The WC V-Mount Battery Plate for Blackmagic URSA/URSA Mini/URSA Mini Pro Cameras from Wooden Camera features an IDX V-Mount and Blackmagic URSA Molex connector. The Blackmagic URSA V-Mount works with all URSA, URSA Mini, and URSA Mini Pro models. The Molex connector attaches directly to the back of the camera and is covered by the plate, eliminating external cabling. The plate features one D-Tap port for accessory power. Please note that the reason there is only one D-Tap on this plate is because the position of the BNC connectors on the rear of the URSA prevent you from being able to utilize a second D-Tap.
