X-Band Motion Detector module # 32213, schematic

Where do I get a schematic for the X-Band Motion Detector module #32213? There is a place for the schematic in the documentation file, but it appears to be left out of the document. If a complete schematic isn't available, I need to know exactly what type of output it has (because I do not intend to use it with any sort of microcontroller on the OUT pin).

TIA

    Communication: High (3.9 V) / low (0 V) signal oscillates with motion
    From page 1 of the documentation.

    Hi Franklin.

    I can read too, and I saw the comment about the digital output. But, that isn't much help.....

    Does the output only go high if motion is detected, or does it output a pulse width that is related to the speed of the motion? If the doppler is 80 Hz, do I get 80 transitions every 1 second, or just a single transition?

    I think the answer is in the examples of the code given, but I don't do programming so I can't interpret those examples. I'm also wondering how similar the 32213 is to the GH719, which is currently available from other vendors.

    I did order one, hopefully I can figure it out when the hardware arrives.

    Regards,
