Wooden Camera brand V-Mount plate utilizing an IDX V-Mount and Blackmagic URSA Molex connector. Blackmagic URSA V-Mount works with all models like EF, PL, B4, etc. Special Molex connector attaches directly to back of Blackmagic URSA and is covered by the plate eliminating external cabling. 1x D-Tap ports 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 utilze a second D-Tap.
