signals are located at anILDA-standardconnector. This can be a 25pin D-Sub-connector (female)
or a 26pin IDC-connector, when the device should be mounted in a projector directly.
The IDC-connector allows to connect a separate D-Sub connector by using a flat cable.
All pins are routet 1:1, except pin 26, which has no function. Note the different pinnumbers of the
connectors. The wirenumber of a flatcable, starting with 1 at pin 1 corresponds to the pinnumber of
the DSUB connector (see table below).
Signals for X, Y and up to 5 c intensity are available.
Colour output 6 is internally connected to output intensity.
All colour outputs are single ended signals, referred to GND.
The maximum signal level is 5.2V (measured against GND).
Outputs X/Y are symmetrical, using a maximum voltage level of +/-5V per output pin.
This gives a total maximum output voltage of +/-10V between the signal pairs (+) and (-).
Important!
Never let one half of the signal pair unconnected.
If one part of the signal pair (+) and (-) is used only, maximum deflection angle of the scanner or
laser projector will be the half value only. Same happens if one of the signals will be connected to
GND.
Always connect the GND-pin (Pin 25 of the DSUB-connector) to your laser projector.
Question: Why are the signals of the new device different to the ones of the old EasyLase?
Answer:
The floating signals of the old Easylase allowed higher flexibility in use but created many
misunderstandings and problems with the users.
The new signal specification is easier to use, even with laser projectors which don't have a full
wired ILDA-connector.
