The Photon Replicator Kit includes a Photon Replicator Board, as well as a wearsaver and rear cover, that emulates the 15-pin D-sub electrical interface to Photon 320. A "horseshoe" shaped bracket is also included that, when attached to the Tau, exactly mimics the mounting scheme of the Photon 320 camera.
The Photon Replicator Kit was designed for the Tau 320. Although the kit will work with the Tau 640, digital data cannot be passed through the wearsaver connector since more data lines are required for the 640 than the 320. The remaining interfaces are compatible: power, analog video, communication.
