Figure 4-10: WakeUp lines
There are two WakeUp Lines. Both WakeUp lines can be
input
and
output

WakeUp Line 1 Actuator
: If this box is checked, this wakeup line provides the
same voltage as the voltage on the powerline (kind of loop through). It
provides power as long as there is a reason to stay awake.
WakeUp Line 1 Actuator
: If this box is unchecked, this wakeup line is only
input and wakes up the device when supplied.
