The PocketWizard CM-N3-P Pre-Trigger Motor Cord, Canon 3-Pin to Miniphone is a 91.5cm cable that allows you to connect your PocketWizard to your Canon EOS Camera. This will allow you to trigger the shutter through the wireless device. This cable is not designed for use with the Flex TT5. Unlike the CM-N3, this cable will continue to communicate with the camera making it always available for response.
