Caution!
Pins 1 and 2 are connected to the derived DC power for the unit, and can be used as an external power feed for
external equipment, such as an infrared sensor. When connecting other equipment using this connector, the
maximum current of 50mA must be strictly observed. Failure to do so may cause a loss of power to the unit and may
even damage your camera.
