Inversion and Return-to-Zero Properties of DIS

In a post awhile back you indicated that the DIS put out something like a
square wave whereas the HEI returned to the ECM a sequence of short pulses
(a return-to-zero type of coding). Did you ever verify that? I have also
heard that you must invert the signal back to the ECM from the DIS. Did you
ever verify that?
Thanks,
