Does the UP4 Reciever fit between the camera and the Anton Bauer battery and reciever will be powered by the A/B battery?
Per Paul Sullivan of Anton Bauer:
To mount the UP4 receiver to an Anton Bauer Gold Mount battery requires two products from Anton Bauer:
A) One Backplate; there are two models - one for a Sony camera, the other for a JVC or Panasonic camera.
B) One ABWMK-KIT universal wireless receiver mounting kit. The UP4 mounting box attaches to this piece.
The UP4 does have an DC power jack for powering from an external battery.
