Returning hardware to Pangolin
The chart below lists pins for the DB-25F female connector on the
QM2000. This connector conforms to the ILDA DB-25 connector
standard.
The ILDA standard uses
differential signals for projector inputs, primarily because they are more immune to noise. For
example, you will see X+ and X- signals defined below. The positive
indicates a normal signal; the negative indicates an inverted signal.
Projectors also use differential signals for color signals as well,
but the QM2000 generally outputs only single-ended OUTPUT signals
for colors. This is allowed by the ILDA Standard.
For more information, we recommend you read the
Projector Connections article.

Note on interlock lines A and B
The purpose of the two interlock lines is so that a
projector can tell when it is properly connected to an ILDA-compatible
signal source.
The projector will put a
current or signal into pin 4. The same current or signal should be present
back at the projector when reading pin 17. (This is because pins 4 and 17
are connected together on the QM2000 board.)
If no current or signal is seen
on pin 17, it means the DB-25 connector is not plugged into the projector.
