This is a special remote shutter release cable called a Pre-Trigger Cable. A Pre-Trigger cable controls both the half-press and full-press function of your remote camera's shutter release. When a camera is “pre-triggered”, it is like holding your camera's shutter release button in the half-pressed or metering/focusing position.

This ACC cable allows a compatible PocketWizard radio to independently control both half-press and full-press functions.

• For connecting a PlusX, Plus III, Plus IV, FlexTT5, FlexTT6, or MultiMAX with ACC port to a Sony or Minolta remote shutter release terminal.
  
  
• Cable lengths: 3' (91 cm) and 1' (30 cm)
  
  
• From 1/8" (3.5 mm) stereo miniphone
  
  To Sony's cameras with the RM-S1AM remote port or Minolta's cameras with the RC-1000 remote port
  Note: NOT for camera's with Sony's multi/micro USB port

Compatible with the following radios:

PlusX: Use this cable with the PlusX to trigger the camera.

Plus III: Use this cable with the Plus III's exclusive 2-stage trigger to wake-up or focus your remote camera just like using the camera's shutter release button.

FlexTT5 / FlexTT6: This cable is required for relay mode with E-TTL, or other remote triggering with the FlexTT5. Learn more here. You can use a –P cable or standard cable with a FlexTT5, but your remote camera will not be able to relay an E-TTL signal to Speedlites. The FlexTT5 does not support the 2-stage trigger function.

MultiMAX with –ACC port: Enable a remote zone with your hand-held MultiMAX, and your remote MultiMAX will wake up its remote camera with this cable. As long as the zone is turned on, the remote camera will stay awake and respond more quickly and consistently, but also consume the camera's batteries much more quickly. When the remote zone is disabled, the camera will enter its normal sleep modes. The MultiMAX does not support the 2-stage trigger function.
