The D-Box for Blackmagic Design URSA Mini/Mini Pro (V-Mount) is a V-Mount on-camera power distribution plate that attaches directly to the rear of the camera body through a special Molex connector, eliminating external camera-power cabling while opening up a wider set of powered outputs. It carries three D-Tap ports, two 2-pin LEMO ports, two 3-pin Fischer ports and a 5V, 2A USB port, all simultaneously active and always on. A 4-pin mini XLR power input — supplied with a full-size XLR to mini XLR adapter cable — lets it run from an external supply, and a LANC connector attaches directly to the URSA Mini/Mini Pro to give camera start/stop control, matched by start/stop capability on the 3-pin Fischer connectors. Installation is tool-less, fitting straight onto the camera's battery mount without additional hardware. It covers the URSA Mini Pro 12K, EF, PL and B4 models, but is not compatible with the Blackmagic URSA Cine 12K or 17K.
