Description

D-Box (URSA Mini, V-Mount) is a custom version of our popular D-Box that adds power distribution, standardised remote start/stop, and hot swap abilities for the Blackmagic URSA Mini Pro, EF, PL, B4, etc cameras. The D-Box attaches directly to the back of the camera body using a special Molex connector eliminating external cabling. It also interfaces with the rear LANC port which is how the D-Box controls the camera's run/stop.

Connectors on the D-Box are contoured to match the URSA Mini's which allow for all cables to be installed with no collisions. The module communicates with the camera and allows any ARRI standard start/stop trigger to be used with the 3pin Fischer port. The DC input on the D-Box is a Mini 4pin XLR and the kit also includes a pigtail cable which converts to full size 4 pin XLR (same as the camera's) allowing for an AC Power Supply or External Power Plate to be connected to power accessories and camera during a battery change. When both battery and DC input are utilised, the D-Box defaults to the DC input, leaving the battery fully charged.

Overview:
Authentic IDX V-Mount plate provides 2x D-Tap (unregulated) on the power plate itself but we should note that one D-Tap may be obscured by the right side BNC connectors when in use. The camera receives an unfused connection to the power source and the D-Box connectors share a 7.5A fuse. When using D-Box battery modules it is important to know what amount of power your batteries are capable of providing.

Most high-end cinema batteries can supply up to 10A with the URSA Mini camera generally consuming 3-4A in standard configuration. Although the remaining power is available from the D-Taps, LEMO compatible connectors, Fischers, etc., it is best to limit the power draw to 5A or less for best results. Consuming more power than a battery is capable of providing will cause the battery to shut itself off, killing the camera and accessory power.
