This MicroSync Motor Drive Cord will allow you to trigger any camera, flash, or other device using the 2.5mm subminiphone connection wirelessly-at a distance of up to 100 feet (multiple factors affect triggering range).
This cord's actually properly specified as male 2.5mm subminiphone 'mono' to male 2.5mm subminiphone 'stereo'. One end (the 'mono' end with 1 black sleeve upon tip) connects to the MicroSync receiver, and the other ('stereo') end of this cord connects to the camera.
