A remote lens will always have a cable coming out of the housing. The black cable with the 9-pin female connector will connect to the Remote port on the back of the camera, or if using a Remote Positioner, it will connect to one of the serial ports on the Remote Positioner. There is an additional cable that will connect from the Remote Positioner to the Remote port on the back of the camera.
