The iPad Portal with Docking Station from Autocue/QTV is an adaptor which provides a composite video output from your 30-pin iOS iPad connector. It comes with a docking station and it is used in conjunction with iAutocue App and will allow you to feed prompting output from your iPad to any of Autocue's prompting displays. The ipad interfaces with the ipad via a 30-pin dock connector, but also requires a lighting adapter. A composite video BNC connector is included on the portal assembly.
