The PocketWizard N-MCDC2-ACC-1 Pre-trigger remote cable is used to connect a PlusX, Plus III, Flex TT5, or MultiMAX with ACC port wireless transceiver to the Nikon MC-DC2 remote terminal. The cable helps control the half press and full press functions of the camera's shutter release mechanism remotely. It allows a compatible PocketWizard radio to control the half press and full press function independently. The cable comes in two lengths of 1 foot (30 cm). It is packed in a box made of completely recycled paper that is eco-friendly. The white label on the box shows both the ends of the cable and also gives you a list of equipment that works with this cable.
