Paramount’s N-MCDC2-P for Pocket Wizard to Nikon 4-Pin Pre-Trigger Motor Drive Cord for Nikon D90 and D5000. This pre-trigger cable connects to the camera’s remote cable socket, and enables your radio slave to trigger the camera’s shutter remotely. This cable is designed to keep the camera constantly “awake”, and has the same effect as holding the camera’s trigger button pressed down half-way.

A camera will trigger much faster in the “awake” mode, but will also use up more battery power. This cable is 3 feet long, and will trigger Nikon DSLR cameras with the 4-pin remote socket (e.g. D90 and D5000 (not D70, D70S, and D80). Works with any Nikon camera that accepts the Nikon MC-DC2 trigger cord.
