Connecting to Your Camera
Blackmagic Focus and Zoom Demands have two USB-C ports. This lets you use one unit
individually, or both units together.
Each unit is supplied with a 1 meter long USB-C cable which is connected directly from either of
your studio camera's USB-C expansion ports to the demand unit's 'in' port.
If you are using both demand units, daisy chain them together by connecting the first unit to the
second unit via USB-C.

Daisy chaining allows for both units to be controlled using one USB port on your studio camera,
letting you use the second port for an external USB flash disk. For example, connect a USB-C
cable into either of the camera's expansion ports A or B and connect the other end of the cable
into the focus demand's 'in' port. With a second cable, plug the focus demand's 'out' port into
the zoom demand's 'in' port.
The USB-C cable has locking screws on each end to secure the connectors to each unit,
preventing accidental disconnection. You don't have to use the locking screws, but they are
helpful for studio setups where the units are always connected to your studio camera.

without looking away from the screen
