Has anyone hooked up a custom output to signal you when knock is occuring? I was thinking about either putting an LED light on the output or a buzzer. Can it be run directly off the output or do you need to trigger it with a relay?
I think this would work:
Enable
[PID.2630]>0.1 (2 frames required)
Disable
[PID.2630] = 0.0 (20 frames required)
