Jecod CP-40 hacking and DIY controller reverse engeneering

I just picked up a Jacod CP-40 gyre but was disappointing to see that the jabeo > apex connector does not work with this unit.. In efforts to figure out a way to work the signal and make my own i decided to do a little reverse engendering and see how it worked.. No keep in mind i’m still learning to use my oscilloscope.. this may be a bit of a leap for me.. but hey its a good time to learn!

Oscilloscope testing
Yellow line is the yellow wire. Blue is brown wire.
