Vello FreeWave Viewer VL AV & Shutter Release Cable for Nikon D3100, D90, and D7000

The FreeWave Viewer VL AV & Shutter Release Cable for Nikon D3100, D90, and D7000 from Vello will connect your camera to the FreeWave Viewer VL transmitter and allow the transmitter to send a live preview feed to the viewer. One end of the cable connects to the transmitter, and the other end to the camera. The side of the cable that connects to the camera splits in two; one side is a 3.5mm AV connection for sending the video signal to your viewer, and the other is a DC2 connection for the shutter release to fire the camera.
