#SmallRig Data Cable for BMPCC 4K / 6K Cage 2960

The SmallRig Data Cable for BMPCC 4K / 6K Cage (Model 2960) is a highly specialized, ultra-flexible 2-in-1 electronic routing accessory designed to work alongside SmallRig's specialized cinema cages for Blackmagic Design cameras (such as SKUs 2203B, 2254B, and 2255B).

Because the Blackmagic Pocket Cinema Camera 4K and 6K output massive RAW video bitrates, filmmakers rely heavily on external Solid-State Drives (SSDs) and uncompressed external on-camera monitors. Running standard, stiff consumer-grade cables directly out of the side of the camera creates a wide, unwieldy rig footprint and risks breaking the camera's delicate logic board connectors. The 2960 cable pack resolves this by offering a custom-molded, right-angle layout that streamlines cable routing while physically anchoring to the camera cage.

Core Engineering and Structural Features

• Custom-Spaced 2-in-1 Interface Block: The camera-side end of the accessory houses both a Full-Sized HDMI (Type-A) male connector and a high-speed USB Type-C male connector inside a single, custom-molded PVC block. The distance between the two jacks is mathematically matched to the exact physical layout of the BMPCC 4K/6K input panel, allowing both lines to be plugged in simultaneously with a single movement.

• Anti-Shedding Mechanical Cage Anchor: Unlike loose consumer cables that easily wiggle or drop connection under friction, the 2960's connector block features a built-in stainless steel thumbscrew. This screw runs straight through the housing and fastens securely into a matching threaded hole on the left side wall of compatible SmallRig cages, mechanically locking the data pins in place.

• High-Bandwidth Multi-Protocol Transmission: The internal wiring traces are heavily shielded to protect structural data transfer rates. The USB-C extension fully supports the strict bandwidth metrics required to capture uncompressed 6K or 4K Blackmagic RAW (BRAW) data streams directly to external drives without frame skipping, while the HDMI bridge handles pristine video monitor feeds up to 4K.

• Ultra-Flexible Ribbed Cable Design: Rather than standard thick, round plastic insulation, the trailing lines utilize a flat, highly flexible ribbed cable profile. This design allows the cables to be bent sharply, tucked around corners, or wrapped flat against the side of the cage without placing mechanical tension on the cable heads.

💡 Operational Rigging Tips for the 2960 Data Cable

The Sequential Alignment Rule: When installing this dual-cable block, do not tighten the integrated cage anchor screw immediately. First, align the HDMI and USB-C male pins with the camera's side inputs and slide the block straight into the sockets until it sits completely flush against the camera body. Once the electronic pins are safely seated, use your fingers (or the flathead slot) to gently tighten down the side locking screw against the cage wall. Forcing the screw in first can angle the block slightly, bending or breaking the micro-pins inside the camera's input sockets.

• Eliminating Signal Drops in High-Bitrate BRAW: The BMPCC 4K/6K pushes immense data packages when writing 5:1 or Constant Bitrate RAW files. While the 2960 adapter provides a locked, stable bridge on the camera side, the opposite end leaves you with female HDMI and USB-C sockets. When extending the line to your storage drive, always use a short, certified 10Gbps USB 3.2 Gen 2 or USB4 cable (such as the original short cable bundled with a Samsung T5). Using long, thin, unshielded consumer charging cables between the adapter and the SSD will cause data bottlenecks, forcing the camera to drop frames or stop recording abruptly.

• Clearing Access for the 3.5mm Audio Jacks: Because this adapter merges the HDMI and USB-C lines into a single solid block, it sits directly adjacent to the camera's native 3.5mm microphone and headphone inputs. If your audio setup requires wide, L-shaped 3.5mm mini-jacks, plug your audio lines into the camera before sliding the 2960 block into place. The low-profile, right-angle bend of the 2960 cable will exit downward or backward, cleanly wrapping past your audio lines without crimping them.
