Bob,

The Renesis repair manual shows a picture of the signal in the CAS section.  It looks like a stretched out spring with two of coils stretched more than the rest, followed by more short sections and finally another stretched section of one coil.  There are 13 narrow coils followed by two stretched coils, then 12 narrow coils followed by one stretched section, then three narrow coils.  Below is my lame attempt to illustrate what it should look like. 

/\/\/\/\/\/\/\/\/\/\/\/\/\J\J\/\/\/\/\/\/\/\/\/\/\/\/\J\/\/\/\ 

You really ought to get hold of a Renesis shop manual.

Bob,

the coil trigger signal is supposed to be a square pulse of 5V amplitude and 2ms duration. I used this on the single rotor at one time, and it worked great.
FWIW.

Tracy is on vacation for a while and I need to find out what the coil
trigger pulse signal looks like.  Anyone know?

This is in reference to recalibrating John Downing's tachometer.  I
will publish what I've done as soon as I have it working.
