B4 Lens
Introduction
The goal is to setup a lens control in parallel of the camera control.
Use case:
- when the camera cannot control the lens (dreamchip atom one + B4 ENG lens)
- the lens is not compatible (FX9 + cabrio lens) with the camera
When changing:
- iris/zoom/focus, we will send it to the lens
- shading, we will send it to the camera and it is transparent for the vision engineer on the RCP.
Wiring
ENG lens for specialty
Required cable : CY-CBL-6P-B4-01.

B4 lens for D-Cinema
Required cable:
- Canon CineServe and C-Motion Chrosziel : CY-CBL-6P-B4-01.
- Cabrio : CY-CBL-6P-FUJI.

Compatible Cyanview device
- CI0/RIO-live for local (LAN)
- RIO for remote control (internet)
note
Advantage of each solution:
CI0 is acting as a serial/IP converter. If the link between RCP/CI0 is broken or unstable, lens will not be controlled anymore and iris will close/reset.
RIO-live is a CI0, but with the brain of a RCP (all the protocol). If the link between RCP/RIO-live is broken or unstable, lens is still controlled by the RIO-live.
RIO same as RIO-live, but can control multiple cameras and has cloud connectivity.
Controls
- Iris
- Zoom
- Focus
Setup RCP/RIO
- Setup your camera as usual following one of the guide available (here, I will show the setup with an FX9)
- In the
configuration
tab, click on your camera - In the right tab, scroll down to
Lens
block:- Select B4 Generic
- Select your CI0/RIO and the port on which the lens is plugged
note
If you only need the Iris control and let zoom/focus controlled by the cameraman, on your RCP:
- Click on
Lens
, to open the lens menu - Click again on
Lens
, to open the second page of the lens menu - Click on
Z/F En
to disable it (onlyIris En
should be highlighted with white background)
This should looks like this:

And once correctly connected, it should be green:
