You need to set your camera to FP mode to start in the camera menu. After that, either a 'D' adapter and transmitter, a Trio, a Pilot, or a CoPilot will all signal that a TTL device is present and enable beyond x-sync speeds. All those devices have multiple pin locking hotshoe mounts. As long as your remotes are set to 1/1.. either through one of the controllers or set manually on the remotes you will get sync right up to 1/8000s.
The X3d-R's should be pretty good as their flash duration is a long 1/250s.
