Power Status: A high level on this output indicates that
the camera power is switched on (+5 V = on, 0 V = off).
GND: System digital ground. Any external circuitry
intended to interface with the trigger control signals must
reference this ground connection.

Shutter Output: TTL output for timing of external shutter
driver. Signal is high during Shutter Open Delay and
exposure time. The pin does not provide power to drive the
shutter directly, so an external shutter drive controller is
required.
