Polaroid Sonar for robot

I got these two modules from mondotronics,
and I need some help making them work.
I can get them to click, but I can't
seem to obtain a reading that makes
any sense with my BSII.
I'm raising the init line to send
the clicks, then using RCTIME afterwards
to try to get the 'echo' line pulse
afterwards.
I'm obtaining some pretty meaningless
readings.
Yes, the grounds are tied together on
TWO different supplies. The 4AA nicads
are for the module, and the 9v is for
the stamp.
