QM2OOO--to--QM32-style adapter cable
Caution
Pangolin supplies an optional adapter cable to go from the QM2000's ILDA-compatible connector to an older-style QM32-compatible Pangolin connector.
     This is NOT an ILDA-to-Pangolin adapter. The QM2000 has special circuitry which works with this adapter cable. If you plug the cable into a standard ILDA source, the cable cannot convert ILDA into a Pangolin-level signal.

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.
