I have a CM-222 change machine that I have updated the bill validator.
It did have a JCM DBV20 and I upgraded to an ICT BL-700.
The pinouts are very simple: 12v power, 5-12v inhibit (out of quarters, show 'no more change'), and 12v vend (the dollar is good, send a 'vend' pulse signal).
I want to update the tubes hopper and need to see how it sends a pulse for a verified dollar, but I can't seem to figure that out.
Nothing shows up on the vend line that I can see, but it does in fact properly vend and give change.
What am I missing?
