 For MS2000/RM2000, the controller replies with the inverse polarity, <wrap reply> :A 1 </wrap> when the signal is low and <wrap reply> :A 0 </wrap> when the signal is high.  This is a logical bug in the firmware, but because it was in the field so long before being noticed we made the intentional decision to keep the behavior unchanged.
