I need more information concerning this excerpt from the Power Expander Pro's User Guide:
All receiver channels have each servo signal output individually buffered. If a servo were to short out its signal wire, the other servos on that channel would not be affected.
I take this to mean, in my own words, that if the signal wire on a servo shorts out to the servo wire's positive or negative power wire, then all the other servos on that same channel (same channel, but different Power Expander output port) and all the servos on any other channel's output port will continue to receiver normal battery power and normal receiver signal. In addition, the battery or batteries will not be affected (typically by attempting to deliver more electrical power). Is this correct?
Also, what if one of the servo's power lines shorts out to the other power wire (not the signal wire)? Is this managed in a similar manner?
