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.
