tried searching for but can't seem to find info on PWM channels and what controls them? I just see them changing on the portal dash board??? also, what exactly does the dc pump duration do? I presume it's pulse duration? would like some help as i'm not sure how to utilize both pulse duration and PWM channels effectively.

as well, is there a link to dc pump wave patterns so I can understand what they do?

thanks a bunch
