Nikon D3300 Hidden Connections
Hidden under the covers on the left side of the Nikon D3300 are the following connection ports, labeled in the figure. Open the covers on the side of the camera to reveal these connections:
Accessory terminal: This terminal accepts the following accessories: Nikon MC-DC2 remote shutter-release cable; WR-1 and WR-R10 wireless remote controllers; and GP-1/GP-1A GPS units. The manual that comes with each device can get you up and running.
Microphone jack: If you’re not happy with the audio quality provided by the internal microphone, you can plug in the optional ME-1 stereo microphone here.
USB and A/V port: Through this port, you can connect your camera to a USB port on the computer for picture downloading. The same camera port enables you to connect the camera to a television via an A/V cable for picture playback. Nikon supplies the cables you need for both connections in the camera box.
If you buy the wireless mobile adapter WU-1a, you also use this port to connect the device to the camera.
HDMI port: You can use this port to connect your camera to a high-definition TV, but you need to buy an HDMI cable to do so. Look for a Type C mini-pin cable.
If you turn the camera over, you find a tripod socket, which enables you to mount the camera on a tripod that uses a 1/4-inch screw, plus the battery chamber.
