Blackmagicdesign Blackmagic Cinema Camera, Installation And Operation Manual

Page: 18 / 409

5 B4 Communication
The DB-9 connector allows you to power and control B4 broadcast lenses attached to
the Micro Studio Camera 4K via an MFT to B4 adapter. To control a compatible B4 lens,
simply connect the optional Digital B4 Control Adapter cable to the cable from the lens,
then connect the other end to the DB-9 serial connector on your expansion cable.
You can adjust settings such as iris, focus and zoom in the same way you would an
active MFT lens, either via an ATEM switcher using the ‘camera control’ page, or via
other remote control interfaces that can be connected to the Micro Studio Camera 4K
expansion cable. For a list of supported B4 digital lenses, refer to the Blackmagic
Design support center at www.blackmagicdesign.com/support/faq/59011
6 S.Bus Digital Servo
By connecting to a compatible S.Bus receiver using the Futaba J cable, you have 18
S.Bus remote channels where features of the camera can be assigned to and remotely
controlled. These features can include focus, servo zoom, iris control and other such
features. For more information about mapping functions to S.Bus remote channels, see
the ‘Remote Settings’ section of this manual.
Wiring diagram for the Blackmagic Micro Studio Camera 4K
Expansion Cable
When using Blackmagic Micro Studio Camera 4K’s expansion port you may only want to access
one or two functions. For example, you may want to control an attached B4 Broadcast Lens
while simultaneously receiving 12V power and a reference signal. It’s easy to make a connector
that will give you just these functions without the clutter of additional, unused connectors.
Use the following diagram when wiring the expansion cable included or use it as an example for
how you can wire up the connections on your own custom cable correctly. The full range of
available pins are listed under group P1, while the subsets used for particular functions, as well as
their layout within the appropriate connectors, are shown in groups P2 through P7.
