The PocketWizard PTMM Pre-trigger Adapter can be used to adapt an -ACC stereo miniphone remote cable to a mono miniphone pre-trigger cable. The adapter has a 1/8 inch (3.5 mm) mono miniphone male connector on one end and a 1/8 inch (3.5 mm) stereo miniphone female connector on the other. It allows you to wake or sleep your camera selectively, just like the way one uses the camera shutter button. The adapter is compatible with the FlexTT5, MultiMAX Plus III, Plus II, Plus X, and other older radios. It should be used with an -AAC stereo remote camera cable to convert -AAC cable to pre-trigger cable.
