The voltage levels are:
x Low Level: <0.65 V (-20 Vdc Absolute Min)
x High Level: >2.0 Vdc (+20 Vdc Absolute Max)
Leaving the External Trigger signal in the active state prevents the camera
from entering into a low powered state. If an external device is allowed to keep
the camera in its Fully On State, power consumption will be greatly affected.
When the camera is fully on and no other process is occuring, the time from the
transition of the signal from inactive to active, to the time a picture is captured
or video is started, is typically less than 100 msec. The parameter descriptions
for the External Trigger setup are outlined in Tables 12-6 and 12-7 External
Trigger Variables for Photos and External Trigger Variables for Videos,
respectively.
